I've had my R2 out for two race days now, and I like it!!
I was having some setup problems on the first day, trying to get it all dialed in. I was using Gravity type C tires which weren't giving me enough rear bite. I tried changing toe, roll centre, shock positions, droop, but no matter what the change I still had alot of over steer, mostly mid to exit. This car has a lot more steering than my previous touring car (S1/R1 hybrid) and because of the way I set up the ackerman, it's much much more responsive on centre. I had to put some expo in the controller and dial back the dual rates to make it a little easier to drive. I ended up breaking a left c-hub. So now bth C-hubs have been switched from the hard ones to the normal ones.
Day two I changed the rear roll centre and experimented with tires. I switched out the Gravity tires for Team Powers 26's. With no other setup changes, these tires gave me the exact opposite problem. I had ridiculous under steer on corner entry, especially at the end of the straight, and the rear was planted. From the TP's I put on a set of Sorex 28R with harder inserts. Again with no setup changes between tires, the car suddenly felt great! Almost neutral but with a touch of over steer occasionally, the car felt fast and predictable. These tires with the hard inserts were causing me to scrub alot of speed in the corners though, I had too much grip. I built a set of Sorex 28's with the standard blue insert and all my troubles disappeared! The car still felt like it was glued to the track but I wasn't losing speed in the corners. I should have known better and used Sorex from the start since this is what I ran on my other car. I managed to match my personal best 6 minute time, match my best lap time repeatedly through that heat, and even beat it twice! I even managed to take the B main to bump to the A!
I'm very impressed with this car. While the changes between the R1 and R2 seemed minor to me, they have clearly made the car better. The steering is more responsive, the car feels solid, predictable. This car allowed me to follow a much tighter line over my old car and made me feel more confident. Once I get used to the way it drives, I think I'll see a significant improvement in my lap times and consistancy.
I'll share my setup in the learnsetup.com app this week if anyone wants it. I put my starting setup in there and gave my thoughts on it after day one.

sounds good! did u try to screw and unscrew the upper deck of those optional holes?
the pole that between the steering and upper deck, it's make big different in screw/unscrew/ screw with a pin or remove that pole.

any more information or photos about the race?

Butler02

Oh ya, I forgot to mention that! I originally started with the brace on the steering and the screw in the centre of the rear brace. That didn't last long. I took them both out. On my previous car I only had one pin on either side of the lay shaft mount.

Just back from TITC and have some rest, we've good experience in TITC 2015, especially the 2 new options: Upper Deck Pivot Ball Floating System and the Floating Steering Conversion Kit, both were working really well in the high speed track like RC addict!

let's check out some photos,cheers

Anyone have a set of 4 R2 lower bulkheads they want to sell ? Spr-r2a133. Pm if so.

I'd say that is unlikely as r2 bulkheads not compatible with anything else.

Wish we had big tracks like this here vut I'm pleased to say my rsd chassis r2 is working super great on crc carpet.
Playing with some team xray guys this week and Getting close to a good setup for medium/ high grip 100x42

They will be mounted to a R2 chassis. I enjoy racing on our large track compared to our indoor small carpet track. We really get some good speed down the straight ! With the R2 I have everything I need to start bulding my R2 except the lower bulkheads. I may have saved half the cost of buying the kit but Spec R unfortunately has been a huge disappointment with there stocked parts. Im to the point of giving up on Spec R and going with a big name brand !

I recently started building an R2, only concern I have is the diffs... has anyone tried swapping them out with other brands yet?

I've had no issues with my diffs. For build tips you'll want to push the bearings in the rack through a plastic sandwich bag. Otherwise there is a decent amount of play with the bearing in the rack. I also drilled the shock caps and the shocks built easier. They all also had a more consistent feel between them. Lastly I switched the ball cups out to the Tamiya ones. They also had a lot of play and liked to pop off easily. It's a great car right out of the box with the stock set up, you should be pleased with it.

i run a 4.0 or 4.5 in my r2 quite often with all the timing indoors and out.. ive had no problems with reliability of my difs or any leaking.
i will say the R1/t3 dif is nicer and probably lighter. the gasket is much much much easier to do deal with than the oring of the hd dif. I replaced one of the sets of bearings with shock orings cause 4 bearings was kind of silly.

however, once you have the hd dif assembled and in the car. its absolutely trouble free.

I was a bit frustrated with my first day of racing this car. My rear diff leaked all over the chassis and made a big mess plus the diff just felt too tight (even after it was empty). It took me 4 tries before I finally got lucky with getting that annoying rubber o-ring diff seal to properly seat in place. I had to spend about 20 minutes stretching it out and eventually got it to stay in place with some green grease. I think the seal kept popping out of place and would bind with the planetary gears, but now there's no leak and diff is buttery smooth. All I can say is that I'm definitely NOT looking forward to rebuilding this diff anytime soon





As far as handling/performance goes, the car is a dream to drive and no regrets buying it.

It's actually a really good diff. Their diffs are used on many other chassis' also as Spec R has them available. This diff is much better than their earlier versions, believe it or not.

I ran my R2 for a season of practice and race without rebuilding it. It only started to seep at the end.
