GOod idea, (This is how my name is SHoddyCOmp with the extra caps, i do those typos all the time :roll I wouldnt run more than 20% in a brand spankin new engine like you've got there. I dont know what kind of fuel you use but blue thunder is most popular but I prefer wildcat fuels (100% synthetic vs castor oil). One more word of advice, especially if you're going to be running on asphalt and jumping on hard surfaces land as flat as possible, those plastic shocks wont hold up very long. The caps will blow off without any trouble if you end up with a one-corner landing. Remember gas pitches it up and brake brings the nose down. Actually though the first time i blew my caps off was just a high speed turn and braking which cartwheeled the truck. Pop. Ive heard tips about using small hose clamps around the caps of the shocks tightened down pretty good so it would grip the body of the shock better to prevent blow outs a little more. I havent tried that myself since i bought some AE aluminum shocks but it sounds like a logical idea.
