The last flight I had I noticed a bit of wing flutter, nothing catastrophic, but I decided to put 6 oz of balast to make it similar to my X-15 and ALCM and bomarc models which don't exhibit any flutter....The X-15 has a similar wing shape and construction so I'm hoping it is just getting too fast on boost, this worked for my ALCM that started at 33 oz and I balasted to 40 and it got rid of the problem. I did not see this in previous flights.
Here is the latest video, note that it was not a purely vertical boost, this was the first time I was flying it from so far away....that would increase airspeed as well...I think given the 6-7 oz/sq foot wing loading I think the glide won't be impacted that much.
