Status: offline 		I think I've finally decided on the right plane for this little engine - a '38 Mercury

The PB 0.33 should move it along quite nicely!
The airframe allows upright mounting with plenty of engine access. Built light - should float nicely.
Thinking 3 channel as the engine has the nicest little carb - I believe this is the smallest throttle carb currently produced.
I'm going to take my time with this build.



I purchased the Mercury model from John at FAI Model Supply
http://WWW.FAIMODELSUPPLY.com


And the beautiful little diesel engine from Peter Burford

Status: offline 		Bob,

Love those old time Mini-FF models. Adding a throttle equipped engine can only add to the enjoyment.

I keep looking at those SAM .020 models but they are only allowed to use Cox .020 engines and I can't get too thrilled about the class until they allow small diesels to compete. At one time there were some guys in Canada who were trying to legalize small diesels but never did hear if the rules for the class were changed.

I think your using a nostalgic .020 model with an RC diesel is a great idea and today's lightweight radio gear makes it all possible.

Wish I could afford one of Peter's little gems.

Stewart,

Don't like to be all pedantic on this crisp forum, but Peter's little engine is a .33cc, not an .033 cu.in. (0.5cc).

regards
David

Don't make Schoolmaster Owen get his switch out


Dan,
The little oldtimers seem like a lot of fun. I've had some micro electric experience and looking forward to this one. It would be great if SAM would make this concession - but I think it will be fun anyway. I may need that throttle just to keep the wings on - perhaps a bit of carbon roving at the diehedral joints.


Stewart,

I'm hoping to pass mine to my great grand kids - Peter had quite a chuckle when I ordered an extra cylinder/piston/rod assembly for this engine. Which brings up another point. Parts availability! I'm sick of trying to find parts for discontinued diesel engines. (Anyone got a rod/piston for a John .3? ) Peter can supply any part for his engine including all the "consumables". Or you can keep it in the curio

I know how it goes though - I've sortof parked a couple myself

Got a little work in on the wing, laminated some carbon roving on the leading and trailing edge diehedral joints.
Don't want to risk folding this wing - to precious a payload.
And a photo of the prettier side of the engine.

Status: offline 		I've only run up with the 6x4 but getting a solid 10k running conservative.
The 6x3 should give 11k and is the prop for this plane.
I havn't thought to tack the idle but the carb seems very effective - you can drop the revs a significant audible level.

Havn't run her up enough yet on the 6x4 to increase the revs on the 6x3.

Gear bent.
Motor hung - how many times on and off?

Leaving the carb off makes firewall bolts access easier.

You will have plenty of power for this 'plane, though you may need to try a 7 inch prop. with the frontal area.
On my web-site, I've recently posted photos of Bob's exquisite Waco UEC (FF) and some of his comments on flight.
Best of luck.
Peter

In the meantime I've gotta get busy on my eppanage.
