Last week, a fellow flyer crashed nose down and totaled his plane. He threw everything in the trash. I MEAN EVERYTHING!

I recovered the engine and the best I can tell it is a Zenoah G38. The only problem that I have found is that the shaft is bent. I would like to either replace or straighten the shaft. Is there any companies out there that can do this repair?

If not, then what is the method to remove the prop hub? All the screws have been removed and I cannot remove the hub from the flywheel.

Any and all responses are welcomed!

Geistware, you are one lucky dude. You should have a good engine when it's fixed and it sure won't cost near what a new one does.

Everyone I fly with takes their junk home.

I made a spanner wrench to hook into one of the holes on the front of the flywheel. I then screw the hub off. It looks like you may have a later hub design than mine but I'm sure it works the same way. You will then need a gear puller to remove the flywheel from the shaft.

That was the plan. I have written two companies that are suppose to be able to repair this problem and no one has responded.

Just use a LONG bolt and screw it in to the hub, it will bottom against the crank. Keep turning and it will pop off the hub

Bennett says he will straighten them

Sorry, his web address is http://www.bennettbuilt.com/index.html

Milton: Thanks for the referral...However, no one inquired...I charge $40.00, plus shipping,.Guaranteed straight..Is this too much ???

I once had a G38 that I crashed and had Ralph at

rcignition.com straighten it and some other things done.

The engine was better than new when he sent it back and was quite reasonable also. This has been about three years ago so don't know what he charges now.

Bent Crankshaft
I just had Ralph straighten a G62 shaft for me. There is now no run out at full throttle. He did an outstanding job at a reasonable price.

You will get the best of the best, If you deal with Ralph.

how do you check the run out at full throttle?

I probably should have used a term like"wobble factor" rather than run out. Before I sent the G62 to Ralph, I ran the engine and looking from the side of the engine at the 22-10 Zinger, I noticed that the prop blades did not line up and appeared about 1/2 inch out of alignment. After Ralph straightened the shaft and using the same prop, the blades appeared to line up. This was an eyeball assement and not a scientific measurement. Sorry for any confusion my comments may have caused. I should have said"I bent it---Ralph straightened it---Good Job---Good Price"

Where can I contact Ralph?

I heard Ralph was going to be a way for a couple of weeks, but don't know for sure. If you can't get Him right away, keep trying. It will be worth it.

i sent my q-100 to ralf at rc ign it came back crooked as ****

Hey big mouth..Got any proof ? When did you ever send me a Q100, and if came back "crooked as ****" how come you paid for it and why no complaint ?
I have no record of any Lloyd Allen in my UPS addresses...

Hey Ralph,

Don't let this guy get to you. He's obviously a hoaxter who's trolling for trouble.
But what do we expect from a guy that starts his sentences with "i" and spells your name "ralf". :stupid:

Thanks, Randall, good point...Anyone who thinks they got a bad deal needs only to pick up the phone for a full refund..Very few takers in 16 years or so.....
How crooked is **** ?

I was waiting for you to get back to answer this, Ralph.

I thought, NO WAY did Ralph send Him a back a bent shaft.

wats your # dear randal

Wouldn't you want the phone no. of Ralph, whom allegedly did the deed on your shaft?

BTW, I too would like to know too how crooked is ****?

My number is 928 (was 520) 635 2425, clearly printed on the top of the receipt..You could send the alleged crooked engine back to make it right or tell me when this happened so I can look it up in my records..I have never sent ANY engine back with more than .002 runout measured at the outside of the prop hub....

By way of comparison, a human hair ( my arm) measures .002 with my Swiss Etalon micrometer...
An eyeball that can see that well belongs in the Guiness Book of Records..

I can attest that Ralph is a stand up guy who is more than equatable in his dealings with people.

I gotta vote for RC on this one.
I send him all the "really fun" cranks
