My MX400 after the latest overhaul ! can i please get your input

[whattheheli]

here is my newly rebuilt MX400 i would just like some input on if you guys see anything that you think need to be changed or anything thanks guys !

Good looking set up. I didn't think the ring was nessary with the Dx7 ?

whattheheli;

I would strongly suggest to move the gyro. In a crash, the flybar will hit it and destroy it. A good spot would be behind your receiver.

I like your machine. Do you know how it compares to the Align 450?

the align 450 is a better heli ! you would have to do much less moding to it than a mx400

[whattheheli]

ok so i made one more mod last night ! i put in a align 430xl i wonder if i would be ok with the cc25 esc running on this settup ! i have a 14t pinion on it thanks

[Scottlclem]

I would be curious to know if your cc25 will run the 430xl myself. I was debating on buying one 430xl and went with the Just Go Fly 500th because it's full load amps was a little less then the 430xl.
I'm guessing if your like me your going to try it and see what it does . If your gona try it set the overload in the esc to it's max setting but not turned off,hover it bit land and take temp reading or feel the esc.

wtf is a jesus bolt?

[super coop]

the bolt that holds the hub to the main shaft is called the Jesus bolt
stems from fullsize helis
if it fails your going down like a flying brick, an you may get to meet him!

[Scottlclem]

I heard it was called Jesus bolt because if it ever comes out in flight you will know why the call it a Jesus bolt. It's the bolt that is under the main gear that runs through the main shaft.

[istandalone]

gottcha. kinda like the "oh sh!t" handles on a car. once you use them, you know why they are called that.

[pam-mo]

I thought it was called the jesus bolt cause' if it failed only jesus could save you :-)

same thing but I like my version better :-)
I think I read it that way in a magazine or post.

aight, couple of questions for the thread starter. your battery tray, is that home-made or align? either way i like they way you've got it set up. also, the head, is that the eccpm conversion? one more thing, it looks like (in the rotorhead close-up) that there is metal shavings/filings on your swash? you really want to blow all of that grit out/off of the head before you fly her again. just think if just one of those shavings gets into your swash or main shaft bearing.

[whattheheli]

the battery tray is home made just took a stiff piece of plastic and one end to fit inside the frame rails ill take some pics when i get my mx450xs i will be moveing the electronics over to it as soon as i get it then rebuilding my original mx400 and yes it is a ccpm convert kit on it and i allready cleaned the swash up ! thanks for lookin out thou !

[istandalone]

no problem! i'd hate to have a fellow freak's heli fail because of a small piece of metal lol. you said your getting the mx450? check out tower's prices on the mx line. getting really cheap.

[whattheheli]

yea tower is where its comeing from my fatherinlaw ordered it for me for xmas

[istandalone]

sweet. are you getting the ultimate combo or just the arf and will build it to your own specs? if your getting the combo, stay away from that motor they offer with it, as it's pretty weak for as much juice as it draws. then again, maybe i've got to play with my pinions more.
