    Status: online     		They are in stock and mine is on the way. I've been flying Helicopters for the most part the last three years but this plane has me all excited about flying airplanes again. Now I need to decide on an engine. I'm thinking about an OS 1.20 pump, YS 1.40 sport, or a Enya 1.55. It will be mounted inverted. I've been leaning towards the Enya but not sure how well she idles without constant glow heat at low RPMs. I could put an onboard glow igniter on her but would rather not if I can get away with it.

    And, they provide a neat little plywood box to fasten to the motor mount to put the 18 ounces of lead into, which was needed to balance the plane.

    It's all there in black and white, right in the manual.

    At least they told you to plan for it, not like some other manufacturers, who never mention that you have to add a ton of weight to balance your completed model.

    The Enya, probably heavier than the OS, will require less lead.

    The completed plane, however, reportedly weighed less than 14 pounds dry.

    Small...like in 50cc?!!

    Actually, I wonder if a G-38 (have it on hand) work. I think if someone chose to go with a four cycle, the Saito 170 R3 makes a better choice than a 1.20 single.

    When you get it, could you measure the cowl diameter, please? I'm thinking of getting one of these, but would like to go with a gas engine, and want to see what may fit without cutting holes.

    Status: offline     		Just got mine from Tower on Saturday. I agree with the prior post that a G38 is too much engine. This is not a very big airframe and it looks like a G26 will be the appropriate engine in power, weight, and size. I've got a B&B G26 that I'm going to use in the plane and I'll post some pictures of the plane with the engine as soon as my wife gets back with my camera. The quality seems first rate, and it has some interesting landing gear. It's not nearly as large as I was expecting, but at least it should fly well without having to spend huge $$ on servos. This is no 3D machine anyways, so I'm expecting it to be a great flier on a G26 and some mid-range servos. I'm going to go with the two aileron servos and slave the second set of ailerons off the first as in the real planes. It even comes with pilots! Not bad for the price, although I would have liked it a bit larger with easier to remove/install wings.

    Status: offline     		My dad is flying a Pica Waco thats the same size as the Stearman. It has a os 120pumped in it. It flyies very scale like using altitude to gain the airspeed. He's taking the 120 out for another model he's building. Looks like a Saito 150 will be taking it's place. It's awesome being able to make it look real in the air. Not to many people can make them look scale gotta fly them full throttle all the time..
    Later,
    Frank
