Still awaiting my Belt CPX & accesories arrival but was wondering if I should be ordering a swash plate tool and pitch gauge as well?
Can anyone one recommend the correct swash plate tool (8mm shaft?) and pitch gauge (Turnigy?) from HobbyKing?
(XHeli seems to be sold out of both) Confused

I don't know your location but you might look at Horizon Hobby for both of these tools. And yes you will need them.

Thanks Jack,
I'm in Canada (West Coast, BC).
They're pretty pricey at Horizon compared to Hobby King and XHeli but will keep them in mind. As far as I can tell (still waiting for my delivery) the CPX has a 5mm main rotor shaft.

So I'll arrange for a pitch gauge and swashplate leveler. I'm wondering about the blade balancer. Is this just a fancy weight machine that tells you if your blades are different weights or does it allow you to actually do something about it? I can't imagine how a new set of blades can be out of balance, but, hey, I'm a bit of a noobie...so.

Thanks again jack. Rolling Eyes

Trust me. A new set of blades are ALWAYS out of balance. You can make a balancer. But for 5 bucks why bother.

The best thing about Horizon hobby is that they are always there with Product support. The are second to none. And they are real good at keeping things in stock. Guess that's because they are a blade distributor and that's what I like to fly. Blade stuff. Horizon Hobby has been there for me many times. They have never like me down. Most the time the other folks you can't get on the phone. Plus they are slow to answer emails.

Just my thoughts. Everybody has an opinion.

PS: Update you location in your profile for us. Thanks

I like to use the Tombo242 method for blade balancing and i never fit any to the heli without checking. Out of balance blades are bad news for an r/c helicopter. Here is an earlier thread showing members various favourite methods. http://www.electric-rc-helicopter.com/phpbb/simple-blance-rig-t4117.html

Certainly works for me Chopper, been using the same nuts, washers, bolts and glasses for years now.

That makes perfect sense. So, if one blade is heavier, what do you use to balance\weight them even?

I just use that silver coloured duct tape from a diy shop. Small pieces wrapped over the leading edge until the rotors balance on the tumblers.

I use ordinary clear sealing tape, always from the trailing edge over the leading edge and back. I like Choppers idea though, silver is good.

The swashplate guide sits bolted behind or in front of the swashplate and stops the bottom half from rotating. It is a part of the helis swash control.
Here's a vid of mine looking through one on my B400 in flight.

Link



The swashplate levelling tool helps level the swash with the head removed allowing the servo links to be ajusted to level the swash.

There are 3 types:
1. Over swash fitting to mainshaft. This is the usual one used. Heli level need not be horizontal.
2. Over swash loose on mainshaft with level bubbles showing level or lack of. Has to be on a true horizontal surface.
3. Under swash. Used to set the swash at its' midpoint with the servos centered.
Sample of #3 with US dimensions:

In use:


Hope this helps,

Tom.
