FINALLY!!!!! An Engine Day out in the Shop! Black Lynx Break-In and Pee Wee Backplate Run !!!

After several false recoveries, it appears that I AM actually doing better...health-wise...so-much-so that I cranked up the heat out in the shop for a break-in of Matt's "Black Lynx" .049 (THANK YOU ALL VERY MUCH AGAIN!!!)), along with my first test run of Bernie's .020 Pee Wee Backplate Assembly.

The Black Lynx was started up on Sig Champion 25% fuel, turning a 5-3 gray.  I ran it for over 1/2 hour nonstop with refuels on the run. leaning it out to peak and back as the time passed.  Toward the last 5 minutes, it was peaking in the mid 17k's, with good needle valve response.

While it may get some photo ops with the 2m B.O.T. before too long, it'll probably end up in my Cox Viper for this year's S.M.A.L.L. Fly-Ins.  Thanks again for this great engine!





THEN....I assembled an .020 with the new backplate I got from Bernie.  I chose one of my healthier .020's, hoping for as little hassle as possible, and am proud to say it all went well.

The upper mounting holes are REAL snug for my #2 socket head servo screws, and I wanted a washer of some sort to keep them from digging into the plastic.  So, I used a drill motor and Dremel to first, turn down the flange under the socket, and also rounded the flats of a couple #2 machine nuts.  

Drilled out, the machine nuts became thick washers, and fit into the backplate's top two grooves pretty nicely.  I know this all seems like a lot of fuss, and I'm totally prepared for someone to show me an embarrassingly easier way to do this.   The little sucker looks good to me now though!

It started up after little coaxing, fired up and ran steadily...also for a 1/2 hour +. I'd lost my light, and was too lazy to set up an led lamp for the tach, but sounding in it's zone.





Now, on to assemble another .020 and it's backplate for installation on my slowly moving Carl Goldberg Skylark project.
