RE: Great Planes PLUMA 3D Foamie
This was my first foamie and had it since it first came out. Easy build, no major complaints other than the gear. Able to do rolling (harrier) circles that look like I know what I am doing, knife edge loops, easy to hover, plenty of power and great flight time on the outdoor setup. I am the type to want more power so I was hesitant about buying a stock setup, however GP got this one right. Other than the surge, I wouldn't change the motor/battery setup at all. About the gear, since the aileron servo sticks out the bottom, you pretty much need the gear, however after several landings, they like to twist around. After lining the wheels back up and gluing it several times, the slots became pretty worn out. I tried to solve the problem by grabbing it out of a hover. That worked pretty good until I slapped the plane out of the air and crashed. Pretty fragile, took some time to put it back together after that. I got my money's worth so have no problem buying another. Instruction manual had one oops as it wants you to cut the aileron push rods to 2.5 inches instead 6 something. Luckily that seemed weird so I didn't do it. Good thing, would have needed to buy more carbon fiber. Emailed support to let them know but they never acknowledged it. Oh well... Question to you electric guys, the motor surges a bit at full power, especially after a couple minutes flying. Then when the battery is about done, it surges at half throttle so good indicator to land. Someone told me they thought the ESC may be a bit small. Does this sound right?

RE: Showtime 4D 2C Engine installation
Hello all, I would like some help regarding the ShowTime 4D 90. We went with an OS FS-120 w/pump and balanced it at 7.5 inches from the leading edge (about where the triangle shape hole in the fuse is). I have test flown this bird now 3 times and been lucky to get it back on the ground. It is super sensitive to pitch and tip stalls very easily. In a 80-90 degree bank, I will apply normal back pressure and the result is a stall and opposite bank. When I attempt to land, a slight amount too much elevator and it will balloon terribly. I tried the cg forward (4 inches from LE) and the tip stalls worsened. Also to my surprise, even the OS 120 seemed a bit under powered, don't think it will hover, although have not tried (still just trying to fly it). What I could use some help with is the correct throws and expo settings. I really want to think this is a setup problem. Apologies if wrong forum for this question, first post.
