I ha e a Great Planes 90 - 120 Boeing Stearman in need of new upper and lower wings. Can anyone help point me in the direction of a plan? Preferably 72 inch span but I can scale from any size.

If you're just looking for a Stearman plan, the Sterling version is pretty accurate although the cabane fixings will likely be different. It's on Outerzone as a free download.

Thank you for the replies.

The demise of said Great Planes Pt17 Stearman was not painful for me, as I bought the remains after a crash occurred when another modeller's Stearman flew into trees. This was as a result of a 3 axis gyro rx detaching from its location, causing the model to get disorientated. Sadly I did not get the written off wings, one of which remained in the tree when the fuse fell out. I can easily repair and recover the fuse and tail, but have to do the wings from scratch. I like a challenge and have always liked the PT17 type. I also have a spare Laser 150 to re home.

I have found the Outer zone plans and downloaded them.

Can anyone advise how to print the pdf file such that it prints actual size on multiple A4 sheets? Mine wants to reduce the 3 large pages to 3 very small A4 sheets.

2 things Phil

" Tileing " is an option on your printer, so in options you will find the choice to tile when you go to print


3 axis gyro

After the whole installation is complete, glued, screwed and adjusted

Drill holes it you have to, but put a tiewrap around the unit

Hi Phil,

On some printers there is also a poster option. I've printed a couple of plans out this way and found you can have a slight matching discrepancy when assembling the pages. Some of this is down to the printer registration tolerance 1-1.5mm is not uncommon. To keep this effect to a minimum make sure the paper is well fanned out and airiated before it's loaded into the printer and also ensure the paper feeder side guides are as tight as you can get them without restricting paper feed.

Thanks all. I found a local print shop and they are printing the Sterling plans forme with 12 % enlargment to give, I hope, the needed 72 inch span. I won't be putting a gyro in this one.

I fitted a gyro to the rudder on my GP Super Stearman because it was squirming all over the place on take off. I hadn't had a problem with it before and that cured it. Then I remembered I'd had the same problem with a Precedent Funfly. No-one at the club (even the aces) could get it to track properly. I replaced the wheels which were a sort of foam and the problem disappeared. I did the same with the Stearman and replaced the well worn wheels and all was well. I should mention both clubs I've flown at had hard runways.

I crashed my Stearman on the second flight because of an engine cut at a very awkward height by tip stalling. The fuselage wasn't too bad but the wings on one side were badly damaged. I'd had an engine cut on the maiden, too, but at height so I was able to save the airframe. The engine is a 30cc Mackay petrol and the eventually I pinned down the problem to a faulty ignition unit which I replaced with a HK one and not had a problem since.

I picked up an old one and used those wings after repair on my fuselage. So I have a spare fuselage and perhaps the damaged wings (I may have thrown them away in a garage clear-out). I bought the wood to scratch build new wings but never got round to it. I'm afraid it's a bit of a hangar queen because it's such a pain to assemble at the field, it's still on Mux 35Mhz, and I'm so used to taking a few LiPos to the field rather than a can of petrol etc.


Still a lovely model, though.
