RE: Picco P-zero 0.8cc
It needs a drive washer with collet and a suitable prop nut/spinner. The shaft is short so it might be tough. Depends on how it's done. I'm going to make that and a new head and probably a venturi for testing.

It will be fun to convert one. Could one trim a few thou from the base of the cylinder and shim the head to tame it a bit for 30k-ish use?

RE: Picco P-zero 0.8cc
So, I have a CS .049 Speed engine apart on my desk(been there for a long time). The spinner collet and backplate fit the Picco. The spinner nose threads on to the crank, but the crank is too short for the existing spinner nose. A nut might be able to catch a prop. I might be able to run it without making a collet and drive washer. The liner-piston-rod assemblies even fit in each others crankcase, but they are slightly different. Bore and stroke are not the same. The crank journal diameter of the Picco is smaller than the CS. The crank passage is 4.7mm in the Picco, 5.7mm in the CS, and Norvel .061 is ~5.4. Maybe next week. I'll try running it, but it's supposed to be pretty cold.

That's good news about being able to adapt existing parts. If there's a will, there's a way!

If the crank is soft enough inside, you might be able to tap into it, then just use a screw like the TD does. Looks like a short run for inside threads though. This is not where a hollow crank is to the advantage.
Wish there was more of a nose on it. That carb extends way past the front of the case. Another tease of what would be a good engine to use past it's engineering for cars. I've been watching for something to convert to marine use with a machined water jacket head, and room for a dished back flywheel. They need to make it more generic or universal in that respect.
It looks like a good, high winding motor otherwise.

What size is that crank stud?

just machine a hub and nut assembly that has an ID threaded tube attached to the nut that goes thru the prop and inside of the hub. similar to the profi .15 combat motors.

I'd be inclined to stuff the piston, rod and liner into a Norvel. Where can you get those parts?

I'm wondering if this motor would be a good starting point for a 1/2A helicopter.... There is a company selling rip-off's (good ones) of the TRex for (gasp) $35!

Greg,
Please. ..gasp.. [sm=52_52.gif] .. I am going to soil myself in spectacular fashion if I don't soon see something posted that says "I ran it!!! Holy crap, whee!!" or even just "It runs, but what the f-?" or whatever...
Please... when are you going to run it?...

RE: Picco P-zero 0.8cc
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh......... 
thank you..
Seriously now, I am looking forward to hearing the news! Converting one of these little dentist drills for AC use has been on my mind off and on for a while. I had to take a break from eBay for a few weeks (pronounced "for-ev-er" in wife language) so I have stopped ogling them for the time being. The OPS .15 I scored just prior to my house arrest and subsequent sentencing can probably safely be treated with about the same casual disregard for over-revving - the conrod looks like it came straight out of a car engine.

Yeah, I told my wife I'd take a break from thebay during my house arrest too. I have many projects going though. This one is up there. The biggest problem is the carb location. It's very close to the front of the engine and I might only be able to run it with a venturi. It's supposed to break freezing Thursday, so I'm going to try for that.

do a search on ebay for sportwerks and you will find and engine the same size as the Picco Zero. In fact it looks a lot the same but it is not in the same class as the Picco. You will also find a seller who sells the Picco Zero for about $40 US. I have two of them waiting to be tinkered with but at the moment a down the list a bit. I am thinking perhaps maybe setting one up for 1/2a proto profile speed - should at least be in the same league as the commonly used CS 049's.
