Post by: rcpilotacro on January 27, 2017, 11:33:24 PM
Stribog is named after Slavic god of winds, spirit & air. Inspired by Jesse Davidson's Ryan Low Wing but looks? looks very different from it. Reduced wing thickness by 2%. Flies like it is a pylon racer. Flies using a ASP 52 2 stroke. 4 Std servos with nose wheel steer. Specs are as given

Length :        125cm
Breadth:        140cm
Weight:         3.2 kgs

Maiden

Take off, hardly any trim, Flies like it's on rails

Level flight  9/9

Inverted 9/9

KE  5/9 (max KE angle is about 70 deg bank)

Loop  9/9  (Butter Smooth)

Stall Turn  8/9  (Does it very well)

Rolls 7/9 (does couple with yaw, will need to be compensated with a mix)

Immelmann 7/9 (Check before roll, else it will barrel a little)

This maiden was with 20mm each of throw on aileron & elevator and 30 mm on rudder. Did the aerobatics in a very tight schedule (She coped with my high 'G' flying :)  )

I am adding a youtube video. This one is unique in that all routines are back to back, whole flying routine gets over by under two minutes, rest is, as they say History.

STRIBOG IS AN AEROBATICS CHAMPION REBORN

See for yourself, she flies so beautifully

Length :        125mm
Breadth:        140mm
Weight:         3.2 kgs

Thank you sir,

My bad :banghead: Corrected

This was built couple of years ago, nothing much though straight wings straight forward and a simple build, easier than Kaiser to put it together

It is even faster than that, i was controlling the speed, between 1/2 to 3/4 throttle. May be next video you will be able to see it
