I don't see a super cub on his site.

The J-3 is easily transformed into a super with the addition of flaps and the super cub cowl. There are no better plans than his, outrageously detailed and dead scale.

smkrcflyer

That's a good idea I'll have to look into that.

Hmmmmm, just thinking out loud here. I have a H9 ARF Cub, 80" wingspan. Well, its my 2nd one actually. I saved the wings from the first one (should I say 'salvaged')? I was wondering about taking one wing and modifying it into a Super Cub wing to use the flaps. Are the wings enough alike to do this, I wonder?

Also, for you Cub experts out there, is the PA-18 and the Super Cub the same thing? If not, what are the differences?

Thanks,

Bob

Pretty much. Check out the variations of cubs at, http://www.airliners.net/ just type in Piper Cub, most, if not all, are based on the J-3 airframe.

I just got a Hangar 9 J3 Cub I'm looking for some fictional landing gear besides the robart they almost cost as much as the plane. Any info or designs would be helpful.

John_M_

p3arljam, what size H9 cub?... their 1/4 scale cub comes with full fictional landing gear (knock offs of the robart)... you can can get a replacement set for like 89 bucks.

Here's one site that's selling it for 80 bucks.

Or you can just do a search on google, and you'll come up with a bunch of results, one that may better suit your location.

It's the 80" wingspan version I checked around didn't see anything.

John_M_

Ok, that's their 40 sized cub I believe; not much out their except the robart gear... you can try Ebay for a better price, but its going to be a difficult one to find.

Thank you sir I might have to try and make my own.

Fiberglassspecialtiesinc has 1/4 scale super cub cowls to convert the 1/4 Sig cub into a super cub... not sure what Cub Man recommends to use for his cub plans; I'm sure FGS has something that will probably work well with his design.

Here's the drawings of the Robart 1/5 scale cub landing gear... its not drawn to scale; meaning you can't print it out and rely on the print to be used as plans to build over, but the measurements are correct... maybe you can use it for reference.


***Edit***

Here's a site that offers the drawings

The biggest difference in a J-3 and a PA-18 (super cub) is the boot cowel is considerably wider. You don't have to have flaps(the first PA-18's did'nt) however the fuel tanks are in the wings, not the cabin allowing solo from the front seat. The ones with flaps also had balanced tail surfaces (wider)

acerc

I know cubman was working on a Supercub and is near finished with it. I participated in helping him retrieve a cowl from FGS for it. He is probably currently busy with preparing for the fly in but I am sure he will be along shortly and can help with the differences as well as to which cowl was purchased, I don't remember.
As I stated yesterday the J-3 is the base frame for most Cub's, and the variations are nearly as numerous as there are owners. I would say the best thing to do would be to find a subject airframe and build to match.

acerc

Can someone tell me what the plans state for the prop washer spacing on the Sig 1/4 scale clipped wing. I can't find my plans and I need the distance.

John_M_

acerc, on the sig 1/4 j3 cub plans (not the clipped wing version)... the distance from the face of the firewall to the outer nose of the cowl is 5 1/8" inches... that's NOT including the clearance for the prop hub to cowl... that's usually personal preference (no more than an 1/8" of an inch)

BTW, no where on the plans does it state the firewall to prop washer distance, nor does it state it in the build manual... I did however take the measurements off the plans with my fancy machinist (stainless steel measure rule) and its definitely 5 1/8" from the FW to the outer nose of the cowl.


John M,

Thanks John.

The Cubs were like most small single engine aircraft of the Golden Era you have a lot of experimentation over the years by their owners. Things weren't as highly regulated as they are now. You had garage tree mechanics working on cars and airplanes. I know on the 1938 Ryan project there are a lot variations on the cowlings and engines in the surviving aircraft. It's like trying to identify the original instruments in the panel, no two aircraft seem to duplicate each other when you get 70+ years from the manufacture date.

Was the dynaflite PA-18 any good? Maybe I could find one of those kits.

John_M_

I've built a few Dynaflite glider kits over the years, but nothing in their larger kits ... their kit quality is as good as any other die cut kit out there... it's a decent looking super cub... all kits need some tender loving care as you build them, especially in the scale detail areas if that's what you're looking to do.

Not sure if this site is still selling the kit or not, but you can email them if you like... try ebay, google, etc.

That's all the help I can lend.

I built the dynaflite decathlon a few years back. Like john said, as good as any. It was a great flying plane and I miss it. I'd build another if given the chance.

smkrcflyer

I'm building there PT-19 now and it's a nice kit. Too bad they don't make there kits anymore they had some good planes.

Yep trying to tie up a few ends before my big fly in in KY June 7 & 8 the Warbirds and Classics over KY.
I have a set of prints for making ¼ scale landing gear. Looks like it did not make the move when I changed the website look. The prints can be scaled to whatever size you need. I will try to get it back on line in a few.
Looking at the cowl for converting the 1/3 scale J3 to a super cub by FGS has a few + and -…The cowl would be great for the conversion but if you are building a true super cub it needs a little work. The firewall for a J3 is a little more rounded on the top then the super cub. With a little work this cowl will work for a true super cub.
J3 and a Super Cub
As AceRC has said I’m working on a set of 1/3 scale Super cub plans. From looking at both full scale plans for a J3 and a Super Cub I have noticed the following options
The super cub fuselage in the cabin area is just a little wider.
Total different cowls.
The firewall for a super cub is flatter on the top then a J3.
Wing and struts are about the same except for the flaps on the Super Cub. I have also seen a Heinz 57 variety of wing spars and the way they attached to the fus for both J3 and Super Cub.
The outline of the rudder is different between the two.
The elevator outline is a little different plus the super cub has the (boost tabs) that come in front of the hinge line.
The super cub has a lot more instruments then a cub
Fuel tanks are in the wings and not behind the instrument panel
J3 had a small compartment behind the back seat, most Super cub have the compartment with a door on the same side as the cabin door for storage.
Super Cub ran a larger engine that also gave it the ability for a small electrical systems, this opens the Super Cub of to a lighting setup. Some J3’s have been modified to also have lights.
Super cub can be soloed from the front seat.
Super cub has seatbelts.
This is just a few of the changes off the top of my head.
As soon as I get the 1/3 scale plans ready, I also plan on making them in ¼ scale also.

As soon as you have the 1/4 scale plans done I will order a set as that is one of my favorite planes.

Cubman, what would you estimate the timeframe of the Supercub completion to be approximately?
