by the way i changed from the 3 prop propeller to the 2 bladder during the useing the 4 cycle fuel due to some rough landings and all i had was 2 blade props left.i was gonna use them in the future but it didnt work that way.the props are the standard ones for the alpha 60 trainer.she really screams with that 2 blade prop.i love it.sad thing is im on my last one and hobby store is 40 miles from here[] ok guys sorry about all the post but i just wanna be succesful.my skills r getting better fast.by the way if any new guys wanna fly there bird for the first time get a instucter.u may not want to but its very important u do.even if u just have one session with the instucter like i did and about 6 flights on buddy box.ur chances the next time u go up on ur chance of soloing on ur own will be much much greater.i no for a fact when ur by urself soloing u get a way larger butterfly in ur stomack than with a instructer.its a high that u cant explain till u experence it.later ill let yall talk now lol.im just wasting time so my batterys can charge glo plugs etc.
