Default RE: Sebart Wind 110



Ok I have put some numbers in motocalc simulating Wind 110 on 4035-250 with 3 blade Xoar 18x19 on 10S 4900 Rhino, for the total weight of 4,2 kg and what has come out is encouraging!</p>

Couple of numbers: 70A with 2,5 Kw which is OK for the motor.Max. speed a bit low, 80km/h, due to pitch 9. Throttle at 66% for cruising.With a programmable brake on ESC with this prop the speed in downlines should be greatly reduced. Prop with the pitch size 10 would do better but unfortunatelu it doesnt exist!</p>

Other notes from motocalc:</p>

With a wing loading of 72,3g/dm&sup2;,
The static thrust (9319g) to weight (4195g) ratio is 2,22:1, which will result in extremely short take-off runs, no difficulty taking off from grass surfaces (assuming sufficiently large wheels), and vertical climb-outs. This model will probably be able to perform a hover or torque roll.
At the best lift-to-drag ratio airspeed, the excess-thrust (4576g) to weight (4195g) ratio is 1,09:1, which will give very steep climbs and incredible acceleration. This model can easily do consecutive loops, and has sufficient in-flight thrust for any aerobatic maneuver.</p>

So far I have had experience with APC, TGS, Aeronaut and Turnigy light electric props and by far the best Amps/performance ratio is with TR light electric props (probably the same as Xoar). The only problem is that they are extremely sensitive having very thin tips.
