I put the sensei together , checked it out a bit on the bench. I put a pair of packs in it and flew the sensei and it is pretty nice. It's pretty easy to fly too , but I don't have a good landing area. The wheels tend to sink into the wet grass/mud. I think I like a little plane better. I hand launched it and will give it another try soon. This is as big a plane as I want to own right now and hand launch. Second flight went very well too. Flew for 15 minutes using only half batery capacity. Landing is no good still.
