24" Speedwing Dart


Done

She was too nose heavy, with a lot of torque roll......no damage, so I changed the motor out to a 3530 1200kV (had to build some standoffs)....will try again tomorrow

Flew this thing yesterday...even at 20% throws and 50% expo she was like trying to fly an epileptic monkey on meth

Sure I want her to be fast, but I can't achieve what my friend did with a 3000kV prop drive

Here are the drawings I worked from....fuse sides and fin are 3/16, ribs and fuse T&B are 1/8, LE is 3/8" SQ, and I used some heavy aileron stock for the elevons. Spars are 0.156 sq CF......also added some 3/8 triangle stock so I could round the nose...Basically this thing was made from all the leftovers from previous builds.....Airfoil is a Wortmann FX 76-120.....

I didn't annotate the drawings......this is a whimsy prototype...I don't even know if it'll fly

Spec's: 3542 1200kv motor, 65 amp ESC, 2300 40C 4S battery, 8x4 APC-E prop, ES-3104 metal gear servos, 2 1/2" spinner, Lemon Featherlight 6 channel DSMX/DSM2 receiver.....

Sorry if you felt offended, it was not my intention and if I did I apologise. I was just trying to suggest combinations to achieve higher speeds.
