When figuring center of balance for a cat (for example the skunk works gen 2) how do you measure it? From the ride pads, transom, or the end of the rudder extension. I know 30% is the starting point but where does this begin?

[tiqueman]

ride pade transom... not the transom overhang or the rudder extension. .. Where the stinger would mount if going twin.

Thanks Scott that is what I wanted to know. I have the twin stingers and rudder mounted and wanted to put the motors at the proper position and adjust with the batteries.

No sweat Genge. Havent looked.. you doing a built thread? If not... why?

[egneg]

I thought about it ... but folks have done quite a few already. I was thinking I would get it all put together and tested then post some pictures and information if folks wanted.

Couldn't help it ... sneak preview.

Looks very sweeeet. Hey, I know someone who could cut you some nice props for that!

I'd love to see a build thread for your skunk. I'd appreciate seeing it, actually. Ive got one that's about half built and would love to see other's ideas.

Another sneak preview ...

That looks sweet. Love the servo mount. Are the motor mounts directly on the bottom, or did you add some glass?

Thanks - I used modeling clay to dam up the area and epoxied the motor mounts directly to the bottom.

so do you measure it from the tip on the nose to the end of the last ride pad?
Any one have a picture how to measure it?

Great idea! Thanks

Yes COG is measured from the back of the ride pad (sponson) the measurement from there to the tip would be your overall. This particular hull, that distance is roughly 28.5". So if your cog is for example 8.5", from the back of the ride pad, your at 30% which is a good starting point.
