i have a blade cx an i have only had it for 2 weeks and it seems like i don't have the power i used to. It takes 3/4 throttle to get in the air and it barely climbs. i have two batteries and they act the same way. I have been really careful about not over discharging them, I've never had to charge them for more than one and a half hours so im pretty sure thats not the problem. Could it be the motors? i have had several blade strikes, if that can cause the motors to wear down. I have also shortened the flybar. Remember that this is only a two week old machine and i already have a drastic loss in power. If anyone has had this experience or knows what is wrong with it please help.

yeah, it could be the motors. Did you by chance break them in? That could help, also if you have run several packs through them a day, that could be wearing on it as well

About the batteries, do you have a volt meter? If so charge the packs and get a voltage reading off of them. If it's 8.4 you're golden, if it's below 8.3, then your charger or battery has a problem.

also look at this page under the cx2 section

How do i go about doing this? i don't have a volt meter. Im looking at over 50$ to try these suggestions, is there a way i could isolate the problem? Also how do you break motors in?

here is a volt meter for $3 bucks

hopefully that should help you out a bit

dude at microcenter i got this tricked out one for 6 bucks! (LED, all that good stuff) and another classic but accurate one for 12 bucks! Its helped me before in my RC heli career!

and take the dude above me's advice. Hes legit, he had some good scources for fixing my origional CX

Yeah i bought the one from harbor freight and it works great! for $4 lol anyways my first batterry came out to 7.7v and the other 7.8 so they are way under power, thanks a bunch! both of you. So now its either the batteries or the charger.

might be some relevant info here....

if you end up needing a new charger, this one isn't a bad choice, it's a little better than the eflite charger and it's only 16 bucks with shipping.
