Piers Bowlan Posted September 30, 2016 Share Posted September 30, 2016 Like kc says, if the spar is OK it just looks worse than it is. A couple of 'part rib's' and a bit of sheeting to rectify. As long as you can get it all back together straight and true it will probably fly fine, if a little heavier. Definitely quicker than building a complete new wing panel. A couple of hours 'midnight oil' to rebuild it and another hour to recover. I would give it a go at any rate. Good luck and have fun.

Low pass Pete Posted September 30, 2016 Share Posted September 30, 2016 Hi Craig One of the advantages of good old balsa is that repairs are always on the cards. I once crashed a Balsacraft Mustang in a vertical dive. It flew again and is still going many years later and is now with another owner. As long as the structural parts can be maintained all should be well. Good luck with repairs. Peter Quote Link to comment Share on other sites More sharing options...

Craig Thomas Posted September 30, 2016 Author Share Posted September 30, 2016 Just to confirm guys. The rear spar it broken in 2 places. I don't know about the 2 front ones yet till I remove some of the front sheeting. I'll keep you posted. Some time next week I dare say.

Low pass Pete Posted October 1, 2016 Share Posted October 1, 2016 Araldite or any slow setting epoxy can fix a multitude of problems. Plus some inginuity as well. Edited By Low pass Pete on 01/10/2016 08:20:07 Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted October 1, 2016 Share Posted October 1, 2016 And to be quite honest white glue,and most other glues are stronger than the wood anyway. ive minute epoxy is far stronger than any wood so that is what I use when I need to. Sorry for the inadvetant touching of two keys which gave a rather rude wrod Edited By Peter Miller on 01/10/2016 10:45:10 Quote Link to comment Share on other sites More sharing options...
kc Posted October 1, 2016 Share Posted October 1, 2016 White glue and a bit of patience for gluing in spar repairs. Cyano probably best for repairing small cracked sheet areas. I suggest it's best to repair the rear spar first before stripping the LE apart and disturbing the front spars which might be broken. . Try to keep the wing straight and glue a new (bit) of rear spar in place whilst that wing half is flat on the board and the other half is supported to maintain any dihedral. Put the new part ribs in at the same time as the new rear spar. Let the glue dry whilst still flat on the board and weighted down as necessary. That should ensure no twist etc are introduced. Glue the servo support bits back in place. Then examine the front spars - replace or repair one at a time allowing glue to dry before starting next spar. If the rear spar does not repair well and the wing is not straight either re-do until it is correct or think whether it is better to build a new wing half onto the good half.
