As all you N9 fliers know, the crown gear is no longer available. I spoke to a fellow today that was able to modify the crown gear hub and use an MA0866-5 crown gear. He had to turn down the diameter of the hub so it would fit through the Miniature crown gear and he had to fiddle a little with the holes, but it worked and it worked well. He did have to shim it slightly. He’s going to send some pictures.

More to come.

Now if we can just find some booms.

Check  out the new instructions for the 3GX.

These pages are from the new 500 DFC Kit, RH50E02X which, oddly enough, does not include the 3GX.

I spent many hours removing all of the Chinese characters so it is easier to view.

The new instructions come in the new kits that have part numbers starting with RH.

The complete 500 DFC manual is available in 2 sizes:

Small: 10mb

Large: 125mb

The new JR XG11 radios are here. I checked the sticks and they’re a little better than the XG8. I don’t know why JR didn’t use the same gimbals they use in the 12X or even the 9503. They feel okay until you try to make a very small correction such as setting the pitch exactly at 50%. Then they stick a tiny bit. Other than that, it looks like a very nice radio.

KX018E15

This is the hottest T-rex kit on the market. No regulators. DFC Head. WOW!

Synergy E6/7 TT

Build it as a 600 or a 700. All the parts are there.

Thunder Tiger is in it to win it.

Facts that may help you find the parts you need

As I find things, I will post them here.

• The 550 V2 FBL comes with the H70020B spiral cut main gear and a
  Spiral cut pinion gear.
• The H50118 Paddles shown on Align’s site in the 550 category will not work on the 550. Use H60143 instead.
• The H60077A Metal Tail Pitch Assembly comes with the new t/r slide bushing, H60238. The length of the bushing is shorter than the old one and the diameter is bigger.
• If you are using the HN6102QF or similar elevator control, the control shaft number is HN6127. Some kits came with the old control shaft. The old shaft will work, but it won’t help you center the elevator bellcrank. A bushing is provided to get the right spacing. The slot on the old shaft isn’t centered. Ignore it.
• The H60221 Carbon Tail Rotor Control Rod that comes with the 600EFL Pro also works on the Nitro 600 V2 for sure and probably on all 600N models.

Recently, Align announced a new main gear hub for the earlier 600 electric and nitro models. They also released a new auto-rotation gear and a new auto sleeve. This new hub is a much better design and results in a significantly smoother auto-gear. However, the old auto-rotation gear isn’t compatible with the new hub, nor is the new auto-rotation gear compatible with the old hub. The old auto-rotation gear and the old hub have been discontinued, so…

If you need a new auto-rotation gear you will need to purchase a new hub.
If you need a new hub, you will need to purchase a new auto-rotation gear.

Another thing to be aware of is that the front tail drive gears for the older models are not compatible with the new “Pro” gears. The new “Pro” models, like the 600EFL Pro, use a different auto-rotation gear and front tail drive gear. It looks like you might be able to use the new gears in the older models, but you would need to buy both gears since the auto-rotation gear is a slightly smaller diameter and the front tail drive gear is a slightly larger diameter and both have a different gear pitch. Changing to the new gears will slow your tail down. The gear ratio of the new gears is 3.85:1. The old gears were 4.25:1. That knocks a thousand rpm off your t/r speed.

Finally.

Century is making gas conversions for both the Trex 600 and Trex 700 helicopters. The kits are very complete. Take a look at the 600 kit and the 700 kit.
