I'm ready to go brushless on my Super Cub. I bought a "kit" by getting all of the parts for this great plane. Has anyone already converted to brusless? Can anyone recommend the best outrunner to install in this plane?

Great! Never really wanted to be the first - LOL! I will be using my new DX6 radio in what seems like a really nice plane from all reports I've read and seen. Thanks for the suggested power plants!

Here's the pictures of my motor mount.
First real flight was today. WOW this is a great set-up for the Super Cub. With the current thrust angles displayed oin the photos the plane flies straight as an arrow with all control surfaces trimmed flat and straight.
Check out this post, detailed are some COG troubles I ran into after removing the weighty stock equipment. http://www.wattflyer.com/forums/showthread.php?t=16919
Any questions please shoot and do let us know what you decide to go with in the end.

WJCJR: PM Sent. Also how was the servo conversion? I'd like to see a pic of that, either yours or another's. How hard is it to do? Do the old ones rip out pretty easily?
I am 90% sure I am converting my SC to Brushless this week, with a Spektrum DX6 and Phoenix 25 ESC. Nice way to blow $300 and an evening! (Still cheaper than a new plane though!)

Does anyone know of a less expensive alternative to the EFlite 450 brushless motor that provides the same kind of power?

My brother installed a $28 welgard in his...it flew equal to the other cub with a eflite 450. But we're getting away from Welgard, the shaft is made of really weak metal. He's on his third shaft. I would go with Himaxx...just a little cheaper than eflite, but one hell of a motor. I hear a lot of people using BP brand motors and seem to like it.

I led the servo wires aft - I have the receiver in the aft body compartment, leaving the battery compartment uncluttered.

I went to the LHS for a BL motor setup... they were out of the Park 450s. I got a Hacker A20-20L. Big mistake. I get home and see they are for 15-18 ounce aircraft. Our Super Cub is 26-28 ounces.
Luckily I can return it and get a Park 480. I want some strong power and the ability to use 10x6 to 10x8 props. This, and the Phoenix 25 ESC will provide the punch I'm looking for. Radio is a DX6.

Okay I got realistic and got a Hacker A20-26M, the recommended one on PeakEff-Pick A Motor. It'll still be about 113 watts/pound, which will still provide some good punch for the Super Cub. It's a bit more power than the Park 450.
Will use a stick mount and a 9x6 APC prop.

With the 450 and the 9.6V 1500 Elites I get tons of punch.
If you are getting more power with that motor choice you will have plenty to spare. As a matter of fact, I rarely go over 50-60% throttle otherwise the plane eats up territory quickly and a three soccer ball field sized area goes by awfully quickly.
Do you have experience with the Phoenix 25? I am impressed one can reinvent the wheel with all the features this thing offers.
Get everything hooked up and let us know.

No nose-ins, at worst a ground loop. I'd rather cartwheel a wingtip than nose in. I'm confident enough that I can keep the nose off the ground at all times! If it does break someday, I have about 26" of wood left to make a new one, and a 1/4" drill bit works fine for that.

I got some onboard video of the brushless:
http://www.youtube.com/watch?v=WFvnpfYEfb0
Flies great now, very quiet. Thrust offset not an issue, in fact I needed to trim in some right rudder to keep it straight.
The only downside to brushless is what caused me to crash on the fifth flight today: I can't hear it! I had flown about 7-8 minutes (including the video) on this particular pack, and I didn't her the LVC (low voltage cutoff). It was so quiet that I thought I still had power. Well, I tip stalled and it hit nose first into the ground. It broke the motor mount and cowl, but that was all. Stick mount still intact. The stick is 2/3 inside the airplane, a good 4-5 inches behind the firewall.
Also took off some weight, now at 2 oz. total noseweight and that seems to fly just fine. I need to get a timer now so that I don't end up low and without power again.

That is an awesome video! Way to go! Are you flying the Elite 1500mah pack from CheapBatteryPacks.com or a 3S lipo?
With all that power, I bet ailerons would be a blast to fly. Judging from the snappiness of the on-board video, I bet it'd fly great!
