Tail Part Numbers

[Funky]

I recently purchased a Fury Extreme and I want to set it up nearly identical to my Stratus. I was curious about the different tails on my helis. They have 2 different tail pitch slider setups. I have looked on Heliproz, Ronlund.com and MinAirs Website and I cannot find these tail parts. I am betting David, Wayne, Knud or one of the other MinAir gurus can point out the part (and history/weaknesses/etc) in no time.... from memory :wink: I have seen this same tail setup on an ION-X, but I haven't seen it anywhere else. Is there any advantage or dis-advantage to one design over the other?

It also looks like my tail hub is a little beefier on the Stratus. Are there different hubs available? Is this anything like the PV0499 tail hub from the Raptors or the weak Trex hubs that need replaced?

While you are helping me out with these part numbers... does anybody know the part # and/or price for the new Stratus frame stiffeners.

Thanks for the info.

Above is the majority of the parts. There use to be a whole kit. I don't remember the exact part number.

The kit part numbers are:

3D 123-75
FAI 123-74

The frame stiffeners are 126-107

Ron has these in stock as well.

Thanks David and Bob. I knew you guys would know. I really appreciate the help :thumbup:

Is there an advantage to one tail slider design over the other? Any ideas on the different tail hubs?

[WayneBrown]

the only 'real' advantage is the FAI version has two contact points, where the 3D has one.
there are bearings in both pitch sliders, so no huge difference there.
I liked the FAI tail slider myself, seemed more rigid in hard stops...

[Caleb Phillips]

My friends and my Stratus's both have the tail setup your Fury had. I've never even seen the FAI version. I take it you bought your Stratus used and it came like this?

[Funky]

Thanks for the info Wayne.

Jonphilli, yes, both helis were bought used. The guy that sold me the Stratus said it was a "Tempest" tail upgrade. I have looked up the Tempest and the kits I have seen use the standard tail like my Fury. Both tail setups feel very smooth without slop. I was just curious about the difference between them. Thanks again to everyone for helping me identify the parts.

I can't wait to try out this Fury. MinAir makes some really nice helis :thumbup:

You can get an MA kit configured anyway you want it. The Stratus can be ordered with the fork type slider. Yes that slider originally came on the Tempest FAI model. But you can get that setup in a Fury Expert kit if that is what you want. MA just swaps the parts and then sends it to the dealer that the customer ordered thru.

Thanks for the info David. I've never bought an MA new myself but it'll be good info for future orders. :YeaBaby:

I am trying to get this Fury put together and I have a few more questions. Can you use the servo supports with 9252s? I have a set with only a handfull of flights that I was planning on using in this heli. The manual shows it with 9252s with the servo supports installed, but the brass shafts are threaded for metal gear servos? I mounted one on the tail servo, but the threads don't match up for the 9252s :dontknow Am I supposed to just force the supports in to re-thread the servos?? I know I can run it without the supports, but I wanted to use them if I could.

2nd question, am I supposed to have a spacer between the motor and the mount? It shows spacers in the manual with 8.18 gearing, but my heli doesn't have them. These are the spacers http://www.ronlund.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=heli&Product_Code=MA115-47 I ordered a set today. I just wasn't sure if there were any different versions of the motor mounts. I asked the guy that sold me the heli and he said he "thinks" it doesn't need them. I am not sure he understood the part I was referring to though. It looks like it lines up pretty good, but it also looks like it could use a little tweaking too :roll: The bolts are loose in the pic because I don't want to tighten it down if it needs to be spaced out from the mount.

Last question :oops: I read David's response in the other thread about the fan shroud. Mine has a hole cut for the carb. David, should I cut a strip up through to the head? This would also cut off the screw that helps hold the halves together. I am sure it has enough support with the other screws, I just want to make sure I understood correctly before I start cutting it.

.... ok... this is really the last question ;) Are you guys/gals running your servo wires inside the frame to the front or outside of the frame like the pic? I would like to mount them on the inside unless there are known problems with this.

Am I supposed to just force the supports in to re-thread the servos?? I know I can run it without the supports, but I wanted to use them if I could. Use the brass threaded inserts, just use a washer under the head so the hex part does not dig in too far into the servo wheel.

2nd question, am I supposed to have a spacer between the motor and the mount?
You need to check the gap between the fan hub and clutch driver, if the gap is even, you don't need the spacers.

Last question :oops: I read David's response in the other thread about the fan shroud. Mine has a hole cut for the carb. Don't do anything else, it's there as the carb body was hitting the shroud, if it clears, you're done.

.... ok... this is really the last question ;) Are you guys/gals running your servo wires inside the frame to the front or outside of the frame like the pic? I would like to mount them on the inside unless there are known problems with this.
You want to run them outside the frames. There are wire loops provided that fit over the head of the hex bolts to route the wires.
These frames are SHARP! protect your wires anywhere they contact the frames at an opening or edge or you risk cutting them. slit pieces of fuel tubing and CA them on the frames to avoid chafing where needed.

[DavidH]

Funky,
There is two different sets of brass threaded stubs. The ones for the JR servos have 3mm threads. The ones for the Futaba servos have 2.5-2.6 mm threads. The Futaba stubs will thread into plastic out put gears or Futaba metal gears.

The JR will thread into plastic or metal output gears on the JR servos.

If you have the 3mm threads, you can either get some Futaba stubs, or take a 3mm tap and run down into the plastic output shaft of the Futaba servo. That will work fine.

I run most of the wires inside the frames. I loop the wire between the frames from the servo so that the wire where it leaves the servo does not touch the frames. Then I gather the wires together with velcro where they exit the front of the frames and plug into the receiver.
The picture of your shroud. I cut out the fan shroud. The width you have now, I would take it all the way towards the head and take out the screw boss also.

Thanks for the info guys :thumbup:

What can I use to check the clutch gap? Any links to a tool for this?

I have both JR and Futaba servo supports. I guess I just need to be more agressive screwing them in to the 9252s. The servo screws in them now have very corse threads which is why I was concerned.

[WayneBrown]

just a feeler gauge, .030" if memory serves correctly.

[Caleb Phillips]

Before I forget, you should definately read Eric Larson's web page. He is a very knowledgeable person and has a great deal of info on his site. There's even a nice article solely dedicated to setting up the clutch gap.

http://www.ericlarsonrc.com/

Some of the stuff is a little outdated since he hasn't been as involved lately but like I said, it's sill definately worth the read.

Hmmm.... I was trying to bolt up a set of Vs today which are the typical 14/5 for MA/Avant/etc and I ran into a problem. My Fury uses 4mm blade bolts, not 5mm like my Stratus. Does MA make different sized grips? The blade grips look identical except for the bolt holes. The gap itself is the same too, just the bolt holes are smaller on the Fury? My manuals show the same part numbers for the Stratus and Fury grips (120-18) and same main blade bolts too (0082-1) :confused:

No more used helicopters for me.... this one has been a pain in the ass :arggg:

[DavidH]

4mm bolt grip

5mm bolt grip
http://www.miniatureaircraftusa.com/Store/proddetail.asp?prod=127%2D139

Take the 4mm bolt grip. Measure the outer diameter of a 5mm blade bolt. Then drill the hole in the grip to 5mm. This is what MA does. The reason I said to measure the 5mm bolt. a 5mm bolt is not exactly 5mm, it is a several thousands smaller. So if you drill the holes exactly 5mm the bolt will be sloppy in the hole.
I drilled my 4mm plastic grips and they are now 5mm. Forgot the exact size of the bit, but I did as I said above. I measured the diameter of the bolt and made the hole in the grips about .015 larger in diameter.

David you are the man :Bliss You always have my MA answers in no time!!!

After I posted, I measured the grips with my calipers and I couldn't find any other differences so my next question was going to be about drilling the grips.... looks like you are answering my questions before I can even ask :Slap Thanks for the tip about the bit size too.

I am sure this won't be the last question I have and I really appreciate all of the help with this heli and my last one too. Test flights for the Fury should be late next week if everything goes right.... crossing fingers :roll:

I don't think he's been stumped yet...a great source of knowlede, and.....no bs. :)
