Bill please remember to always post prop size used very important for us folks viewing the vid.

Knowing the prop size those of us with an audio tach can determine power out.

Average readings 14,698 to 14,780 rpm what is the prop size?

Sorry, forgot to mention the prop is an 8x4 Top Flite Power Point. I'm going to fly it today on my Jr. Ringmaster.

It flew well, for one short flight. I inadvertently set the needle just a tad too lean. It took off like gangbusters, got in about 5 good laps and a couple loops before it sagged and subsequently quit... blown glow head. The plane is too sensitive, I'm going to cut back on elevator throw and take off a bit of tail weight. The motor is going to be great. I have another Tee Dee .15 that I had on this plane for the test flight a month or so ago, but it needs more break in.

Well, last night I went to change glow heads between this TD and the new one I took off of the JR, and discovered they were both blown. Guess I'm ordering the Mecoa head and going to 10% fuel Huh...

Are Mecoa making glowplugs/heads for the .15 engine?

I can't see it on their website, other than coming soon...

Thanks for the link. It appears to be an adapter though rather than a glowhead. These are rather useless on the small engines but might be okey for the .15. Would be nice if you could possibly do a direkt comparison then?

I still have a few of the original ones from my hoarding days, but it is always good to know if there are working alternatives....
