Any remedies? The belts arent that stiff to cause much stress on the layshaft.
also happened to my teammate last night.
The main problem is that the spacers are too tight.try a little filing on the tube-like spacer for a bit so that there is a TINY bit of side-by-side play.

I have a question,On the 1.77 pulley's I have been told the only time you want to use them is on a big track(for stock)I tried them and the car was slower than it usually is(for some reason my xray is sloooow)and I'm in the ballpark on the gearing,belts are not to tight,I have the 3mm belt in the back,drivetrain is free,when I put the same motor/battery combo in a different car I'm one of the fast guys..again,I like the way the xray handles but where I race at it's stock and 19turn and my xray is really slow,and I guess my question is,am I missing something,maybe,or is the xray just slow in stock(I dont think so)

xxxkat-Are you sure that you are gearing accordingly to the track and now that you have switched to the low ratio pulleys.Maybe the motor that you have been using just isnt fast anymore.

When you run 0 anti-squat are you using holes 1 and 2 or holes 3 and 4. I was told by Ralph that you want to run 0 and use holes 3 and 4. Just curious as to what you prefer.

Also what compound arms were using on your Cleveland setup?

When or will the new bulkheads be available?

Thanks,

Crash-What Ralph told you to use is pretty close to what i use.I change it depending on track conditions.At Cleveland i used the short arms.I used medium front and hard rears.I think all the new products will be availible in the next month or so.

Alex,I switched the motor and battery pack to a different car(TC-3) the TC-3 was fast,put the the motor/battery combo back in the xray and it was once again slow,On the Xray with the 1.77 pulley set,using a monster stock on a med. track(tight turns/long straight)What final drive ratio should I use(just to get me in the ballpark)I know that every motor is different,but I'm just about to put this car back on the shelf and start winning again,right now I'm about 6/10 of a sec. slower per lap with my xray than I am with any of my other TC's...I really like the car but I like having a chance of winning also.

Default gearing

XXXkat,
I can say for Alex, we tinkered with my car to match his rollout at the USTC event held in Enfield, CT by RC Madness. The track was exactly what you described, tight infiled with a long straight. His rollout was, .87 something, something. I beleive he was runnig a 128 spur, tire size was 2.6. His car was hands down the fastest there, running the Epic Binary. You can do the math from there. That is all I can say for now. Alex, you did awesome this weekend, glad to see you and have a chance to hang out.

Alex,The track is 120 ft by 55ft asphalt,we run rubber tires(sorex 24's to 32's)The straight is aprox. 110 ft. and the rest of the track is turns with very short straights(maybe 10 to 15 ft. at the most)I have tried the epic binary stock,but as of yet have not found a good ratio for that motor,(tried to keep it in the 7.50 final ratio)I am running 48 pitch gears,Thanks for any help you can give.

I just got a T1r and my local hobby shop doesn't stock any parts for it. Could someone tell me what parts I should stock up on to get me through race weekends.

xxkat-I would start off with a 7.90-8.00 final drive ratio.Try that and let me know if it works.

Alien too-I would suggest that you pick up some 3 and 6 degree caster blocks,dogbones,dogbone blades,a arms,ect ect.They sell a c-hub suspension kit that brings everything you will need.

I'm thinking about buying the low ratio pully set for my Evo2 and have a question, can I use the one way layshaft or will I need the solid layshaft? How about the high performance belts, do they make a noticable difference (ie, worth trading up from good stock belts to)?

psbarger-I higly reccomend you to purchase the low ratio pulleys.You will notice that the car will accelerate harder everywhere.The same with the belts.They free the car up more,the same goes with the pulleys.As far as the layshaft one-way,i also suggest that you purchase the solid layshaft.Get rid of the layshaft one way.
