Hyper-Tiger fan hub
I've got a fan hub that uses brass insert cones to center it on the way to try, it just long enough on the bottom to elliminate the OS prop washer. I'll let you know how it works, this is the same setup that my Century Predator uses and I've never had one come loose on either of our P-Max 90's with a YS80 and YS91 installed.

JB at our Port Charlotte fun day that is what happened to Steven's Tiger when he tried to start it and we thought it was the starter cone, I just had the oportunity to pull it apart to see what the problem was and I put a new prop washer in and the thing spun again.

Yes, we've paid special attention to the fit of bearing to pinion gear, yes, that blurb in the manual is a touch of CYA.

The Pantera clutch hub uses a brass collet on the underside and a special tapered engine nut (replacing the one OS supplies) on the top side, such that the clutch hub runs between two cones, like on a Bergen Intrepid (thanks Chris for the solution). Also, Chris made me aware of what happened to them when they first used a pair of collets (one on bottom and another on top) and then used the engine nut - you couldn't disassemble it! In fact, you had to have a special puller to take it back apart. Anyway, Chris' idea was to use a specially machined tapered engine nut so we did as well. Actually this a trememdous advantage over a screw-on hub (like the EVO 50 and Raptor 50 use) precisely because you "can" dial indicate it.

With either the Raptor or EVO you just have to live with the runout you get because there's "no" adjustment whatsoever. Frankly, we were aiming for that same market (i.e. inexperienced, or without technical ability/knowledge to realize the advantages of the collet system) when we released the Tiger.

But the Pantera is aimed at a different crowd becaused savvy modelers have the flexibility of doing what the big boys do, i.e. the ability to precisely dial indicate that sucker to get it really, really smooth! Frankly, this costs quite a bit more to accomplish than a simple screw-on hub, but the advantages for the pros and highly experienced modelers were, in my opinion, worth the extra expense.

As for the clutch hub of this run of Tiger 50 models, they also use a brass collet (cone) on the bottom, just like the Pantera, to prevent the very issue Hootowl mentions, insufficient contact area and hence, they run nice and true as well. No, it's not the double cone system of the Pantera, but a Tiger 50 is nearly 100 bucks cheaper than a Pantera (and more than $140 cheaper than an EVO 50 or Raptor 50), and it's still superior to their screw on hub design that has no possible adjustment.

My 2¢

Since there are almost no posts about engine vibe issues with the EVO50 in the Hirobo forums, which is only second to the Thunder Tiger forum in number of posts, you can pretty much be confident the EVO design is a good one.

If the fan hub is machined accurately it will fit the engine shaft accurately. No dial indicating is required.

Are engine shafts off that bad that you need adjustable hubs? So far the Hirobo design has proven NO problems. So why complicate things?

He's turning his canopy into an oil bottle! LOL

I got a canopy that Bill did that to and it was a treat to paint. I'll let Bill explain the process.

The tunnel is used to treat plastic.
If you want paint, ink, stickers to stay on plastic you have to perform a surface treatment.
Two ways to prep plastic.
The first way is to lightly flame the plastic.
This is done with a lazy torch and just lick the flame to the surface of the plastic. Does not take much.
The other way to treat the plastic is to lectrotreat, or corona treat it. This is done with a tunnel, and several electrodes down the tunnel. Crank up the power supply to nice and scarry 5kv. Your making lightning now! Drive the Pantera canopy thru the lightning storm, and bam!
Your ready for paint, stickers, or ink.

The best way to test the treatment is to dip the part in water.
If the water beads up...it is not treated well enough, or not at all.
If the water "slicks" to the plastic and you have a nice sheet of water on the surface.
You have a good treatment.
pretty cool eh?

That's a very cool device, and a nicely phrased description of how it works. Adding the description of licking the canopy lightly with a flame (a plumber's torch works nicely) in order to make the decals stick better as well . . . well, that's exactly how we do it around here since we don't have a corona machine and it was well described. You're a lucky devil to have access to that fine piece of equipment!

Thanks JB,
You should of seen the line worker when a Pantera and tail fins popped out of the tunnel.
We have four lectrotreats, and 6 lines with flamers.
like you have said. The devil is the details!

I finally got to fly mine for the first time today. It flew really nice I put almost a gallon through it. After about 2 tanks I started getting her dialed in. I did some FFF,loops,rolls,a few autos, and inverted auto I didn't see how much fuel I had left and ran out on the top of a loop. All and all I really like it. The cyclic needs a little more tweaking a lot slower than my trex 600 also I switched the tail blades out for trex 600 plastic 95's now the tail is rock solid.

One tuning option you have is flybar length. Try picking up a longer flybar, I put the 520mm one from a Predator on mine and it was too fast on cyclics. There's a million choices out there, the longer it is, the faster your cyclics.

Ready to hit the sky
Got it done!
Snowing like a mo, and Flew the Tiger a bit today before the snow fell.
See how the pin jack comes out. Nice and clean. I can see the Rev Max and Regulator lights thru the windscreen.
Can't wait to start the break in on the hyper, and track the blade.
Time to shovel snow.

Lots of things you can do to tune the cyclics. There are four small black spacers included with the kit and two larger aluminum ones. These later two are used to space out the two close balls on the upper star of the swashplate. That will spice things up. Next, use one (or two) of the little black spacers under the ball on the Hiller arms (the black plastic control loop controlling the flybar). That will speed things up also. Also, you can give us a call for a 3D flybar - it's longer - and that will speed it up more still. Nice thing about the Pantera, there are more places to tune it than you can shake a stick at!

Hey Bill
Just to be safe if you haven't I would run a piece of velco or a strap around the battery and not rely solely on the rubber bands, you just spent alot of time putting it together.

Speaking of velcro. I bought some velcro tape at a local ace hardware. It's pretty slick stuff that you can cut to length. It has the "hooks" on one side and the "loops" on the other. Just cut to length and secure everything down with it.

Why bother? You're making a $280 heli a $500 heli? It makes no sense. People buy the Tiger because it's inexpensive and flies well out of the box. By putting all that metal on it, you are defeating the purpose of the heli. Sure put some meaningful stuff on it, like seesaw arms, and a swash, but there's no reason to put all that metal on that (or really most any) heli.
