I will disagree with you. Two cubs in one week with the same problems. I've had many of the UM's myself in the last three year's with one or two minor problems. Really...two in the same week? I might just give up on this one for the time being. I just haven't decided. I am not impressed with quality control I know that. Unfortunate considering I liked how it flew for the battery and half I used on cub #1.
do you have your throws dialed down in your transmitter? just wondering...

Happy Camper!

CC arrived this afternoon, via UPS. Since flown 8 packs through, and all I can
say is WOW! What a wonderful plane. Someone earlier said HH hit a home run
with this one and I agree. Setup with 2 ail, 1 flap, on my DX8, as recommended in this thread. No dual rates, no expo.

Tried packs from E-flite 120, 160, 180, and the recommended 200, as well as a TP 250. All flew great. 250 requires just a tad more speed, but flies really well.
A stock 200 after 5 min flight (gentle throttle) had 7.96 v left in, almost 80%, so I'm looking forward to some longer flights tomorrow.

Only change I'm making is to move the control rods in a couple of holes for more control authority.

Got mine working, and some parts arrived from HH. Still backordered on the offset servos, so I installed a couple of regular linear servos from my UMX Extra 3D (it was dead).

I know these servos are made for AS3X duty, but they are working fine and this only be a temporary fix until the offset servo replacement arrives.

For now, I added an ail->rud mix to make up for the lack of aileron differential. I didn't want to put the brick in 6 channel mode and lose AS3X on one aileron. I also decreased overall servo travel on rudder so that the sum of the mix input + max rudder input does not go above 95%.

All is well, and the plane flies great!

I just got back from my first flight. It was too windy for a maiden but I did it anyway. Flew one pack about 5 minutes. No problems, no sticking servos, no crashes, no incident. The flight went perfect, just as I had anticipated. It just wasn't much fun in all that wind. So I packed it up and came home.
I don't think I have any other planes, except the beast 3D, that would have handled that wind. I think it was too much wind for the micro GEE BEE. Some of my larger park flyer's would have had trouble with this much wind.
I installed some larger wheels/tires before I flew it. I don't know what the stock wheels/tires weigh, so I can't compare it. But it sure looks better.
These wheels fit right on without changing anything.

Float PIcs

Here are my pics of my float installation. Pretty easy except for those tiny screws. They give you extra screws for those times you drop one and can't find it. Make sure to use the proper screw driver. One thats too blunt or too sharp will strip these screws also.

After seeing it with the grasshopper wheels in the mods thread I am definitely going to have to pick some up for my Cub, which is coming tomorrow

The deed is did.

We had half a gale blowing at the club meeting (photo when I get home) but I flew anyway. Grass field so I launched straight up at full power.

I had two or three nice flights including a couple of landings. Looped, did one very slow roll. Have to remember to use full power and fly FAST. Rolls at scale like speeds are very, very slow. Or at least the only one I tried was.

I think I have the elevator maxed out, but I could not spin in several attempts. Just a wide spiral dive.

Tried the flaps in both positions. Since most of the flying was at half throttle and the flaps take two seconds I experienced no ballooning even though I do not have an elevator mix in.

Used full power occasionally and also hung almost stationary at times.

Packed up

BUT

Later I flew a circuit to show a friend and landed short. Was gliding in nicely with almost no power. Hit the throttle either too gently or too late and flipped on landing. Very gentle but the prop shaft broke!

Managed to lose the prop and spinner to. I stuck it in my pocket but apparently not deep enough and it dropped out while cleaning up and putting the barbecue grill away. My flying buddy is the club chef and field meetings include hot dogs, hamburgers, marinated chicken breasts, soda etc! Maybe I lost it then.

I have a spare 180 lying around, dunno yet if the shaft is replaceable or what my prop options are. The landing was pretty soft and on cropped grass. It was the only flip and there is no other damage so I'm a bit annoyed. I've done much worse with several other planes.

Oh well, I may not get another chance to fly until next month anyway. My flying buddy seems to have lost interest in flying his third scale cub in favor of golf.

Think I'll build a boat and sail in Central Park

Here is an easy fix
This problem is widely known with the blade mcpx which uses similar (if not the same) servos. A simple fix is to remove the servo and remove the three screws on the back of the servo. These three screws fasten the motor and gearing to the circuit board.
Seperate the gearing section being careful not to disturb or touch the sensor pins (you will know exactly what is meant when the gearing is separated). Use a Q-tip with some alcohol to clean the black guide strip on the circuit board (this is what the pins touch when assembled).
-Reassemble.

Happy flying!
You shouldn't have to do this with a quality BNF bird. I barely have time to fly never mind fixing the manufacturers problems! I can barely find time to repair my own crash damage.

Some people (me for sure) had a bunch of trouble breaking the prop adapters on the Sbach. Check out threads here by ICU. He designed a prop adapter that is pretty well indestructable for these motors. He sells them through shapeways I believe. It will stop the prop adapter breaking. Or as an alternative you can use gws props either 5030 about the same as stock or the 5043, faster and save the prop adapter breakage. They are more flexible than the stock e-flight prop.

That's a bummer, I've nosed over in the grass a bunch of times, it's always with the throttle off on roll out though. If I do it right, I stay in the semi-bare spots on the grass and the landings are fine. She won't handle much grass even with 1.5 inch wheels.

Or just spray it with deoxit and work it for a while, then let it set for a few minutes then work it some more. I have had to repeat the sequence, but on my cc one shot did it.

Hoping to sneak one of these into the hanger when the wife isn't looking. Lol. I need a plane of this style since all I have are a beast v1, umx sbach and a um Stryker. Must get me one. Lol.
