I have been flying a 2002/2003 quarter scale Hanger 9 Super Cub for the past couple years now. It is electric using an Axi 5330-18 motor with 10s 5000mAh or 10s 6500mAh lipo packs for power. Speed control is a Hacker 110HV and flying tows using a Xoar 20 x 8 electric wood prop.
The plane flies great on 1/4 throttle for general flying, and has enough power at full throttle for 3 to 4 full tows of sailplanes in the 4m to 5m range (up to about 15 lbs max).
I was able to find another one new in the box in the past year and have it just about ready for the motor install and final control surface connections. The motor for the second will be a bit more powerful....a Hacker A60-18L that I will fly on 12s 5000mAh lipos using the Castle Creations ICE160HV. I haven't determined the prop yet, but probably 20 x 12 to 22 x 12 range.
Both planes have been built with Ben Diss tow releases and I have modified the fuselage to reinforce for the release as well as the added servo that controls the release.
I don't have data yet for the new set-up, but the Axi has measured about 1700 watts power based on the 10s set-up with the 20 x 8 prop.
I am hoping to be in the 2700 - 3000 watt range with the new Hacker motor.
Here is just a general picture of the Super Cub (shown with a Master Airscrew electric wood prop 20 x 8 in this photo). I will also post more detail pictures of the tow release install as well as the electronics when I get a chance in the next week or so.

I have the same airplane but outfitted mine with a DA-50. Lots of power to weight. Pulls most sailplanes up to 22lbs. Not bad; considering we fly at 6200' in elevation.
One thing to keep an eye out for on the Hangar 9 Super Cub is that the tail is VERY weak.
Mine broke and a friends broke as well. See Picts
Thanks for the information Bill. I have been fortunate with mine so far.
I received the Hacker motor yesterday along with the mount. I should have some pictures of the progress today for the installation of themotor and electronics.
I changed out the wheels for some 5.0" ones from Sullivan and I have kept the stock aluminum landing gear........not really any problems, although the axles can bend on a hard landing.
The tow release is a machined one from Ben Diss. I don't know that he is making them anymore, but there should be some still avaiable through a couple sources. Alex also has some tow releases and there are a couple other companies out there that have them.
I'll post some pics later today of the vairous components as I get going on the new fuselage install.

Here are a couple pictures of the current Supwer Cub using the Axi 5330/18 for power with a Xoar 20-8. Power is about 1700 watts on this configuration.
Also shown is the Ben Diss tow release that uses a JR DS9411 servo for actuation.
These are some of the new electronics going into the number 2 Super Cub........the motor selected will be the Hacker A60-18L using a Castle Creations ICE 160HV esc, running on 2 6s Hyperion 5000mAh 35c packs (to make 12s) and initial prop will be a Xoar 21-10 3 blade electric wood.
The picture of the 3 motors is for compariosn: the Scorpion 5535-190, the Hacker A60-18L, and the Axi 5330-24.
The receiver is the JR 1222 with 2 JR VR610 regulators, which will use 2s Hyperion 2200mAh packs to provide power for the receiver and all servos.
Again I am using the Ben Diss tow release, but the tow release servo will be a JR DS8411.
The picture of the fuselage with the 2 elevator and single rudder servos installed. Very spacious right now, but it does start to fill up as the equipment and batteries get put into place.

Bob,
Where will you mount your batteries? Whoops just remembered you won't have that fuel tank there. duuuhh
I made my tow release out of one of the metal eng mounts. Drilled it out and sleeved it with a teflon tube and stuck a spring steel rod through it all. Had to cut through the covering and then stuck it all up.
So don't throw those mounts out!! I can send some pictures if you like.
I made a bulkhead and bolted everything down. I also used blindnuts on the airframe; so that the bulkhead is removable for whatever reason..
Hopefully; I'll do some towing with it tommorrow. Never towed before; was always on the end of the tow-line. Our usual tow-pilot is out.
The Cub has proven itself before.
I've just started a 1/3rd scale BUSA Super Cub. What a lumberyard!! Putting a DA-100 in it!
Bob,
I noticed that in post #6, picture #2, the tow release wire in the "hooked" position should be level with the surface of the head of the tow release. Not only will it put less strain on the servo, but it will also shorten release time.
Bill: the batteries actually sit on the area just over where the wheels and aluminium wheel mounts are attached. I make a ply plte with bracing and velco straps and also have velco on the ply plate the batteries attach to.........seems to keep them in place pretty well and also doesn't offset the CG......there is room for forward and backward movement to adjust for the cg. I'll post a picture when I get a little farther along with the install.
Mark, thanks for your note. I actually have the release pin just slightly high to verify it is in place. The release time is virtually instantaneous due to the speed of the servo and also the servo is actuated with an on/off retract switch. I haven't had any problems......yet...........but of course that doesn't mean it couldn't happen.
