. He was flying with a 20 year veteran instructor and doing fine until his approach and decent. Suddenly the muffler came loose the engine stalled and went into an unrecoverable spin and was destroyed. A friendly reminder to all. Always check everything on your plane before flight bolts,servos, fuel lines, battery charge, control surfaces,prop etc. By doing thhis you will drastically reduce your chances of inflight failure and also do your part to help keep everyone around you safe. After a while it becomes routine. For beginners make yourself a checklist. If your are not sure what to check ask your instructor or someone with experience. The only stupid question is the one you don't ask.
happy FLYING
