HDX 500 Frame and Main gear

[schucb]

I have the HDX 500 SE. It has the 94 tooth main gear. I am wondering if in the near future will it be possible to put the 130/140 gear into this model? Is there going to be a frame upgrade option?

I have burned through a few of the 94T gears.

I would likely buy a new frame and gear if it were available. I think there are many others out there that feel the same way, or am I wrong on that?

You too ???

We ( 3 of us in South Africa) are awaiting delivery of our gears , should be here tomorrow . We are converting the HDX500 SE V1 frames , been done before by someone somewhere on a different forum , with success , I believe

[schucb]

Do you have a link to the frame that would work with the original 500 SE?

[schucb]

When will this frame be available for purchase?

[helidirect]

Yes we are making new frame that can house 94, 130 and 140T.

You can buy side frames to update to house bigger main gear.

1. When will the new frame be available?

2. Where can I buy the side frames?

Brian, I can not give you a very good answer right now on "when" as we are at the mercy of the manufacture of the heli...I am expecting some items in very soon...but that is about all I can say...

as for where to buy...www.helidirect.com (http://www.helidirect.com)

We do have these frames in right now that will fit the 500 SE V2 along with the 500 SAH version...although I marked the description as only fitting the 94T gear..the opening of the gear slot is 77mm and the 130T main gear is 79mm...and they is plenty of frame material in that area that filing out 1.5mm on both sides of the gear slot will not affect the strength a great deal...doing this would allow you to run the 130T gear until the factory gets the new 140T capable frame out to us...

sorry I am not able to be any better help than this...

Thats interesting as I have the SAH frame set on my 500 from the kit and the cutout for the main gear is only65mm. Whats the go.

[Greg Alderman]

Falcon...these are the latest sets of frames sides that were supposed to be for the 500 SE v2...but again were cut wrong from the factory to fit the 130T main gear, so I put them on the website stating they ONLY fit the 94T gear. The SAH and the SE V2 share the same frame style...right now the SAH version comes with the frames made for only the 94T gear...they have a 65mm cut out. I believe sometime in the future that the SAH, SAS and SE will come standard with a cut out that will fit up to a 140T main gear.

Again...I am very sorry for all the delays and such...we are for sure the main distributor of the HDX line...but still are not the manufacture...and have only so much pull with them on timeliness of getting the product out and what the final product is like...It is very frustrating to receive a box of parts just to find out that the factory has changed the design of part and we had no clue about it...so I really do understand the frustration you guys are having...

Greg and others
This is a private experiment and we make no recommendations about it
As we are so far from the USA , we are "forced" to experiment a bit
We have received our 130T maingears and have - for now ) midified the standard HDX500 SE V1 frames to fit the gear. Carefull use of a dremel made it easy. The gear slot was widened by some 18mm and although it is quite close to the hole for the belt guide , I do not believe the integrity is reduced enough to worry about. The upper area of the frames i.e where the bearing blocks are mounted and where the main head forces "operates" are untouched except for the motor mount that was moved 9mm forward

We also changed the following to avoid head binding
- Fitted new V2 head
- Fitted Trex500 flybar control arms = this is 6mm wider than HDX so gets rid of flybar links binding on upper mixing arns
-Fitted SAH plastic cyclic arm /swash links as recommended by Greg
-Fitted new shorter upper mixing arms - the top ball links are suspiciously close to the seesaw cage - so will have to see what we can do there
-Also fitted Trex500 longer flybar and lighter paddles to increase cyclic response

Heli spools up nicely , no problems ,and we will now test the heli in FFF with stall turns, rolls , loops etc .
Will run standard 850 motor for now on 22T pinion and 2 Outrage 3S 2200mAH 25C cells in series (6S )
Then take it from there!
I will post a picture of the fitted main gear soon

Ok, here is the photo of the 130T main gear as fitted to the self modified HDX500 Se V1 frame

[Greg Alderman]

Hey all...I was asked though the Helidirect Helpdesk if I could post a picture of the cutout and the 130T maingear...so...here it is...the frame pictured is this frame set:

http://www.helidirect.com/product_info.php?cPath=38_234_252&products_id=4605

very little material is needed to be removed from gear cut out for the 130T gear to slide in...you should be able to take the entire amount off rear portion (left side of picture) of the cutout without any weakening of the frame...

I know this is not a perfect solution...the perfect solution is that HDX gets the frame machined correctly...but if you are in need of frames to install the 130T gear this little mod should work...

Hi guys further to my earlier postings

We tested the mods last night - indoors at the Velodrome
The HDX is transformed!

Unfortunately we only had 2 x 3S 2200 outrage packs so only about 3 1/2mins
- Cyclic response with Trex flybar and paddles and flybar cage is fantastic , handling like a 450 - we had to dial in some 20% expo
- No binding on swash with SAH plastic cyclic levers
- 130T main gear installation gave no problems - except do not put washers under the 6 screws that hold the anti-rotation hub onto the main gear - the gear is a bit thicker and the washers were binding on the belt drive gear above the main gear .
- Using bottom hole on mainshaft , giving more + and - pitch
Punch ups with standard 850Kv motor with 22T pinion was like an highpowered 450 !

Now for some 6S 3300 lipos and outdoors ! can't wait ........

[schucb]

I ended up selling mine. It sounded like the frame change has been in the works for a long time. I now too the money and bought a Trex 500. Several sites carry spare parts as well as my local hobby shops.

[falconea45]

If I was doing it all over again I would get the TREX500 but I like to have to do a bit with the heli so I don't mind too much. But I think that HD need to get things rolling a bit quicker and should discount on the frames seeing that the correct ones are not here yet and the latest still need modifying.

[RCnewbee07]

Here is the new frame for HDX500SE V2. It can fit up to 140T Main Gear. The frames are already modified to 87mm to fit 130T and 140T.

[falconea45]

Mine are already on the way.......

[Rototerrier]

Anyone know where to get the 140 gear?

[lotus7]

you can get it here !

I just bouth a hdx500se v2 with align 500L engine and 130t pinion..

but went the engine get hight revolutions i get a skuirt sound i think the pinion i not good config with the other parts.

and also the tail with the carbon fiber tail boom get some loosing it not tide well that make the tail kit, i think modifiying with other size of bolts ant tide it well it will fix up this issue.

the landing skids it's not so good, even the metall one get the trex 500 with entire skid pipes and everything, it work good.

the canopy dont fix good i have to do modifcations with 6 cell lipo,

For the align 500l and 130t pinion you have to do some mofication on bolt holes for fix it just drill and increase the gap

[falconea45]

kuryaky, read post #7 re the washers NOT to be used. This may be your problem with the noise at high rpm.
I use TREX500 landing gear

[Rototerrier]

I have to say, that is just about the ugliest bird I have seen lately. Hope the new HDX's fly better than they look. And with all the align stuff hanging off it...why not just stick with the trex? Seems odd, but to each his own :)

[kuryaky]

anyone can say me based on photos if i have to use all those gears, or i have to use just 2 the one that pull the tail belt and the main gear,

maybe i receive a extra pinion gear i dont know, for worse this bird become without manual, im little lost, the good thing is the bird already flight but with the extrage sound i does not seen to be damagind nothing.

also i have a question how much time i will give me this config

outrage 2200 25c
align 500l
align 100 esc
hitec 85mg
futaba 9657
130t main
12t rhino pinion

????
HOW MUCH TIME with the stick going up and down just hovering for test im a rookie
PLEASE SOME ADVICE...

[Wyldman]

Where, oh where can I get the proper build manual for the HDX 500SE V2? All I have been able to find is the V1 manual, which is different enough to cause some hair pulling issues that I can't seem to get past (& I really can't afford to lose any more hair!).

I can guarantee that I'll not ever buy another HDX product until they start including proper manuals or at least links to thier website where they can be downloaded. HeliDirect does a good job, but they don't seem able to stay current on the revisions, at least not on this particular bird.

Any help here would be appreciated...

[Greg Alderman]

Wyldman...I certainly do understand your frustrations...I really am trying to get HDX (Sonix) to complete a SE V2 manual...but they certainly don't seem to be in any rush...I wish we had a little more pull with the factory...as distributors we only have so much...

The closest I can offer you is the HDX500 SAH manual...it has the same frame style as the SE V2...he is the link to that manual:
