Dornier Do.335 research questions....
I have just got a massively huge urge to scratchbuild a foam/balsa model to run on 2 x Mega Motors, a 16/15/5 in the nose,and a 16/15/5 in the rear,running 2 x 2.5:1 gearboxes,running from a common pack of 16 cells.Can anyone suggest prop sizes please? I'd like to possibly power it with Li Poly cells,so any suggestions there too will be greatly appreciated.2 packs of E Tech. 3s2p 1200's sound ok,or are there other alternatives?
I have an old set of Rhom Air retracts I'd like to fit, but with some lightening performed on them first.
I plan to build it around 52" span,and want to build a foam,(hollowed) fuse with glass skin,and balsa built up wings/tail parts.
Firstly, does anyone know of a source of fuse sections,I have some superb scale 6 views, but would be simpler if I could find some plans (any size) with built up fuselage sections on it.
I just love this aircraft,and have been fighting the urges, but are too overwhelming now to ignore!
Can anyone help please?
On the s400 Do 335 I built, it drew 22-24 amps on 10 cells, parrallel on 2x7.2 volt motors.
The front prop is 6x4, the rear is 5.5x4.5, but I plan on changing to 5x5, as I believe that the front motor is doing all the work.
The plane is 39in WS, 40 ounce AUW. 312 sq in, a little smaller than you intend.
Hopefully you can use some of the numbers along with Mark's formulas to give you a starting point.
I am interested in how you do, as I have been tempted to put Megas in mine.
I would probably use 16/15/6's in mine with 8 cells (a weight savings), 7x5 in front and 6x6 in back.
This may be a reason to build another..maybe to the two seater!
