[Canberrauav] Beavering About Jack Pittar jpittar at bigpond.net.au Sun Oct 20 22:45:04 UTC 2013 Great photography Matt. It certainly allows us to analyse what is going on. I think the bottle drop mechanism is close to optimum. However; the pendulum effect of the bottle under the drouge is quite prominent. We may not be able to get rid of this effect. The period of oscillation will be a function of the length of the string. More string is bad. It is clear that the glide speed of the Beaver is too slow to have adequate control. More fine tuning and practice is required.

Take off was nice and assertive.

[Canberrauav] Beavering About Jack Pittar jpittar at bigpond.net.au Mon Oct 21 05:48:41 UTC 2013 Flaps are normally used to allow a lower speed for landing. The problem was lack of control at the lower speed, so I am not sure how this would pan out. Maybe more control over the surfaces in FBW mode is needed, or better piloting is needed so the aircraft does not get into the situation where more control is needed. The model does have flaps and I will implement them in the rebuild. I must admit I did appreciate the power available on takeoff. It looked like there would have been trouble if it stayed on the ground much longer.
