a few quick questions from a newcomer

[griemar]

I just got a RC10 GT2RS stadium truck and have spent the past few hours breaking it in. I personally am truly impressed with this truck. But here are a few question I have about it.

1) I broke in the engine with Traxxas Top Fuel 10%. I ran this through for about 8 tanks. From the first tank all the way through the 8th tank, performance was "to be desired". I then moved up to Traxxas Top Fuel 33%. What a HUGE difference! A few tweaks here and there and now the truck seems to be coming into it's prime. Now for the question, is running 33% OK for this truck? I have a AE .15 engine and I seen several posts elsewhere that say not to go beyond 20%.

2) 85% to 90% of the area here is road, not many places to run in the dirt. Because of this, I am having issues with being able to make high speed turns. The front end just slides. Now I know the stock tires are not that great, but is there a way i can dial it in for now that I'll get better turning at high speeds?

Thanks in advance for any help.

33% is considered a race blend. it will lower the life of the motor and will tend to run hot. it does have a little more zip tho.. for sure. but thats the price you pay. i had simular situations with my jato as far as the front end "push" goes. i was able to correct it a little bit but not much. i put stabilzer bars all the way around. stiffer springs and thicker shock silocone. i dropped it down as low as it would go as well as kicking out the front camber a couple of degree's. my best resoults came from tires and tire traction compound. it still pushed some with on-power stearing. thats a resoult of the front chassis kick up(caster).

Head clearance and compression determine what nitro percentage you need. Follow the manufactuer's suggestion, although some do not give a nitro percentage reccomendation.
General rule is no more than 20% nitro in a small block engine.
Although if it runs good, don't sweat it. Keep running it as long as it tunes out good with acceptable temps.

guess I'll be looking into a decent temp gun tomorrow, along with better tires and a few spare paerts. I tried the "boil" test on top of the engine (drop of water, time how long it takes to boil away) and so far it seems to be running cool enough. Takes about 8-10 seconds to boil dry. But I dont exactly trust this method, would rather be sure with a temp gauge.

Any ideas of the optimal temp for that engine? Just in case I didnt say, it's a AE .15X.

Thanks again in advance.

Most any engine is suppose to run between 220*to 260*
