Question
Large foamie.

I would like to build a large ultra-stick type foamy in the 55-60" span range. Has anyone done this before? And what motor would be best? I am thinking of using this motor.
Thanks

That motor would probably do a decent job with spirited sport flying performance if thenplane comes in less than 4 Lb. Perhaps 4s 3000 pack and a 11x7 prop?

I built one with a 4 foot X 1 foot chord wing and it came out about 28 ounces with a 2200 3s and would fly 8 to 10 mins on a pack. This plane also had a 2mm coroplast fuselage so it was extremely strong.

It flew well as the wing loading was extremely low but the plane would move along fast with a 10X7 apc prop. I used this motor: http://www.headsuprc.com/servlet/the...80-Plus/Detail

I am building a 60 inch high wing plane with the same wing area this plane had. Cutting the fuse down to a stick type would be easy.

I am thinking of going a little smaller, with a 50" wingspan and using this motor. I am hoping for a 40 oz flying weight. Would this work?
