I bought the Nexstar RTF and it had a few adjustments once at the field. As far as the 20 mins....that is sooo bogus. Try about hour and half. Been a great plane to train on but it did bite the big one after four weeks. I was sooo upset! Ran home and order a Nexstar ARF that night and moved all parts to it. Bad part was explaining to my husband the rush to buy the ARF and not look for it on EBay. I have the bug and can't sit out on a training session waiting for EBay. Hubby is worried where this will led to.
