My 2nd attempt on this plane. I am new to electrics, flew glow about 15 years ago. Loved the idea of a park flyer and just happened to live near a municipal baseball complex that has three baseball fields butted together with no dividing fences! First BLT (think of it as sandwich one) flew, but not very well on the standar electrifly 280gd 4:1:1 drive 10x4.7 prop. First landing popped off the motor and collapsed the wire landing gear. Yeah, it was a hard landing, but not that hard!! Reset the landing gear and tried a hand launch on the second flight (different area, just grass and no infield to ROG). Did not throw it hard enough to fly. Crash broke the stick fuse in two right at the landing gear. Placed pieces back in the box and started researching power systems and model design. Bought a e-flite park 370 and an e-flight 5:3:1 gearbox. Bought a wattmeter, many different sized props and several different NIMH batteries to ensure I wouldn't burn up the motor. Finally got a match with a 750mAhr 7.2v pack from Graupner for a severely crumpled Tipsy (story for another day). Running a e-flight 10x7 prop generated 12oz static thrust at 7 amps (motor rated maximun). OK. This time built the BLT (sandwich two) with taller landing gear, tipped forward slightly to provide more spring in the thing. Also, just used a 1/4 inch solid balsa stick for the fuse. Shaved the front and side to mount the e-flight Gearbox with the required down and right thrust. Used Dubro park flyer tail skid and pushrod assemblies. Ready to fly weight was 13oz!! First flight ROG'ed to a nice steady climb. I let it get two mistakes high and went to 1/2 throttle. No trimming necessary at all. Was able to do figure eights and loops. After about 12 minutes, I brought it down because I could tell the battery was getting "soft". Landed in the infield with no problem. Now, the acid test - hand launch! Switch to a fresh battery, full throttle and sandwich two just flew out of my hand! Two more practice landings and only a 10 minute flight this time due to the winds kicking up. Yes, it will fly in wind with the park 370 brushless, but I don't trust my flying skills. Now I have it in my truck extended cab ready to go at a moments notice!! Yay!! Great Planes power systems just are not strong enough for newbies. I need to get high fast to have time to react. Could not do that with the 280gd.
