I have a question about the FG 36 that I can't find addressed in the manual. Is the typical fuel tank pick up line large enough to supply fuel to the carb. The line on the carb itself is larger than the pick up line that comes with the fuel tank. I think the standard line is 1/8 inch tubing but it looks like the carb fuel barb is about 3/16. Should I put a larger pick up line and clunk line on the tank or will the standard clunk and fuel line supply enough fuel?

Did you get an answer to this?

The engine's fuel consumption volume doesn't warrant larger line

Thank You, I came to that conclussion after I thought about it, the gas engines consume much less gas than glow engines use so I didn't think the larger line was needed. I appreciate your taking the time to answer though, I'm sure I'm not the first to come across these larger fittings and think I needed larger line.

Very true

I've come across a new problem, the elevator connector is next to the receiver port for the electronic ignition port and I'm getting a lot of feedback to the servos. The ignition has an optic isolator that I thought would eliminate the jittering servos but it hasn't. The ignition is only affecting the elevator. I may have to pop for digital servos on the elevator. Either that or the electronic switch I bought isn't really an optic isolating unit. The feedback is speed related as the servos stay neutral until I take the RPM's up past half throttle, then it goes to full up. It's keeping me grounded while I break in the engine at least.

since it is only one servo it could be a vibration problem. Try a different servo.

Nah, it's two servos on the elevator on one circuit, it is definately rf signals coming from the EI. I haven't hooked up the flap circuit yet and that is the connection on the other side of the pins so they may also be responding. I think it is only the circuit directly next to the EI connection.

Why is your EI connected to the receiver?

TravelairR

My Feedback: (7)

EI is connected to receiver so that I have a radio controlled shut off. My transmitter, Spektrum DX-7, doesn't have a throttle cut button, so the only control I have in case of emergency is transmitter controlled shut off.

Most people just pull the throttle trim all the way back to shut them off

TravelairR

My Feedback: (7)

Yes sir, that's one way to do it but if you have a servo fail or a linkage come disconnected a gasoline engine can fly a long time before it runs out of gas and it may not run out where you can easily get back to the field. It is much better to have a way to shut off the ignition someplace convenient. You know, it's like carrying a spare tire, you may never need it but if you do you don't want to not have it with you, it's the same thing with emergency shut off's, if you never need it fine, but if you do it may save your plane.

Sometimes these extra nice to have goodies can be more trouble than they are worth.<div>

That's one way to look at it. I may have to do without the switch but I think it is a worthwhile addition and will work at making it work. I'm sure not trying to tell everyone they need a switch like this, it's just something that has worked for me and I've witnessed enough incidents to know it has it's benefits. Thanks for your input though, it's better to hear others opinions than just be ignored.

I know what you are talking about as far as run-away engines go. Been there and done that. Was at a lower throttle with no throttle control. The plane flew for 55 min before running out. It was the third flight on the batteries and I was afraid the flight batteries would give out but they didn't.

TravelairR

My Feedback: (7)

yep, I've seen planes wrecked just because of stuck throttles and no shut off, that's why I want to make this electronic switch work. If I never need it then I'm happy but if I do need it I'll be really happy I have it. Today I ran my ignition battery down to far and the engine quit but it is on my Rearwin Speedster and I floated her in for a safe landing.

Hello, Gentleman. A friend of mine here in Brasil has one Fg 36 and he`s trying to figure out what is it`s working temp...does anyone has a clue about it??

Tks a lot.

Why not contact the optoisolator's designer, if they are still available? Sorry if you thought of this earlier.

The only working temp that truly matters is an Exhaust Gas Temperature reading which requires a thermocouple sensing the exhaust stream. Those measuring IR radiation are pretty much useless.

They do not seem to run that much hotter than a Saito 220.
