After my disaster of f15 due to very high wing loading and loss of adequate thrust, dint lose hope and built new f18.
Its 32inches in ws and 51inch in length. Dint take any pics during construction, as I did everything in a hurry.
Maiden was a success.
This is what I felt about this design. All electronics are easily accessible. Motor mounted in such a way that a 6x4 prop doesnt touch the ground. Has complete clearance for the prop as intakes are made large enough to provide good clearance for the prop. Most of the pusher designs I have seen have props touch the ground during landing, and motor mount usually collapses in long run. In all the best design I have built so far. No trims were needed even during a maiden.
The design uses a kf2 and the design handled the wind very good. Not at all affected by the wind. The rolls were very fast. Very stable in air.
This was the setup used.
Motor : NTM 3536, 1800kv motor.
Prop: EMP 6x4
AUW: 1kg
Thrust: 1.1kg
Battery: Nanotech 2200mah 4S
