Default Which Jett Engine?

I miss flying the Pattern Planes of the 70's....they flew great! So I'm thinking of building a Joe Bridi Dirty Birdy or the Bridi XLT with a rear exhaust piped engine. On the XLT, the pipe runs back through the canopy like Wolfgang Matt's Super Arrow. I want an engine that will make the XLT scream through the sky....I mean something just below Mach 1. But...at the same time, I want an engine with good handling characteristics...easy starting and good reliable idle. My question is: "Which Jett engine and pipe would be best for this airplane?

XLT Specifications
Wing Span: 65 inches
Wing Area: 845 sq inches
Engine Size: 10cc - .60 (2 Stroke)
.90 - 1.20 (4 Stroke)
Est. Weight: 7.5 - 8.5 lbs

The Bridiâ„¢ XLT is designed for tuned pipe and retract landing gears. Foam wing and stab with 3/32 balsa sheet covering. Capable of the A.M.A or turn-around pattern. Comes with a fiberglass canopy for rear or side exhaust engine.

I am also considering the new version of Don Lowe's Phoenix 7.

Regards
JC

Default RE: Which Jett Engine?

sorry for the delay, and thanks for writing...

I build and flew the XLT and Escape years ago. Great airplanes.

Simple answer on the engine - FIRE BSE-90, Mac quiet pipe. Have Dub set it up for an 11x9 prop.

Very user friendly engine. No bad habits. Verfiy the header rise size when ordering the engine/header/pipe.

If you search in the Classic Pattern forum you will find a couple of XLT and Escape projects with this setup.


On the PHX 7, a different choice there.
That was designed before the "big block" .61 engines. Or rather in the transition when the Webra Speed and OS 60FSR were first hitting the scene.

The Hangar 9 P-7 is designed for the "Small block" .60 engines.
The jett engine you would want is either a Jett SJ-56LX with a full size pipe, or a SJ-60 with the jett-stream muffler. Prop selection depends on the engine and how you want to fly. But figure on a 10.5x7 (if you can find one), or 11x5. You want the engines to turn up.

The OS 55AX with a jett-stream -11x6 prop is very good too, and I also recommend the Evo 60 setup.
