And your sheet doesn't mention if you are unscrewing the bottom shock eyelets at all.
Why quit there - how about blue or yellow? Anything is an improvement over the long rears.

Default rtr reedy motor to hot

Guys i bought the rtr and from the start i noticed the motor was running to hot. I'm getting 170+ after 8-10 runs. That was with the stock 14/62 setup. I put an aluminum heat sink on and went to a 13/62. I can't get any lower and still make the doubles on my track, but the temps are still high. Is there a chance it may be turning to fast and I need to go up to reduce temps? I'm new to this but I know heat will kill a motor, so I would love to get this worked out. I don't mind going faster but can't go any lower than the 13. Thanks for your help.

How about a fan?



On second thought - do you have the stock slipper?

where are you topping out down the longest straight? I usually target the vehicle to top out towards the end of the longest straight within reason and adjust my gearing from there for how it feels around the rest of the track. Usually helps keep my temps in check.

And your sheet doesn't mention if you are unscrewing the bottom shock eyelets at all.
Shock ends: I normally run 2 turns out on the shock ends but when our track is wet and the bite comes up I will go down to 0 to 1 turn out depending on the layout. Right hardly any jumps and I am running slicks on wet clay so 0 turns out.

Front springs on the rear: Right now I like the greens on the rear with the stage 2 pistons. The white springs I felt had too much rebound with the stage 2's but was real good with standard 1.2 pistons. With your bigger jumps I would look at the whites because it does seem to help the truck jump more level.

This weekend I have a big two day race and will be testing shocks and springs so I will have a better opinion (for what its worth) after this weekend.

anyway, again nice truck all around. Bet you win a lot of races.
I've won a fair few... haha. No indoor tracks here in El Paso,SUCKS!!! I miss Tucson and running at Competition Hobbies.

O, and yeah, bad luck was all I could say... What pissed me off was that the guy laughed about it and thought it was funny. Cost me a pretty penny to fix everything.

It's all about having fun man. I could care less if I go out and finish 42nd out of 43 cars, as long as I'm having fun, I'm a winner. Good luck with whatever you chose to do man.

I am topping out about 3/4 down the straight. I do have the stock slipper but have a center diff on order. also do you guys cut holes in the chassis when you mount the fan there.

I went back to the track and put another pack thru it and it hit 210 and the esc was at 130. It seems hotter with the 13 than the 14. would the slipper slipping cause it heat this bad?
Thanks again guys for your help, I would rather not replace the motor in the first month.

If you are already hitting in the 200+ range I would think something on the motor could possibly be damaged ...

Sounds okay.

Yes, or mount it on top of the chassis facing down.

Yes, but it's easy to check. Check the slipper temp.

80 degrees difference between the motor and the speed control is not normal. Good luck.

what would be a normal difference between the esc and motor.
Thanks

I don't know - 20? When I ran my Novak 4.5 550, I never got it over 140, like ever.

The temperature difference between the esc and motor doesn't mean anything. The change in esc temperature can tell you if gearing up or down should be the way to go.
