SkyJeep Flywheel Replacement Viking Honda

Found two cracks in my aluminum flywheel.

The new parts require the reduction gearbox to move forward 1/4 inch. This causes the radiator to move forward, and interfere with the cowl.

I decided to try modifying the drive coupling by machining 1/8 inch off each side, thereby recovering the 1/4 inch.

I plan to do a few high power ground runs before flying, and will update this post with the results.…

CH701 flight test update

40 hour fly off is going slow. 9.5 hours so far. Having a couple of small issues....fuel is transferring from left to right in flight, not sure why.

Been adjusting prop pitch flatter, at 12 degrees, getting max 5200 rpm full throttle, level flight. Going to reset to 11 deg in search of 5600 rpm static. Makes me wonder about actual horsepower.

Engine itself is running smooth, no issues, but I do experience an unusual vibration when throttling back for descents (from memory seems…

First Flight N4707W

http://youtu.be/ApwXBLocMJ8

Aircraft passed airworthiness inspection. Had three small gripes, was able to fix on the spot. Fuel valve handle needed to be painted red, needed another "Experimental" sticker in the cockpit, and had to adjust cable retainer strap closer to the pulley at the aft baggage floor.

Aircraft flies great! Controls are responsive. Left wing is a touch heavy, Need a trim tab on the flaperon.

As…

Final Assembly begins

I am almost tempted to add stripes to the rudder. Almost...I'm tired of painting.

As it sits, it weighs 524 lbs. I am pleased.

Made a tentative appt with the DAR for the week of Thanksgiving.

Lightweight fuse/shunt cover

An A&P visited my project the other day and suggested a cover over the electrics since the installation is near the rudder pedal. This is a wet lay-up of 8 plys sandwiched in saran wrap, tucked around the fuses and shunt, and allowed to cure. It snaps right in.…

Latches for the rear corner of the doors. Made from 1/4" stainless hyd tubing. Silver soldered in a "bullet tip".

Compass error fixed

Compass and Dynon both dead on West.  Yeah!

Made this de-Gaussing coil by wrapping a bunch of magnet wire around a coffee can. I didn't make enough wraps to plug straight into the wall, coil got hot. Had to use the variac. This thing will magnetize or…
