I'm looking for a suitable engine for a 1/2A type project.

Guys - I need help. Who can tell me what's available in the small end of glow motors.
I want something with a throttle that's a touch more versatile than a Cox .049 and smaller than an ASP .12 - What's out there these days?

Norvel is coming back in from the void.  The mother company that they were a part of got too busy with (IIRC) Government projects which is why their great engines disappeared.  There is more info HERE.

Brodak has an RC 049 -- http://www.brodak.com/shop.php?CategoryID=62.  Note that I have absolutely no clue how they work -- I've never seen a Brodak engine, much less an RC one.

I just know they're out there...

And the Thunder Tiger GP-07 is still widely available. The couple I've seen have been pretty good little engines.

After a lot of umming and arring  - I went with the NV Big Mig 061 R/C.

The big attractor for me was weight 57 grams/2.01 oz and power not far off the Thunder Tiger 07 plus - integral piston and liner - variable compression [with shims] - propeller bolt [like Cox].

The Thunder Tiger 07 was a contender but at 94 grams 3.3oz this is getting a bit big and more like what I used to fly with.

Brodak gets a mention but they don't do carburettored small engines.

Now, who can recommend a tuned pipe maker for a 1/2A engine?

My biggest regret is selling my Novel .061 R/C engine. Hindsight is always 20/20.

Yup, sometimes hindsight is 20-20. Tongue

Thread's a little old, but in keeping with the sprit, if one doesn't mind old school and noise is not a problem, a non-muffled 1966 model OS Max .10R/C cross scavenged engine only weighs 3.1 oz and makes a nice upgrade to a .049 plane. It is one of the smoothest throttling engines.

Noise at full throttle is same as a .049 reed valve. With exhaust baffle plate for reliable idle linked to carb, at half throttle sounds muffled, at idle it is reasonably quiet. Enya .09-III same vintage is also good, a touch more powerful, but weighs a full ounce more. Anyway, YMMV (your mileage may vary).  Grin
