I had one a while ago . It need 4 lbs of lead up front , a friend made a mold and poured the lead into a horse shoe shape and it fit perfectly . but when i tried to land it a little breeze would come and it wanted to float by . I added about another 1/4 to 1/2 lb. and that settled the problem .

To meet 143mm CG, I had to add 6lbs of lead which I concealed in the nose chin. With the cowl removed no dead weight lead is visible, so one would think that no lead was required to meet CG.

I added the nose weight on the bottom of the fuselage in front of the firewall could not be seen with the cowl on , but maybe you needed more because you added the weight farther back .

I'm not complaining about the 6lbs of deadweight I added to meet what I chose as the CG, 143mm which is 10mm forward from what the manual states, I was just relaying where I placed and concealed the deadweight that resulted in a neat clean installation.



The 6lbs of lead is hidden in the nose chin.


The ramp under which the lead is hidden makes an efficient hot air outlet.


Air inlet outlet configuration.


Neat clean looking installation.
