I need help where to buy or (better) get plans to build a Cessna Skymaster 337 or O2 from scrach.
Thanks,

Wendell Hostetler has a 337 plan and it looks good as a 02-A. I love the O2-A, but i am racking my brain to figure out how to make retracts for it. Really nice airplane. Here is the link=

Will check the site.
I flew about 300 hours a real Skymaster and saw the mechanincs make severals retracts of the landing gear.
It's really a complicated thing, but not imposible to replicate.
I have in the attic an old VHS showing the maintennance work on the 337. Will search and try to find someone to digitalize it...
Thanks,
Daniel

Just received my Hostetler 336 plans this week. Had them reduced to 20% scale (91.2" wingspan). Nice set of plans.
Going to build the 337 version, and currently working on design for main gear retracts using two air cylinders. One cylinder will pull both main gear down and the second will rotate the assembly back and up (requires a sequencing valve).
Long term side project.

If you do want to go through that retract problem then just build the fixed gear 336 version with wheel pants. Lots of documentation out there.

Did the millitary have any 336's in combat or where they all 337's with retracs. I got my planes in from Wendel last week and would like to have a O-2 but with fixed gear. I'll just have them stuck in the retracted position if I can't find a mill 336 to model. I dont care for the wheel pants at all on this plane.

No Sorry the 336 only lasted the first year or two of civilian production then the 337 was introduced and shortly after came the 0-2. Was a wonderful airplane to fly but sure would not want to be paying the maintenence bill on the rear engine.

John

LOL Yeah, they went through hell trying to give 50 extra MPH to that 172.

hi , does any one hace the plans for a skymaster for two .40 engines??
if not , just need the measures , max weight , engine and wing pitch, or any sugestions.
best regards

Slat:

I'm confused. First you say you want plans, then you talk about "Scratch built."

So which do you want to do? Plan build, or scratch build?

Sounds like you might be planning at least partial scratch with the gear, so why not go all the way?

While there is some pride of accomplishment from building someone else's plane and having it fly, that's nothing next to doing a scratch build, start to finish, design and construction, all your own.

LOL Damn, Bill give it a rest allready. Just kidding good points.



zanati, MAN has plans for a 40 sise plane that is called the "Airmaster" It uses one 40 in the nose and a old crank case with prop and spinner on the back. You could do some mods to the desighn to make it use two 25s.

I think I got the retacts simpled down some.


The tacs will be mounted on a rotating block.

1 doors open and tracs close togeather so they now legs points strait down and wheels are at 45`.

2 block rotats back and legs go up into planes belly

3 doors close


Block is rotated by a electric motor running a worm drive.

Have to find big ass retracs that can be set only to close at 45`degres

Here a pic of one with gear in motion..( pic from a old flying mag) i work on alot of them here and small airport .guy has a small fleet of them like 14 or more.. and one 336.. i try to get some pics of one on jacks for retrack test and get some pic's

What a damn nightmare. Mine wont be scale I tell you that!

i just finish my cessna skymaster from wendel hostetler ,test flight will be next week , if ant body like to see cessna please click my gallery att mario tavarez

mario, may i ask you how many degrees of incidence did you use for the front and aft engine mounting??


thanks

juan cruz

A very impressive project indeed, Mario nice job.

John

Real nice Mario. Have you flowen it yet?

baldeagle next sunday will be text flight , i need to do the cg after that the cessna will be ready for sunday

Danial Royal used to mahe a kit for the Cessna and the plans showed true scale outline. Royal is made by Markuta <,Something like that> now. Hobby Barn in Tuscon handles their kits.
Mario good luck on your madin flight.

Hi
I'm looking for a 337 (push-pull) project w/ about 40" wingspan to make it twin electric !!!
Anyone have experienced this?
Recomendations...
