Note to all people flying alpha, the wings are very weak. In our club we tell all new guys and most of the time do it for them, EPOXY THE WINGS TOGETHER, but thats not where im going. The alphas will not take and high G loading compared to other H9 trainer or any other trainer. In the last 2 weeks the left wing pulled from the spar right outside were the metal wing tube stops. Everything else in this combo is great, but thats my only gripe. The last one that went in did not even hardly have a spec of glue on the sheer webs and ribs.
