I don't like lipos in my nitro's or well this is my first gasser so. And you have to run a volt reg with the 123 batterys? I don't relly know what I am going to do. I know for sure I will have the 6 volt 2200mAh for the servos and the 4.8 2200 mAh for the CDI. I keep going back and forth on the battery share thing[sm=confused.gif] I could run it both ways and it would be fine I am sure of that. But I have seen so many planes go down just because of the battery and I have so much money in this plane. I am going with Hitech all the way aroung 645 on the rudder and some 625s and 475s and one 82mg for the throttle. I have been going back and forth on those too[sm=spinnyeyes.gif] there is so many diffrent kinds and MONEY that is the big thing too.
