And despite having the GP jig, I much prefer the Vanessa method. Less chance of the plane crashing down due to massive off-balance, or an ill placed jig. No worries if you're called away for the phone, or for dinner..
Also, the cat won't knock it over when she's jumps up & gives it the typical 'cat affection rub' !!
It'll take a bit of practice, but is well worth it.
I had one of the GP jigs too... until last year. I had a TF Contender that I just finished building balancing on it nice and pretty. Until... something decided to slip and down came the Contender. [:@]
I think the guy that did the Venessa thread comments about similar problems with the GP Jig. or doing the ol' two pencils (eraser side up) having the same problem.
I have had a 4*60 in the past and was very happy with it... and quite honestly that design will tolerate a fairly wide range in CG. Nose heavy will just make the thing sluggish on the elevator for the most part. And... better to be nose heavy than tail heavy. [&:] But with a good cg machine atleast you'll know exactly where you're at and adjust from there. (Good practice for future or more picky models [8D] )
