Whats what...?

[Indi]

hi i am new to this helicopter thing and iam under the impression that if you want to learn to fly helicopters then you need to have good kit. I went to a local rc gathering and the bloke got my heli off the ground no problem and said 'well it flys... a bit twitchy but it flys' . I was very put off by this i would rather he did not say anything.

OK you may be wondering i say this for one reason... I work on cars all day I am a technician for a major car manufacturer. If for example there was something wrong with a car say steering play for example i would not expect a person who was learning to drive to use this vehicle. the reason for this is because this person is learning to drive and needs an A1 vehicle so he/she can concentrate on learning to drive and not have to worry about the flaw in the vehicle.

So i have decided to put my hummingbird to one side and acquire a T-Rex 450 SE for two main reasons they being that i am new to this sport and need a machine that will perform beyond y expectations as a learner so i may concentrate on learning to fly instead of concentrating to fly a heli with its own problems such as head slop and flex in various key components.

I am convinced that what i am doing in right but am now faced with deciding which one to get.... shall i get the CDE or HDE version.

Your views on the above would help and if you know of any other versions that are out there your input on that would also be good. Just one thing more i was thinking of getting a complete kit radio gear and all and does anyone know if the aluminium case come with all models and if the heli fits in when built and if not what you have to dismantle...

sorry for this post being a big one i am new to this forum thing...

I have a Blade CP I'm trying to master so that I can justify a Trex XL or SE. I'll answer the difference between the CDE and HDE. The CDE uses the computer transmitter to set up the mixing. HDE does it mechanically and I believe uses fewer servos. The CDE takes Three servos. It appears the CDE and computer radio is the way to go. You may get an arguement on this point. It's the way I'm going at any rate. The Trex also requires a gyro. Numerous models/makes are available, but the hot dog one is the Futaba 401 coupled with a Futaba digital servo. That combo is $219.

Here's a site that sells Trex

Here's a forum that talks about Trex
http://www.rcuniverse.com/forum/forumid_167/tt.htm

The consensus seems to be that these are very stable machines, parts are relatively cheap, and performance is good.

Hope this is a start!

Both use the same number of servos i own all versions of t-rex now you do not need a digital servo for the tail but GY 401 gyro is the best choise and you can use a nornal servo with it cde is more stable less links to the swash and less slop.

Ah! Thanks for clearing that up. Glad to hear you think the cde is more stable as that is the way I want to go. I have and Optic 6 radio, or I may get a DX6 2.4 ghz setup. Seems like there may be additional 2.4 radios coming out real soon.

Something i forgot to unswer.
The aluminum case comes with all but the 450x V2 and no t-rex does not fit in this case is very small. The aluminum case that t-rex fits in comes extra and in Greece costs around 100 euro it has space for the heli the TX and few spare parts and blades, it fit's as is you do not have to dismadle anything.
@cooperd
I use futaba T7cp on all

well thanks for that guys your info was very interesting but a went a little over my head... i was thinking about this kit in the link below what do you think....

http://www.heliguy.com/Electric-RC-H...COMPLETE-DEAL/


the guy in the local shop says that i can get the tx alot cheaper... what do you guys think...

have included the spec below incase thhe link is no good...

T-REX 450SE CDE
4430L 3550kv brushless
BL-35G ESC
325 PRO Rotor Blades
315 Carbon Rotor Blades
Hitec Eclipse 7 TX
RX crystal
RCE 500 (Headlock)
Electron 6 ch receiver
3 SG90 servo
1 SG50 servo
1800 mAh lipo (12C)
T connector and JST
Lipo charger

is it me or is a gyro lock seem like a jolly good idea to keep the tail in check....

Hi Indi.....welcome to Helis its a great hobby....well cool with plenty for everyone.

Your views are spot on, nobody wants to buy a peice of junk to fly....theres no point unless you like difficulties.

For shopping...try www.revolutionmodels.co.uk for the TRex....they seem cheaper to me and are a very good company to deal with. I think the ally case is a seperate item which is a shame....but I guess not everyone wants a case? Its a good touch.....imagine:

sinister looking figure, clad in black assualt gear, up on a block of flats....grimly opening an alloy box...carefully fits his weapon together....and off soars a TRex.....on a search and destroy mission!!!!!! oh well...I did try

Dont be put off LiPo stuff either.....its here to stay....it deserves respect and adherence to instructions.....the website I mentioned has a good warning about LiPo....with does and donts.
I have been giving serious thought about getting a TRex as well.....its the only electric heli I am drawn to.....I fly nitro otherwise.

Dont worry about long posts I blither on for ages sometimes......I must send people to sleep.

"Twitchy" is in the thumbs of the beholder...

I have heard people say, and seen people state on forums, that a TREX is "twitchy". Nonsense (at least in my opinion, for whatever that is worth).

"Twitchy" and "Wobble" seem to be buzz words these days.

The fixed pitch Hummingbird, and all of the micro-fixed pitch machines, will be less stable and have different response characteristics than a well set up mini (like the TREX or Shogun). These are straight Hiller steering with very light rotor systems and operate at relatively low rotor RPM.

At any rate, from what I have experienced so far, the TREX is very smooth, very steady, with very firm and proportional response to control inputs and much easier to fly than any of the micros. I have flown the CDE quite a bit, and to a very small degree, the SE. The SE flew better-good enough that I am now building one of those now too.

This does not mean to imply that the micros are not worthwhile or a lot of fun-they are. If you own a Hummingbird, fly it and enjoy it. If you want a TREX, go for it.
