Yes, I know this doesn't really go along with trex but the exi 450 is a clone pretty much. Anyways what electronics should I use.
Thanks

hs65mg's cyclic
gy401/9650 on tail

your choice of motor and esc.

paynezoo

What about hs-55 or are they to weak.
Also what would a be a good motor.

Paynezoo, I have the exi 450. I'm using Spektrum DX-6 RX and TX. I have the spektrum servos at this time. I have some HS-55 I'm thinking about using until I can get the HS-56. I'm running the Align 430L 3550 brushless motor.

paynezoo

O thanks, geeze, I'm trying to keep it on a low budget. I hope the hs-55 will hold up or is it really worth it to get the hs-65.
What is better and why. And how does that exi fly?

The HS-65 's are definately worth the extra $$. I initially set mine up with E-Flite S-75 servos. The Hitec servos make it fly so much smoother and precise. It is definately noticable and from my side of the fence , was worth the extra money. It does fly with the smaller stuff though.
I use an align 430L 3550Kv motor / 12 tooth pinion , 35 Amp Align ESC and an Align Gyro. The tail servo is the Hitec 5084 that came with the gyro.
I will be upgrading the Gyro in the future to either a 401 or logitec. The align gyro works well about 90 % of the time , but does drift. It is an annoyance to me at this point , but not a show stopper.
I also put 8.5 g align paddles and Align wood blades ( 325 pro ) on it. The paddles made it more stable.It also has 1 weight per side all the way up against the paddle.
Just FYI - I am still just hovering and playing around , no FF except for out and back ,tail in.
This morning before work , I flew it , no wind and had both fat thumbs off of the sticks for about 10 seconds and it just hung there. I would almost venture to say that it is easier to hover around than my CX-2 , once it is off the ground.

hs-55 are weak. they will strip easy in a crash. do yourself a favor and get the hs65mg's and avoid the frustration from the get go. i've had my hs65mg's for a long time with plenty of crashes and they work as if they're still brand new. pay the money up front or deal with the hassle down the road.

for motor get the JustGoFly 450F brushless motor. i've tried many different motors and this is simply the best one i've had.
for esc get the align blx 35a esc. has good soft start and decent built-in bec and generally reliable.

some people run with the telebee gyro but skip the cheap stuff and go for the gy401 or the logitech 2100t.

how well your exi 450 flys depends on how much money you spend on the eletronics. if you get the cheap stuff it will fly like a cheap bird. if you put good quality components in it you'll get a bird that flys like a trex or better.

Check this out....[link=http://shop.tomsrc.com/index.php?cPath=76]TomsRC[/link]. You can buy servos in 2 or 3 packs to save money. It is only $2.95 for shipping too...I am using the HS65HB's instead of the MG's and absolutely love them. I am not a 3D maniac and they are perfect for how i fly..They have the karbonite gears and have less slop than the metal geared MG's. Hitec has to purposely manufacture the metal geared servos with a little slop or the gears would grind and wear out prematurely. I crashed str8 on the head from 30' post-hole-digger style and the gears were perfectly fine. The servo's make the heli feel like it is part of you when set up correctly and are totally worth the money....

my cent...

Thanks, what is the different between the HBs and the MGs?
Also what about this alpha 400 motor that xheli recommends and the volcano 30 amp esc?

noobflyer01

hb's are carbonate gears ( type of plastic) mg's are metal. so you can already guess which one's are going to be more durable.

i've never tried that motor or esc but i wouldnt trust it. go with something mainstream.

paynezoo

Its only 30 bucks it dosnt look so great. The 430l motor is kinda pricey do you have any motors in mind that wont be as expensive but still good.

dude7422

try this place for motors http://www.hobbycity.com/hobbycity/store/uh_index.asp the big name brand stuff is just a sticker any more none are made in us any more

paynezoo

Ok I think I got it my setup...
-x3 hs-65s
-hs-81
-430l
-dx6i
-35 amp esc
and I don't know what gyro yet, something under $100

noobflyer01

I went with the JustGoFly 450F motor. its 55 bucks but worth every penny. its one efficient and powerful motor. just try out different pinions for desired headspeed.

here's my exi maiden flight with the JGF motor with the telebee gyro. http://www.youtube.com/watch?v=RXvoBBHK5H4 i had to land because the tail wasnt holding. the belt was too lose and the gyro wasnt setup correctly yet. i replaced that gyro with the gy401 and havent looked back since.

paynezoo

Well the gy401 it $40 more than the 2100t so is that a better gyro. O and in the exi 450 when it comes was it already setup without the electronics or did you have to build it yourself.
Also not to get off subject but how do you get that sweet paintjob and where would you get stencils for it

noobflyer01

the gy401 is alot easier to setup. i got mine from xheli barebones. i had to buy each part and set it up myself. when you get yours you'll find that its 95% preassembled. only thing you gotta bolt on is the landing skids.
just make sure when you get it that you go over the entire helicopter and check every screw. loc-tite the screws that goes into metal. use blue loc-tite. make sure you loc-tite the screws that bolts down the blade grips to the spindle shaft.
setup is identical to the trex450 manual. i have a trex450sa also and the setup is identical. google trex450sa manual and you're golden.
the paint job was an airbrush assignment for my brother. i think he did a good job on that one. i'm starting to design a few personal canopy design as well.

Just received an EXI 450 and WOW! For $59 shipped it came with a mostly metal head that has no slop and plastic blades that look servicable for mild flight. The metal frame is nice also and doesn't have burrs or sharp edges to cause problems with the wiring. The plastic tail assembly is just like the one that came on my Comet 500 and that one works great with a 9257 servo and the gyro from xmseller. I am going to outfit this heli with HS65hbs and the JG 450 motor from hobbycity.
It should be a great flying heli!

paynezoo

WOW WAIT...$59 bucks what website did you order that thing off of. The lowest price I found it was $99 with shipping
O and do you need a airbrush cant you just spraypaint it with paint that sticks to plastic.

babyhuey

They are $89 now. They had a black friday sale for $54 shipped and Sat. they were $59 shipped on Xheli.com. This thing is well worth $89 and the SE version is like $169.

paynezoo

Darn the olny day I didn't look a xheli was on the day black friday[sm=punching.gif] Im hopeing to get it on christmas it better go down in price of else I would waited an extra month.
What gyro are you talking about too
And still do you need an airbrush to paint a canopy or can you use a spraypaint.

babyhuey

The gyro that I am using is sold by xmseller on ebay. They have two versions, one is newer and can be used with a digital servo and I currently have both. The digital one works fantastic with a futaba 9257 servo. The other one has some drift with a standard servo. They are both simillar to the Telebee gyro. Hobbyking has one that looks just like it for less than $40 and it has gotten good reviews.
As far as painting goes you can use a spray can and it will work well if you go through the proper steps of preparation but an airbrush can give a wilder more professional paint job.

paynezoo

What servo should I use for the tail
I was thinking the hs-81

noobflyer01

for tail go with the futuba s9650 digital servo. and if you running on the gy401 than your tail is rock solid.

paynezoo

Ok cool. What cell battery and charger would I need?

aythomps

paynezoo, there some nice lipo on hobbycity site for low cost like the zippy. I got some of mystery lipo that works well at 11.1v 2200mah.
