Well, I guess that I been having allot of input or advises, I appreciate all the guys that have put a little of knowledge, I decide to stick with the 10% nitro it's cheaper though, I have another question for you guys, I'm trying to decide which radio I will get, I have in mind on two radios, one is the JR R-1 and the other one is the Airtronics M8, so, if you guys know which is the best one let me know, remember I'm not looking for a cheap radio, I'm looking for a good radio, any advice on this one will be appreciated....Once Again.... Thanks!
