Hey all,

Iwas given a heli yesterday, and for the life of me, Ido not know what it is. It has a mix of spektrum and e flight servo's and an eflight gyro, spektrum tail servo, heli max motor, and an all metal frame (head is all metal too, but he said that was upgraded).

Iknow the electronics dont really matter, but im just at a loss as to what this heli is.

Here are some pictures, maybe someone can clue me in some.

My guess is that it's a real align trex. It's an older model, before the S, SE, SE V2's came out. I can tell be the design of how the servo's are hooked up. I don't believe there were any clones or other very similar looking 450's at the time. The entire tail (everything behind the gyro) is what made me instantly believe it's a rex. Align hasn't changed that design on the 450's with the exception of the torque tube tails.

You're trying to get it into the air, right? Is everything that you have in the pictures?

In that case, you appear to still need:

- Set of main blades, order spare's too lol [link=http://www.eboyztoyz.net/index.php?op=showitem&sku=7947]This is what I would recommend[/link]
- Batteries - 3 cell (11.1V) 1800-2200mah [link=http://hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=7635]This is what I would recommend[/link]
- Transmitter (Do some research, this is harder to recommend, you get what you pay for up to virtually glitch free)
- Receiver (One that's compatible with the transmitter)

Thanks for the info. Iam aware of what it needs to fly, and Iwill use my DX6i for the transmitter, and I plan on using the Spektrum AR6100e receiver. Iwill wait for a few weeks though, as Ijust got a job at my local hobby shop and im going to wait until my discount kicks in

Iappreciate the info very much.

Ireceived some more information on this helli, and its a ARC 400, or sometimes called X400.

Here is a pic Ifound, and it matches mine exactly (though mine has the fully upgraded head)

it's the former heli max 400 that now arc 400.

It has been answered but it is a Helimax MX-400, Do not use the blades recommended above in the link. 325's are too long this is not a 450 size - heli it's a 400 size heli. Check my profile - gallery and search the "MX-400 Purchase" thread I made along time ago.
It was a great heli.
You can still get the Helimax 400 helis but only as overruns and back room discounts. Helimax now promotes the Axe 400 instead.

You can still purchase parts from the foreign web based sources for the Helimax 400 under the X400 classification. For some reason, x400 parts seel for cheaper than Helimax 400.
Go figure. Tower hobbies is still selling 400 parts as one location for you. Also Check out Grandrc.com for the X400 parts.

No, Align Trex parts wont fit. Don't try its a waste of time unless you had the MX450 ccpm version. You dont, you have the mechanical mix.
Loose the helimax motor, seriously it overheats very quickly. I went with the Trex 430 motor back then and it was a great improvement
Its a great helicopter. I still have mine, Just collects dust now though as I went to 450 rex class stuff.
You can also go to the RCU videos, type in MX400 and MY video of the 4th day ever flying an electric heli with the 400. Fun stuff

Have fun with it, but keep in mind - becoming obsolete and you can actually purchase a clone 450 size heli complete frame kit for less than the cost of a couple of x400 parts.
IE: exi450 trex clone.

Later!!!

Thanks.

Im not dumping money into it, and will just get a trex 450 clone instead. Imay just throw a set of cheap blades on this one, and put it on display
