Basic ?, How to remove the prop

[dennydm]

I, like quite a few folks here have fried the ESC (what ever that is?). I have searched the forum, the instruction book and horizonhobby.com but cannot find any reference on how to remove the spinner and finally the prop to allow access to remove the cowling.. I have tried prising the spinner to no avail. Help!

Pry harder. Just RIP it off. Use the FORCE.
It's just rubber and sometimes glued on.

Just curious, are you thinking the ESC is under the cowl? It is actually part of the receiver electronics box on the Super Cub. (all-in-one setup). If you want to purchase the same replacement parts as stock, this is what you need: search.horizonhobby.com/index.jsp?N=0&Ntt=super+cub+receiver&sid=12AE33DD3194

Be aware that these come in several channels (1-6?) I think there's a sticker on the bottom of the plane, and probably on the receiver, too. You have to match it to your receiver.

Unless you are looking to upgrade to a new receiver, servos, ESC, and motor. In which case, there are a lot of threads here to look at in the Motors & ESC section of the Form: supercubclub.proboards.com/index.cgi?board=motors
Here's a discussion we have been having recently, with some pics of my brushless upgrade... supercubclub.proboards.com/index.cgi?board=motors&action=display&thread=3382
It is a fairly costly process, because you have to change everything out, as nothing on the Super Cub is really standard or modular. However, if you are willing to spend the extra $125 or so (plus a radio transmitter) it is a very nice learning process on a very forgiving aircraft that handles crashes well. And many of the parts would be usable in another park flyer sized plane that you might buy later.

It is very likely that you can get Horizon to replace it under warranty. They are very forgiving in most instances. It is definitely worth a shot. Just be prepared to wait 20 minutes or better on hold for technical assistance.

It seems to thread itself onto the prop shaft (which is threaded)
I had to put a screwdriver through one of the cooling holes on the front of the cowl, and back into one of the holes in the central hub of the gear (which sits back near the firewall) to keep the gear from spinning while I twisted the spinner backwards. this also required bending the plastic edges forward to clear the prop blades as the spinner "unscrews."

FWIW, a new spinner is $0.99 at the hobby store, or the same if you order one, and since you will be ordering new parts for your speed controller, you don't have to worry about shipping fees if you order the spinner at the same time.

Here's what it looks like once you get the spinner off... The gear faces toward the back of the plane, and threaded part is where the prop mounts.

If you take apart the gearbox PAY ATTENTION to how the little parts go.

Thanks for the reply! After a seemingly minor crash the prop was pinned with the throttle on resulting in the smell of frying electronics reported in other posts. It is my guess that the ESC was damaged as the motor no longer turns in response to the transmitter. The plastic prop was bent and the prop shaft may or may not be affected. I tried the brute force method to remove the spinner first suggested but no success. I will try to unscrew the spinner as suggested in a later post. I am aware that the ESC needs to be, in my case, Channel 3 to match the transmitter. Keep your airspeed up, lest the ground rise up and smite thee!---Regards all

awww... the mysterious blue smoke escaped...
that's what makes electronics work.
once it escapes, you can't put it back in.
