REFLECTOR: Armpit scoops..

[David Staten]

Our powerplant is the Mazda Rotary.. 13B (2 rotor).. should get about 
190 hp NA, have a PSRU, EFI controller and Engine Monitor from Tracy 
Crook in Florida (www.rotaryaviation.com) .. Engine was rebuilt by Chris 
and I last year, and I have been slowly collecting peripherals. I have a 
crude intake in place for initial start, and will likely buy a purpose 
built tuned intake from Mistral in europe.

Chris has some pics at www.lonestarvelocity.com    the second portion of 
the photographic builder's log has most of the recent stuff..

We have had two different rotary powered planes have first flight last 
weekend.. one in WA and one in FL.... so our numbers are growing..

A big thanks for the parts and the instructions..
Dave
