I am pretty sure you have the BVM 1/7th F16.. Got to http://www.bvmjets.com/Pages/tips1.htm and scroll down. All the BVM kit CGs and throws are there..

Note That BVM CGs are usually quite conservative - nose heavy.

I believe that my old f16 is not 1/7 scale. It is only about 70 in long. But, thanks for looking into it.

The original BVM F-16 is nothing short of spectacular. I built mine back in 1994 and still fly her today on special occasions. Hard to believe she is more than 20 years old. My CG is 8.5" (12mm AFT from the drawings).

FUTABA T14MZ with R6014HS RX
BVM .91S Engine
Mix my own fuel but do follow BV and Henry Nelson procedures

Now that is superb!! I have a growing collection of BVM DF gear in the workshop waiting to be started. What fuel mix are you using?

Hey Jamie,

I take One US Gallon of Cool Power fully synthetic (by Morgan Fuels). The blend I use has 17% Fully Synthetic Oil and 10% Nitro (do Not use the MV Blend, which is also Green in color). Morgan Fuels also has some additional ingredients in this blend but lets leave it at that as the quality of their fuel is exceptional.

I then add 80 ml of Klotz BeNOL Castor Oil.

Total mix is now 3860 ml (3780 + 80)

The cocktail now consists of:

23% Oil (70% Synthetic and 30% Castor)
9% Nitro
68% Methanol (well close enough as mentioned before this does have some other small ingredients)

This Glow Fuel is used for my BVM, K&B, and Nelson Racing Engines.

Call me old school but there is nothing quite like the smell of unburnt castor oil on your shorts
