Update.
I had an snafu with the plans (my fault) and the elevator wound up at too high of up incidence and it was hard to control. Having fixed that it flys really well. I am happy with the slow speed performance and the rolls and loops are very nice too. I don't think that the flaps were necessary, but oh well. I will try to get some video, but it is going to be windy here for the next week or so. It would be a great time to do some super chipmunk building. Hint hint hint
