Nitro Newbie needs help
I was given an old Shuttle ZXX circa 1995. Practicing with XTR, now at the point to give it a try. This morning I attempted to start it up and maybe get it light on the skids, but it would not fire after 4 hours of trying

I brought the heli into the LHS for advice, but got mainly shrugs (this was a few weeks ago). I picked up a gallon of 15% heli fuel, a 1 cell glow starter, and a new glow plug - same size as the old one (I tried them both).

I admit I do not know the proper starting procedure. Here is what I did:

1. Small amount of fuel, enough to cover the clunk in the smaller tank.
2. Turn on Tx
3. Turn on Rx
4. Tx throttle down all the way, trim to 50%
5. Connect glow ignitor to remote wire
6. Turn over engine with electric starter and shaft.
7. Raise the throttle to 50% at times during the cranking (I was afraid to give me more)
8. Turn the needle valve while cranking. It was initially set 1.5 turns open. I tried everything from closed to 6 or 7 turns open.

It never sounded like it was going to start. The sound did change as the throttle setting varied.

I saw fuel in the line leading to the carb. After a while fuel dripped from the exhaust.

I removed the plug and tested it on the ignitor, OK. I attached the plug to the remote wire and grounded it to one of the engine mounting bolts, and it glowed. I turned over the engine with the plug removed, but no fuel came out.

I am not sure what engine this is. The heli has very low hours, probably has the original blades. It is clean and in very good condition, ie. it is not a beater.

I resoldered the connections on the remote glow plug wire, and checked with a meter, all looked fine.

What did I do wrong? Wrong fuel? Not enough throttle?

Also, what happens when the enging starts running? Is there a certain RPM where the blades start spinning? I was very concerned to give too much throttle.

Go easy on me

People who buy used heli knows something about the hobby.
For a beginner getting into this hobby should buy NEW equipment.

You are wasting your time and money trying to resucitate a dinosaur.

I paid $0.00 for the helicopter. The only things I needed were fuel and a glow ignitor. The one I had from my nitro airplane days was weak, and I didn't want that to be the cause of starting problems.

I have my eye on a T-Rex SE, but wanted to try to fly the Shuttle to see if I was any good at it. Much cheaper to buy a gallon of fuel than a whole new heli setup.

I agree with Raffy, you are doing nothing but wasting your time and money with outdated equipment, do your self a favor save your money
and invest in all new from ground up new equipment, I'm sure you will be happy with a new 30 size machine that you can trust.

Good luck

Do you have help from anyone that knows about nitro heli's?
If you are a begginer you need help. I don't care if you have New equipment Or Old stuff,,you will at first have no clue. You can have just as much trouble with expensive new stuff as old with no knowlege . Have you ever flown a rc heli for real? Or setup and flown either an electric or nitro heli before? I'm not being rude because everyone of us on this list has been there and I feel your pain if that is the case. At times in the beggining it seems overwhelming the amount of Crap you have to be on top of to make a nitro heli hover without burning out the motor or crashing. Get some help to setup your antique and at least find out in capable hands if she is airworthy. Hopefully it will work for a time if setup correctly,,but if you are shooting in the dark you will be defeated!! I do not know about your heli and maybe no one in your area does either but a good heli pilot could make it work for you. Get a Guru to help.
Setup is everything, All my heli's can fly far better than I can pilot them

It works!

I suspected there was not enough fuel last time. This time I filled the tanks. Immediately I could tell there was more resistance to the starter motor. Less than 10 seconds of cranking, and she fired up!

Immediately I brought the throttle stick down, to make sure I had control, and it would shut the engine. Indeed, it did.

Started again, then stepped back. Give more throttle, spinning up nicely. Watching the disk, I confirmed all controls were operating in the correct directions.

After a few minutes of this, I made her light on her feet. Rudder control was good, tail holding.

A minute later, what the heck might as well, up she goes! Well, up about two inches

And... Hover! XTR really paid off, my thumbs just did their thing. I hovered like this for a bit, then went a little higher, maybe 6 inches.

No drama, back on the ground, grinning ear to ear
