MA Koll Rotor Pro Balancer - Set

It’s very accurate on balancing blades. The “bubble “ could have been glued in but no big deal.

Classic tool for precision heli blade balancing

I've used several different balancers over the years but this thing is in a class all its own. Super smooth operation and incredibly accurate. Worth every penny if your serious about very smooth operation of your heli !

So this is the best balancer I’ve used worth the price imo thank you heli direct

Everything is fine, thank you.

Excellent p product and quality.

This tool is an absolute must for every heli pilot. In a few minutes you can easily check how badly off-balance your brand new blades are - and correct them!

The Koll balancer works very well. I tested it on a 600 scale Jet Ranger that was smooth but had a bit of a "buzz" in the fin. After checking the main blades and finding no issue, I found a slight variation on the tail blades which a small piece of tape resolved. I was skeptical that this little bit of tape would have any effect but the heli is dead smooth now. This balancer addresses cg as well as weight. Highly recommended.

Can't got wrong with this balancer. All my helicopters are as smooth as butter. I recommend this to anyone.

Great speedy delivery and great quality products
