The 2.4 would work ok. I had a Fox 2.4 on my Patty Wagstaff and it was not overpowered at all. With the 2.4 I would not have to add 18 oz of lead to the weight box provided.
I think I will go with the 180 Saito though.

I just bought my GP Super Stearman from my LHS (Brands in Providence RI). He has ordered a batch of them and they sold pretty quickly. I was going to install a spare Saito 120 that I had available but I was convinced that the G26 would be a perfect fit for the plane from the size, weight, and power perspectives. By using the G26, I won't need all the suggested ballast and I will save on the fuel.

I can't wait to put it together and try it out. Is anyone flying it yet with a G26???

Slaving the servo's would do away with the connecting stick..This would be done either with a Y-connection (ie. top left with bottom left, top right with bottom right), or assigning each servo to a channel, (ie. using a computer radio and assigning each servo to a channel and mixing them altogether..
The orginal Super Stearman had the connecting rod..

I'm using the connecting rod on mine. Not just for scale, but for weight and simplicity as well. The ailerons are quite small and this is no speed demon, so a single aileron servo per side should not have a problem at all as long as torque is in the 75+ oz. in. range. I'm going to use a 6 volt system with Hitec 475HB servos on all surfaces in mine. I've had great luck with these servos and they are about the most capable little servo available for the price. Unfortunately, I have not had much time to work on my plane and I will be travelling on business this week. All I've done is built the wings and installed the tail group and landing gear to the fuselage. Other than the totally unacceptable hinge slotting from the factory, everything so far has gone together great with super high quality components. I especially love the landing gear.

I just sold my little kyosho stearman on ebay and now Lord willin I am going to get one of these. I will most likely get the G26 first and then the plane. How does one if at all break in a gasser? I am looking forward to this. Has anyone flown theirs yet? Any more pics?

The G26 is a super easy engine to break in. I just use an ashless oil like Lawnboy, Ryobi, etc. mixed at 32:1 with regular unleaded and run a gallon or two of this through it. After a couple of tanks of ground running, the engine should run good enough to fly and you can do the rest of your break in in the air. Once the engine idles low, has a nice transition, and everything is generally stabilized, then you can either continue with this oil, or I prefer to switch to Amsoil System 2000 Racing Oil. You mix it at 50:1 and I use it with Premium Unleaded. This way, I can use the same gas for all of my engines (I mostly fly Brison). Don't mess with your needle valves until the engine has been pretty thoroughly broken in. I've had one where I never had to touch the needles even after break in! Either way, it's a lot easier than it is with glow engines.

Here's the Stearman with a Saito 180 installed.. The balance is pretty close without any ballast weight up front..I'm going with the bottom wing servo's /w/connecting rods that are with the kit..

Did you check the wing incidence?. If so how close to parallel were the wings?. When is the test flight. She sure is purdy.

I have not checked the incidence yet.. I just bolted it up per instructions and it appears to be close to flyable.. I have a laser incidence tool and I will check it out.. I don't have a fly date set yet.. soon though..

I ordered the GP Stearman and an OS120 w pump yesterday.
It's set to be delivered on Tuesday. Look immensely forward to receiving it.

If I find that I don't like the 1.20 in the Stearman, I have a G26 that I have run some 4 gallons of gas through and could fit in the plane.

Apart from the off-center hinge slots, have there been any other problems?

Crashland - the G26 is an excellent little motor.
It's somewhat heavy for the amount of power it outputs but the same applies for most gas motors if this size range.

Some people say that petrol (gas) engines come into their own in sizes of 50 cc and above because a glow engine of that size would be unpractical. I don't buy into that argument (or others)

I have the G26 in a 1/4 Taylorcraft and must say that it gets better and better with each tankfull I run through it.
I still run 1:32 oil mix but have switched to full synthetic. The oil I buy is what is used for high performance air cooled engies like motorcycle engines and racing engines.
The prop is an 18x6 wood prop.

I fly for 20 minutes at a time on approximately 500cc (1/2 litre) of petrol

So far, I haven't rouched the needles.

Carby hookup is somewhat tricky but I solved it by bolting an aileron bellcrank to a threaded hole that is in the crankcase straight below the throttle lever on the carby. I chose to do this rather than grind off the lever and replace it with an aftermarket unit. This has given me a very good acurate hookup.

You will love your engine.

The engine is installed in my Taylorcraft (the one in my avatar).
Unfortunately, I couldn't find a photo that shows the actual linkage but if you look at the photo, you can see the threaded hole straight above the carby. If you get a bellcrank (90deg) and bolt the pivot point to this hole, then you get a straight run from the horizontal arm down to the throttle lever with a short music wire. From memory - the length including the clevises was around 2.5 inches.

Does this make sense to you?

Since this is a Stearman thread, feel free to e-mail me offline and I'm happy to elaborate a bit on it.

Regards

Ari

I cant see it on your picture but I get the idea. I believe I have some of that stuff too, to do that.

Hurry up with the flight reports with those 26's!!!!
I'm thinking about getting one and would love to stick a gas engine in it!

I'm waiting on a flight report also with a G26 onboard before I decide which engine to buy. This would be my first gas project. I hope GP releases this ARF in a military version. The all yellow and red Navy version would be very nice.

I had one of those in Kyosho, I liked it but it was small and kinda squirly. But in all it flew great, you just had to be carefull. That is why I am wanting one of these bigger ones. I figure it will fly much better.

Let me ask this. What size tank are you guys gonna use with the gasser? Also would there be room for a smoke system?

So C'mon...G26 (or G23) flight reports! I'm tempted by this plane. I Have choices of saito 120, 150, or a G-23.
