Took six months to fabricate from scratch s-glass over a wood and plaster buck.
Yes - the box up front is the PSRU - cog belt driven.
Yes, most 2000 and up OEM ECUs are heavily tied into chassis sensors making them complicated or scary to use on other applications like aircraft where those sensors are simply not there to send signals back. You never know what the ECU response may be- from throwing a code to limp mode to fuel pump shutdown, ignition or fuel cuts. Hence the widespread use of aftermarket controllers where responses are predictable and known.

Kudos to get it all in there and running. That's a big job.

Tomcat RV 4 in Poughkeepsie, NY is finishing up - 4 with Subaru 2.5 stock eng., with airtrikes geared PSRU, SDS ignition/injection control. Nice thing about smooth auto engine, you can test fire without prop. Modifying RV4 cowl to cover Subaru. Fiberglass is not my thing, but can't be any worse than constructing old style slow build -4...Hope to have to airport spring/summer 2016...Someday photos.. If this works out as planned , would be inexpensive way into air....Have photos, but job, family life leave no time to get them onto VAF . Tom

Cool stability

With all the extra frontal area it might be a good idea to have a smart aero guy look at stability before you commit to flight.

Yep. Engine start with full down elevator...

My Rocket would be on it's nose in a heartbeat.

Will be interesting to watch the progress however. Always rooting for the alternative engine guys.

It sounds really smooth and quiet. Is it quiet in person? What kind of powerplant is it? Are there many flying? Hats off to you for taking the challenge.

2.2L Ecotec. I believe the late Bud Warren was working on a LSJ (supercharged Ecotec) a few years back. Not sure if it flew or not.

This design isn't my cup of tea either, but why all the snarky comments? What's wrong with experimentation and innovation in an "experimental aircraft" and on an experimental aircraft website? You guys sound like you wear helmets to bed. Sheesh!
