Went to 2 LHS to look for an Align part. Neither had it.
Took inventory of my spare parts for the 450. Had more basic crash stuff than I realized (10 maingears, 11 mainshafts, 9 spindles for example!). I had been ordering odds and ends to make up free shipping once and a while at Heli Direct and now I can figure out what else to get instead next time.

I learned a few days ago that my oneway bearings slipping was not the oneways failing but the sleeves wearing down. I don't know why I never looked at them when pulling the gears. I ordered 2 sleeves (should have gotten more!) and replaced 2 sleeves and 1 OWB on 2 helis. I'll get more sleeves on my next parts order.
I also did some swash leveling on one heli that was requiring me to pull up elevator while inverted. Kept me on my toes but not that smooth.

Weather has been bad so I've been working on the King. I had the HDX swash and washout base/arms in stock so I attempted to fit them with the top half of the Esky CNC head.

The HDX 450 head parts come in nice flat black and except for the included aluminum balls are a good value. The first problem I noticed was the radial arms on the washout levers were about 3mm longer than the Esky arms. This pushes the top half of the head up 3mm, or the bottom half (swash) down. I ended up not even using the HDX washout block because it's collar was too tall consuming even more of the precious shaft space. The HDX arms use the same sized screw as the Esky, so I fitted them to the old Esky block.

I had wanted to replace the Esky block because it was sloppy on the main shaft. On the newly installed main shaft, the block seemed sufficiently tight. That result speaking to the wear in the main shaft, now 400 flights in age, as well as my somewhat lax main shaft lubing schedule.

Since there is really no room to push the head up, I brought the swash down. This unfortunatly made the long links WAY too short. I'm using the Xtreme turnbuckles, and was not about to toss them in favor of a longer threaded shaft. In addtion this also meant that my swash to servo links were too long. Since they were already as short as the shaft would alow, that meant hunting down new even shorter shafts.

I was able to compensate for the hieght using the short links between the mixing arms and blade grips since I previously replaced the solid Esky link with an adjustable link. However that meant the mixing arms were not level with the blades at 0. I gave up and went back to the Esky washout arms.

Next was the swash. Everything seemed to be proceeding fine until I started taking some cyclic pitch measurements. I wasn't getting the pitch I was hoping for and tracked it back to two places. First, since the swash is wider than stock, the servos arms need to travel more. But with the Xtreme frame, the servo arms hit the frame at the top. Second, the servo arm mount points are slightly inboard from the swash links. So when the ball tilts upward, plastic ball end binds against the swash restricting the amount of cyclic travel.

During this process, I replaced the balls on the servo arms with the larger T450 sized. While doing so, one of the servo arms on a rear servo cracked requiring removal of the servo to access the screw holding the arm in place. With the servo out, you can clearly see the Xtreme idler assembly. That's when I noticed the boom was contacting the idlers. One of them was not spinning at all and it other was spinning with resistance. I guess the "stiffness" I had attributed to the newly greased main bearings was actually caused by this. I'm still running the stock belt and the 39t pulley. So the belt is stretched which is why the boom was jammed onto the block.

The other "bench save" occured while I was removing the smashed BEC. I had soldered it's power wires into the E3C connector along with the ESC power wires. I added some shrink tubing to help relieve the strain. It looks like the wires were bending right at the solder joint and one of BEC power wires was only strands away from coming undone.

I spent some more time with the HBK2 last night trying to get most amount of travel from the HDX swash before I give up on it. Try as I might, all I could get was 6 degrees of AILE pitch. With the Esky CNC head, I was getting 7. But I was able to get 10 degrees of ELEV and 11 degrees of collective. Up from 9 on the stock head.

6 is not enough so I went to put the Esky swash back on. I cleaned out the bearing in preparation for regreasing. Its then I noticed a grittiness in the swash bearing. The list of bad bearings is staggering. So far both main bearings, main grip bearings, one tail grip bearing, 2 idler bearings and now the swash bearings. No wonder I was struggling with a tail vibe. I'm surprised it wasn't worse. That should be one smooth running HBK2 when I'm done.

Over the past month I have been tuning up,
adding headspeed,
and servo throw,
and finally
weight reduction.


Ignore the hanging wires, those have been taken care of.

By removing the bottom plate and portions of the sides (and switching to CF tail) I have reduced the weight by over 30g (best estimate, weighing the removed pieces with a postal scale).

Still waiting on an ESC before I get to fly her.

Goblin! where have you been all my life?

Got my care package from ReadyHeli today. Ordered Thursday morning; arrived Saturday. Awesome. And they included my mints this time!

Got 2 Align tail booms, a set of Align 325 Pro Woodies, and red Trueblood V2 dampers (2 sets).

Installed the dampers and blades (MUCH better fit than the crappy BetterRC blades and even the B400 blades - the roots were too thick), checked tracking, twisted a link, and went out for a test fly.

This is more like it. Blades finally track like they should. The head response is a good bit quicker, which is good.

Good dampers, folks - they make a helluva difference.

Today I installed my new AR6100 and finished the new servo adjustment in the TREX450.

The old servo "jumped" at a certain point of rotation. Crash damage.

It flies much better now.

I also have a brushless motor on the way for the NOVUS FP (4#3)

BTW, this thing is great for practicing orientations indoors.

I'm hovering nose in with it. WAY tougher than the sim.

Finally got the HBK2 back together. This time I added on the front mount Xtreme battery tray which means I'm now fully commited to smaller packs. My remaining 3 Zippy 2200 packs will no longer fit but I'll hang onto them for another project.

I test flew with an old FMA 1300 pack and am getting 5 to 6 minutes. That pack is too long to fit the canopy over so I flew naked, Fender style. The new lighter setup was feeling pretty good, but the tail was a tad soft. A few clicks of gain fixed it right up, a little too well. On the fourth abrupt stop, the belt let go and the tail was a spining in free fall. A quick grab of throttle hold and some un-mowed grass made for an injury free landing.

I fitted a new belt on and had another go. The lighter setup is feels much better, more snappy and lively. That was what I was missing with the heavy packs. However there is a downside. The heavier packs gave the little bee the wind stability of a much larger bird. Without the anchor wieghing it down, HBK2 felt more like an angry knat, popping wildly about. Little gusts of turbulance would toss it this way and that. Up down, side to side. At least the new found responsiveness let me recover without breaking a sweat.

Now all I have to do is find some packs that will fit under the canopy.

I got in a mess of FG and CF blades for spares. Balanced them.
I also fixed a slipping front belt pully gear on an EXI450.
I"m also troubleshooting a Logitech 2100 setup in an EXI 450 that is acting funny. Then, I pulled out my original small electric CP, the Belt CP. It's missing an ESC and an RX. I went through my spare parts and picked out what I'm gonna put into it. I'm also going to use the original FM Rx I got with it and program it into my Futaba FM tx. Not sure what I'm going to do with it though once it's done. I have a scale Hughes 300 canopy I may end up putting on it, Not sure....

My flying bud Ken gave me his Old n' tattered Blade 400 Its been thru the mill and back but you know me, it was Free
One stipulation ofcourse, I had to remove to HS-65's and the futaba tail servo ----he wanted those back
So I rebuilt it from scratch and set it up---my way---- and was forced to use Esky 8 gram analogs for cyclic and tail

Took it out yesterday morning and it actually flew quite well, tracking right on, very stable, the tail would wag a little once and awhile but overall a nice flying machine. The cyclic was alot slower than I am use to so I did the "grip flip mod" and put on some VERY light paddles. We will see how it does today, might even "fart around " with shorter blades and higher headspeeds--- just because

This thing came in the mail Friday

Got most of the electronics soldered and set up yesterday.

The setup:
Neu 1910/1Y
CC Phoenix 80
NeuEnergy 6S 3900 pack
S9252's on cyclic
S9254 on tail
Logictech 2100T
AR7000
Turnigy MegaBEC 8 with 2S 1800 rx pack

So yeah, it's quite a step up from my flasher 450 with HXT900's

DTM, what IZ that?

I test flew the EXI 500 in the back yard after putting new spindle and mainshaft on it. 2 packs.

I troubleshot my LT2100 gyro. It was doing this extra rotation of 10-20 degrees after a piro.
Turned out it was because my tail servo was centered with a little bit of LEFt rotation instead of right. I flipped it into rate mode and it spun. Landed, slid servo up then tried it again and the problem was gone. Guess servo mount slid and I forgot to re-center that after the rebuild.

From what I've read it's an awesome machine. The head has virtually zero slop whatsoever. Here's some more pics:

I have been flying a 10T in the 500 and the motor was SWEET with a flat 100% throttle curve. But with just 10 teeth, it was not contacting the maingear well enough so it stripped the maingear today in some test flying in the backyard. So I put the 11T in.

Did some tail rework on the 450 flybarless also.

For once, all of my helicopters are in flyable condition even though 2 of them need test flights. I'm not sure this has ever been the case. I do think I need to inspect the OWB and sleeve in the TT e550 though. I believe I first flew it last November.

Hi, Im novice, actually has a Walkera 1#B electric tail wich is driving me crazy, burning motors. I woulkd like to get a Trex 450 Copter X or a Belt CP, I like the first since many people told me it’s a great stable machine, but also consider a Belt CP due I see it’s a very popular machine, Since I live in Argentina and these things arent very popular here, availabilty and price of parts they are a great point to have in mind. Well any input will be welcomed, thanks for them in advance. Alex

Walkera 1#B...that's really similar to an Esky Honey Bee CP2.

Can you fly the Walkera at all?

Which is to say, can you at least hover in any orientation for a full battery pack? If not, I recommend staying away from ALL the helis you mentioned. Get an Esky Honey Bee FP, any version. These are relatively cheap, quite durable, and when you DO crash, parts are pretty much available online to anywhere.

The helis you mentioned - TREX, CopterX, BeltCP - are all 450 size CCPM tail-belt-driven machines. Unless you can already competently fly a smaller heli, these may be quite a bit too much to jump into.

If you know someone who can help you set up and learn to control these larger helis, any of them may be OK to go with. But if you're on your own, start with something smaller and less dangerous and less expensive.

At least get a simulator to learn on. You don't need something elaborate and ridiculously expensive like RealFlight. Clearview (http://www.rcflightsim.com) is nearly as good and only $40. HeliSimRC (http://www.marksfiles.net/HeliSimRC/download.htm) is quite good, and free.

Check out the Honey Bee FP, Blade mSR, or Falcon 40.
