It's HERE!!! Remember back in 2011 when Ernie tried to do a successful YG4 (Yamaha Genesis 4-cylinder 4-strk 150HP) conversion and ran into so much trouble and headache he abandoned it and never did another one?
Remember when I did a YG4 right after it, and it was trouble-free right out of the shop and never quit, way back in 2012? Remember when I went on to be the first guy to sell YG4 kits in 2013?
Remember when Todd Rieck tried to do a YG2 (Yamaha Genesis 2-cylinder, 4-stroke, 80 HP) conversion? It never ran, they even tried to install a turbo to get it to spin the prop, and they abandoned any plans to convert THOSE motors.
Well, after I found out that Norman Lethbridge had built a successful YG2 gyrocopter, I figured what the hey, we're good to go!
My first YG2 customer is flying his Quicksilver floatplane in New Orleans as we write this, and I just took delivery of my second Phazer motor this week ($2200 form my vendor, delivered to my shop) and did some weighing as I unpacked it from the skid. Here's what we found, and IT IS SO EXCITING!!!!
Just 88.4 pounds engine, throttle bodies, hoses, some electrical stuff, remaining engine oil, starter, coils, plugs, thermostat etc.
THIS IS A VERY LIGHT 4-stroke, water-cooled, 80 HP ENGINE!!!
I added EVERYTHING else I could think of except the kitchen sink, and all-up installed FLYING WEIGHT COMPLETE this baby weighs just 123.1 POUNDS!!!
HOLY JEEZs are u kiddin me?? A Rotax 912 UL (is that supposed to stand for Ultra Light? if so, then LOL!) 80HP weighs a whopping 153.8 lbs, THIRTY POUNDS HEAVIER!!!
This engine is more on par, weight-wise, with a 582 Smotax, which is reportedly 117.2 lbs, at just 65 HP.
Here are my facts backed up with photos. I used self-zeroing electronic scales, accurate to within +/- 1 oz for the main engine weighing, and then a postal scale accurate to +/- 1/2 gram for the ancillaries I could fit on it.
Now, looking over the list you may notice I do not include the muffler with the rest of the exhaust. There's a very good reason for this.
FIRST: You MUST have the silencer/expansion chamber on a 2-cyclcle engine, and it MUST be included for a flying weights claim. HOWEVER we all know that a muffler is NOT required equipment on a 4-stroke engine, and is therefore NOT required to be listed for all-up, installed, FLYING weights.
SECOND: Mufflers for the YG2 which are thus a luxury, not a necessity, can weigh anything from a couple of pounds, up to the stock Yammie SS deal which weighs 18 lbs on the sled, friends. Your choice. I'll include whatever you feel you need.
Happy flyin, guys - hope ta see ya'll at Mentone soon!!!
Yours truly,
