Using the factory setting technique/protractor and measuring at the tips it is currently set for 16.5 degrees. My CAM100 redlines at 6,000 rpm, but static tests at this prop setting produce 5,000 at full throttle. Prop reduction ratio is 2.4:1, so 6,000 rpm gives 2500 - 5,000 gives 2083. I originally flew with the prop set at 13 degrees. This gave me max 6,000 rpm in flight, but top speed was not high enough (105 or 110? as I recall). I then tried 18 degrees. Take off performance at sea level was not much affected - I got about 120 ias maxed out, but the engine seemed to 'labor' in cruise. Now finding that 16.5 is a good compromise. No wheel pants or other streamlining measures - cruise power set at 4800 - ias is 110 to 115 mph. The engine rpm doesn't vary as much as i'd expect with power increases... the theory of the warp drive tapered prop is that it aerodynamically flexes to give some amount of 'constant speed propellor' effect. I think this is so. For example, on a test climb to 10,400 asl, with engine at wide open throttle, the propellor rpm hardly varied ... 5,000 to 4800 range as the vsi fell off to a hundred fpm or so (and I was getting too cold! no heater) with asi at 80 mph for best rate of climb. I have seriously considered shortening my prop to 68" so I can get more rpm at wide open throttle while keeping 16.5 degrees - or maybe even going back to 18 degrees. But seeing as how this is an irreversible mod, I'll wait a while to be sure. The 70" prop at 16.5 at 5,000 rpm accelerates for takeoff like a jackrabbit! Very 'sporty' - almost STOL (but I don't have any good data on actual takeoff distance) and as you know from working at that high elevation airfield, there is always a tradeoff between takeoff perf. and cruise speed. Hope this helps, best Grant > I'm curious, in that I still am not terribly happy with what I have for cruise > speeds.

The Subaru, the Corvair, the 0-200, the 912 and the Jabaru 3300 are probably better suited to your needs because they deliver better power bands and propeller options. The least costly purchases are the Subaru and Corvair, and the least costly operation will be the Subaru, with the Corvair being a little faster. With the Geo or Suzuki, you'd be running wide open too much of the time, and you'd not see a long lived engine doing that.

Soobs and Corvairs allow you to save a ton of money, which can then go into avionics, HUD's, radar and three-axis autopilots and such. Being direct drive, you save near 2 grand, and some weight, and they are as reliable as a hammer. So what's your preference , water or air cooled? I opted for a Corvair which, being a six, is also smoother. Also, so many have done Soobs and Corvairs that there is a wealth of knowledge on what works and what doesn't.

I have a little lathe/mill from Harbor Freight. It looks like this: http://www.cooknwithgas.com/10_30_04_TorqueTube4.JPG I'll try to post some photos of the process, but basically I plan to chuck the drill bit in the lathe and clamp the chunk of aluminum in the vice on the sliding table. I'll start with the bit just sticking out of the chuck, then pull the drill bit out several times until the hole is the correct depth. This should keep it straight. The table slides accurately and there's a micrometer on the crank to let me know when to stop. I have a tilting table for my mill so I may get fancy and give the block a more aerodynamic shape. The gage is a Dwyer Series 5000 Minihelic II pressure gage, Model 2-5002. I've had it for almost two years ( I get ahead of myself a lot), so I'll have to do some digging to find the source. I remember it being than $30 but I could be wrong. I've seen them on Ebay also. On a side note I picked up a nut riveter kit for $12.99 at Harbor Freight last week. This is the best thing since sliced bread! It's model number 1210-1VGA and you can see it here: http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=1210 Have a good weekend, Scott Laughlin www.cooknwithgas.com N5SL (Reserved) 601XL/Corvair Working on Instrument Panel Paul Moore wrote: I'm not sure I can drill a 6" - 3/16 hole, much less make it straight enough to hit the other end with the intersecting hole! --------------------------------- ________________________________ Message 8 _____________________________________ Time: 09:34:49 AM PST US From: "Stephen R.

He's been able to extract the best from the 1.3 Suzuki and he went through a great deal of hands on engineering getting there. I'd still be hard pressed to use the engine with that redrive ratio, because it just puts too much rpm up front and the propeller size and pitch would counter to the best that could be obtained for the XL. The XL is capable of flying up to and beyond the limits of the LSA rules and I don't think you'd be able to stay anywhere near that with the Suzuki. He's proven it's a fine powerplant that can put a Nessa to work, but I'd not like to hear 6000 rpms any long period of time.

But the originator of this thread did not ask for comments on the engine only for a link to another site. I can think of none better then Jamie's. I had him as a guest speaker at our chapter meeting a couple of months ago and wow you should see some of the idea's he has going for the Subaru conversion. One thing I can say is that I will be building a 701 next I am leaning towards the Geo for that plane. Tom Mills has been flying behind a geo for 15 years most of that time as an Ultralight instructor in his 701 the hours have proven that it is a good combination in a 701 setup.

We also "grounded" the fuselage to the firewall with a bolted grounding strip (mesh type of flat wires) to prevent any arc though the bearings or other parts of the engine with the starting motor. paint might prevent the electricity to pass. By the way I have 2 ultralights with about 10 years os use, made with aluminum riveted with SS rivets, no problem so far, at least 2 trips to the coast per year. Here aluminum with SS rivets is a common use.

This person (Mr. Jim Alexandre) is a "hands on" person that makes his own parts. He does not sell parts, make plans or sell reductions, in fact when I got in touch with him, he just told me that all was in his web page. He does not do this for a living. But if you study his page closely there is LOTS of real info about this engine conversion. He in fact designed and built also his airplanes! they are kind of Kitfox - Avid look alike. No plans either. Enjoy and good luck. http://www.nessaaircraft.net/ I have no relation with him, just like his work and admire his reaserch and "do it yourself" way of working. My idea is (was) to convert a 1,800 VW water cooled in line engine, very popular and manufactured here in Mexico, but I think is about 120 - 150(?) hp. (dont know yet). So I intended to get advise from Mr. Alexandre, mainly about the size (wide) of the belt to use, given this more powerfull engine... Saludos Gary Gower.
