This is another electric conversion, but this time of the .40 size Great Planes Super Sportster Bipe from the 1980’s. This kit has been discontinued for quite some time and I was lucky enough to come across one on Ebay and I didn’t let it get away. This was my first large E-Convert (if you call .40 size “large”). It’s funny,… I used to think that .40 size was about the smallest you wanted to go and now it seems HUGE! Anyway, this was a rather difficult build. I won’t bore you with all the nitty gritty details (those are on the WattFlyer Blog HERE), but I had to add dihedral braces to the lower wing, cover up the nose where the engine is supposed to stick out , add as scoop, bigger wheels, interplane struts, and cover up all that exposed wire in the gear and struts. I also added lighting holes in the tail planes. I could (and should) have done more to lighten; especially in the rear half of the fuselage. It is ever so slightly tail heavy. I actually dyed the canopy that pink-ish color to match the color scheme. More Monokote, but it behaved itself this time. It is a good flyer and I did manage to shave an entire pound of the final weight at 4.5 pounds. It floats and floats on approach and will take you a bit by surprise. I have upgraded the battery from the 3S 3300mAH (11.1V) lipo to a 4S 4000mAH (14.7V) lipo. This should give me a bit more power and a little nose weight. I am currently waiting to iron out some power issues with the 4S batteries and will be using the Falcon to get it all straightened out. I’ll keep you apprised.
Specs are as follows:
