I know what my next heli is

[tom dubya]

ok slightly back off topic. Ya are old forum is just not as fun as it use to be. The things people post sometimes or can't post makes me scratch my head in confusion. I posted links to here wondering if they'd get censored.

But to post maybe on topic. im slowly but surely shifting my next heli into a hdx. I have the head on belt cp and after i buy a new motor and esc....well and a new tx
(still on the stock tx)im buying the hdx superframe and then so on and so.

Now I found the minor faults in arf assembly

http://www.helifreak.com/attachment.php?attachmentid=50180&stc=1&d=1212532878

Ok time to disassemble the whole thing for a building log and "locking tight" those nuts and bolts this is going to require my nr 2 glasses

The top frame needs some work

http://www.helifreak.com/attachment.php?attachmentid=50182&stc=1&d=1212532878

Black = drill out with 2.5 drill
Red = slotted 1mm backwards ( will explain later)

Continiued
Ive viewed on this forum that someone had problems with the play between tail gear and main gear in this (http://www.helifreak.com/showthread.php?t=51675&highlight=copterx+tail+gear) thread so I slotted the fixings of the main shaft mounts so I can reduce the play between autorotationgear and tail gear

This is the play I have now (perfect)

[mnwizard]

Nice work Ber!

I like it.

[kgfly]

Nice detailed build log with good photos.

I wonder how you will be able to replace the main shaft bearings now that you have epoxied the holders to the frames ? Or replace the frames for that matter ?

[Ber60]

They are epoxied only on the outside , easy to remove

[another_finn]

Looks great, and I like your idea about adjustable tail gear mesh. I just might rebuild the stubby on one of these when I eventually crash the Guru-Z beyond repair ;)

[Jonnyheli]

Guys, I want to get a lama v3 for those windy days so I can have fun indoors.
My only problem is that I think I will have soo much fun that my belt cp will start to go dusty up on my shelf...? What you guys think?

[DierWolf]

Get the Walkera 4#3 (not the coaxial) the teenie tiny Fixed pitch they are great! and you'll continue your learning curve at the same time.

ps didnt have mesh issues with the Exi ;)

I have looked at them but they are more expensive. I didn't really want to go over £60.

Don't worry about the Belt getting dusty, after being confined indoors with the Lama you will be happy to get back outside with the Belt, if for no other reason than to hear those blades wind up! (The co-axes are pretty quiet)

If the V3 is all you can afford, it is a fine heli. I have several of them, and they're great for hovering around the house while waiting for parts for the Belt! :lol:

If you do get one, look for the 2.4MHz. You can get them for the same price as the older ones and it doesn't need the long antenna hanging off it. Also the 2.4 has the newest digital Esky servos which are noticeably more responsive than the older ones. These are also the same servos as the ones on the Belt. Unless you have the older analog ones on your Belt.

Cheers for the advice :D If I get one I will look for the 2.4Mhz one with the digital servos :D

GHz, guys, GHz. It's only off by a factor of 1,000 ;)

Looks like everyone's trying to get rid of the old 35/72 MHz versions, so there are some good deals around while supplies last. I'd still get the 2.4 GHz version, if only to avoid adding to the pile of useless 0404s...

Omg I cant believe I said Mhz:( Sorry guys, I am a disgrace to this hobby:( I even have a spektrum lol and I still got it wrong.:arggg::bawl:DOH

Erwin, you beat me!!!!!!!! My glasses are only strength 3.5!!!!!!!!!!!
How have you got on setting your copterx head? The flybar is shorter than the Belt and Trex, and I tried it with normal Trex paddles - very responsive - and the bigger Trex paddles which made it feel more stable.

[DierWolf]

I dont think 75 and 35 mhz will ever go away...

Some of the best and full featured Multi channel units flown by scale modelers (you know those huge radio's with a million switches and costs you your first born child) are still very very big and thats what these people prefer for many many reasons... I am one of them.

like this 1400 dollar 12 channel radio right here.
http://image2-5.rcuniverse.com/e1/art/kits/transmitter-174.jpg

Also boaters will always use 75 as 2.4 Ghz doenst work very well eye level over water, its just the nature of how the frequency works... I had a 2.4 radio for my boat and it was horrible and eventually ended up turning my boat into a pile of fiberglass bits.

Also, the big boys like Curtis Youngblood, GORDIE MEADE, ALEX RODRIGUEZ, MIKE TRUEBLOOD etc etc etc All use 75Mhz radios on their Gas and Nitro Heli's namely JR 10X, Futaba 14mz, Futaba 9Z respectively... Why? because 2.4Ghz has blind spots and sufferes alot from Vibration

So i doubt very very highly they will phase out 75Mhz... if any will try and replace 75 or 35 Mhz it would be 5.8Ghz Equipment, which has a much much cleaner signal.

[another_finn]

LOL! False alarm, Mark - you can get off the soap box for now. Just talking about 35/72 MHz Lamas being on sale because everybody's making room for the 2.4 GHz versions :D

[kgfly]

Hmm, those over-priced high end radios are all module-based so can be run on 2.4GHz too if you so choose.

I am sure a list of equally notable folk who fly 2.4GHz in large scale, expensive, high-performance models could be presented, such lists do not prove much IMO. Both the new 2.4GHz and the legacy FM technologies work well enough for sponsored pilots to use in line with their contracts and their preferences.

I have never heard of mechanical vibration being more of a problem for 2.4GHz electronics than older FM gear, can you provide any references ?

Can you explain why you think 5.8GHz is "cleaner" ? Do you mean fewer background noise sources compared to the .24GHz ISM band ? Certainly the shorter wavelength means even more shadowing and multipath issues than 2.4GHz and will require more strict diversity solutions.

Hi Mike
The +4 is only for the smallest screws. The head was a joy to setup the only thing was that I forgot to do a good setup I had to redo it 4 times before it came all back. Currently I am waiting to order a scorpion esc and motor because I seem to have fried mine.But hey new stuff is always exiting :cheers

[DierWolf]

Wow now i will have to go and gather all my 2.4Ghz vs 5.8Ghz information LOL... I come from a long line of Wireless internet people and i know why 5.8 is much better and much more reliable than 2.4.

Its like asking me why i feel 2.4ghz cordless phones are better than 900Mhz Cordless phones. (They are not btw, 900mhz outperforms them, do a search on why, you may find yourself suprised your 2.4ghz radio's are
doing the same thing)

But here's the short and nasty of it all... If you into anything Wi-Fi you should know this.

The 5GHz bands have much greater spectrum available and there are 12 non-overlapping channels, each with 20MHz of bandwidth. This means significantly better performance as compared to the 2.4GHz band.

The entire 2.4GHz band is 80MHz wide, which only allows three non-overlapping channels. If high performance is an important requirement, then lean toward the 5GHz band.

Everyone with these new 2.4Ghz radio's feel they are pretty safe, thats because you dont see the real problem with 2.4.. Me as a Wi-Fi guru knows all about it.... you maybe fly with 5,6 7 i dont care its not much people flying at exactly the same time, get yourself a group of 20 guys and you all fire up your stuff and start flying about for a while and let me know.

Like i said numerous times, this may not be the problem for you guys as you dont have tons of 2.4Ghz equipment around you, this is not the case on my tiny island. Which is why i prefer FM radio's

As for Vibration and Blindspot problems of 2.4 recievers its as easy as a search on Helifreak or Google.

For instance 2.4Ghz cannot penetrate carbon Fiber and has problems also with Aluminum frames causing blind spots...

As for vibration its a simple look in the manual of a 2.4Ghz radio.


“The receiver contains precision electronic parts. It is the most delicate radio component on-board the model and should be protected from vibration, shock and temperature extremes.”


We can go on and on about this but i wount you asked why i feel 5.8 is better than 2.4 and i have already listed the reason why.

[Ian 777]

Erwin your heli looks very very nice I may well get one:)

[mnwizard]

Hey D, after reading your last post here I got curious and started messing around with one of my 2.4s and while I didn't run into a problem with my heli, I did discover that the TX will cause glitches on one of the wireless laptops in the house. After some messing around and noticing that all the wireless machines were affected, I finally tracked it down to the wireless access point. The Tx was messing with the transmissions from the access point.

Hmmm... I have to believe that the opposite could also be true, that the access point transmitting could mess with my Tx.

I've been flying one of my Lamas around the access point while my kids are on line with the laptops. No noticeable glitchs, but it still makes me wonder....
