Default Align UH-60 Blackhawk Trex 500

After some searching I finally found an Align UH-60 Blackhawk for Trex 500.
Since I don't have a Trex 500 I'll try to build one from parts and use clone parts if needed.

Here are some parts lists I have been using:

Found the metal bearing blocks and the 'bottom bracket' as original Align parts.

Still need to construct a tail from parts.

I wish you the best of luck putting the chassis together. It can be a bit of a slog trying to find all the parts. I don't know what the boom diameter is but maybe the latest 500 (in reality, a 480) might have a belt tail or torque tube tail to fit your needs. A second hand chassis would be the most cost effective solution but I don't see too many original 500's for sale. Try in a number of for sale sections in other forums and that may expand the parts base for you a bit. Take care.

You could use one of RC Aerodyneís clones as mechanics. Iíve used them before without any issues: https://www.scaleflying.com/500-Mech...D-_p_5170.html.

I do advise you to use the Roban angle gearbox though. The align gears are tiny, and strip out easily. The Roban unit has been reliable for me once I swapped out the bearings.

Got all the Align parts needed to finish the mechanics without needing any clone parts. Wound up getting the Align plastic tail grips, but better than none.
I did find the Align aluminum bearing blocks, however.

I went with the older Align 500MX motor which is 1600KV. It is a little lighter (per the facts sheet) than the 520MX which is on the current 500X. I went with that motor mostly because of weight and price. It cost about half a Scorpion.

Still need FBL, which will probably be Spirit.

Need ESC, which will probably be HobbyWing 80A v4

Servos will probably be Deko.

I have not decided on a receiver either. T-FHSS or FASSTest. I believe the Spirit/HobbyWing telemetry only will work with FASSTest.

Wow, the Align gears are small. Were you able to buy that Roban unit as a separate assembly? Where did you get it?

Here is the fuselage with the Trex 500 mechanics I'm building up from spare parts.

Today I got the metal bearing blocks and the bottom of the frame.

Waiting on the tail and boom components.

80A HobbyWing V4 came today as did a S-bus 2 Futaba Fasstest receiver.

My tests show I can't just connect them together and get it to send telemetry without a Futaba device called SBM-2 which I can't seem to find available anywhere.

So, for now, I'll have to hook up the telemetry by going through Spirit, then back to the Sbus-2 port of the receiver.

I got my Agusta A-109 running very well now, so the setup on this helicopter should be easy. I'll just copy all the settings from the ESC, transmitter and FBL. This will save many hours of toiling getting it to work.

Something Iíve done on my 3, 4 blade 500 helis is cut the swash driver from the head block to run vertical links. You would have to cut a vertical line on the head block for the pinch aspect and finish cutting through the driver. Many years of flight on two with no issues. the third is a new to me bo105 fuselage. It was given to me from a fellow helifreak member and it hasnít flown yet. I had to scrounge up enough parts to build another trex 500 for it but she is ready to fly outside of the blade balancing by the way of a scale paint job.

Servos are installed. Awaiting Spirit FBL.
I have put landing gear and tail boom supports on it to get ready for the test flights outside the fuselage.

This has had its maiden flight. I have lots of pictures of the build that I need to upload.

Main issues are:
1) A heavy battery (5000MAH) seems to balance best, but I don't have a good extra one now. The one I picked out for this heli turned out to have two bad cells.

2) There is an elevator wobble that showed up with the scorpion tail outside the fuselage. I thought that would go away when packaged in the fuselage. I was wrong. The up-down oscillations of the tail are still there.

So, I need to configure my radio for real-time manipulation of the "elevator filter" built into Spirit and see if that cures it.
Otherwise I don't know what is causing it as the mechanics and electronics of this are identical to the Augusta a109 which does not oscillate.
