i used standard 15 fuel and add i think 2 oz of 2 stroke oil to it and shook it up very well ran it twice until my jet went into a ditch and no a f plug not good i think i was using a mccoy number 3 or 8 i would have to look around and see

Is that 2s oil like you get for weedeaters? Or a special kind?

Would an O.S. A3 plug work?

rc airplane nut,
I live in Denver, CO. and have some experience with gas ducted fans at this altitude. I have not used the Rossi but I would only fly with the OS 91 or BVM engine at this altitude. I agree with most of the advice given. This past weekend was the Love-Aire jet rally in Ft. Collins, Co. and no gas ducted fans were present. There were 3-4 electrics and the rest (about 21) were turbine.

I have some ducted fan fuel left over and you can have it if you come to Denver. Just PM me.

Thanks for the offer, but that is too far. Dad can't afford to and won't want to go that far. Are you planning on going to any fly-ins any closer to here this summer? If you are maybe we could to meet at one of them.

How much does anyone think I could sell the rossi for? It looks like its in great shape, and I think it has only been run a few times.

I hate to say it - but selling any glow DF stuff is hard and you only get pennies on the dollar. $500 BVM engines can hardly be sold for $150. So you might get $50 - $100 for the Rossi. Like I said - It will fly OK on the .81 - but get an onboard glow system for it.

I think this might be a little more than you bargined for. There is really no way to skimp on a DF, you really have to pay attention to detail. They are expensive and maintenance intensive.

"It will fly OK on the .81 - but get an onboard glow system for it." The field elevation here is about 4,000ft so I think it will need more power, so I'm gonna get the O.S. .91 and sell the Rossi.

"I think this might be a little more than you bargined for. There is really no way to skimp on a DF, you really have to pay attention to detail. They are expensive and maintenance intensive." I know there is alot of work to do and it will take alot of money and that I have alot to learn about jets; but I know I can do it.

Good for you then.

Do you want a copy of the plans as well? I also have an OS.91 with only 1 flight and break in time. About 1 hour run, plus the proper pipe for it if you want. Maybe we can make a deal.

Right now I don't plan to attend any events closer to you, don't know of any happening. I don't have any experience with the Rossi 81 but it may work OK for you. My experience has been with the Top Gun F-15 and it flew OK at 14 lbs with the OS 91 at 5700ft elevation. My BVM T-33 flew better than the F-15 with the BVM 91.

I would recommend on board mixture control too.

"Do you want a copy of the plans as well?" Yes please.

" I also have an OS.91 with only 1 flight and break in time. About 1 hour run, plus the proper pipe for it if you want. Maybe we can make a deal." I would like it, but whether I can afford it or not at the moment depends on the deal.
About the pipe: there is a pipe in the plane already but I don't know whether or not it will work with the O.S. engine.

"I would recommend on board mixture control too." My radio has a switch for the flaps so I can't do that. Do D/F engines need tuning durring the flight or something, or is it because the engine is hard to get at?

I looked it up and the OS 91 requires a #2 tuned pipe, the Rossi 81 needs a #1 pipe. I can tell you have a #1 pipe.

While it's nice to have oil in your fuel - it is not required for the Byron fan - this is because the larger Byron fan loaded the engines more. They topped out at about 20,000 rpm. In the smaller Dynamax, turbax, and Viojet - they got upwards of 25,000 rpm and needed the extra oil. I never used an inflight mixture. It's nice to have though as the fans unload in flight and you could adj the mixture for maximum power - but Byrons arn't fast anyway.

I have your manual copied and will send it to you, I'm also going to copy some of the Byron info for you about pipes and such. Like I said - I can make you a deal on an engine, pipe, starter wand and I'll throw in my extra McCoy plugs. The engine mount will work for both the Rossi and the OS so you don't need a new mount.

There is one in Powell WY on the 4 and 5 of June Free on Friday $5 on Saturday. And I'm gonna be there.

skyhawknut, what kind of deal could you give me on the engine and things? About all I can afford until maybe the end of the June is an even trade.

I am tied up on June 4-5 so can't consider that meet. You need all the power you can get for take off at our altitude and the on board mixture allows you to safely peak it for take off and then be able to rich it up in the air if necesary.

Outside air temp is important too. You will notice better power on cooler days. I have two OS 91/s and a BVM 91 I will sell if any one is interested.

After talking to the rc pilots in this area I have changed my mind about glow; could someone please tell me what motor, esc, and batterys to get? I would love to get something that would work with the motor mount and fan that are in it already.

go to the EDF section of RCgroups. theres a few guys who have converted the byron stuff over to EDF already

Use a Rossi #8 plug, nothing else will live.

5% nitor with 20% oil will be the prime mixture for the old Rossi.

Pipe length is critical, I will check all my 30 year old literature for the correct length.

John Redman

My Feedback: (8)

Header length meassured from the center of the glow plug to the end of the header is 2-3/4".

Pipe length from the end of hte pipe (where it hooks up to the header) to the first part of where the exhaust returns is 10".

Basic silicone headers never lived with these. You will need a high temp header.

That should get you going.

I did - but it was sent back as they would not deliver to "resident". You never gave me a name.
PM me your address and name again and I will re-send it.

Electric conversion works good. I have 2.

Why not use Helicopter fuel that is 20%. It has more oil like the Wildcat Jet A fuel. If you can get the Wildcat I would use that.

Is that the byron fan in the pictures? If so, what motor is that and what esc and batterys are you using with it?
