Yup, prop sits still at idle unless you have a breeze and then it windmills. The two strokes apparently don’t need much of a flywheel because they idle really nice with no load. The clutch starts to engage around 2200 RPM. You’re supposed to avoid spending much time between that and 3000 RPM. I taxi at 3000.
I agree with everything Leni said about the clutch. I went to it because I’m running a fairly heavy IVO medium and there was no way to get a smooth idle without it. When the vibration got bad it upset the carb floats and ended up barfing gas out on the exhaust. Approach with a freewheeling prop and a slow airspeed gets you in nice and short but requires a shot of power to arrest the considerable sink rate and avoid an embarrasing “arrival”. The only other negative to the clutch is you can’t prop the engine, nor turn it over to bring a piston to TDC.
From the EAA website: ANTI-COLLISION LIGHTS Am I required to have anti-collision lights on my homebuilt? No, if you are only going to using your aircraft for day, VFR flight. FAR 91.205 lists the instrument and equipment requirements for standard category aircraft. This FAR does not apply to Experimental-Amateur Built aircraft. If you intend to use your aircraft for either night VFR or IFR flight, you will have to comply with the requirements of FAR 91.205 because the operating limitations you receive as a part of your airworthiness certificate will include the following language: “After completion of phase I flight testing, unless appropriately equipped for night and/or instrument flight in accordance with § 91.205, this aircraft is to be operated under VFR, day only.”
From FAR 91.205:
(c)Visual flight rules (night). For VFR flight at night, the following instruments and equipment are required: (1) Instruments and equipment specified in paragraph (b) of this section. (2) Approved position lights. (3) An approved aviation red or aviation white anticollision light system on all U.S.-registered civil aircraft. Anticollision light systems initially installed after August 11, 1971, on aircraft for which a type certificate was issued or applied for before August 11, 1971, must at least meet the anticollision light standards of part 23, 25, 27, or 29 of this chapter, as applicable, that were in effect on August 10, 1971, except that the color may be either aviation red or aviation white. In the event of failure of any light of the anticollision light system, operations with the aircraft may be continued to a stop where repairs or replacement can be made. (4) If the aircraft is operated for hire, one electric landing light. (5) An adequate source of electrical energy for all installed electrical and radio equipment. (6) One spare set of fuses, or three spare fuses of each kind required, that are accessible to the pilot in flight.
That grey head looks so nice and clean. How many hours are on it? I'm coming up on 300 hours this year and may follow your lead. I really appreciate the tear down pics. I noticed the EGT locations look to be possibly too close to the manifold flange. See: http://www.ultralightnews.ca/exhaustsystems/egt_probelocation.htm It would be a good time to measure them and remedy if you think it’s worthwhile.
No real secrets. You need to take off the cover after draining the gear oil to get to 4 of the 8 mounting bolts holding the gearbox to engine. Taking off the rubber donut is straight forward. Reinstalling it on the next engine reqires a compression clamp to line up the holes. Plan on purchasing a new cover gasket. I get mine from JBM Indusries. http://jbmindustries.com
For a shop installation, some use refrigerated air dryers. A cheapo is available from HF https://www.harborfreight.com/compressed-air-dryer-40211.html Still, $400 and only worth it if you do a lot of blasting and painting. Garage Journal has a number of compressor/ dryer threads with some decent homebrew solutions.
Those are Matco MC-1's. Out of production, but you can still buy rebuild kits. As long as the rubber boots are in good shape, they should be serviceable. Not sure if you can hook them up in tandem to have brakes on passenger side.
