New Team CRC Gen-XL
#1186
[QUOTE=Monkeys punk;9733869]Really depends on track size for rollout but for a medium sized track I was rolling out about 88mm when running boosted 17.5. It was one of the fastest cars on the track but motor soon gets hot so need to watch your temps. I would get the smallest spur you can find and that will make pinion choice easier. I found a 48dp 58T spur and was running 46mm foams with a 35 pinion.
thanks for the info. i run in small track, 40'x30' is that mean higher rollout is possible in smaller tracks?
where can you find 58t spur and what is 48dp?

My typical starting point for boosted 17.5 is a 3.2" rollout (90' x 40' track) and adjust boost and turbo depending on motor temp.
I use CRC magenta fronts and magenta rears.
CRC/Power push battery with a Trinity D3 based tuned motor by Team Scream.
I haven't tried the new spurs yet, still running the same diff from last season..lol..

64 pitch, smaller teeth on the spur, more adjustability for rollout. Indoor/Outdoor, but better chance of stripping teeth outdoors.
The shorter the track the lower the rollout, but not drastically lower. If you're at 3.0" now, go down to 2.75" and then temp after 5 minutes. After that its all about how the car feels to you.

I was running 48dp as its the only pitch I could find a spur that small. I now run 64 but have stripped a few spurs since switching. I am in the uk so use Action Model Centre. They are great for 12th bits and I would imagine they can ship overseas if your having trouble finding anything locally.

i've been told adding a washer or spring washer between motor screw and motor pod can reduce chance stripping gears

When I torque down my motor screws, I put a nice thick super soft bronze or aluminum washer between the screw and the motor plate, torque it (I use long steel screws with the big metric hex that fully engage in the threads in the motor can) until I just see it start to give, never gets knocked out of mesh, haven't stripped the motor can yet... granted, I don't take my motor out that much.

Hey guys
Has anyone tried the Speedmerchant GenXL kit ?? there was 2 assosiated cars at the track on sunday running the inline battery conversion and WOW they change direction quick
Thanks Phil

I only run 17.5 boosted, and 13.5 boosted, so Mod may exhibit different tendencies that I haven't experienced.

Does anyone have any photos of the best way to mount a speedo? I have a LRP SXX Stock Spec and really cant decide what way would work the best?

I'm new to the Gen XL family and am getting my car ready for my first 1/12th scale race in a week or so.
I'm placing the electronics that can be moved around (Smartboost, Tekin RS, SR3500 and MRT PTX). No matter where I put the electronics, the best left-right weight balance I can get is a 25 g difference between the left and right wheels (left side being heavier).
Is the 25 g difference in lateral weight distribution big enough that it's anything to worry about? If so, I'm not sure how to achieve perfect lateral balance because the heaviest components (motor and battery) can't be moved laterally.
After fiddling with electronics placement for about two hours now, I'm beginning to think my 25 g difference in lateral balance is as close as I'm going to get. I'm tempted to servo-tape the stuff in the location that gives me the best (although not perfect) lateral balance, go drive the race and see how the car handles.
Thoughts?

Is that the whole car or minus the pod. It's the main chassis plate that needs to be balanced so try it after removing the pod. I can get a Tekin RS, PTX, JR Z3650, RCDynamics booster and Sanwa 451R balanced perfectly. Also remember to do it with a cell in too as their weight is not even from side to side.

Can anyone let me know the changes in handling I will get without the long arm or top brace installed (basically kit). I am looking for a little more steering on a lowish grip carpet.

Just also found this, maybe a new chassis soon ?http://www.rc50.com/modules.php?name...bum=67&pos=297
