I helped my older brother (by two years) build one from the kit around 1974-75. It was our first flapped build. We had no idea about setting up the controls so went for max deflections on both the flaps and the elevator. He was not big into the built up fuselage deal either (after a great build on a Ringmaster Senior) so turned it into a profile with maybe 3/4" or 1" thick plank fuselage. We put a Testors McCoy Series .35 on it, which was a bugger to get started,..but it was all the BX had in stock. It flew o.k. but we could not get it to do much other than straight and level and a dives and climbs as I recall. I don't think we ever got it to loop. Again, most likely due to our control set up. The trike gear was neat, another first for us. I remember that it had a very good glide when the power was off. Don't have a memory of what happened to it now that I think on it.. This was while we were stationed at RAF Wethersfield in the U.K. . We returned to the U.S. in 1976 and I don't know what happened to that plane. I remember giving and or selling a bunch of built up stuff as we did not think they would survive the transit back to the states.
