I'll use 2 battery packs Nicad ( 2400 & probably 1000 Mamps) (Flat shape pack for the big one, bump for the smaller if go into the nose cone or flat if go on top of nose gear area.....I guess.)

The big one goes under the rear servo tray, right behind the front former.
The small one....find a way to mounted in the nose cone of right above the nose gear retract area.

And of course...the ECU batt at the nose cone too.

For the nose gear door actuartor....I did some real head scratching trying to fin a systems works and also with a nice design look....I was complex to do....but I worth the effor [&:]
These picture does not show up to much.....but I'll take a few more pictures this fternoon for you.


As per the cilinder location for the aft nose door....you are lucky I found an old picture....: - ). If I'm remeber correctly ( ???) use a cilinder shorter then 1".... to avoid over traveling issue. But anyway I'm sure you will know how to deal if so.

Good luck.-
