I built my venessa last night.
I was flying my tiger yesterday and added 1.5 oz of weight to the tail in 1/4 oz. increments.
I used the venessa to establish where that put my CG.
I then moved my battery back and was able to only use .5 oz of weight on the tail. I could move my engine back 1/4" on the engine mount if I feel I need more wieght in the tail to get it the way I want.


One change to the venessa will be to hang a small cheap laser pointer in place of the plumb bob I made.
This will shine a beem through my canopy onto the cockpit where I will mark the recomended CG as reference.


I taped a bubble to the wing. I realize now it doesnt have to be level as long as I didnt remove it between adjustments. I found the level to be more acurate than the blumb bob. The whole plane would osscilate back and forth very slightly and the plumb bob always was swinging. I think a laser pointer will work well here. althugh it to will swing..

Off to the field to try it out!!
