I maidened my 4* this afternoon.....successfully.
Not without a bit of drama, though.
The controls were VERY twitchy, the plane wanted to roll to the right, and climb. Got the elevator trimmed out, and added a couple of clicks of aileron trim....if anyting the roll got worse. Brought the plane back around into the wind, added a couple of more clickes and now it is really getting bad. Finally realized I was adjusting the trim in the wrong directions. Doh!!.
About the same time I realize the reason the controls are so darned twitch is the TX is on high rates. Now I'm fighting the roll, and trying to remember which switch the rates are on but don't want to take my eyes off the plane to make sure I'm grabbing the right switch. So....forget the rates, and just get the darned roll trimmed out before it rolls all the way over on it's back.....oh, and by the way it's a lot faster than my Alpha and now it's far enough out that ........well, it's just too far out. Sooooooooo.....take a couple of deep breaths, keep it level and get it headed back to me. A couple of more passes and the roll problem is taken care of.....mostly. On the next pass I get it slowed down and decide that discretion is the better part of valor, cut the power and land it. Nice smooth landing, taxi it back and cut the power. Five to seven minutes in the air.
Went over the plane in the pits, checking all the mounting hardware is still tight, refill the tank and get an idea of fuel consumption. Fill up the gas tank. Verified the high/low rate switch.
Second flight.....now on low rates. Got the roll trimmed out, and made a few more passes getting it to (almost) straight and level hands off. Did some slow flight 3-4 mistakes high, a few more circuits, and landed again. Another smooth landing, and taxi back.
Dorothy....you're not flying a trainer anymore.
This is gonna be a fun plane to fly, as soon as I get a bit more comfortable with it. It needs a couple of more flights to finish the break-in that OS recommends, but the engine started and ran like a top. I think I'm gonna like it. I've never flown with expo on the trainer, but I think I'm going to program in about 25-35% before taking it up again....tomorrow if the weather holds and I can slip away from the family for a bit.
