Default *** Urgent, Whiplash CG request***

Greeting speed folks!

I have a gentleman that has PM'ed me asking for the proper CG on the Whip and I REALLY want to confirm it with other folks first. I recently change engines to a Novarossi-50 with full pipe so my CG may be slightly off from previous-

I show 10.5 inches back from the front of the engine rails at the center of the airframe. Can you folks kindly confirm any measurement you have? I just took my K&B-48 UT combo off to install the Nova and I do not want to mislead this gentleman.


Hell, I have had 3 that all flew just beautifully but I cannot find my manual or my Excel spreadsheet with the CG.

As you probably know, a CG request in the speed forum is URGENT since none of us trust the manufacturer and this guy might be ready to fly this weekend if he has the proper CG-

Also, I am totally wasted So I would appreciate confirmation of CG-

Cheers to all you speed freaks Electric and Glow! (Troy and mark F are my idols!)

Come on, you know the drill!
Move your fingers back and forth until the plane balances!
When the nose and the tail stay level your good![X(]
Being wasted will make it that much easier to locate!
If I really knew I would tell ya' but couldn't pass up the "your it syndrome response"!
love ya'

Remember Earl Scheib commercials on TV?

"I'll paint any car, any color, for only $29.95"

CG: Any plane, any color, it will fly at 25% MAC for the CG.

Except a Delta is usually 15% MAC for the CG.
