Re: IAC competition in YAK-55

I did compete twice last year in Intermediate. It's now Christmas 2019 and the proposed Known for the US IAC competition season has been released. The Intermediate is easier than last year (I don't care for it) and the Advanced has more 'Push' than I care for (at this time) The Yak is running fine. ...

Re: Paging shipchief

Hi Jay; I haven't checked this site for a while. The first year I had my Yak-55M at Acro Camp, the instructors were very taken with the plane, but one of them warned me to stay away from the MT 3 blade, it would be a disappointment. So I elected to go with the Whirl Wind W-530 blades as I documented...

Re: M9F Magneto

Here is a pic of the coil firing through a piece of 8mm MSD brand spark plug wire that replaced the original. The spark easily jumps the 10 mm air gap when the drive end is turned by hand. The long piece of wire from the coil (in a previous pic) attached to the points, which were dirty. Once cleaned...

Re: M9F Magneto

You can see the damaged insulating sleeve on the extension piece in the previous pic
This is how it goes together. The tab at the base of the coil is the contact for the P lead. Grounding this terminal shuts off the magneto.

M9F Magneto

Last week I experienced a magneto failure during run-up...for departure to the Corvalis Corkcrew IAC contest. :cry: I flew Sportsman (poorly) in my RV-8. This weekend I worked on the Yak. Of course, I started by accidentally selecting the wrong mag to disassemble. I figured it must have been the one...

Re: IAC competition in YAK-55

Thank you Neville. This week end I attended Akro amp @ Ephrata WA, I think it was put on by the Canadian IAC closest chapter. There were 4 unlimited World Competitors on the ground, giving radio instruction in rotation. Each attendee received three 15 minute lessons per day over 3 days. I still don'...

Re: Whirlwind Propeller blades

Yesterday I spent most of the day with the Yak & Dyna Vibe. I eventually ended up frustrated. The frame I made to hold the synchronizing light and the vibration transducer may be vibrating from propeller beat airflow or something... I tried several combinations of weights and locations, and chained ...

Re: Whirlwind Propeller blades

Today I put the DynaVibe prop balancer on the Yak, the first time with the new blades. I flew the Yak yesterday, and the vibrations were pretty bad, similar to the original paddle prop, feeling like a washing machine on spin cycle with all my blue jeans on one side.. Although the tip vortex vibratio...
