New Align Trex 600e Pro

My new Align Trex 600e Pro, kittens and banana for scale.

I bought this newly built, never flown heli on eBay at a steal with a new Spektrum Dx7S. The heli is bind and fly with all Align parts, a Castle 80A HV ESC, a Spektrum AR8000 with satellite, Align GP790. It came with two new Fusion 6S 4000 mAh 40C LiPO batteries (might be a tight fit, haven't checked) with EC5 connectors (convenient as that's what I use),, and a new 2S 2200 mAh LiPO receiver pack with Traxxas connectors. I need to vet it, take the head and the tail apart especially, check the gyro and program my Dx8. This version uses a flybar, which I wanted, and I will need to make sure its mechanically set up.

A couple of years ago i bought an Align Trex 600efl (flybarless), and have been byung parts for it. I finally have all the parts and along with vetting the new 600e I will be building the 600efl. That will take a lot of time.

 

Meanwhile I am cleaning up and servicing my other helis and expanding my heli shop (picks to follow)!

 

I am definitely back! Spending my motorcycle money, but I am back!

It's time...

I haven't flown anything since last fall... Fall 2012, back in Dayton. Kenny Chandler called me tonight on his way back from a fly-in in Jackson. He infected me. Again.

 

It's time.

Move Day

 

 

It really does help having professional movers. My last move could have gone much better. This time I went with pros, using Berger Transfer and Storage Allied Van Lines of Cincinnati. A crew of three experienced movers had everything packed and on the truck within 3 hours. The lead guy had a lot of experience packing RC aircraft and crafting boxes. The pic above is all my aircraft, except the massive Sopwith Camel, which got its own tailored box. I have no doubt they will arrive fine!

 

The T shaped box holds the Ultimate: I coudn't ge thte wings off without a lot of trouble. No problem, he made a box!

Moving II

Reminiscent of my last move... The planes and helis are off the wall, the wings off the planes that would let me. Hope they all make it.

New Flight Modes

Recently read a thread on Helifreak that discussed flight modes, and I decided to make some changes. RDLohr suggested setting Normal as a start up mode.

 

My previous Normal mode had a throttle curve that went zero to 50% then 75 and 100%. The Normal pitch curve was 40% to 50% (zero pitch) then 75% to 100%.

 

I had only one Flight mode. Throttle curve was 100%-90%-100%, and the Pitch curve was linear 0% (max neg) - 50% (zero pitch) - 100% (max pos).

 

Here are the new curves programmed on my Spektrum DX8:

 

 

 

Normal Mode "Start Up" Pitch Curve: A slight neg pitch, around -4 to zero pitch.

Allows the heli to come up to speed without any pitch.

 

 

 

Normal mode throttle curve. brings the heli up to 90% throttle at zero pitch.

Allows a nice transition to Flight mode, no sudden jump in headspeed when

switching into Flight mode,

 

 

 

Flight mode 1 limits the pitch to around -10 to +10 degrees.

 

 

 

Flight mode 1 Throttle curve. Some like a straight 100% curve. I have done that...The idea is that when there is no pitch the throttle is down 10% to keep the headspeed more constant, That's the thought anyway,

 

 

 

Flight mode 2 Pitch curve: Full -12 to +12 degrees.

 

 

 

Same throttle curve for both flight modes.

 

Practiced these curves on the Phoenix Flight Sim and it works well. I also like that it allows me to bring the headspeed up to full without any pitch. I did this primarily for the smoother transition from Normal to Flight modes.

HDX500se Up

The Blade 300 bearings I needed for the tail on the HDX came in today, and just as I expected, the new design is two closed ball bearings (the Blade 300 4x8x3) and a thrust bearing from a 450 main grip, on each side, just like a main grip. Went together fine, tight on with free rotation. I doubt this 4 mm shaft will ever bend.

 

I spun everything up without blades and things looked good. Put the tail blades on and still sweet, minimal vibration. Put the main blades on, and took her to 90%. Noticed that a servo twitched, the one I didn't replace before, the aileron servo. So I replaced it, and things look pretty good now. Perfect tracking.

 

I learned how to use the continuity mode on my multimeter and checked the continuity on my tail boom to motor mount static buster and the continuity is great (thanks psylence519 for the suggestion). For good measure I lubed the tube again.

 

So... now I just need some nice weather and a chance to fly!

HDX500: Yeah... its always something

On isolating vibrations troubleshooting the brown out and jittery servo problem, I found out the tail blade hub had a bent feathering shaft.

 

Parts for the HDX500se/Lepton are hard to come by. CNChelicopter carries many of the parts, so I went there and bought the last tail hub, and for good measure a couple of tail shafts (mine remains unbent).

 

Well, its not quite the same. The original (bottom smaller one) has a one stage 3mm shaft and is shorter. It uses 2-3x8x3 ball bearings on each side.

 

The new one is on top. It has a first stage that's 4mm for the ball bearings, then steps down to 3mm for thrust bearings. This arrangement is usually seen on the main rotor, I've not seen in on the tail, but the bigger the heli it makes sense. I will need 2-4x8x3 bearings on each side, and thrust bearings. I have the latter on hand, for a 450 main rotor crash stock. This will be assembled like a mini main rotor.

 

I checked with my usual bearing provider (Avid) and they are out, so I Googled and found another of my favorite sellers has them (WOWHobbies), for the Blade 300 I think. Correct bearing, comes 3 to a pack, of course, so I had to order two packs, about $6 a pop.

 

Now I wait. I expect this to go together just fine. At least that's what I tell myself. Still waiting for the HURC programming card and the back up Hobbywing ESC/BEC if that doesn't work.
