She flies !

CF 105 Ver 3 Maiden (2 min 56 sec)

A few changes from Version 2.0......maiden will probably be Thursday

30" WS x 40" OAL x 46 oz AUW
3/16" Elmer's board
KFM-2 airfoil
83% thrust cone (hybrid nacelle/fan mount)
(2) 70 mm 5-bladed Dynam fans with 3000 kV motors
(2) 50 amp ESC's
(2) TowerPro MG 90 S servos
(1) Lemon 6-channel Featherlite receiver
(1) 3700 mah 40C 4s battery

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.

Got bored and built this today

2217-6 1250 kV 8x6 2200 mah 3s 40A ESC

real easy to fly, plenty of power, added a bit more rudder throw, and she'll knife edge..........if you notice, you only hear three clicks of trim..flew her all morning
