Great Planes PT- 17 Stearman ARF

RE: Great Planes PT- 17 Stearman ARF
Did not use them so just talking here... Considering the kit uses CA hinges, I would think that 1/8" hinges would be sufficiently strong. There is plenty of thickness in the joint to use, the 3/32", however.

I put a Saito 200 R3 3-cylinder radial engine on mine.... and it is a joy to fly..... but nowhere near as cool as Linkan2's UMS 7-35 radial engine.
That is the definition of AWESOME !!!!

Any body know what the interplane struts are made of please? I hate so many fiddly bits (small screws and nuts) for assembly, so i would like to tap the strut holes (6-32 looks like a good fit), and just use cap screws.
TIA

I Did have to add some in the very tail above the wheel. 8oz ish,. But not too bad. I located the battery for the onboard glow as far back as I could. The saito 325 is by no means a power house but it gives about perfect power for this plane. Maybe I am just not used to draggy biplanes but even with this bigger engine I still want to get up a head of steam before any maneuvers. The sound makes it worth while! I wish there was some way to put video on here without having to youtube it!

Carl,
Thanks for the strut info. The chance of losing a nut on assembly seems pretty high to me, just want to reduce the assembly time and make it easier. I might experiment with jb-welding nuts on the struts. Scale is not really a consideration - I bet the surfaces on the full size are all bolted fittings, nothing like the way we build models, so why would we have to follow only some full size practices?

Would love to, but I would be forced to park it in the sun, and here in AZ, that equates to an EZ-Bake oven on wheels. I've seen people do it, but personally I don't like the idea of storing balsa, gas, batteries, and heat shrink covering in 150+ degree temps. Perhaps one day I will be able to build a 'carport' for it, got to get my kid thru college first! ( not much play money over the last few years!)

I just ordered a GP Stearman. I plan to power it with my ASP 400 five cylinder radial engine, I know that it will be over powered but one can always throttle back.
Best wishes and good safe flying.

HeliNuBee I bet you like the combination. The coolest thing is that you will be able to fly around at half throttle, I think radials sound sooooo good at that setting. especially on a classic bipe.
It should handle the weight. I have the boat anchor saito 325 on mine and it handles it really well.

Hey Chris, I'm sure I will be happy with the Stearman. I had the ASP 400 Radial engine in a CMP 80" Zero but the landing gear supports were to weak. The plane was quite heavy and it flew well but the landing gear mounts broke after each flight. I also have a GP Super Stearman powered by an FPE 40CC gas engine that performs very well. I also had a GP Curtis Hawk (before it decided to self destruct) powered by a PTE 36 gas engine that performed well too. Since I have experience with other GP Bipes, I think the PT-17 will work out well with the ASP 400. I do enjoy my radials, I have the ASP 400, a Saito 200 in a Sea Fury, a Saito 450 in a Gilmore Red Lion, and an UMS Evolution 777 in a BH Corsair, all are a lot of fun.
Best wishes and good safe flying.

I started my PT-17 Stearman build yesterday. I can't hardly wait to get that ASP 400 5 cylinder radial engine back in the air. It sounds so good.
