Well I've had six of these little bypes and talk about a ball that is an understatment.On my laast two I had TT40s on then and they just flew just fine for me. On all the plaanes I had everything at 0 degrees and never r3ealy ballooned on me. Did loose upper wing on one and it didn't matter how much up I gave it it still came down. But it stil is a very fun plane to have and do it up any way you want it show us your covering talents. I do plan on getting one of these little butes back up in the air cause you don't have to disassemble them to transport it.
