    J4 gear versus pa18 gear

    Is the gear on a 1941 J4 available new?

    Can it be changed out with pa12 or 18 gear?

    Does anyone have good J4 gear available?

    Does anyone have used J4 gear for sale?

    Ki in Florida

    Any help would be appreciated

    Maybe Univair, they are restoring one right now.

    Nope.

    Anything you buy used will probably be junk.

    Welcome to the J4 and J5 orphan cub restoration club.

    I have a J4 that I restored in 2003. There is no new gear available from a vendor that I am aware of. I did see a set on ebay or barnstormers about a year ago or so. I had the internal springs fabricated and have two sets still, brand new ,if that will help. Cubclub might have a stc for converting to cub style gear. I do not remember seeing it listed in my research while rebuilding my cub. But I was not looking for that and so could have overlooked it. Pa12 gear would be about impossible due to the control stick setup. But I do not see why cub gear wouldn't work. You might have to fabricate it as I am not sure if the mounting points are the same. You might look at vagabond gear. It is kinda similar to J4,s.

    I worked on a J-4 that had been rebuilt by John Hatz and he had installed a
    Aeroneca gear and had it on a 337. The plane is still in the area, I might be able to get a copy of the 337. I flew it some and it was real nice.

    Don't mean to get off topic.....but I never knew they looked so much like a Champ. From a distance I would have bet it was one.

    Thanks for the information, I thought that might be the case.

    Just trying to buy it instead of building it.


    I never thought of champ gear, may be an avenue as well.

    Call Jim or Steve Dyer at Univair and see if they are going to make any. They showed me their project. They are doing an outstanding restoration. It might help the other J4 owners out there. Do you have a gear to start with?

    Blasphemy!!

    Keith, J4s are butt-ugly! How dare you compare one to a beautiful aircraft like the Champ. Head for the bar and wash out your mouth with the cheapest vodka they have. The shame of it all...

    JonB, do you prefer pistols or swords? Insulting my girl will not be tolerated. You can THINK she is ugly if you want but do not say it out loud. How dare you sir. LOL I think they look pretty good myself. But maybe because the J4 is kinda short and fat, like me. Champs don't win any beauty contests either in my opinion. But there is a saying about opinions.....

    !! Jon, Good one. I need that this morning.

    Now as for how good looking a Champ is........I own one but don't think it'll win any beauty contest. About like an average looking woman. Just good enough to please most people but not that runway model. LOL

    Pistols or swords? Well, I have a buncha pistols but no edged weapons. I have an idea: you bring a sword, I'll pack a couple of pistols! There is that old saying about bringing a knife to a gunfight, though...

    OK, Champs may not be as purty as a J3 but they look lots nicer than a J4. Champs are purtier than Chiefs, too.

    A clean C-180 looks better than all of 'em, though. As for opinions, I have a couple of elbows and one a-hole, if that's what you meant...

    Champs may be prettier than a J4, but J4's fly better and are more fun! Ugly girls are more willing to please.

    That's OK, Drew. Beauty is in the eye of the beholder, they say. If you think the J4 is a purty airplane, then so be it; who cares what I think?

    Isn't the J4 similar to the Chief - side by side with a yoke? Or does it have sticks like a Vagabond? Or, in the case of the PA-15, *a* stick; left side only.

    Would the landing gear be similar to the PA-15 or PA-17? A local PA-15 has no suspension at all, just the tires for shock absorption. I think the -17 has bungees.

    There is a beautifully restored J4 at 40I, but as I recall it has one door on the right side. Was the left door an option, or something that came along later?

    Sticks like the vagabond.

    PA-17 vagabond had two sticks and bungee gear....

    All J4's have 2 doors. In fact the very first J4 was on ebay last week. Serial 4-400. In 1940 they went to a pressure cowling, maybe late 39. And the tailwheel was initially a odd bungeecord system contraption. They were marketed as a business mans coupe. Kinda like the car business coupes of the day.

    the J4 has two sticks, side by side seating, only the left side has the heel brakes, the tail wheel had 3 options, 1- Type A-Air Associates(a funky bungee system), 2. Type B Heath 3. Type C- Uniloy GC-15 free castering.
    The Landing Gear consists of an Oleo Strut design similar to the Champ, although I believe the J4 was designed and built before the Champ. Pretty much all J4's are unique, I dont think there were many that were Exact of each other as there were countless Paint schemes and countless options to pick from evan a Hummer "rubber band" starte! From what Ive been told by Experts is the J4E is the first airplane Piper made with all Metal Spars
