What is this???

[Larry Fernandez]

Do any of you happen to know anything about this motor?
There is no name or size, stamped or cast into the case.

[bob whitney]

can we get a side viw of it  it could be one of about 3 engines

[Mike Greb]

Looks like a early nelson 40 pylon race setup for formula 40.    Possibly a 29, but unlikely with a pressure tank.

Hi Larry,

That is an example of the rarest of rare:  a 1959 Fixitwright Class D speed engine (displacement unknown).  Only one example exists and it was banned after its only test showed speeds in excess of 250 mph were attainable.  The exhaust trumpet was an integral part of tuning.  When connected to a specially shaped brass tuned pipe it would play Dixie when the optimum settings were reached, giving a new meaning to "tuned" pipe.

Post the pics in the speed section, maybe one of the speed burners know what it is. It's mounted on a speed pan.

   I think Mike is very close if not right on the button.

Looks like somebody put it in a rotory table and milled the fin diameter down to reduce frontal area. The quadrant "venturi" is pretty shocking to us stunt grunts, eh? Definitely a Nelson, tho. Can I have it?  Steve

[Mike Keville]

Nelson .40 with partially shaved head fins?  As Rich said, post the photos in the Speed section.  Someone there will spot it and figure it out.  (Paul Gibeault?  George Brown?  Bill Hughes?)

  either a nelson or a cyclon . cyclon made a nelson copy and had an anodized backplate like that one  looks like a full pan so would not be a 40  either 29 or 65   prob a 29 oops sorry F40 now uses a full pan also

By the way, Fixit Wright was a regular in the pages of flying models but few would have ever guessed anything of this caliber from him. (his sister was really cute though)

[Russell Shaffer]

It's a Flite Streak engine.  I want it too.

Many  do not use a Mill  to reconfigure the head like that... they just use the 80 grit asphalt or concrete... only take a few rubs  :-)

You know, Randy, early on I had a couple heads like that.  I found, through careful experimentation, that fairly well used concrete was the best abrasive to use.  The experimentation process cost a couple props, and some minor repair work to the airframes, but you can actually get some striking effects using this approach.  Knowing the exact entry angle helps to confirm the final result.

No doubt about it, the prior owner did not have access to a mill so it looks like he ground it down with 40 grit pavement.

I will be putting this motor on E-bay but I did not know what exactly what it was. Thanks to all of you for your help and insight.
