Repair the Whip?
Well Philly,
I don't have any experience with the DD, but having looked at photos of its construction, I can assure you that if one hit the tree that I hit, at the speed that I hit it, nothing would be left to repair. Having said that, the Whip is also unrepairable given that there is a nasty crack most of the way through the body and the motor mount is also cracked badly. (not seen in photo). Trust, me this plane was moving when it went in, not anywhere near top speed but fast enough to hurt any plane. Good news is I have a new one sitting on the shelf which I can have ready in about 2.5 hours, given that I now have experience building two of them!
We should sponsor a fly-in down here for those who want to learn how to fly off a cricket pitch and avoid the stands, the scoreboard, the goats, the mountain and the immovable gym at the east end of the field, not to mention the odd cricketeer.
Greetings from the islands, Mon !
