i run grape all the time. it has no adverse affects to the engine other than a permanent "flavored" smell to it. the indoor track i run at requires you to use it. small price to pay for the privelige of running nitro year round. it makes the exhaust fumes heavier so that they are easier to evacuate from the building.
I found that it kinda messes with performance in both of my engines. It makes them not as responsive and kinda slows em down. Then i use just straight fuel and it runs perfect. So i have 2 bottles of bubblegum and cherry sittin around now.
Yeah, I had about 1/2 gallon left and dropped off my truggy for him to mess with/charge Rx pack and he decided to put a "little" grape in it. I had already put more than enough cherry into the 1/2 gallon. Still have a few tanks of it left.........
A guy at the track started using it a few weeks ago. The back of his van smells like a case of Dad's Root Beer exploded in there.
If I'm correct, I believe there's even a nitro and oil content in it, so it won't thin the fuel.
Thats cool I diddnt know they made it for Rc,s. They have been making it for a while now for alcohol dragsters and my brother found some place you could add it to regular fuel He wanted to put it in his jeep. Do they make nitro flavored smell lol :jk:
