[QUOTE=bradleyban;2065905]Well don't get me wrong by the sounds of it, it's got lots of power, reliable, smooth, shiney but why make it weight so much?? [/QUOT

The engine does have extra plastic plates on the crank shaft that separates left cylinder air/gas charge from right cylinder air/gas charge and a huge carb to take advantage of the large increase in hp when pipes are added. This engine swings a prop with greater rpm than a DA 150L (info from kole) with pipes. I believe a 30x13 mej at 5950 rpm on tune pipes.

Great engine for planes that need a little weight up front anyway or for imac guys.

Yeah filling the crank case is a wicked idea. But that shouldn't make that much weight.

The carb is the same carb as the gp 176 and the crank is probably heavier than the gp 176. good or bad.

Re: The never ending engine thread, East-West

Kole and I have both asked for them to machine the crank case thinner and shave any extra weight possible. It won't happen for a while though.

Looks like there is only one way to test his findings. When the 116 shows up, I am sure Randy would like the bragging rights. I have the DA 150L and we can find a set of pipes somewhere. A EM video will be required. Not saying my DA150 is a power house but a test on the same day with the same conditions and props is the only way to separate myth from facts. What do you think?

Re: The never ending engine thread, East-West

I believe
Da 150L 7.26 lbs
MVVS 116 6.83 lbs
3W 110 cs 6.72 lbs
GP 123 5.15 lbs

similar power. Another way of looking at it I guess LOL

sounds like a cool idea.
bottom line, on pipes the mvvs out pulls the mighty gp engine according to kole. That is impressive.

He also tested the 30x12 mej and I think he turned 6200 but I have to go back and look at what he said so don't quote me yet.
