3 items:
1) The new 5 cell nmh pack works fine so looks like a bad cell was the issue. Thanks all.
2) flooding: I mounted tank standard as instructions. I fule the plane with the tubing disconnected from the carb. (I will be adding a fueler with the cowl at later date. No big deal but I have to watch for lockups when starting. I posted since the reviewer had asked the question and was not getting answers.
3) performance of 91 surpass 2. 9 flights now. I am now at the stage were the plane will pull slowly out of a hover but I am still running rich. 15x6 prop. CAP232 of this list flys the same plane on the 91 sup 2 and his is fully broke in. It pulls out of a hover with autority. seems unlimited vertical. It is not an extreemly fast pullout, but is with great percision.

Looks like I too will need both down and right trust. I have to use down elevator and alot of right rudder to hold a hover or extended vertical line.
