Hughes 500E 700 size Electric
This is the third Chaos 600 I have built. It is a T-Rex clone but the parts are about ½ of the T-Rex stuff and the kit is all metal head parts, fiberglass blades and frame.
I plan on installing a 5 blade main rotor, 4 blade tail, cockpit with pilots, and a 12s setup. I think this will be a fun project but I have never played with a 3 axis gyro before. Should be entertaining. Any suggestions would be more than welcome.
Plus it's preeeeeety lookin.
THis is the T-Rex 600 upgrade kit. You can get anything you want individually but I do love pretty. I will give more information as I install everything. Should be here no later than Monday.
I have a lot of experience with multiblades, in fact I make my owns, from three to five blades, and I mounted and fly others made in China with good results...so my thoughts:
First... BIGGER IS BETTER...the 700's size fuselage wil fly better than others, EVEN WITHOUT STABILIZERS
You do not need at all 3 axis Gyro or any electronics help, BUT...if you want to use just for sure I will recommend the cheaper Align 3G, I mounted an t-Rex 250 with multiblade head ( my own) and liked the stability, Rex 250 are twitchy to fly even with stock head, I mounted two Bell UH-1's flybarless, in all the same stability, even with hard winds.
I recommend the 3G because work well and better...is really easy to setup, the built-in tail gyro work perfectly for scales.
Now...I can pass to you some tips to improve the stability and control without the 3G ( or similar) and after finish the setup you can use the Flybarless with low gain.
In the video links below a few examples of my helis with and without Stabilizers...

One problem I've had with many of my Trex 600 scale birds is flex in the frames. On three of my Trex 600 scalers the top of the mechanics would have side movment. After going througn the bearings and bearing blocks I found that it was actualy the frames flexing slightly. I solve this by anchoring the top of the frames booth fore and aft of the main shaft to bulkheads on the fuse. On my century 500E I anchored the fuse to the top and then ran anchoring from the top of the mechanics to the base at an angle.

If you need help with your multiblade setup will be a pleasure to help. I like to experiment new ideas, and I will share them !.
At first i can say to you that: flying a multiblade machine is REAALLLY good, I just love to fly MD's with five blades, they are a lot stable, if you take a look in all the videos I have with MD's pay attention how easy they manteain altitude, and the smoothness of control.

We are getting close to flying her now. The inside of the aircraft is painted. Mechanics installed. We have 8 working lights including landing lights on a separate channel so they can be turned on during final.

The cockpit is in and you can see the adapter made by RC Aerodyne to install the 600 mechanics. I have good rotor height and didn’t modify anything on the install. Went pretty much as advertised according to the manual.

We have two 6S 5800 ma batteries and are still working on some wiring. The KDE stuff looks very nice inside and the extra strength is a welcome addition to the build. I don’t know what she weighs yet, will get to that tomorrow.

Here are some pics until we can get the rest of this build flight ready. We will have plenty of video and additional pictures after I get some needed sleep.

Yes, That is the new Scorpion 130A speed controller. We had to switch the mounting placement because of that monster but she is well worth the effort. They won’t be available for a couple of weeks and I will post flight logs from the first flights.

I really like the new feature of disconnecting the power lead before connecting the controller to you battery. You will notice a small red wire connected to each side of the power cable. This allows proper charging on the capacitors before you connect the main power cable and eliminates that huge welding spark you get when connecting large batteries. Also extends the life of the capacitors by at least 20 fold.

The lights are setup on the night fly 14 LED nav system and can be controlled from the radio.
I plan on flying the Chaos with the 5 blade head and the Skookum setup this weekend.

The weather is not cooperating but we got a small window to test fly the Hughes 500. My buddy filmed it with his I-phone. This obviously isn’t the video we are going to make but I thought you would like to see the maiden flight anyway. I kept her in my comfort zone for the first flight. Just a few little maneuvers to see how she handles. The Skookum is solid as a rock. We should get 10 minute flight times on this 12S setup.
