Cool. Glad to hear it. Keep the reports coming.

So I got this thing flying last night after making some minor modifications and fabricating some things after reading about it here. I had no tail vibrations or any unpredictable flight characteristics from the main head. I did make that swash follower thing that was posted on HeliFreak a few months ago.
On my test flight, the only thing that needed adjustment was on the JR 410GT because of slight wag, but that was it. No trimming of cyclic! Talk about setup luck.
On the rotor head, the original mainshaft was used because the diameter is actually slightly larger and fit into the head with less play and therefore less wobble. I did have to grind some flats to keep the setscrews planted properly. I'm going to try the tail mod next with flipping the pitch slider to see if I can get some more tail authority doing pirouettes.

The HD 3800kv motor seems to not have enough power for this "heavier" heli. I'm using the 9 tooth pinion and think it will need a 10 because the headspeed seems so low.

Thanks to all of you that posted in this thread. I learned quite a bit before taking to the air with this thing.

My setup is:
Align 35G ESC
TP 1320 Lipo
HDX 3800Kv Motor
Futaba cyclic servos
Hitec HS 50 tail servo
JR 410GT gyro
Berg 7P receiver

Here are some pics of the heli after I flew it last night.

Hi Guys,

Why dont you ask about it at HD. The parts they sell may not all be that gr8 regarding the hdx300 and hdx450. But personally i must say that the customer support has been good for me so far.
(Sometimes the email is not being answered withing the first day or first mail, but they allways respond)
So did anyone exually tried this already?

Like a dutch old saying:....
If you never shoot, you allways miss.

(it exuaaly sounds better in dutch haha)

cheers,
Maurice

I did enquire at hd...even by phone...I was told ....all you need to do is dremel this... tap that...drill this... ream that. etc etc.


oh is that all? thanks hd. glad to have been your experiment for a season. Not.

[micen2]

Well.... I wish I would have read this thread before I bought the HDX 300. I ordered one Tuesday. Man, talk about a real let down. I have been so pumped about it and then I decided to read this thread. But I feel a little better knowing it is the V2 so maybe they fixed the problems. I hope so. We'll see.
You guys that already built one, do you think it needs more power. If so, I may buy a good motor. But I will fly it first to see if I want to spend more money on it.

thanks
Billy

Well the good news is, you can tell all the rest of us if they have atually tixed things. :)


Let us know.

yea....so if you're into buying new things and "fixing them" billy then you're gonna be jest fine :)

Supposedly the Version 2 is much better. If HeliDirect was smart, they would GIVE one to Finless to build and try out. ANd it is truely is fixed, that would be GREAT marketing.

it would be "great marketing" if they had researched thier product, before making large hype about it and selling it, in the first place.

Everybody makes mistakes, the true test is how you handle things when you do.

Everybody makes mistakes, the true test is how you handle things when you do.

I agree :wink: ....and that would be not "selling" upgraded parts for a "mistake" (or, better put , a lack of QC...but that's open to interpretation) . but rather providing them to former purchasers with proof of purchase.

Or...now here's a novel one.... :idea:

Not selling poorly planned/rehearsed helis (which require good mixing and mechanical properties by the very nature of it all), just to turn a marketable buck in the first place....


and ...what are they doing (with the new knowledge of thier "mistake") to replace my hundreds invested in a overhyped and slightly flyable heli. Maybe selling more upgrades again..?? for the upgrades??

[Pinecone]

I would go with reduced price replacements since most small businesses are run so close to the bone, they wuld just go away.

But no arguement that they should have tested and refined BEFORE selling.

It is not like they could find a few top notch "beta" testers to work out the bugs first.

[micen2]

buisnesses are not "all" run close to the bone....


that's the buisness ethic that keeps the bar low for quality....we gotta fight the power that be.

i say...if you arent willing to make a quality tested and tried product....you don't get my support.

anyone can run an add....anyone can sell an item....anyone can put company lettering on thier trucks..and handout company polos...and have huge buisness related writeoffs at tax time....but who can make a decent product...??


Those who put thier money where thier mouth is...that's who.

Hd does not feel sad or mistaken....they are just a "buisness".

At least the blade cp pro...flies smoothly, for it's wieght , size and price range.. with no mixing issues, or exploding (underbuilt) components.

The "blade cnc" does not.


So Hd rode the coat tails of a humble and entrylevel product...to "prey" on those who lacked "mileage"

How? By not researching thier product well...and selling it to a "beginners venue"....as something that will fly much better....at a costly expense.

It does not mix...fly well..and is poorly designed...and corners are cut on parts that really "matter". Dampening, rods, parts fit, shafts, head mixing design, etc.

[johnnychimpo]

I have 2 of the hdx300 head and was interested in the new upgrade but i dont want to buy 2 heads for the upgrade. HD should sell an upgrade package for exsisting v1 head owners. I contacted them about this and they responded with " We will not be offereing any upgrade packages for the v1 head"
The V1 has so much slop in it and it just gets worse in time and along with this problem i cant seem to locate a vibration and its driving me nuts!! :arggg:

[Casey A. Sigmon]

sup micen2 u get yours goin' yet?

[micen2]

sup micen2 u get yours goin' yet?

sup casey...




yea I had it flying fine...with the exception that the head cannot "blend/mix" properly...there's just too much slop in the head.......so I've quit.....next will be a large scale heli....probably a trex 600, or a nice "scale" heli from century , vario, etc (you should look at scale helis if you get a chance...very nice...retractable gear, lights, and all..(I like the bell 222, I think there's a good clip of one flying on google videos).......but ultimately I'd like to get a great sim first...and master 3d...before pouring thousands into a realistic bird.
Then will scale"" and slow flying...be easy to me...prolly already would be..(but you just don't crash those birds) since being able to recover from 25% slop issues in midair and a tail evaporating, in midair...sigh..that hd head really sucks....alot worse than a cp plastic head...a cp plastic head doesn't suck even remotely compared to that head.

I'm laying flying on the side for a stint, till I can really "put" into it, some fresh cash....and stop "toying" around.

All the new HDX 300 TX head works super.

No binding and it might be one of the best heads made closer to zero play.

Also the new tail shaft is great.

Happy flying

And for all, the HDX 40 FSE V3 might be the best heli out there, fly's better then any T-Resx i had over 100 flights and it is like on a train super stable and rolls straight.

Using HDX 450 3550 moter (stock) Otter 35A, futaba 401 (look alike only 40 bucks) HDX DS620 (same as Corona dual conversion receiver) and HDX digital servo's (same as Corona digital).

:D

[Pinecone]

Hmm, maybe Compy 300 with Trex tail and new HD mini Trex head would be a great little heli.

I had a corona dual conversion reciever and with any bit of vibration i lost total control of my hdx300. i do not trust that reciever in my heli's.

hmm :idea: .....*"wonders if you work for this manufacturer or seller."* hmmm

[johnnychimpo]

Interesting.... :lolol

[Pinecone]

If vibration causes glitching, I would suspect the crystal is loose or bad.

[Casey A. Sigmon]

Has anyone got theree hdx 300 flying , if so i need help again. Casey

[johnnychimpo]

yes

[wizard35]

Can anyone tell me if there is a video or instruction sheet for the assembly of the HDX300 Plastic Tail System (CNC Belt Conversion)?

[Casey A. Sigmon]

micen2 hey my hdx is still going nose left hard. I got the 3800kv outrunner with the 40 tooth pulley but still doing it. WHAT THE H@#! ??? Any suggestions? besides trashing it! although it would look cool falling 300 feet from my X-Cell. :lol:

[ptremb]

wizard35,
there is no assy.instructions/vids for the plastic tail,what part don't you understand so I can help out.


Casey,
Have you verified that the tail drive sprocket is not spinning on the shaft?
Did you file/grind some grooves in the mainshaft for the set screws to "bite in"
Are you getting full deflection on your tail rotors?which tail box do you have?
What is your max pitch set at?
What are your pitch & throttle curves set at?
