I ran this engine TT 120 before on an Ultra Stick 60. But only used the 15 x 8 prop.
The plane came in at 7.75 LBS including the lead in the rear.
Performance was just awesome.
It always started in seconds, the carb was like: set it and forget it.
I was just happy; my friends with their O.S. FX and O.S. LA were always having problems of one kind or another.
I also had a Thunder tiger 60 on my 60-size trainer. That one was not the PRO, $10 Cheaper and more powerful than the PRO counter part. It worked flawless too.

This plane with the 2 heavier servo's, 8.7 O.Z. battery, large tires, rear Sullivan landing gear, 32 o.z. tank, and Co-Pilot should come in just a little under 10LBS. I will see.

I hope people don't freak when I take it inside the post office, put on the wing, and place it nose down on the Scale.
You never know, one day I may want to ship it. I think I should know the weight and cost in advance. HEE HEE.
