Bush Caddy Teams Up with Italian Engine Manufacturer

By Ian Brown, Editor - Bits and Pieces, EAA 657159

After a five-year hiatus, Canadian kit manufacturer Bush Caddy was back at EAA AirVenture Oshkosh. Three years ago the company was purchased by an Australian named Tony Watkin, and he relocated the company from LaChute, Quebec, to CYCC, Cornwall, Ontario.

An innovative new engine is being offered for the Bush Caddy by an Italian company named MW Fly. It is water-cooled, comes in 115, 130, and 150 hp flavours, and has a dry weight of 185 pounds.

The unique feature of this engine is that it has a variable compression ratio. Normally 10.1:1, the compression can be reduced on the ground for taxiing and idle.

The engine comes with a health status annuciator (HSA-M) made by Milan, Italy-based PAT Avionics. The integration seems well thought out. With all of the innovations on show at EAA AirVenture Oshkosh, it would have been easy to miss the first head-up display for experimental aircraft, which was also produced by PAT Avionics.

HUD for experimental aircraft?

With a fuel-injected full authority digital engine control (FADEC), the engine can run on either mogas or 100LL. Prices are very competitive, and it will be interesting to see feedback from the first users of this innovative engine. In contrast with some other designs, this one seems to have been designed from scratch for aviation, rather than adapting an automotive engine.

For more information, contact Ackerman Consulting or Tony Watkin. The Bush Caddy kit family constitutes a choice of six aircraft designed as all-metal bush planes.

Watch for a first-flight report in a future issue of Bits and Pieces. There is a Bush Caddy very close to taking that first magical ride, and it's going to be based at my local airport.
