An aerobatic plane … not named

·         34” thick (18%) symmetrical airfoil (E 479), aluminium channel spar, coloured tape covered

·         Coro fuse with detachable canopy for access to electronics

·         900KV, 10X4.7 prop, 3S

·         Ailerons, rudder, elevator, throttle

Abhiroop (my son) with the aircraft

Very responsive in all three axis… good roll rate…. The rudder area was increased later on to enable knife edge.  Glides well for a stunter. … has good stall characteristics (adequate indications by wagging of wings) .. a good aerobatic  aircraft.. 

   

Shock Flyer
Own Shock flyer design made out of depron. This aircraft has two CF strips glued to either side of wing as spar (very light and rigid (very effective as it subjects the CF to tension on flexing). Also strings have been used to prevent flexing of the fuse and wings
Span 32"
AUW ; 360gms
1300 KV, 8X4.8 prop, 25amp ESC, 3S 800Mah

A good flyer. A little more power/less weight would make is fantastic.  Also I realized that I needed some more fuselage area for it to hold altitude during knife edges


Shocky

This is again a own design, made out of lighter thermocole.
Span 30"
AUW ; 240 gms
1300KV, 8X4.8 prop, 20 amp ESC, 2S 800 mah

She flies beautifully... due to the low wing loading can fly very slow. Hovers with very less inputs at 75% power. .. excellent knife edges, in fact can climb while in knife edge... the long tail arm makes maneuvers smooth and precise.
That is my son Abhiroop, ..  does  maneuvers like hover, knife edge with ease.. a much better pilot than me. he now tests out my new builds

Micro ShockFlyer

A mirco flyer built of foam and covered with clear tape.
Span - 16"
AUW - 95 gms
2300KV, 5X3 prop, 2S 100mah, 12 amp esc

 Requires constant inputs to keep her in air,.. agile and responsive. Looses altitude rapidly during knife edges and tip stalls abruptly at low speeds.. the TX  gives a perspective of her size
