Mine does the same thing. I do not think it is taking any load so I'm not worried about it.

I just picked up a CZC and ordered some real tires (and a rudder, after gluing the screw boss to the fuselage with "instant" CA), but have a couple of mod questions. I immediately swapped the plastic prop for a Zinger 15x6 wood prop and performance was perfectly fine, but that tiny prop looks wrong. I'd like to run a ~17" 3 blade with a Tru-Turn spinner. I'll be putting in a Castle Edge 75 with arming key, 10 channel Lemon RX with their telemetry system (planning on a 4 channel wing plus tow release and a cargo box with a drop door), and The usual battery tray system in her, but I haven't figured out what motor to go with. Any opinions on motor and pitch on a 17" 3 blade for running on 6 cells? I'm thinking around 8" pitch and 300 KV at a wild guess.

the plastic parts on the airplane. do things get brittle? wing struts, etc? i want to
put ski's on my airplane, but don't want to break anything due to cold temps.

thoughts?
I flew mine all last winter, in the teens, and single digits, never broke anything, but I was always careful while handling it, like loading and unloading it. Skis work great on hard and soft snow, floats work good on lite fluffy snow, I got tired of swaping them, so I just left the skis on the rest of the winter

It looks like you are the mad scientist to research a motor that will swing 3 blade 17" prop. A Zinger 15x6 may be over propping the stock motor. Don't complain if or when the magnets become delaminated.

Hey, how is a 15×6 prop going to be over propping that motor? The stock one is 15×5.5, that shouldn't be enough of a change to hurt that motor. I've heard from several other people on here and other places that a Zoar PJN 15×6 Beechwood prop is more efficient and provides better power than the stock prop.

Think POWER 60 motor will do all you need it to do, but you can always go bigger on the motor

Hoping someone would install the Power 90, 110.

All props are not created equally in terms of shape and rigidity. A Beechwood prop will provide more power simply because of its shape and rigidity. Measure the watts and you will see the difference. Dr. Kiwi test electric motors and the watts vary between prop brands and designs. For example, a GWS electric prop draws less amps that APC E prop with the same size and pitch. A APC prop in the same size and pitch consumes the most.

See for yourself and do the experiments and you will understand. Do you have a watt meter? Unless installed installed mountains overnight you are flying in dense air at 840 feet above sea level. Our Texas poster is at 121 feet above sea level. You could get away with a bigger prop if you wer flying at 6,000 feet.

Remember, the 5.5 pitch of the stock prop wasn't a fluke. Eflite reduced the pitch to that odd size for a reason. The power system is on the ragged edge with the stock prop.

Check eCalc, I believe it has 3-blade props to select in the list.

www.ecalc.ch

edit: yes you can set any # of blades.

Maybe the SK3 5055 320kv will do.

I believe they are talking about a 3 blade prop.

In my (RC) flying experience, am I to believe that most motor failures on this plane come from back-to-back flights?? I know the stock motor wasn't much to start with, boarder line on the esc that came with it, and seeing so many failures, is the newer ones got a different motor-esc combo??
