I just set the throttle hold to cut the engine, if you’re near enough to operate the throttle kill switch then you can just turn the choke on and that will kill the engine.

I only like to fly gassed up

..any way you can fix up a relay or a 42percent killswitch to ground or cut the ignition? It's what I've got on my PUH's as additional safety if the throttle servo jams open in flight.
..it also means that wimps like me who haven;t got the bottle for elective autos can cut the engine quicker for plug reading (yeah i know it's not as meaningful as cutting from full power but I've done enough rebuilds now)

Ok almost ready for a Maiden flight I just decided that the heli was a mess so I cleaned it up as you can see from the pics before. I rerouted the Fuel lines and also a little wire cleanup. Enjoy

This Kit is designed for the RC version of the Zenoah because of its built in fan shroud. But He also sells a Kit for the PUH motors. Hope this answers your question.

Gill, the engine modifiers do the RC too. Something to think about later as an upgrade. It might not be needed other than to squeeze out a little more power because the RC engine runs smoother than the PUH out of the box.

Nice job on the build.

Thank you CNCJunkie

Is it true that it takes 2 gallons to properly break the engine in because I figure I can get about 8 tanks on a gallon and two gallons is 16. I figure the fuel would last around 30 min so that would equal about 8 hrs for break in am I right or did i miss something.

are there provisions for using a removable pull starter in the conversion bottom plate?

does anyone if you can buy the align kit with the gasser coversion kit or do you have to buy them separately?

thanks

1 gallon with non synthetic oil is the norm, but it certainly won't hurt if you wanted to make it 2. Keep your flights down to 15 minutes, or you're going to get tired. Break-in is a bit tedious, but it will be the best for your engine to take it easy for that first gal or 2.

One more thing. Do I need to take the carb return spring off to make it not a strain on my servo?

Thanks

Carb Spring

Just stretch it out a little. Should not hurt your servo , and will help if you have a failure.

Don't remove the spring. there are tension adjustment holes in the plate which is part of the throttle shaft. You can move the spring hook to one of lower tension.

If you remove the spring, the throttle shaft bore can wear prematurely.

Since you are breaking in your engine it will be running rich and you will find that you will use a lot more gas than what you expect once it is broken in and running like you want it to.

On one of these post it talks about recommended break in procedures.

The basics are that you want to start out low rpm and low or no load. Then after 5 or 10 minutes shut it down let it cool to ambient temp then go again and each time add a little rpm and load. Try to keep the overall enginie rpm in the lower range for that engine For example on my Wally 270 I started out at 10500 then, 11000 then, 11500 then, 12000 and finally 12500 to 13000. Wally ran the engine for 1 gallon then I ran it break in for 2 more. On my other TRM motors I have run them for 1 gallon as described above then went to synthetic and around 12500 rpm.

You might also want to monitor the temps, see the threads here on that topic. IMHO with temps in the 30 to 50's engine temp after run should probably be kept under 230. Mine has been as low as 130 up to 170, but with the Wally engine and fan it is running cooler than my other ones. You will find that these are guidelines and your may or probably will vary.

Ok so i got the maiden flight done and video taped it but the dvd disc in the camera got corrupted so i lost the maiden flight video. so I will just do another flight which will be even better. I got the motor running no problem. I should have let it idle more but i didnt. also we live where its like 80F and no cold harsh weather. I checked the tempurature on the exhaust side on the fins above the exhaust port and got about 250F is that ok (normal) just wondering. Its Loud but thats ok ill get a new muffler one of these days.

Thanks for your patience and ill get a video asap

Nice pictures Gill, I’m looking forward to the video.
I would say 250F = 121 degrees Celsius on the exhaust side is OK considering the outside temp.

I only like to fly gassed up
