2025 1:8 GT World C/ship Chassis Focus Index

While some had their reservations regarding how the cars would perform around the large Club de Aeromodelos de Chile track and in particular its long straight, it would ultimately prove a huge hit with drivers at the IFMAR 1:8 GT Worlds and showcase the impressive speeds at which 1:8 GT cars now run.  The third running of the 1:8 GT World Championship, it was great to see such a diversity of manufacturers make up the World Championship deciding 1-hour final with 7 different brands forming the 11 car grid.  A very popular brand in South America, it was Italian manufacturer WIRC who was best represented with three cars, Brazil’s Flavio Elias going from winning the last chance final to finishing on the podium.  A brand which at the last World Championships was a solo personal project of its driver Michael Kocher, the Andrea Contarini designed car only offered then to customers as a eGT kit, Raptor has since through the involvement of Gimar become a major player with their star driver Alessio Mazzeo doing the World Championship double in Santiago.  In Nitro GT their two cars on the grid would go on to achieve a 1-2 finish.

Taking the TQ honours, Serpent would also have two cars in the final.  With one car each Senesi Motorsport, Xray and IGT8 completed the line up of different brands.  In terms of engines Gimar was the most popular with it powering 5-drivers.  While absent from the event as a car brand, Italy’s Genius Racing, who were Top Qualifiers in Sydney, proved the most popular body with 8 drivers running their GT Fury shell.  With Red RC able to make the very enjoyable and welcoming trip to South America to cover the GT Worlds for  a second time thanks to the support of Sweep tyres, Energy fuel, and 2023 World Champions Hong Nor, over the condensed schedule we managed to photograph 8 cars from 6 different manufacturers for our ‘Chassis Focus’ including the Top 2 finishers in the inaugural IFMAR 1:8 Electric GT World Championship.  As the supplier of the controlled tyre with is D-SPEC GT 40, Sweep came in for a lot of driver phrase for how its tyre performance as his Energy who fuelled everyone for the event.

Mazzeo becomes double World Champion in Chile

Raptor/Gimar driver Alessio Mazzeo has gone from being close in the past to becoming a double World Champion in less than 24-hours, the Italian taking the biggest win of his career today when he executed a flawless drive to win the IFMAR 1:8 Nitro GT World Championship final in Chile.  Winning the Electric GT World title yesterday in Santiago, and having hinted at what was to come as he put in a sterling performance in the battle for the Nitro TQ honours in the final qualifier, lining up behind Serpent’s eventually Top Qualifier Andrea Catanzani, he and Catanzani were the class of the field.  From the start of the 1-hour Main they pulled clear of the field around the Club de Aeromodelos de Chile track with it looking like the stage was set for a battle between the two different generations of drivers.  Unfortunately that anticipated fight to become the World No.1 lasted just four & a half minutes.  Catanzani would suffer a flame out and his demise was only the start of more problems to come for Italian drivers, the nation dominating qualifying and locking out all four direct qualifying spots in the main.  11-minutes in and Natanaele Senesi suffered the first of numerous flame-outs.  With Alex D’Angelo holding a comfortable second, just as Mazzeo put a lap on the Capricorn driver 36-minutes into the race, the 2023 Worlds Top Qualifier would come to a stop on track.  The issue proved terminal, his throttle servo having failed.  This promoted Carli Lopez to second making for a Raptor 1-2 on track.  Despite this being his first World Championships, the 21-year-old drove a superb final to maintain his position and take a hugely popular second place.  A driver who is no stranger to the World Championship stage, Brazil’s Flavio Elias would turn around a day that started off in the worst way possible when he was taken out of his Semi by another driver in pit lane while in a bump up position.  Having to go through the Last Chance Final, the WIRC driver won that to line up as the 11th car in the final and through all the drama found himself finally achieving a World Championship podium finish, a recovering Catanzani just 3-seconds back when they crossed the line.

While somewhat muted after his Electric GT Championship win, given the classes small entry, it was contrasting raw emotion for Mazzeo on taking the nitro title win.  Joining Toni Gruber and Joern Neumann as champions of the category, asked how it felt to become a double World Champion in the space of 24-hours, the super friendly Italian replied, ‘It’s incredible, I don’t think I realise yet what has just happened.’  He continued, ‘Today was a special day.  I was not stressed, I was really calm, and I was really confident in the work of Giovanni, Marco and my father back home, and I think we deserve this title.  I followed this dream from when I was young.  I was scared to make this long distance from my home but I did it to realise my dream and what I suggest to everybody if you are scared of something you need to fight it so you can realise you dreams.’  On his title win race, which looked near perfect from the outside, Mazzeo explain, ‘we lost almost 1-lap.  In the pit lane two times we had problems with the body, and I also lost 5-seconds with a crash with a lapping car but from the beginning I saw I had the speed.  When I see Andrea flame out, and I am really sorry for Andrea but he will be the future of this sport and will be a champion for sure, but when I see his car stopped I said “today can be the day”.  After that I just managed the car to the end and said to Giovanni when there was 2-minutes remaining we had won but before the last lap at the end of the straight I lose the rear and we broke the wheel and we arrive at the finish with a broken wheel, for this my last lap was 25-seconds.’  While many of his rivals had engine issues, the long time Gimar driver said, ‘we choose not the power, we chose to be safe and with the decision to risk or not I prefer to be safe because I was fast so I didn’t want to go faster.  I know this kind of final is very long, I had done them many times and I lose many times, so the choice was perfect.  The car was really perfect, everything worked good, the fuel was amazing, the tyres were perfect – that’s a dream.’

Reacting to his second place, Lopez said the biggest stress of the race for him was traffic, saying he had to deal with it a lot.  Asked how his race had panned out, the Puerto Rican driver replied, ‘All the time was OK, no flame out, the only issues was in the final 10-minutes one tyre exploded which we had to change.  With the one new tyre I put more steering on my radio but once the tyre warmed up it as all OK.’  With the Sweep controlled tyre coming in for much phrase for its performance at these championships, he added, ‘I don’t know why we had this failure with the tyre because for me they are a good tyre and I like them a lot.  Maybe it was just the 1-hour final.’  Qualifying sixth overall to line-up on pole for the Semi B Final, which he went on to win in the fastest time of both Semis putting him fifth on the starting grid, Lopez said while this is his first World Championships it is not his first time to race with the Italian.  Last year he travelled to Italy to take part in a round of their National GT Championship, the standard one of the best in the World as highlight here in Santiago, adding he ‘wasn’t surprised’ by their speed here and that he ‘needs to go race with them more in future’.

Getting close to a podium with fourth at the 1:8 Onroad World Championships in Brazil back in 2015, a decade on Elias was delighted to finally secure a Worlds podium finish.  After his dramas in the Semi, the Main Final started out looking like it might go the same way.  From last in the grid, a good start would move him up to fifth briefly before he was flipped over after contact from another car which put him back in last place.  With the pit lane closed for the first 7-minutes of the race, he would then run out of fuel after six & a half minutes however by the time his car was recovered and restarted, pit lane was open and he did suffer any penalty.  He said after that, pitting between 6 and 6:15, that the rest of the race was fine and he could climb back up the order and capitalise on the issues of other drivers.  Elias will return to track in a month and a half’s time when it is the turn of the 1:8 Onroad class to decide its next World Champion at the impressive CACH facility.

An understandably dejected Catanzani summed up the outcome of looked like a promising championship as ‘disappointing’.  Making a name for himself on his Worlds debut two years ago in Sydney, the 20-year had an impressive Day 1 of qualifying securing the TQ honours with three consecutive TQ runs ask about his final he explained, ‘We flamed out at 4 or 5 minutes for no reason, I don’t know why.  Then we restart, the race was long so we continue to race but we flamed out another time in the pit stop so we changed glow plug.’  He continued, ‘we also broke a wheel so we had to change tyres so maybe without his a podium was still possible.  The car was feeling strange and I thought the car was broken but when we checked it it was the wheel.’  With the fastest lap of the final, asked about the chance of having another go at Worlds success in Chile at the 1:8 Onroad World Championship, which start at the end of November, he said he still needs to discuss his participation with Serpent.

Catanzani is GT Worlds Top Qualifier as sterling Mazzeo effort just comes up short

Serpent’s Andrea Catanzani is the Top Qualifier at the IFMAR 1:8 GT World Championships in Chile, qualifying coming to thrilling climax at the Club de Aeromodelos de Chile track after a sterling effort in the final qualifier by Raptor’s Alessio Mazzeo.  After taking three of yesterday’s four qualifying rounds, Catanzani held the overnight TQ from Q1 winner Mazzeo who needed to TQ today’s two remaining rounds to deny his fellow Italian pole position for Friday’s 1-hour final.  Rising to the challenge by ticking the first box and topping Q5, the 33-year now needed to not only TQ the sixth & final qualifier but also to better Catanzani’s Q4 time.  With engine his sponsor Gimar fitting a new engine for Q6, Mazzeo earlier saying they had nothing to lose, he put together a brilliant drive and as the 7-minutes started to come to a close it looked like he was about to pull off the impressive feat, his projected time just ahead of Catanzani’s best.  It wasn’t to be however, Mazzeo’s engine going lean right at the end and losing power, costing vital 1/10ths of a second.  Still taking the TQ for the round and forcing the tiebreaker, unfortunately he was 6/10ths of second short with Catanzani, who has struggled today, securing the honour of Top Qualifier for the 3rd running of the GT World Championships 2-years on from when he announced the arrival of his talent on international stage at the GT Worlds in Sydney.  Behind the fight for the TQ there was also a battle for the order of the other two direct spots in the final, Super Pole no longer a thing.  It would be Natanaele Senesi who got the better of Alex D’Angelo concluding qualifying with his fastest run that gave him a P2.  With it an all Italian Top 4, best of the rest at the end of qualifying in Santiago would be Brazilian WIRC driver Elias Flavio who will lead away one of the Semi Finals while Raptor driver Carli Lopez from Puerto Rico starts on pole in the other Semi.

Not overly joyed by his TQ given it was clear he struggled on Day 2 of qualifying, Catanzani said, ‘For sure I am happy about the TQ but yes I am not super happy about the car so we have to think about what change we need to make.’  The 20-year-old continued, ‘We tried a different engine in the last quali but we started quite a bit lean so we had to pit to tune it, so then the qualifying was finished for us.  We continued so we could try the car as we changed something but it was not right so we will go back when we rebuild the car for tomorrow.’  Asked about car set-up for the longer final, he said, ‘its the same set-up that you use in the quali, you can us it in the final because there is no problem with tyre wear this race.’   On any potential gains in fuel strategy he said, ‘I think it is better to be safe because the race is so long. So here in these conditions it’s more easy because there is not so much consumption, so the strategy will be easy as you don’t have to change tyres.’

Understandably deflated having got so close to snatching the TQ from Catanzani, Mazzeo said, ‘It was super windy and the track was slower but I pushed harder and then bad luck in the last three laps because my engine became too lean and I lose power.  So I lose the time to TQ.’  The friendly Italian continued, ‘Congrats to Andrea, Roberto and Marco because they deserve to be in this place and I am happy for him.’ While he may have lost the TQ battle, the former Nitro Touring Car World Championship podium finisher is game on for the final.  Looking to the 1-hour encounter which due to bad weather concerns will run a day earlier (Friday) than originally scheduled he said, ‘for sure tomorrow we have to follow our dream, we will do it.’  On making any changes for the longer race he replied, ‘Nothing, just clean it with the air.  There is no strategy, just push, it’s like a quali but just 1-hour long.’

Probably the happiest driver at the end of qualifying,  Senesi summed up his P3 by saying, ‘At the end I am super happy because our goal is achieved, it was to be in the Top 4 so we are straight into the final.’  He continued, ‘The first two were faster, we already knew that but I think the strategy we had with the tyres was good so just one set up until the fifth round a new set for the sixth which allowed us to do P2.  The car was super good, we ran 21.4, Alessio was 21.3, just a tenth off so I think for the long final we can have a good balance and I am confident for the race.  Planning to just refresh the oils in his car, he said ‘compared to Australia where we had super high tyre wear so everybody was complaining about changing, here we are not going to make the tyre change because they last a lot and also on used tyres during the run they are pretty consistent.  The only point in my opinion would be to not push to hard to stay at the top because then they go out of temperature and the car starts to get loose.’  Very happy with his Gimar engine, he added, ‘I know behind me Alex is struggling with run time, Alessio and Andrea are struggling in some cases but I can do one extra lap so I am going to push as much as possible at the beginning.’

Reacting to his P4 and direct progression to the final, 2023 Top Qualifier D’Angelo said, ‘this was always the focus so I am happy, of course you always want to start ahead but in a 1-hour final if you start first or last it’s the same.’  He continued, ‘Today we had nothing to lose so we used the last two rounds to try something different with the set-up.  What we tried didn’t work good but we know how the car works with yesterday’s set-up so we can go for that.  In the practice tomorrow we might try something else’.  Asked about the final he said, ‘the strategy is going to be the same for everyone, the tyre wear is good so you can run 1-hour with no change unless of course your damage a rim or something.’  One area of caution he does have is regarding the engines saying, ‘to make the engine work for 1-hour will be hard because the straight is long and the grip now is high so the engine struggles.  For 1-hour it will be tough on the engine.’
