Hey bigbird hit the roto link, top left above the list of engines click on the on the union jack, you will get a english roto page. Looks like the 85 fs is a gas engine uses 26-28 inch prop. Enjoy

Bigbird, you have a great work going on that stearman, really is a super proyect.
The roto engines are made in Czech republic, and yes, they run on gas. Don´t know where you can find them on EEUU, RCShowcase was the dealer, but they went out of bussines. There is a RCU member selling a couple of them for about $500 USD I think.
The 35 is a little to heavy to balance the stearman without tail weight. So I can tray to put the batts on the tail, or maybe install 2 elevator servos. It won´t be pretty, but it will work.
Well any suggestion will be aprecciated.

Vacaman, thanks for the complements again. I went to the sight and clicked on the british flag for english language. Everything seemed to be there but the prices. They even listed the countries they are sold in. Some listed have
'looking for dealers in this country' where there are none.
I didn't realize that the '35' is so large. Is it equivilent to the G-38 that Zenoa sells? If so, that is way too much for this Stearman! I fly mine with a G-23! It is a little more than scale like power but if you don't fly it scale, you can get in trouble real quick.
I like very much the look of this Roto engine but for half the price I can get an equivilent engine. The twin cylinder is quite appealing and better sounding too but in the interest of the budget I must sacrifice the sound!
As far as balance on your plane, there are many ways to approach it but the most reasonable one seems to be to replace the engine with one that is not so heavy. Adding weight to the tail is a good idea as long as you don't have to add too much.
The 'tail heavy' formula is; for every ounce the plane is tail heavy you must add four (4) ounces to the nose.
So, the opposite is true for a nose heavy plane. You must add One ounce to the tail for every four ounces in the nose that is over.
Balance the plane slightly (slightly) nose down with no fuel in the tank, this will give the plane some penetration abilities especially in the wind and with the massive drag of the bipe configuration.
Also, learn to fly with a couple of clicks of down trimmed in so that the plane will naturally try to come to the ground on it's own. Again just slightly. This will keep the plane in a forward decending attitude on a dead stick landing without having to contrate on keeping the plane flying and landing at the same time.
This will also help in the performance of the plane coming out of turns, loops and inverted flight. In these instinces you don't have to put as much down in them to accomplish the manouver making is smooth and not so much of a 'porpousing' or nose rise at the end of each manouver.
This is especially effective on landings. If the plane is naturally coming to the ground, all you have to do is pull back on the stick enough to touch down and then when you let off of the stick just as the main wheels touch the runway, it will level off and then the tail will settle to the ground completing a 'wheel landing'!
Just learn to fly with the down trim in at all times. It will become second nature and you will be amazed at the results.
Just try it and let me know how you do.
Adios Amigo. Maniana. bird.
I'll be out of the house for a bit.

Is a saito FG36 to much for this plane? or do i have to go for FG30?

The 30 should be plenty. Mine flies fine with a 170 3 cylinder with a 16 x 8 prop.

duplicate post

Royalevo, the 30 would be ok but if you have the 36 already,after all it is only 6cc more .I am fighting on which of two motors i have to put in mine, i have a 45cc and 26cc both crrc motors.I am going to make a wing walker stand for barbie and a loose fitting blouse so it falls off during flight just to have some fun at the field lol lol.



BIGACO

Thanks for reply, think i will go for the FG36 with keleo pitts muffler. Probably i do not need all that power but think it is better to have a larger motor than carrying lead in front.

The only problem, that I see, with a big engine on the stearman is vibration. My engine weight the same as a da50, and I am just moving the batts to correct the cg, that´s all. The stearman doesn´t feel heavy on the air, and the good thing is that with more power I can have same real fun or just slow down and make some scale type flying and have even more fun.
When I bought my stearman I installed a os 120 four stroker. The engine was at high throttle almost all the time and I wasn´t able to make all the maneuvers that the plane was capable of (Maybe my fault) but now with the bigger engine I found it a lot more fun to fly, and I don´t consider that is overpowered for what I like to do.

I'm glad to here about the DA 50 being about right for weight. I have to pick mine up from the LHS they said it all arived today. I ordered everything through them accept the motor and that was a mistake. I have a smoke pump coming for it and a aerovate 45 cc engine. The engine I ordered through KMP and my service has been poor. Only got part of the engine in the box and KMP say's the rest of the parts need to come from China. I phoned Henry (piston) at aerovate engines and he says he brings all aerovates into the country, but not the one I have of course so he is looking into it. What gas engines do they make in north america? Do they provide good service? Can't wait to get this Steerman in the air, it's a beauty.

I have a dl50cc and a smoke system. I used a lot of baking soda and ca glue to beef up on the inside of the firewall. I have just added two washers per motor mount, on the left side to give it more right thrust. Before it would make a hard hook to the left. I'm using a 20"X 10" prop. That is the lagest dia. that I can use, and I'm still maxed on the rpm. I used li/po for the engine 7.4 volt and 11.1 for the rec. with voltage regulators. I think I'm still a little tail heavy. I had to added lead to the cowl. When I get it the way I want it, I might move a battery or two under the gas tank. I don't like using lead. It will still fly unlimited vertical with all the extras. Good luck

I'm the same way when it comes to adding lead, I would much sooner put in a bigger mill then you kinda have a hot rod if you need it. For this plane though with the added smoke system it should be about right. I'm going to the city tommorrow to pick up my stearman and of course a whole pile of other goodies. The closest hobby shop for me is a 2 hr drive. I usually make it worth while when I go, and when I leave they call me sir and get the door for me LOL. This will be my first gasser, and first smoke system, so it is an interesting build for me. By the time I get it built, it will be 30 below here so it will not be flown till spring.

I love mine. It is my first gasser and smoke and 2.4 I love to smoke!! We go to Canada every few years. Last year we drove to Calgary and then up to Edmonton. Never made it to Saskatchewan. Someday I hope. Must be a lot of open space to fly. Not much room in LA county to fly. Stay warm and take your time. You will love the stearman!

Lots of open space here Ron. I live on a farm and have my own airstrip in the pasture so if I want to fly, I can be in the air in 5 minutes if I want. The bad thing here is there is not many people around that are in the hobby, so I don't get to watch many other people fly. I have my private pilots license but have not flown a full size plane for about 12 years now. To many hobbies and not enough gold or time to do them all. Got all my gear home from the LHS and just had time to open the kit and check for damage. everything looks great. Also got the missing parts for my aerovate 45 cc, that were shipped directly from China. I have everything I need now.

BBRRRR. it's 32 below here this morning. I guess flying is out for today. I have most of my steerman together. Had to cut a hole in the fire wall and build a box inside for the carb on the aerovate 45cc. Also made a stainless steel exhaust to wrap around and put 4 pipes out the cowl. Just working on radio gear now and the smoke system. No hurry on this one, it will be like this outside for a couple more months at least. Happy building everyone.

Oh dear GOD, how can it be -32 (c or F) anywhere!! Move south man!!! Your push rod is gonna freeze up!

LOL moving south sounds like a good idea when it's this cold out. It's -33 C here this morning. Add a little wind and you need to dress up like a polar bear to go to work. Here are some pic's of my stearman.

Les, Did you TIG weld that muffler? You did a great job! I like the way you did the smoke oil tube going in the muffler with the small holes. You need to get a snow ski set for your plane. Then you can fly more. Would that engine run at 32 deg. below? It has been 45 deg. at night and I thought that was cold. Stay warm and good luck

Capt. a TIG would be the answer, but I did it with stick and 1/16 rods at 45 amps, the material is 18 guage accept for where it bolts onto the engine it is triple thick there. It was a painful experience to say the least but I am happy with the muffler. I ordered a tip drill set for cleaning torch tips holes out and it has very small drill bits that you just use by hand. That brass tube is only 1/8 so you get some idea how small those holes are.

That Aerovate 45cc looks great in your plane...I bought one from Henry 9 months ago and have been running it in a gp 27% caps.....best motor I have ever owned...Just give it a chance to get broken in.....2-3 gallons

I am happy to here these motors are good, it's my first one. It must pull the cap around pretty good. I have the cap also but I put the OS 160 in it and it's alot of fun to fly. Do you have the stearman as well? If so how does it compare to flying the Cap 232.

I swear I thought Les Nessman could fly !

To good to pass on that, sorry

Hi all! Considering an electric conversion on this plane. Is there easy access to the front of the plane for large lipos? I've read the manual and I'm not sure there is.

[:@]AGH!!!! dont ruin a lovely aeroplane, a stearman needs noise, smoke, character that will be gone by fitting something that is for flying bits of foam![:@]

Best void for batteries is behind the firewall, where the fuel tank goes. Only access is through the lower wing saddle. Besides, I have to second the opinion of Xairflyer (above).
