various planes, various problems

I have 3 planes, 1 working, 1 awaiting a new motor, and 1 never even completed.

1: Harbor Freight Tools; P-51 Mustang.
~Already has 4 channels, not giving it flaps, want to add RG.
+Selected the main gear from the GWS Pico (Horizon: GWSRGPM).
-Not sure how to install them, but there's a first for everything right?
~Gave it a really nice paint job, I'll get some pics up here if anyone's interested (see post #4).

+Want to go brushless for the lipo power and flight times.
-Don't want to take out the gear box because of the realistic sound.


Question(s): What sort of motor should I get to run a 6:1 gearbox with an 8" prop and draw less than 30 Amps on a 3s lipo? Is this something I should take up with the guys at the local shop, or would someone give me a PayPal-able link?

EDIT: After reviewing another RCG thread I found last night via Google Images, I have decided an eflight Park 400 3700kv should work fine running a 3-4 blade prop.

2: Great Planes; Slinger.
-I damaged the motor case and I think that caused it to start frying ESC's, not sure.
+Got a new motor & ESC on the way.
=Beautiful plane IMHO, 56mph on radar with an under size prop.

3: Multiplex; Xeno.
-never fully assembled.
-not shelling out $170 for the tuning set so:
+Used Eflight Park 450 Outrunner (shaft fits fine, but needs dubro pins).
+20A Grayson/Welgard ESC (flown together before, doing fine).
~I've worked with folding props before, however this 9" prop is tiny compared to 12", but saved weight should make up for it. (weight of the 450 vs. the recommended brick)

Question: Should I look for a reverse firewall motor instead, or will it fly alright with the weight slightly farther back and a trimmed-down shaft?


I'll be out of town/not working or checking back until June 23rd. Any questions after that will probably be answered depending on how many I get. (Or if they're just stupid questions. )

Thanks for any help!
