Bad crash- needs a new motor? How do I install?

[snowpony]

Hi everyone,

I am new to flying (just flew 2 days so far) and had a really bad crash yesterday afternoon. My Supercub did a nose-dive and it may need a new motor.

Will it be difficult to put in a new motor and will I need to re-wire anything? Also does anyone have any good links or books that show diagrams on how things should be wired and assembled?

Under the advice of the hobbyists at my field, I already have many needed items- precision screwdrivers, 5-minute epoxy, foam safe CA, Zap, etc. I've already had a few crashes and have learned to put this plane back together, but this is the first time I think I may have messed up the motor. The Fuselage is in 3 different pieces and I will try to see if it's salvageable.

Any advice would be great- Thanks!

Are you sure the motor is bad? It's pretty tough for them to get damaged in a crash. Maybe just the prop shaft and/or the motor mount needs replacing...Those are pretty common items to get damaged. It may have unplugged itself if the crash is bad enough.

If you need to replace the motor it is very simple to do. There's either two or four screws holding the motor on to the mount. The mount also is held on to the firewall by four screws. If you buy a stock motor it will already have the wiring and the pinion attached. There are only two wires to unplug, red and black.

Thanks Zeta30, you've been a big help!

I'm pretty sure it's the motor, but I'm relieved to see that it will be an easy fix. I'm just glad there are forums like this where I can seek answers.

Digital cameras are great for helping you get stuff back together correctly.
As Zeta said, tough to hurt the motor itself since it faces backwards.
Not hard to mess up the shaft or the firewall.

Take a good look, take pictures, put the puzzle back together.
Make sure you check stuff that doesn't seem broken. There is often more extensive damage than expected in a bad crash in collateral areas. The shock goes everywhere.
