After the last crash I'm not flying the blade any... I've been thinking about it and I really am not happy flying it as it is... Its a blade cp (original one), with brushed main and tail with 4n1 still...
I'm getting a dx7 soon and have been thinking about going brushless on the blade and just getting another reciever...
Heres the thing.. I like this heli but I don't love it... so what CHEAP options are there for brushless main motor and brushless tail... Gyro will be the telebee when itake it off the trex and upgrade it...
I'm not talking $5 motor or anything but speed controller and motor around $20 or so would be great.....
Thanks!

Not looking for extreme performance, but better than brushed motor and longer life..
and a fyi I really don't know anything about brushless motors....
But from what I've gathered would these be good choice?
What kinda pinion would I run?
Main motors
in order of what I speculate would be best..

why do the lower kv motors draw more amps? I figured they would be less cause they are less powerfull?
Here are the speed controllers depending on which motor..

And for the tail the only one I could find really was this..

using this speed controller
http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4204&Product_Name=TURNIGY_Plush_10amp_9gram__Speed_Cont roller
so if you figure about $15 for each item, for around $60 I could go brushless?
Which ones do you all think would work?
Would these even fit in a blade cp?
Would one motor be better than the other and why? Could I get longer flight times with one? I have no plan to even try to do 3d with this heli, just want it for basic sport style flying..
Thanks guys!
All help is appreciated!

using a $20 suppo from lightflight RC on my old cp ( now is my fathers) with a himac motor about 440 i belive.
check out my thread for tail mod fix. using a Gws and Mpi motor and gearbox its pretty simply cheap and works GREAT no need for a brushless tail my father has 12 hours on this tail and its working as well as day one... grr wish he had dun it while the Cp was still mine lol
