My magic extra 300L flies great but had a flame out and took the gear off the other day. But as far as the covering goes...I was reading the threads here about that when I got mine so I took a small brush and brushed monokote trim seal on all the covering seams. Seems to have worked I don't have any problems with the covering coming loose yet! Hope to get the gear back on and re-enforce that area in the next week or 2. No rush now the weather here in Chicago area is not what you would call flying weather!
