Hey guys id like to put an O.S. BGX-1 in my monocoupe, i picked up this motor with a bisson side mount pitts and was curious if anyone knows if this motor mounted sideways would create too much off to the side imbalance issues, I know that i might be able to put lead in one of the wingtips to offset this but was hoping any input about what id like to do can be shared with me on this before i start any cuttin n drilling.
Thanks.
Louis

But would you have to cut a big hole in the side of the cowl for the head? Other issues might be cooling, weight and torque.

Thanks Mr. Hellcat for the info. Your Monocoupe looks terrific. I've gone back through the thread and read all I could find. Now the questions will really start. I hope you don't mind.

I see you mounted your servos in the tail, but you didn't know if the 18" extensions would work. How did that work out?

Did you use the stock fuel tank?

Are you still using the Xoar 18 x 8 prop you started with?

What all other gear did you use? (servos, receiver battery, ignition battery, etc).

Also, if you happen to have a picture of the engine install, I'd love to see it.

This would be my first gasser. I have quite a few 90 size nitro planes, but think there may be a big sale this spring. I'll be using a JR 9303 on 2.4 gig.

Thanks, Jim

Status: offline 		Been kind of quiet here lately, so thought I'd post a couple of pics of my engine and "instrument panel" installations.
Just about done. Final radio setup and balance are all that are left once I get the Sullivan Glow Driver working....
Engine is OS160 w/ OS predrilled aluminum mount and Slimline Pitts-style muffler. As you'll see, I had to put almost an inch of spacer behind the engine mount to get the firewall/prop distance correct, but once I did that, things lined up great. Made up a panel out of 1/16" ply and installed the switch/charger and Sullivan panel in there. It's a little bit cramped, but I can get in there to work things out. I'm toying w/ the idea of using a couple of rare earth magnets to hold on the top panel but probably'll just stay w/ screws.
Having a bit of trouble w/ the Sullivan Glow Driver. You hook the throttle servo into the Sullivan panel, then hook the panel throttle wire to the receiver. Then install the glow plug connector to the plug, and atttach the ground wire (which as supplied won't even accommodate a 4-40 bolt, let alone one larger, so I had to replace it) then plug into a separate battery. As it now stands, the throttle servo works fine, but I don't have any "fire". Any ideas before I call Sullivan?
Thanks
One of these days the weather here's gonna be good enough to fly!

I've never delt with one (Sullivan), but there must be some programming that needs to be done so it knows when to turn on the glow at a certain throttle servo position.
What servos are you using? I'm still thinking about this plane with a Brillelli 36 gasser.

Status: offline 		I'm using 5 JR 126MG Sport servos, two for ailrerons, two for elevator, one for rudder and a standard ST47 for throttle. Receiver battery is 2400 mAh, 4.8 volts. receiver is JR PCM 7Ch PCM Scanselect.
There is a programming step for the Sullivan to align it w/ throttle position. First step is to turn on the switch and according to the instructions one of the LEDs'll flash. Nothing. Plus you set throttle/glow ppoints by using lights. Nothing there either. As I said, thete's no "fire", no current. Plug's good and plenty of charge on a brand new battery.

Does the throttle servo work? Or it there no action there either?
Tnx for the servo info.
