Default Tiger Moth

I'm yust building my first park-flyer, which is Tiggie and I have some problems with it.

I prefer glow engines and so i don't have any knowledge abuot bateries Anybody knows how long can i stay in air with 7 1700mAh bateries, speed 400 engine with reductor (JETI i think) and plane with wing span of 850mm?

can i put in 2.5cm3 glow engine? (10mitutes in air arent enought, this is why i need some fuel)



BTW: which engine do you recommend (electric); speed 280 category or speed 400 or higher?


bye

Default Tiger Moth

D.H. 82
wingspan: 850mm
weight:430g
wing load: 18g/dm2

But I want to put in "400" electric engine and 7 1000mAh cells (or 2.5 glow engine)
With electric engine could I be up for about 15-20min, but there is one problem; wing load will be more than 25g/dm2


What do you think?
Bye
