Tutorial - CopterX head on Belt CP

[wannahover]

hey do you guys think that i should wait till my align main shafts get here to put in the copterx head or is the x shaft just as good? got my head and tail combo today so getting ready to install

[nasukaren]

The CopterX shafts are a bit soft but they're otherwise fine -- and much better than the BCP ones! So go ahead and use it, and just replace it when you hit something and it noodles.

are the belts the same length?

[nasukaren]

They are the same length but apparently the tooth count (TPI) is slightly off. So you'll find yourself wearing down your stock OEM BCP front pulley a lot, until you replace it with a CopterX / Align part.

Man this thing is whoopin me. I ran into the samething as picasso did with the tail being extremely tight!! finally got it. Workin on the link length today. Has anyone noticed any probs with the head if you run the bcp fly bar being loose? also got to figure out how i want to move th AR bracket to the front!

[nasukaren]

Easiest thing to do is to get a swash with an AR bracket hole in the rear, like this:

Then you don't have to move your AR bracket at all. Only problem is that it costs $19.

the AR bracket, what i did is put it as far in the top corner as possible, with about 2 mm from each edge. i made the screw holes by pulling one of the head swash guide bars out of the original belt cp head, it pulled right out, then heated one end of the bar till red w/lighter, holding it with needle nose, and used it to make my starter holes for the AR bracket. worked like a charm, it melted easily through the belt plastic frame. no mess either..you could even use a needle, just keep it straight.

i just got my scorpion -8 V2 motor & 45A remote ESC in to day, man that is a sweet set up... i cant wait to get it programed and into the air...good luck on your up grades.

oh yea, if you find your not getting enough pitch range with the copX main shaft, the belt cp main is 2mm longer (hole distance), all you have to do is grind the head end down 3mm (shorten the shaft) so it doesnt interfere w/the flybar, but you gain 2mm in pitch room... thats what i did and i get +/- 11.5 pitch range...

good luck

picasso, karen,

thanks guys for your help and tips!!! well i dont know about pitch but got my link length done and swash, washout level and at idle up full positive and full negative it does not hit anywhere that i can see left, right, forward and back. picasso did you have to file the ar pin at all for the link to clear??

[picasso]

yep, i had to bow the inside of the bottom with a small round grinding cylinder (dremel = lifesaver) and then set it tilting slightly forward.. just becareful it weakens the bottom bar so when installing use needle nose to hold the square ends of the ar when screwing into the frame so the ends done twist off...you'll see what i mean... but once it is in there is no stress on it, its just a guide..

[chrscoop]

just got my copterx head and tail. should i use belt cp main shaft or copterx one and should i use copterx belt or stock esky one

[wannahover]

chrscoop- well i can say being as i am just finishing up that both will work its just a matter of the work you want to do. Myself i just flipped the copterx main and used it but is shorter so you will have to do link adjusting on the swash. the esk ones works but needs trimmed so not to hit fly bar. i used the esky belt as karen said that the teeth per inch is diff from esky and would probaly wear the gear. the esky belt seemed to mesh good with the copterx tail for me.

[wannahover]

as far as just the shaft gose my personal opinion is go with the copterx as the esky tend to suck! Soft and not straight even from factory(my experiance)

[chrscoop]

Thanks allot for your help. done dts mod, now cant wait to get this mod done, everyone says it,s much better than stock.

Thanks Again

You might as well use your CopterX shaft since you'll be buying them (or Align) as replacements and it makes sense to set your head up once with the Copter X + shaft and forget about it. If you switch back to the BCP shaft, you may have to reset your head settings.

Re: belt. You might as well use up your stock esky one if your front pulley is esky. I find that the slight diff in TPI between the two eats up the plastic front pulleys if you use the copter X belt. Once you've destroyed your front pulley, replace with an align compatible metal one (such as the one below) and then use the copter x belt. Note that you can't use the Align front tail gear + pulley setup as the BCP has a different tail gear ratio; so you need to take the pulley below and attach it to the BCP tail gear shaft using the grub screws provided.

just my 2 yen.

[chrscoop]

thanks i've just ordered these tail pullys. i take all i have to do is take off the esky plastic one and replace it these

cheers

chris

[nasukaren]

Yup, that's why I chose them. They're great!

Karen

p.s. the one on the left in the photo above is for the front pulley, the one on the right is for your tail pulley, but it might not fit in your tail cage.

[chrscoop]

Which one is which you put left on both of them.

[wannahover]

here is my belt. DONE FINALLY! welcome all feedback good or bad.

[chrscoop]

your belt looks cool. i have gone for a trex canopy as they come with more designs. still a working progress, waiting for flybar paddles and tail blades to turn up.


does the trex tail boom fit on belt without modding.

Belt Cp: DTS mod, copterx head and tail, esky 0704b hh gyro, align 325 fiber blades, sg90 tail servo, trex fiber glass canopy.

[wannahover]

Nice! ya im waiting for my credit card billing cycle for my canopy. yea the tail boom that i got (not sure of the part#) was just slightly shorter so i just pulled it away from the frame til i got the belt tension i wanted. i just used my belt tail blades for now.
