Well I have a very slightly used Meteob .15 FAI engine and was thinking of building a Geodetic 585 Galaxy for it. I have no idea what the performance is on these engines. Any advice and running experience would be appreciated.

“I have no idea what the performance is on these engines.”
Well, one sure way to find out, is to put it on the Galaxy!!! 🙂 🙂 🙂03/30/2008 at 11:08 am #45601AnonymousInactive
Hey Scott how about a picture of the engine. If it is what I think it is then throw it back in the draw, a power house it ain’t; oh and it is a Meteor 15 of Russian origin.

I believe the Meteor is a seudo Super Tigre copy, the one I have, a glow model, is weak in the compression dept though brand new. I have never tried to run it.05/15/2008 at 1:50 pm #45603
Well experts, I went home last night and took some pictures of the engine in question. On the side of the engine is “Meteop”. I looked real hard for the tail on the “P” in order to make it an”R” put none was found. Let me know what you all think after reviewing the pictures.

The Russian P is equivalent to the English R.
As far as the engine…from what I’ve read, most are as described above, but I’d run it and see if a good one snuck out of the factory. Nothing to lose since it’s not a collector’s item, yet.

Randy was right, it’s a Super Tigre clone.
In this case the G.20/15 model which was much loved in its day. Of all the Super Tigres my Dad ever had, his one G20 was better than all the G15’s.
I’ve never seen inside a copy, but if it really is pretty much the same as a genuine Super Tigre, then it might respond to a decent set of bearings, and some basic gas path polishing.

I recently purchased a diesel Meteor from Carlson. It too felt weak on compression but I decided to try to run it anyway. It was a bear to get running the first time, but turns out to be a strong runner turning an 8-4 Master Airscrew (black) around 13,000. I didn’t get a good reading because I didn’t want to let it honk to hard until I had some time on it. Afterward I was wiping it off and noticed that the front bearing outter race was turning with the shaft. So, I disassenbled it and it was just filthy inside. All manner of chips and swarf in there and apparently a chip had lodged in the bearing causing it to spin. There was allot of endplay in the shaft and the front bearing moved in and out, so I was going to shim that anyway. Now I’m going to put a good set of bearings in it and polish the ports a bit and see what it will do. I think it might even be respectable with a little work. If so, I’ll give the glow Meteor the same treatment. The bearing fit on the front bearing is about .001 loose, a bearing spring washer behind it should make it acceptable.
I also had to choke it down a little with a balsa shim beside the spray bar to get it to draw, it started quite easily after that. I plan on running it on a bladder anyway so I won’t have to make a venturi for it.
So if you decide to run your glow model, check it over inside and out, luckily I didn’t do any visible damage.05/21/2008 at 1:35 pm #45607
Randy, thanks for the heads up. I’ll disassemble the engine before running it. I was also going to look at the head design to see if I couldn’t modify it to increase compression.

At the 1991 World Championship closing banquet, a sportsman handed me an engine and insisted I take it. All I had was few stickers to give him. We did the basic, I speak no Russian, he spoke no english routin and smiled at each other. I never re-connected the name or face. When I got home, I discover the engine had no connecting rod. I took it to work for a paper weight. I used it several times by taking it apart and having new grad engineers re-assemble it during thier job interview. It was a quick way to see thier mechanical nature.
Even I could tell it was not a valuable competion engine and so it sat.
Anyway, if anyone needs it for parts, let me know. You pay the postage and buy be a burger at Sloan’s next time you come to Lost Hills.

Randy, took your advise and disassembled the engine for a first hand inspection. It looked good inside and the bearings where good and tight in the housing! Re-assembled with appropriate oil in the right places. This engine seems to have great compression! 😀 I haven’t test run it because I’m not sure how hot of nitro I should use. Do you have any suggestions? I fly mainly 1/2A engines on 25-35% pop. I’ve heard and read that that may be a little hot for larger engines! What is your suggestion.

Not so. I run 50-60% as a matter of course .. your 1/2 A’s would love it, too06/11/2008 at 4:35 pm #45611AnonymousInactive
Whilst Jim is quite correct, I think it unlikely your Meteor is set up to use nitro in the 50%+ range. This engine is an old Super Tigre clone, and nitro in the 10% range is, I feel, much more likely to be what you need. To use very high nitro you would need to reduce compression somewhat, and possibly do some experiments with different glow plugs. Your description of ‘great compression’ sounds like an engine set up for low or no nitro.
