Hello Steve and Phil . I have wound the bolts in , they just make it to bottom of mount. Do you reckon this will be strong enough?.There isno room to wind a nut on .Obviously I have never flown it or any other plane, so chances are I'll crash it but would like to make sure it's safe.My grand children will probably be there , and wanting a try.I also have a Topgun Piper Cub [ 80" scale ] , that was alot more expensive, hopefully it'll be a better model to put together. I thought I'd learn on the 'star and save some money,if you know what Imean. Let me know if you think I'll get away with my current fixing.I need all the help I can get. I have some plans for a VERON glider from late 50s early 60s if anyone is interested[ details on request ] . Thanks for your help. Cheers.
