scratch building a BELLANCA 28-92 TRIMOTOR!!!


well was flipping threw pages of a old 97 RCM book and came across this and said i got to build one of them!!! the original plans were for a 56in.WS running 3 speed 400's on 8 standard 1700mah cells, so what i did was took the page to kinkos and had them blow up to were i got a 42in.WS with a 25in. fuse length, think i"ll try 3 280's or 300's spinning zagi props with 10cp1300's(still want the speed) other then down sizing all the material and tracing all the parts things are going quite well, isnt the 1930's vintage racers a thing of beauty!! heres some pics, any help on the power train is apprieciated.

I may have to get back onto mine soon! Mine will be the standard 400 size though, I cant imagine working with so many parts that are that much smaller Yours really looks nice and keep up with the photos, I like to keep motivated

tri motor


okay, almost done covering+weighed everything, with 3 sp-380's and all other support equipment less the batt my weight was 28 oz. now if i use the 10cp-1300 then my auw will be 41oz.!!! how does that sound? do you think i'll be alright? my kc edf f-18 came in at 39.05oz. and that was with 1 motor, but i had to bungee launch that! each motor weighs 3oz. a piece, so if i did a single i could lose 6oz., but then i defeated my purpose by building a tri, post finish pics later
