Hey brother, you can go back a few threads and I have some camera videos shot from a few years ago that are very short and a little shakey, but you get the idea. Yes I think .34's may be too much too. Like I said, my model weighs 5.5 pounds and it zips.

Hey I looked at the original plans I have and the CG is exactly 85mm or 3 and 5/8 inches. You would set up your CG machine to measure between the nacells and the fuselage for that spot with the model inverted...

Also very carefully check for hinge gaps. I had just a tad too much space in between the control surfaces and the maiden flight back in 2002 was a doozy. Almost full up elevator trim and full right aileron trim and it still had not leveled out. I did get her down and after I realized what was going on, I used 1/8 inch shrink tubing to seal off the hinge gaps by gluing one side only of the shrink tubing with RC 56 canopy glue and a toothpick in the gaps. It worked great. Next flight I had I needed full down trim and full left aileron trim to keep it flying straight. The third flight was great after I put everyting back to neutral like I had it to begin with.

Also you have to bring it in fast becasue the gound effect will make it drop on the runway if you come in too slow. No flaps on this one...

I have 7.5 ounce tanks made in china in my model. They are Octagonal in shape and fit in the tank area pretty snug, but they do slip right in there. I have to use ribbon and wrap the tank and secure it with scotch tape so I can pull them out when I have to.

I still used Sullivan rubber stoppers and tubing because the China made stoppers get hard in just one flying season and then the tanks start to leak air and fuel in them....

The Octogonal tanks came with the Mosquito model and I did not use them in that because they were too small. I get 6 miniutes and 30 seconds of flying time with the O.S. 25FX engines. I use 9x5 top flight power point props. They are carefully balanced and then I still have to go through several combinations of the props to get both engines running together. It is worth all of the fuss though.....

Mine is a little nose heavy maybe 82mm or so. She flies great. The really nice video I have of the model was shot just last month by a friend of mine. He shot the twin ACE and my CMP Mosquito the same day. It flew real nice too.... I will get it on here as soon as I can.

Go with the 25's if you can. With the 6 ounce tanks you will get about 5 minutes and they you will have about enough fuel to land the model.

Yes......use a timer....trust me on this one, this model is a flying brick and if one engine dies it's going in unless you throttle back fast and point the nose down and keep the speed up to land it quickly. It snaps really easy and if you don't hear one of the engines dying out, you will know it soon enough because it will roll over on a dime...

Good Luck

Hope the CG helps
