Thanks. If the Yak55 is known as "The Laser Yak" then I think it should have wheel pants like a Laser!
Plus, I want to know if these pants will increase top speed by 10 mph like they do on a Thorp or an RV? Yak55 is not particularly fast, so +10 would be most welcome for cross country flight to a contest.
Being black Carbon Fiber on a black plane is all the better!
The pants do make it look mean! Paint job is also nice. I follow a couple of guys on Instagram who post Yak pics and videos, definately gets my attention.

Acro Camp is just around the corner.
I completed the condition inspection and cleaned the the engine compartment. While doing the compression check, I noticed the automotive spark plug conversion; the inserts in the head are threaded deeper than the NGK BR6HS spark plug reach of 1/2". My compression tester thread in adapter has a deeper reach and the threads were goo-ing up on the combustion deposits of the un-used threads in the upper cylinders. I'm wondering if there is a better spark plug that will thread fully into the head insert and possibly have an extended tip for better firing of the fuel charge etc..Meanwhile, sticking with the accepted plug.

I attended IAC67 Acro Camp at KEPH June 8,9,10.
I arrived with 11.5 hrs in the Yak55, and flew only once per day. Three 15 minute sessions with critique & instruction are offered per day, but I was not "G'd up" enough to take advantage of them all.
I started with rolls and looping maneuvers, pulling 4 G's and a couple of spins. The second day really improved my 'rolls from inverted' and point rolls. The last day I was flying a score-able Sportsman Known routine, pulling over 5 G's. The Critique / teaching team told me that I fly well for so few hours, that I need to back off on the G's and work up my tolerance.
I say Yak55 makes a pilot look good.
I bought a digital Carbon Monoxide detector and use it while operating the Yak. I smell exhaust, and do get readings above the preset alarm point of 35 ppm at start up and run-up. In cruise and holding for the aerobatic box readings of 6-10 ppm are common.
I've purchased new style exhaust clamps, shims and gasket material from M14P in Arizona, the old clamps are rusting out and the gasket/shim packs are worn, although I couldn't find any glaring leaks.
I'm seeking a complete M14P tool kit...required for checking tightness of intake & exhaust tube seals, setting mag timing and all those other frequently required maintenance tasks.
