V Balancer with Lead Set?
 

Hi,

So it's been a funny many few years for my family.
My dad wanted a good RC helicopter since all the battery operated ones we had gotten him were terrible, even when we'd gone slightly pricier (or so we thought).
So my mother and my brother and myself decided to go in on a gas powered one for him.
At the time I shopped around looking for one that claimed to be friendly for beginners but also have some room to grow in skill before you'd think to upgrade.
I settled on a Heli-Max Kinetic .50 ARF Nitro Heli. It met the claims of being both beginner friendly, but also with the ability to learn some more advanced techniques.
What I didn't realize was that it was just a frame. We were so used to the pre-builts we'd been buying him that I figured $400 sounded fair for a beginner friendly gas powered heli.
Anyway, that was many years ago, and since then I have been alone in buying him the parts to complete the machine. For whatever reason my mother and brother immediately gave up, so it's been slow going getting him the parts.
He finds it amusing to wait and watch each piece appear at Christmas or his birthday.

I'm nearly done buying all the parts for him, but looking back at the build I had compiled I had written down that I needed a V Balancer with Complete Lead Set.
However the one I had chosen got discontinued and no product page was left for me to know specifically what it was.
I tried asking a couple online shops but they couldn't understand what I was asking after, or simply didn't reply.
So can someone help me by explaining what part I am looking to get?
Google has not been kind to me on this one.

And don't worry, he has a teacher for his heli once it's done. His brother has been in the hobby for years and will show him how to fly it once it's ready.

Thank you!
