RE: ????? Topflight P-51 85" What's Yours Weight????
f18, make sure you put your battery, receiver and anything else that you can towards the up most front as much as possible, I'm using a 1800mha 4.8 Nicad battery for extra weight and I mounted it on the back side of the firewall wrapped in foam. Hey if you need weight better to use a bigger battery then lead (dead weight).
Post a couple pics of your radio compartment if you can, what about you cockpit is there alot weight in there? might have put on more than needed resin on tail feathers? did you paint yet? what stage are you at with the air frame? post a few pics for us, maybe other will help out also with some ideas.
As for the DA50 I believe thats pretty close in weight as the Moki 210? the 50 might be a little lighter? also make sure you have the correct balance point, also when you balanced the plane did you have everything as if you were going to fly it installed????
