Greg,

The engine you have is an AME Zeus. It was designed for combat so you may find that it needs a smaller prop. You may have noticed that there are no provisions for a muffler. There is an insert for the venturi that will provide better suction.

The engine was designed for bladder pressure and small props (like 5x3). If you want to run suction and 6" props you have the wrong engine.

The engine I have is the engine I was given - it was not a matter of choice.

I happened to have a 6X3 prop in my prop box. I'll see what other props are available locally when I get out to the shops.

This whole thing is seeing what we can do with what we've got, not a case of shoulda got somfink else.

Having said that I have been told there is a pressure backplate available from Norvel, and I have yet to remake the head insert.

Thanks all for the replies & hints

Greg

If you don't have the venturi restrictor, you can make one easily that may not be permanent, but you'll have fun experimenting. You need to remove the spraybar, install the restrictor, snug fitting hardwood will work for a while, then reinstall the spraybar; be sure the hole or holes in the spraybar point in the same direction as the original. The restrictor needs a hole, maybe start with 1/16" on each side of the spraybar. Try enlarging the hole a little at a time. Of couse you could use aluminum or nylon, but the hardwood is quick.

Have fun, that's what this hobby is about!

Here's a couple of pics to show the insert:

I recently acquired this handsome (?) little bugger.

Of Indian manufacture, based on a well known English motor. Plain bearing 2.5cc.

An absolute delight, started easily on oldish Olly mix fuel. Tunes over a wide range.

Next question is what to put it in? Oh delightful problems.

Nice one Greg, how about an Ironmonger combat wing. Our old PB PAW .15 used to pull one around very nicely.

Here's my latest toy.

A Fora 09 mk1. The mk2 is available now so these go for peanuts on ebay.

They are a most unusual little engine since they are RIRE. The exhaust is split and the venturi feeds from between these.

They're also drum induction with a push/pull head. Did I mention how small and light they are for a TBR engine? Because of the small shaft, the bearings can be small as well. The whole front end just screws in.

This is the third of these in the MP club and they're intended for 1/2A combat hence the small stubby shaft thread to suit the 6" GF combat props. I don't have any so made a sleeve nut to suit an APC 7x4.

Sweet.

Ray,

That's a real cute motor. What revs on the APC 7X4?
