flybyme,

I have a Big Stick 60 with an OS91FX on the nose in the stock position. I had to add 6oz of weight to the tail section to make it balance correctly. I flys just fine and the added weight doesn't seem to slow it down any. I have several ARF's and have had to add weight to them. I have a Seagull Zero that had to have a substantial amount of weight added to the nose to balance.

Cheers,
Andy
