I have a friend's "baby" F-16 in the shop right now we're trying to get flown, should happen in the next couple of weeks. Haven't put it on the scales yet - I don't feel like there is any way it's in the 20+ lb range, but now I'm curious. I'll try to weigh it tonight. We have a JetsMunt 70 in it for power. Original owner used an old P-80.
I have been having fits with the gear, the airplane came with a box of what must have 12 or 15 bent main gear struts, and I had to get one more - BVM no longer supports the gear but luckily they were able to scrape their parts bin and find me one. I thought about looking into converting some other gear (Chris above mentions HSD, I was thinking that one or the T-One gear) but hopefully won't be needed.
