eventualy i will want to upgrade to brushless. what to i all need inorder to do that? "besides the motor and speedcontorler."

Motor ESC a JST Y connector and a Y harness servo connector

Check out the Hop Up section on the CP Pro at www.horizonhobby.com It shows everything youll need and what they recommend

i dont need to get a seperate gyro and rx for the blade cp?

i dont see the page

If youre converting your CP to a CP Pro then you also need to toss the 4 in 1. Buy the 3 in 1 and 6 ch RX. Theres a gyro already installed in the 3 and 1.

You can also keep your CP TX without having to buy the Pro TX. The only difference in the 2 TXs are the Pro has a knob for remotely adjusting the gain. It also has a knob for your throttle curves when in idle up mode. So if you dont plan on adjusting throttle with the knob while flying inverted etc then just stay with the CP TX like I did.

Search for Horizon Hobby. That ll give you the home page. Then look for Blade helis and hop ups for Pro

can i use the ultrafly outrunnerbrushless se with speedo?

I cant see why not. As long as it has enough power for the heli then it should be no problem. I really dont know much about matching motors to aircraft so I cant answer properly.
I converted my CP to the Pro but I just went with the recommended setup from Horizon. Motor is 370 brushless with the 20 amp esc
