Got it Larry, I have that hi cost blue aluminum balancing unit, EZ Balancer, Xmas gift. Had started to set up the Vanessa jig to the overhead beams in the shop. Seems to me the key to that unit is to get the rods used to raise or lower the nose of the model. .I would have installed knobs, star knobs for example, on to the rods that you twist to raise or lower the models' nose. Never heard anything bad about the unit with regards to balancing the model. My concern is that modelers make the mistake of not "Laterally" balancing the model. Thanks Larry. Chic

Chic,
thanks for the info. Maybe I can talk the wife into an ex balancer from Santa, I figure my chances are slim to no way 🙄🙄🙄🙄

The Vanessa rig is perfect for big heavy models (aside from getting scales, we they use for real planes). One example:

Expensive, but very accurate!

I was always concerned about pressure points on the wings when using one of those standard balancers. So I exclusively used the Vanessa rig approach for my bigger models (>20 lbs). There are some pictures of my F7F Tigercat being balanced in that old thread.

Keep up the great work, Chic!

Noah,

I've thought about getting the scales vs. using the Vanessa rig, is your experience been that the scales are better regardless of the price or does the Vanessa rig equal the scales for less money?

I have never used the scales... only witnessed them being used... and it was sort of a cluster! In the end they got it right, but it required too much thought, planning, math, and accurate calculations (and it also required about $200 for the damn scales).

The rig pictured in that F7F thread cost me about $4.00 (I didn't have to buy the set-punch that I used as a plumb bob)!

So, if I were facing these decisions, I would opt for the $4.00 rig and a plumb bob that points to the CG!

I bought the XCoy ballancer. It's not cheap but I felt that after 40+ years of flying RC it might be useful lol.
I like it.
I also constructed the Vanessa rig and I guess it works ok too?

OK Guys - I am allowed to discuss another of life's circumstances that has affected this family. I haven't worked on the Avenger for a couple of weeks due to another "Cancer" scare. Shirley has survived kidney cancer for the last several years. However, she had a continual source of pain in the area of her right knee. If kidney cancer metastases elsewhere in the body, it usually goes to the bones. That was the scare. After what seems like 20 or so blood, x-ray, scans, mri, and on and on tests, we were just told today that the spots seen on the numerous film results are not cancer. Relieved to say the least we are very happy and back to enjoying life again. Scared us both to say the least, but our prayers to God were answered "AGAIN". We shed a few tears, had a glass of wine, only one, and a great meal. I went out to the shop late this evening, dusted off the cob webs, and gave it ago for an hour or so between a few extra tears without her around. God is Good. Chic

Wow, Chic.... so happy to hear the good news. And so sorry to know you and Shirley have had this horrifyingly heavy weight pressing on you both for the past few weeks.

Thrilled to hear all is well.

Best

Noah
