Hi:
I am just about to buy the T-rex 450SA ARF version which includes only the T-Rex and a Brushless and Esc $269.99 Package.
I'd like to know if any of you have bought the same package and what kind of components did you use.
Purpose here is to save some money and have a great flying electric heli.
Thanks.
Alfred.

I didnt get it myself but some guys in my club did. they got the algin gyro for them also along with some Hs-65 servos ( well that was supposed to the guy who odered messed up)

they seems to all fly nice, none of the guys can fly them yet, just hovering around a little bit.

I forgot to mention that I already have a JR8103 DT heli version which I am planning to use, but I need to know which receiver could do it fine with it.
Another thing that I need to ask is if I need to power the servos and receiver with a different battery pack than the one that powers the motor or should I use a voltage reduction?
Thanks.

Great C5m7b4:
It look like we are starting to save some bucks.
Thanks.

They dont post the price until you add it to your card and it was pristine when I got it. I am using a Gy401 gyro and I have the ar6200 rx to go with the DX7 that I already had (and I love it), and I just picked up a JR perfomance mini heli servo set with three DS285 servos for the cyclic and one DS3400G digital servo for the tail. I paid like 150 for all 4 servos. the part number is JRPF300H. I love my setup and in all it was pretty cheap..

212.00 for SA
150 for servos
137.00 for gyro
45.00 for rx
total bill comes to 544.00

Not too bad for a T-Rex...

Get a JR 770pcm or 790pcm receiver. Get 3 HS65HB or MGs get a Futaba 401 gyro and a Futaba 9650 tail servo. Or get the JR mini heli servo set (3 285 and a 3400G) but still get the Futaba 401 gyro. I haven't had any problems with the BEC in the Align 35X or G ESC running the four servos and the gyro.

Are you obtaining the power from the main battery for all components? Sorry but I am new into electric flight. What is the BEC purpose?

One more question would be how much experience do you have with Helis. I was getting pretty frustrated trying to fly the Blade CP Pro but I wanted to give it one last shot and buy a T-Rex. That is why I went with the SA (price) and that is why I did not buy the most expensive servos out there. The 285 seem to be perfectly good for me. I am just hovering and getting into a little bit of forward flight now. I have 13 flights on this Rex and I love it. I could already barely hover for a while, but with just only 13 flights, I can hover a whole battery, I can do two are three piros at about 4 feet off the ground and I have been flying around my yard. I have gotten good at left and right hovering as well. the T-Rex makes learning to fly extrememly easy if you are anal about your setup.

Good luck and save, save, save, but remember you get what you pay for so dont get some S75 servos or something cheap like that or you will probably be sorry,

Yep, all components will be powered by one battery. The larger the mAH, the longer you can fly. Be very careful with these things though, they can be dangerous. You need an 11.1 volt with around 2100 or 2200 mAH. Get a good BALANCING charger or get a Blinkie that will balance the cells. there are three cells in these type of batteries and if you overcharge one of the cells, it can catch on fire.

You are going to hook the battery up to the ESC ( Electric Speed Control) and then that will supply the proper voltage to the motor because it has a BEC (Battery eliminator Circuit) or something like that.

Looks like I am following your steps, I currently have the Blade CP pro but this little thing is hard to hover because of a not very much responsive tail or responsive in excess, any way, now I am steping up to a Trex but I will set it up like you, I am not a great heli flier I have 1 month experience and I almost can hover sucesfully my CP pro. I put my eyes on the T-rex because many people in these forums claim that this heli is very much stable and is good for beginners. I'd like to spend a fair quantity of money and have a fun heli, maybe later as my skills grow I could upgrade it.
I am taking notes of what you guys suggest. Thanks in advance. The local hobby shop carries the t-rex I will talk to them to know if I can have a good deal (Under the normal price) or go directly to the internet store that you just recommended, I'd like to know how much do they charge for shipping, that will give me a good idea on where to buy it.

ground was calculated at 9.50 and and usps was estimated at 17.25. Not a bad deal at all. I had to wait a little longer than I would have liked for it to show up, but it was worth the wait. the first time that I spooled it up, it scared me. Really slowly I upped the throttle and when it lifted off the ground, it came almost straight up. I could not believe it. Just a little bit of trim and I havent touched the settings since except for a minor change in the throttle curves. 13 total flight so far, piros, and a little forward flight. right and left side hovering, but still working on the nose in.
These things are beautiful. Watch the finless videos for the setup and you will be in great shape!!!!

Just my 2 cents but the Jr mini pack is top shelf and the 3400 works great with the Futaba 401.
