Flight report update....

I got a few more flights in on the Twist today. Last night, I checked the rudder out to make sure it was OK. I wondered about it since it seemed a little weak while hovering and also while in knife edges. Surprise, surprise, I had installed the wrong servo; a 625MG rather than the planned 5625MG which made for difference of about 40oz. of torque, non-digital vs digital responsiveness, plus a speed difference. Suffice it to say, with the right servo installed, the weaknesses were cured. The rudder was very responsive in a hover; just the way I like and the KE passes were far, far more consistent. It also seemed to help with flat spins but that may have been me just getting more used to the plane.

I tuned in another 200rpm on the engine since it has more run time on it and pull outs were improved as was fuel economy. Based on todays flights, I think the tank will be good for 20 plus minutes of flying with reserve. I don't use that much full throttle; only in climbs to set up for spins, etc. so I'm sure others will burn it up more quickly. I may look at installing a smaller tank to help lighten it.... nah, on second thought, I need to remember just how lazy I am - it'll never happen.

Something else I've noticed that's worth mentioning; the covering has really loosened up during the first two days of flying. I had been impressed at the out of box covering condition but now it's looking a bit ragged. I'll tighten it up before the next outing but I hope it's not a sign of a problem.
