Craig:

Thanks, but there is no need to dig out the info. My Stearman is done and been flying for a month.

I used the control horn settings noted way back in this thread. Asking for the addendum location was more out of curiosity than anything. It's too bad that the the RC report and this thread show the correct settings but Great Planes doesn't feel that they have to make note of it in their build manual or addendums.

This plane has become one of my favorites.

hey guys,flew my stearman on tues.for the frist time and wow!!!!!loved it and the rest of the crowd loved also pics of low fly-bys and movies were taken everybody went crazy.I have a g-26 with a 18x6w and getting 7,000rpm,the engine has about 3gals through it should I ba getting more rpms?
thanks Fred

Ed, Thank you so much for your reply on the CG issue your idea sounds great and I amjust about to go to the w/shop to try it out. Ant ideas on the other issues I raised in post 909
I am particularly concerned with the aileron issue or should I call GP support? I am now really worried as I;ve never flown a plane this big and heavy and going through the different posts there seems alot of issues I never faced before. Thanks again for you help. I think I got this right, now

Hi,
I decided to use the 4 servos on the ailerons on my Stearman but I’m not to clear on how to connect them to the receiver.
Are 2 separate channels used one for the top wing and another for the bottom; then mixed together with the radio. Or are both top and bottom connected to one channel using several “Y� connectors in a series?
In another post in this thread I read that this guy installed a “Y� connector inside the wing before the wing halves were clued together. The idea is that you end up with only one lead wire coming out of the top wing, a cleaner set up. It’s a cool idea and I’m going to try it.
It will be greatly appreciated if someone can respond to the above question.
Happy Flying!

Aerosman,
I setup my Stearman with aileron slave struts but I have a Pitts with 4 aileron servos and have no Y connections (2 servos sharing the same signal), rather the servos from each wing are wired to a Multiplex type 6-pin connector and plugged into a harness that goes to the rx. That is, each servo has its own signal so I have complete freedom of mixing on my radio. I have a fondness for those 6-pin connectors for all types of wing harnesses.
They are refered to as Graupner Speed 400 connectors here: http://www.hobby-lobby.com/connectors.htm This setup is simply one plug in for each wing.
The Stearman with the aileron rod admittedly has some geometry puzzles to contend with, but works very well once you get it right and looks cool, too.

Podo,
Nice Plane![sm=wink_smile.gif]
Thanks for the info. I'll look into it.
Not having any experience with bi-planes I have been researching the pro and cons of using 2 or 4 servos. Both ways seem to be expectable for a number of different reasons. So having to make a decision I went with the 4 hoping to have more control, also I’ve seem that a lot of people have had trouble trying to adjust the slave struts. I guess I’ll learn if I made the right decision or not.
What type of material did you use for the flying wires?
Anyway thanks again for the advice.
Happy Flying!

Podo,
I agree your steerman looks great! I have been wanting to add flying wires to mine also. The recommened method in the manual
is to use elastic material available at craft stores. I have not been able to find any that seems to be the right diameter to me.
All the stuff I have found seems to be to small.
Yours look great, what did you use?
Craig

Aerosman and KCCraig ,
I used 1/16" metalized elastic cord that's available at Jo-Ann Fabrics which is a chain here in the midwest. That's the only place I found it. Tried a couple other places including w-mart. It's called StretchRite Metallic Elastic Cord. Look in the beading section of your local craft store. The cord is just plastic so there's no radio problems and it looks a lot more like the rigid steel "wires" on the real plane than the black skinny stuff recommended in the instructions.
Pete

Craig:

Here's another source for your flying wires. These look a little goldish in the picture but they are definitely Silver in real life. Good scale look as far as the diameter.

Got these at "Michaels" a craft shop chain here in Michigan.

I just purchased a Stearman. I also decided to try a 3W-28 with a Johnson Pitts muffler. Does anyone have a sullivan skywriter smoke system in ther stearman? I wonder if it would make the wing loading to high? Please anyone respond if they have?-J

I have the TME smoke system in mine with a 10oz smoke tank. No problem at all with the added weight.
Running a Saito 150 with a 16x8 APC prop.

edkoz,
I'm also going to use a Saito 150 in mine. Were did you mount the pump and tank. What muffler do you use?
Also how's that 16x8 prop working out for you?
Thanks and Happy Flying!

Aerosman:

I've attached pics showing the tank and battery pack locations. I'm running a 6 volt pack for the radio gear and a 5 volt pack for the smoke system. Also a pic of the smoke oil feed to the header. My brother has the PT17 and put a preheater on his but took it off since it didn't make a difference. All we did was to tap a hole in the header pipe to fit an old needle valve to use for the smoke oil delivery ... works great. No need to go with a special muffler($150). The four stroke is never going to smoke as good as a gas engine but this setup does a decent job.

Happy with the 16x8, I may try a 18x6 just for the hell of it.

here is a link to some Stearman photos that may interest some of you.
take note on the spinner size used on a few of these..............it's larger than our kit spinner in scale size.

I had an interesting experience with Great Planes to share. Like most of us with the Super Stearman I had a lot of wrinkles to iron out. In doing so I noticed that the Monokote at the bottom of the fuselage was cracked and one of the ribs was broken. I tried fixing it and it didn’t come out well. So I said f… it and I called GP. I was lucky to get a very nice customer service rep by the name of Susie. After a pleasant conversation she said to just send in the fuselage with the receipt and they would send me one back.
So the next day I spent a couple hours cruising dumpsters in the local industrial parks for the right size box. Finally I found one that was close to the size I needed. The next day I spent about an hour modifying the box. By the time I was finished you could have sent eggs in it, it was that strong.
Then I had to call GP back because I had misplaced the receipt. I got Susie again and explained the problem. She then told me to hold while she spoke to her supervisor. She came back with even better news then I expected. She said that I didn’t have to send in the old fus and that they would send me a new one at no charge. By then I was hooked she was so nice I told her that even if they had refused my request, getting a negative response from such a nice person would have been easier to except. Susie at GP made my day. I wish all my problems were that easy to fix. Well hopefully it will be here soon and I can get my Stearman finished. I can’t wait to fly it.
Happy Flying!

i fly mine on a saito 100. its purposly underpowered so i can practice to with marginal power. i fly mostly 1/5 warbirds so its good training. once in the air the 100 is plenty of power and loops from level flight are fine

Does anyone have detailed pictures of how they intsalled their G26? I've been looking for shots of how the fuel lines were run and the throttle linkage. I ordered the EZ link from Zenoah that replaces the stock cam on the throttle shaft. It was supposed to be "easy" to install. Far from it! I had to cut off the old cam, grind down the new linkage arm, cut the idle adjust portion of the cover casting off just to get it to fit. Now I don't know if I can get clearance for the end of a ball link in the linkage arm! Needless to say it's been frustrating...maybe I've made it harder than it should be. Also, the motor came with a plastic "ram" intake and a different style plastic insulator for installing between the carb and engine block. What is that for?

Any help with illustrations would be great!

Thanks!

Gentlemen, here's the only way to power this aircraft:

Here's 4 more views of Saito 170 installation!

Guys, I've got this plane and have been flying it for a couple of years using a Saito 170 R3 for power. It is the ULTIMATE combination! You will forget all about the cost of this engine the first time you start it. The performance is on par with what this airplane is, a scale bipe. I have also seen several of these with the G26 engine and they fly about the same as mine, BUT, the sound of the radial makes the plane!

I just got one of these Stearmans, still in the box. Waiting till I move in two weeks so that I'll have a good place to assemble it. I couldn't resist the interesting technology behind the RCV SP series engines and found a very slightly used 1.20 to put in it. I figure the 18 to 20" prop this engine will swing will make it look about right and the massive torque they're supposed to have should make this thing very scale in speed. We shall see.

Kurt

rcten,

Can you supply details of how you mounted the R170? I've got one just hanging around with the same exhaust ring. It looks like you used a plywood plate covered with CF. I was going to use a g26 until I saw your pics! TIA

FB

FreeBird, basicly the plywood plate allowed me to utilize the exsisting engine mount holes and blind nuts, it also gave the distance from firewall to back of spinner clearance. The problem with using the 170 mount spacing is in the support arrangement for firewall and accessability to properly attach blind nuts. I also placed the throttle servo below eng. on firewall, this not only made linkage simple, it also helped with balance.
Speaking of which, balance that is, by placing 1400 4.8 sub-c ignition pack by the fuel trank and 7.2 AA nimh behind tank, the plane balanced perfectly with no additional weight.

RCTEN

Anybody used a FPE 1.3 on the Stearman? Wonder if it is enough muscle?
