Piper Cub J-3
« on: September 29, 2016, 07:36:42 PM »
Has anyone built Piper Cub J-3 f or Controline Scale? If so what plans did you use and how big? Are there R/C kits out there that could be used? I have one of the SIG kits, but its a little bigger than I wanted to use, something more in the 50 inch wing span area.

Sig used to tout the fact that their kit too CL Scale honors at the Nats one year.

IIRC the basic kit is a six foot wingspan, and the Cub has a pretty high aspect ratio.  You could get documentation for a clipped-wing and make it to that.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Gerald,

Great Planes made them in a few different sizes, three I believe. Your interest would be the smallest? 50" I think.

I made correct scale graphics for all of them, they were very popular models some years back and many built them for 1/4 and 1/3 scale. This is all R/C.

There is a "Twin" J3 Cub, actual aircraft. A Cub with two fuselages. Extra points there if you compete with it.

Here's a scale model of a J3 Cub sporting CFC Graphics. Looks real.

Good luck.

People use such planes because of the small scale factor, 1/4, 1/3 or even 1/2.  The model flys just like the real thing.

Catch 22:  the judges expect A LOT more detail on a plane of this scale.
Catch 23:  they've already seen a lot good Cubs.

AMA plans service lists all sorts of Piper Cub J-3 models.  Most are FF in all sizes.  A couple of bigger RC ships.  However, there are two listings that might interest you.

One is the plans for the Sterling kit.  Can be built for RC or CL.  Span is 54"

The other is for RC.  Published in Jan 55 Air Trails. 50" span.

Greg, the AMA Plans guy, will scale any plan to whatever size you might want.

Gerald,
Julie Able won the Nats in Jr with the Sig Clipped Wing Cub kit. It's 56" span.

One of the things that I've learned from flying stunt is that going to contests, doing your best, and not winning, can be very rewarding.  So if you want to model a J-3, just do it.

Take note that the Cub pictured has flaps and a pressure cowling. That would make it a Super Cub and would indeed be soloed from the front seat.

Been flying the full size ones since 1979.

You can solo a J-3 from the front, you just have to be careful wheel landing it because it's a little nose heavy. Not saying one should... just that they have been.

When I flew a J-3, I chickened out and sat in the rear seat.  Not fun!  Take off and landing a particular challenge because of poor visibility over the nose from the back seat.  Also, I had to lean forward and squint to read the panel instruments (such as they were).  Really only interested in airspeed to set glide.  The others really not necessary.

If it ever happened again, I would bring along a bag full of sand for the rear seat, and sit up front.

Try instructing ab-initio students from the back seat especially the larger ones.
Your only references are the side windows and your ears.
It can indeed be interesting at times, especially when you throw in a crosswind.

Citabrias and Champs are much friendlier since the airspeed indicator is on the left of the panel and is somewhat visible if the student leans to the right.

Several years ago I built a Sterling J3 with a ST. 35 int. Flew really well. won trophies at 2 or 3 NW Regionals and 4 firsts and one second at local meets. Every now and then I see one for sale on E bay. Wing was 48 or 50 inches.

I fly a Piper cub with a 80" span and is powered with a .46 sized engine. The model weighs about 7-8 lbs and is not a problem in terms of line tension. The bigger you build the better it flies and easier to hide the hardware inside the fuselage.

It was built from the Hanger Nine ARF kit and is now over 20 years old

I've entered C.L scale contests with models having

fixed landing gear

no flaps

no engine speed control

no bomb drop or other "tricks"

I didn't win anything.  Reasons noted above.  Still, had a good time--at the same time using models I already had.

Enter a J-3 and you have 2 strikes against you already.  The advantage is they are fun to fly, and look great in the air.

These guys that compete know all the "Tricks." They make sure their plane can do them also.

Why go home without a Trophy.

There are some that enter just to fly and then there are the die hards that do every thing possible to win. H^^
