Super Cub Bush Plane Configuration

[RCBob]

Forgive me for my inexperience, but I want to build an RC version of the Super Cub. The kit that I got is a J-3 Cub with a different cowl and mods to the plan showing what the tail should look like for a Super Cub.

My questions are: The plan shows the option for a clipped wing version. Did Bush Planes ever have clipped wings? If they had clipped wings, did they have flaps, or did the ailerons remain full-sized? If clipped, did the strut mount points stay in the same location -- that is, move inboard w/ the rest of the wing?

Again, forgive my ignorance, but I DO want to build as true to scale as I can. Thanks for your help.

RCBob,
For the purposes of your model, you could use the J-3 kit, move the little dummy pilot to the front seat, leave the wings full-length, add flaps if you feel like it, and modify the cowl to a pressure cowl, which means the cylinder heads are contained inside the cowl, instead of sticking out like on a J-3. Everything else would be pretty close to correct. Look at the photo albums on this site and you'll see examples.

Stewart,

Thanks for the reply. I'd much rather be flying the real thing, but Epilepsy prevents that - can't find a doctor to ok my medical! :cry:

Fellow enthusiast,

One of the photo albums has some awesome models in it. Where are you located? Maybe someone can take you up.

We got lots of cub folks in Minnesota, RCBOB that would take you for a ride...

All,

The aviation community never ceases to amaze me! Thanks for your kind words -- for those of you wondering, I live on the north side of the Twin Cities, near the Blaine airport. Any of you needing some extra ballast some time, look me up! I'll be happy to accomodate! :D

Bob,
I'd like to see some pics of the model when it's done. I've always thought an RC Cub on skis would be fun to play with. I'm not the best RC pilot though. It's a lot harder than it looks when you turn and the plane's coming right at you, the reversed perspective, I mean. There are some really good RC aerobatics guys up here. Fun stuff to watch.

Bob,

Just as a note, the clipped wing conversion was typically done to J-3s. It certainly would not be appropriate for a bush airplane, due to loss of lift.

Not sure if the Super Cub was ever approved for clipped wings under that STC, anybody know??

RCBob,

Sig used to make a great balsa kit a built up fuselodge with 1/4" basa stick, very good looking scale kit. A great looking machine and very tough. I used silk to cover my first to replicate fabric, wouldn't do that again. I had PMA for the rebuild work I was forced to do because of my talent at flying RC.
Built up scale balsa floats and metal fixed penetration wheel skies and had a blast. The skies were by far the more enjoyable of the two set ups, three if you count wheels.
Incindently the .19 to .25 motor was really fun to fly, very docile, but the .40 I slipped into it added enough spice :onfire: for real cub action, you know the almost vertical climb for short field obstacle clearance like the real ones we read about on supercub.org can do.

Thanks, all

I will be building it w/ a full - length wing. Depending on when I get it done, it will be on floats, skis, or wheels. I'm planning on a year-round airplane... looking forward to it.

Thanks for your input!

RCBob,

Don't waste your time modifying a J-3, just buy it:

Just remove those stupid wheelpants. :)
