Chassis Focus – Spencer Rivkin

Sat-RivkinB5mCE-9

Chassis: Team Associated B5M CE
Motor: Reedy 7.5T
ESC: Reedy Blackbox 410R
Batteries: Reedy 5300 Shorty
Radio/Servo: Airtronics/Reedy
Body – JConcepts Warrior

Remarks – Current World Champion Spencer Rivkin is running the new Associated B5M CE with a number of JConcepts optionals installed. Coming here with his base dirt track setup he has made only a few small adjustments including changing from the JConcepts S2 body to the Warrior which he feels has a little better steering. He is also using the new JConcepts Stabilizer wing that he says gives the car a lot more grip and as the name suggests is very stable. In terms of tires he is finding that his gold compound Dirt Webs are working better as they wear and in terms of preparation he is removing the outside row of lugs of the rear tires to give more surface area which in turn gives more rear grip.

Cavalieri takes first qualifier at JConcepts Finals

Cavalieri takes first qualifier at JConcepts Finals

Ryan Cavalieri has TQ’d the opening round of 2WD Mod Buggy Qualifying at the JConcepts Indoor National Series Finals in Omaha.  Racing for the first time on the HobbyTown USA Hobby Plex indoor track, the Associated driver was the only one to run 16-laps to top the times from practice top seed & last year’s winner Jared Tebo.  9/10th back on Tebo, World Champion Spencer Rivkin would complete the Top 3 ahead of Ryan Maifield, the TLR driver clearly unhappy with his opening performance.

LRSat-RCAct-2

Second fastest in practice yesterday, Cavalieri said ‘I just drove a little better than last night. The car had the same speed but I was a little more awake today’.  Starting behind Tebo but managing to get passed his rival early on, he said once in front his focus was to ‘maintain it (the TQ pace) and do nothing stupid’ adding ‘traffic in front was (his) biggest worry’.  While he felt the track was a little drier today he will leave his Orion powered B5M unchanged for Q2.

LRSat-TeboSatnd

‘Pretty good’ was how Tebo summed up his Q1 performance.  Suffering a couple of mistakes, one costly one coming through traffic near the end which required him to be marshalled, the factory Kyosho driver said ‘I’m having a hard time being really consistent in spots (of the track)’.  He added ‘the car felt good but its missing a little something’ and he will ‘try a couple of things for the next one’.

LRSat-RivkinAct-4

After catching the piping on his opening two laps, Rivkin said he needs to drive a little more conservative at the start of Q2.  The 17-year-old said after his untidy start, he was able to catch the leaders and setting the fastest lap of the race he said ‘if you take away mistakes I would have been really close with them’.  Happy with his Reedy powered B5M he will leave it unchanged for Q2.

BTWhip

Fifth fastest, having struggled in seeding practice leaving him to run in the second fastest heat, Brent Thielke described his result as ‘not too bad’.  Making a number of changes to his B5M, the Team Associated Team Manager said ‘in the warm-up it didn’t feel that good’ and so he took it easy over the 5-minutes but ‘for the heat (he’d) take it’.  Feeling his tyres were ‘too squirmy’ for Q2 he will run a different set of JConcepts Dirt Webs feeling his current set was possibly over sauced.

LRSat-Larsen

Completing the Top 6, Taylor Larsen said he ‘wasn’t expecting it’.  The 17-year-old TLR driver said he ‘didn’t think the consistency was going to be there’ but his 22 3.0 felt really good adding he was ‘not sure if the track had come to the car’.  Planning to leave the car as is for Q2 he said the only thing he would be doing different would be to ‘drive a little harder’.

Tebo tops seeding at JConcepts Final

LRFri-TeboAct

Jared Tebo has topped seeding at the JConcepts Indoor National Series Finals in Omaha, Nebraska. In the short 3-minute single seeding round, the Kyosho driver set the fastest three consecutive laps around the Hobby Plex track to top the 2WD Mod Buggy times from Ryan Cavalieri who was the only other driver to do a 59-second time. Running a time of 60.039, half a second off Tebo’s pace, Ryan Maifield completed the Top 3 with World Champion Spencer Rivkin fourth a further 3/10ths off.

LRFri-Tebo

Winner of the event last year, Tebo was happy to open official proceedings at the top of the time sheets. Running the same prototype chassis on his RB6 as he used to TQ the World Championships as well as JTP shock towers, the former World Champion said ‘once I got tyres sorted my car was really good’. Running AKA clay compound Chain Link tyres all round he said ‘I drove a little better too’ feeling he was now driving a cleaner line through the sweeper at the end of the straight. Also setting the fastest single lap of the seeding round, he said all he would be doing for Q1 tomorrow would be to ‘clean tyres and sauce them up’.

LRFri-CavName

‘It was good’ was Cavalieri’s response when asked how the seeding run had gone. The Team Associated driver, who pretty much matched Tebo’s fastest lap with a 19.769 compared to 19.744, added ‘its very close, we have the same speed’. Running the same tyre as Tebo, he said his B5M had ‘tons of traction’ and for the seeding run the ‘track felt good’. With the car ‘really good’ the reigning US National Champion plans to leave everything as is for the first qualifier tomorrow.

LRFri-MaifieldAct

Making his dirt race debut with the new TLR22 3.0, Maifield said his first few laps were perfect but as his lap times came down traffic prevented him from bettering his 3-consecutive lap pace. Running JConcepts Dirt Webs on his car, the reigning series champion said it felt easy to drive and he could still do fast laps predicting that over a 5-minute run and with less traffic to deal with he is ‘in it for the win’. Adding ‘all (drivers are) very close’, he said is was going to be down to which driver made the least mistakes and could get in the greatest number of 19-second laps.

LRFri-TeamJC

Having issues with traffic, an attempt to jump over one backmarker not working out, Rivkin said his ‘car was good’ and he had ‘good grip’. The 17-year-old added he ‘couldn’t have asked for more’ in terms of the car and fourth was ‘OK’ as it was ‘just seeding’.

LRFri-DerekWood

Behind the factory Associated driver, local racer Derek Wood posted the fifth fastest time. The Kyosho driver said the run ‘started off a little rough’ but once he got clear of traffic and didn’t over drive he managed to get 3-good laps in. Having started out the day with no front wing on his RB6 he said fitting one improved steering in particular allowing him to carry more speed through the sweeper.

LRFri-HorneAct-1

Completing the Top 6 for the 2WD seeding was Austin Horne. Describing the track as a ‘really fun layout’, the 15-year-old said he has done little to his Associated B5M over the day with tyre prep being the biggest thing they worked on. Competing in the 60 entry 2WD Mod buggy class against his brother and his father, he said with the car and his JConcepts Dirt Webs tyres working well his focus for Q1 is to ‘just drive it’.

LRFri-Cav

In 4WD Mod Buggy, it would be Cavalieri who would top the seeding, 3/10th up on Maifield and Tebo. Again Rivkin would end up fourth ahead of fellow Team Associated teenager Damion Borkowicz fifth with Nick Gibson completing the Top 6.

Tyre prep order of day in practice at JConcepts Finals

LRFri-TirePrep

Tyres are the order of proceedings on the opening day of the JConcepts Indoor National Series Finals at HobbyTown USA Hobby Plex in Omaha, Nebraska.  The fifth & final stop on the JConcepts INS calendar, the series’ third year to visit the impressive Hobby Plex facility has attracted a high quality driver line up among the 260 plus entries with all using practice to get their tyres down to the right thread depth in preparation for qualifying.

LRFri-Spencer

As the schedule switched over to a round of seeding practice new World Champion Spencer Rivkin, who is racing 2WD & 4WD Buggy and Mod Truck, said things were going ‘so far so good’.  Content with the performance of all his Associated cars, the 17-year-old said he was ‘just getting tyres dialled in for qualifying’.  Running JConcepts gold compound Dirt Webs with Dirt-Tech inserts on 2.2 rims, he said the 4WD needed the most work ahead of qualifying but added that was down to the tyres not yet having reached their optimum point with the Reedy powered B44.3 improving with each run on the same set of tyres.  Describing the track layout as ‘awesome’, the Arizona driver added it was ‘challenging’ and would ‘show the men from the boys’.

LRFri-CavAct-1

Although he did the National Championship double here in 2009, when the track was outdoor, this is Ryan Cavalieri’s first time to race on Hobby Plex’s indoor track which was built in 2011.  The Associated driver said the height of the driver stand was ‘challenging’ but in terms of his cars ‘everything was going good so far’ with ‘everything dialled’.  Racing 2WD Short Course as his third class this weekend, the multiple World Champion said getting his AKA tyres prepared was the biggest focus of the day adding ‘I haven’t touched a whole lot’ on the cars as they have been ‘all in the ball park’ from the first practice.  The only adjustments being a rear spring change on his B5M Champions Edition and going to a heavier oil in the rear of his B44.3.

LRFri-TeboAct-1

Winner of the two big classes here last year, Jared Tebo said ‘all my cars are pretty good and I have just been working on tyres’.  The Kyosho driver said matching the tyres so that the front and rear have the same grip level, joking ‘I hope once I get them right that they don’t wear too much’. Asked about the level of wear the AKA driver replied ‘Its hard to tell as I have been grinding them down (for each run)’.  Also racing in Short Course he said his tyre for this still needs a bit of work but for 2WD & 4WD Buggy he can now work on getting a second set ready. Asked about his pace he said with the level of traffic on the track its hard to tell where everyone is at but he declared himself ‘pretty happy’.

LRFri-MaifieldTrack

Making his dirt race debut with Team Losi Racing’s new 22 3.0, Ryan Maifield said practice was going ‘really good’.  The 2014 JConcepts INS Champion said his focus has been getting used to his new 2WD and trying different set-ups to see how it reacts, adding it ‘feels really good already’.  Only running buggy this weekend, in 4WD he said he was running ‘standard stuff’ on his TLR22-4 describing it as ‘easy to drive’.  Apart from learning about his 2WD he said ‘getting tyres  prepped’ was the main order of the day.

Chassis Focus – Ryan Maifield

Fri-Maifield223-10

Chassis: TLR 22 3.0
Motor: Orion 7.5T
ESC: Orion Vortex R10.1
Batteries: Orion XS4000
Radio/Servo: Airtronics/Spektrum
Body – JConcepts S2

Remarks – Current JConcepts Indoor National Series Champion Ryan Maifield is making his race debut with the production version of the TLR 22 3.0 that he helped to develop. The new car which was announced last month has a new 3 gear transmission, as well as the possibility to use the more standard 4 gear configuration, and a new chassis plate to accommodate the sideways mounted battery which all allows a much different weight bias to the previous car. Other new features include updated front A-arms that allow the shock position to be changed without the need for the shock to be adjusted and also sport the new optional outer arm pin position which along with the new front caster blocks allow for variable length arm adjustment. Comparing this to its predecessor he says it now corners better, is faster as well as being easier to drive. Other new items on the car are the final production version of the new S2 body shell from JConcepts which made its debut at the Worlds in Japan and a new Stabilizer rear wing, but more information on those items later.
