Need some things cleared up!
1. Is the T-Rex considered a micro helli?
2. I understand that most people would recommend a 30 or 50 size nitro for a beginner,,,,,,,,, I'm I doomed if I go with a T-Rex for my first?

i havent been in touch with the trex scene for a little bit, i will try and point out what i feel are the important differences.

trex can fly pretty much anywhere, but for a beginner is wind limited due to its size. parts are cheap as hell so you can crash comfortably. if you can get it to fly nice like its nitro's bigger brothers thats a definate plus, regardless of this flying it would probably set you ahead of the curve for flying the bigger and more stable flying nitro's. also with a small helicopter like this, distance is your enemy, its already small then you go and throw it a few hundred feet in the air

personally i would reccomend a nitro ship, probably 50 because you will grow into that fast and performance will great for you, for a long time. it will be stable, and it has a very large performance range in 3d flying. bad part about nitros though, theyre messy ie cleaning, unless you have a large amount of property where you can fly in your front or back yard SAFELY; its probably better you go to a club or local flying spot, and costs of fuel are more over a rechargable lithium battery in the long run.

-on a side note, i wouldnt give up my nitro machines for anything in the world i love everything about them, the smell, the mess and cleaning. the social activities required by going to a field where other locals fly etc.
I'm I doomed if I go with a T-Rex for my first?
definately not. there are MANY "performance mods" that people have done, that make these things fly incredible*, and if you have the time and money to do that you will be very successful with them. most of the nitro's come pretty much ready to roll after assembly.

*disclaimer: im still under the impression no kit/stock trex flies top notch out of the box, i could be very wrong, and someone with more knowledge on it im sure will speak up.

It all depends on your situation…Nitros have limitations in terms of places and requirements to fly(club, AMA, insurance, winter season, etc). On the other hand they’re more stable for beginners. The T-Rex is one of the most popular electric in the market right now. I’ve always consider micro those with fix pitch. The T-rex is bigger and more complex. Check the Rex forum maybe it will help you decide…

Thanks for the replys.......I flew a Rappy 30 a few years ago, well I could hover it ! Anyway, I didn't like the mess nor the fact that you almost needed to travel all the time to fly. I was hoping that the Trex could be flown in my yard with out all the flight box stuff! What is the e-raptor all about? Can't seem to find much about it, Can you buy an e-raptor or is it a conversion?

without question. if you search around the t-rex forums you will see many people using a case, that holds all of there t-rex stuff, batteries, charger, tx, helicopter, everything. most of them you can travel with too and take on vacation, with you on business trips etc all in one box.

to top it off, they require a fraction of the space that a nitro would, and short of dust almost never need extensive cleaning. if you get a well set up trex you will be very happy.

You're not doomed if you choose a T-Rex as your first heli...

but, you will spend a lot of time tinkering to get a proper motor and pinion combination -- if you look over in the T-Rex forum, there are a million different combinations to try. If you look carefully, you'll see what seems to work well in most situations.

You may spend quite a bit of time trying to solve blade tracking problems, radio glitches, tail-wag problems, ESC overheating, cutting out, or governor problems. This is not productive learning-to-fly air time.

You'll need a good supply of expensive battery packs to do any serious stick time as you learn to fly. For a ten minute flight, you'll need anywhere from an hour to an hour-and-a-half to recharge that pack before it can be used again. That doesn't count the time it takes for the pack to cool down a bit before recharging.

The T-Rex is small, and VERY quick. It will not only react to control inputs much faster, it covers a lot of space in a very short amount of time. Don't kid yourself into thinking the T-Rex is a "front or back yard flyer" unless you have some serious room in that front or back yard. Not as much as needed for a "nitro" powered ship, but just the same, it does take more room than the average yard unless you only want to hover.

If you need to go out and buy a T-Rex, the motor, radio, gyro, ESC, battery packs, chargers ... and all the other stuff to get one actually flying, you'll spend about the same amount of money that you would have if you had picked up a Raptor or Caliber 30 nitro heli for the first time. Expect to spend $700 - $800 on your first one. The initial investment required to "get into" a T-Rex is NOT trivial. It is some serious money.

As for not having to have insurance (AMA or otherwise) when flying a T-Rex (or any type of aircraft) in your yard, that's not a sensible position to take. If you don't think a T-Rex can do damage, then by all means, get the head turning at 2400 - 3000 RPM (common RPM for a T-Rex head) and stick your hand into the rotor disc (not recommended unless you don't like your hand in the first place). Maybe then you'll think twice before you fly without insurance. Neighbors can turn mighty mean if you whack one of their kids, pets, or some "prized possession" with your "toy helicopter".

The T-Rex is very popular, I own two myself. I find them a blast to fly. Looking back at all the helis I've owned, I'm not convinced I would have chosen a T-Rex as my first ever heli....

Sprite --

I think that's a pretty accurate statement. The one exception may be the new SE T-Rex which is a fully "blinged out" T-Rex. CF frames, CNC parts everywhere...and a list price of $540, to which you still need to add radio, gyro, batteries, charger....this can push your initial investment well over $1000 dollars for a T-Rex. As such, the repair costs go up with this kit, as you no longer buy the cheaper plastic parts, you replace the CF with CF and the CNC with CNC (or you don't have an SE anymore).

But some of the reports on the new SE tend to indicate that some of the underlying T-Rex problems are still there - tracking, wagging, varying degrees of quality control...

The control linkages on the T-Rex requires some massaging due to the fact that the plastic ball links randomly fit loose, tight, or OK. The canopy tends to interfere with the control system, as well. Unless you dismantle the swashplate before you build the kit, clean it, then reassemble it yourself using a decent glue, you run a good chance that the swash will disassemble itself in flight, always with a bad outcome!

The T-Rex is a pretty good chopper once you get the bugs of your particular machine ironed out. It's just that sometimes, you spend a lot of time with the iron, and that's time you're NOT spending flying.

yea thats what i figured but i didnt want a foot in mouth problem if i said the wrong thing

and at that price, your practically into a 50size with engine. that being said im sure i will end up with an SE just for kicks =] as i said ive been out of it for quite a while, trying to focus on nitro's and getting my sh!t together. finally had my t-rex set up for me as i dont have the time, or rather want to spend the time doing said tuning because as you said, i would rather be flying.

the t-rex looks like a great machine once you get it dialed in and purring, at this point i havent experience that. i really hope to however and im keeping positive about it, and hopefully soon it will do me right.

My first heli is a t-rex and I think its great it is considered a micro. Its good for learning because if you crash it will less expensive. Also when set up right it is stable.

Then you actually have no reference point as to how well the T-Rex might be suited for a first-timer when compared to the rest of the heli market....

Cheap parts do not always equal great beginner's helis....

t rex

hi i have had helis for a few year .. i started with a moskito 50 ..

but 2 months ago is was showing my brotherin law .my md500
flying and he said he wanted a heli .
i told him to buy a 30 size ..but no he went and bought a t.rex ...
after setting the heli up for him he went for his first flight ..
after tipping it over a few times .. we made a trainning under carrage from ..2 bits of dowl and 4 ping pong balls ..
with this fitted he lernt to fly in a few days .without breaking any thing else..

he has now been flying the heli without the tranning gear for a few weeks and he is onto fig eights .....

but i think for a new flyer the t.rex is to much to handel ..so get yourself a slow .heli ..30/50 size .. i still love my moskito ..it flys so slow .its even easy to work on .. have enclosed link to my pic gallery ..

Just so you know - the link to your gallery is right there after the last line of your post (every post). It isn't necessary to do special work to put the link in your post.

TREX SE - JGF450TH - 14 t - TP2100 prolites - CC35 - HS56 - 401 + HS50 is the best choice. You wont regret it.

i learned the hard way went to a nitro heli first and i put more money into it with parts than the heli cost . i own a trex and it is a really nice flying heli and the parts are cheep. really take your time on assembly of the helicoptor it really pays off in the end of how your heli flys. also another option is to learn on a sim like G3 or reflex.

How about for outside?

Must have started our post at the same time.
How is the T-rex in a 5-10mph wind? To much a handful for a beginner?
Will have 30+ hours of sim time with a 30size before attempting to fly the real thing. Want it to be fun. Am I crazy for wanting to take a T-rex out in these winds?

The T-Rex will fly in wind, but it will definitely keep you on your toes while doing so. It is nowhere near as stable in the wind as any of its larger cousins.

Having begun with a 50 size, and still enjoying every flight.
And having a Hummingbird v3 FP, with a Rexy on the way.
Big one seems almost too docile now.
Still glad the guys on RR talked me into the nitro.
Theres alot to do before flying, I went the sim route.
Aerofly, then XTR with my radio.
Save's you some heartache, for certain.
