April 2000

Engine:

Baffles completed and seals installed. The extra heavy silicone type were used to obtain a tighter seal in most areas. Plumbing for the vacuum pump and engine breather was also installed.

Permatex Ultra Copper was used as a sealent in high temperature areas.

Cabin heat ducting was cut to fit and installed.

A gascolator blast tube was installed to reduce the possibilty of vapour lock to a minimum.

A Champion avaition-type spin on oil filter was used to allow for safety wiring. The fit appears perfect and there appears to be no reason not to substitute this for the automotive style PH16 filter recommended by Revmaster.

Cowl:

The stock Revmaster cowl required significant modification. On the lower portion two areas required bulging to clear the exhaust. The Bracket air filter was mounted in the center in a built up area consisting of three layers of 6oz cloth.

A small bulge was also required to clear the battery box. Starting to look like an ME109G.

An access door was installed to check the oil level.

Finally the camlocks (2700-7 or -8 in a few places) were installed per the Rand plans.

Avionics:

Transponder antenna cable routing and termination.

The VHF communications antenna was fabricated from a 1/4" dowel wrapped with copper tape. The ground plane consists of 4 pieces of tape 12" inches in length. The coax was soldered to the tape and then the assembly was floxed into position. The end of the coax and the solder joints were floxed to the antenna base (a 1" square of 5/8" thick spruce) for strain relief.

The antenna is slighty long (22.5"). When an SWR meter can be borrowed it can be cut down to optimum.
