The first time I tried to make this airplane fly didn't turn out like I wanted.......it could almost barely drag it's butt into the sky.....embarrassing to say the least....Version 1.0 had a single 70 mm fan....... Version 2.0 has (2) 70's that I moved outboard of the fuse.....AUW with a 3700 mah 4s is 48 oz....maiden tomorrow

Update: Got taken out by ingesting a dragonfly or two into the starboard fan...it exploded and Version 2.0 hit the ground hard.....broke her all to pieces. Got two good passes in over the field and was going for my camera, when a swarm of dragonflies descended on the runway....you can still see the bug juice on the inside of the fan housing.
