Blade mCPX V1 Helicopter Review
RC Pro Review by: Tom Zadar
Transmitter Setup Guide
See my Transmitter Setup Guides for transmitter setup. The setup guides have all of the transmitter settings needed to make a model completely from scratch.
The Tx Setup Guides have different difficulty settings depending on which setup guide you choose. For Helicopters there are Standard Settings, Beginner Settings, 3D Settings. For Quads there are Standard Settings, Beginner Settings, 3D mode settings.
Each setup guide includes everything needed for setup including Model Type, Swash Type, Servo Reverse, Travel Adjustment, Gyro Gain, Throttle Curves, Throttle Hold, Pitch Curves, Pitch Curve/Throttle Hold, Subtrim, MIX, Switch Assignments, Dual Rate and Expo.
I added a bonus to every setup guide with a Dual Rate and EXPO settings guide I made for Helicopters and Quads.
I purchased the Blade mCPX BNF. When I got it I was surprised how small and light it is.
Charged up the battery and put in the settings for my DX6I. Then test hovered it.
It is very stable, smooth, and responsive to stick and throttle inputs.
Zero degrees at mid stick was dead on. No need to make any adjustments. Tracking was good.
I get intermittent shakes/vibrations at certain pitch/throttle values. This happened my very first flight new out of the box, crash free (still).
My blades are balanced perfect. Horizon told me to try different blades. If this doesn’t work I will do the canopy grommet mod.
My friend on this forum came over with his new in the box mCPX BNF. His did the same thing mine did. He did the canopy grommet mod and that fixed the intermittent shakes/vibrations.
The mCPX BNF handles wind very well! I have no problem flying in some pretty good wind, 5-13 MPH.
Will be testing Hyperion batteries for flight time, thurst, and head speed soon.
Already got the battery connectors and mount for them.
Will be adding more information to the review also.
Took some motor temps on the mCPX flying it outside
in idle up mode. These are with the stock 200 mah batteries
after a 3-4 minute flight. Outside temp was around 80*F.
- Main motor: 112.3 *F
- Tail motor: 93.9 *F
Eflight 200 mah 25C battery.
Turnigy Nano-tech 300mAh 35C.
These were taken with two different batteries fully charged
and at mid stick in stunt mode so throttle was at 100%.
Eflight 200 mah 25C battery and stock battery charger.
- 4 Minutes: 3.73V
- 4.5 Minutes: 3.69V
- 5 Minutes: 3.67V
Eflight 200 mah 25C battery and Thunder AC6 Battery Charger.
- 4 Minutes: 3.83V
- 4 Minutes: 3.83V
Turnigy Nano-tech 300mAh 35C 1S – Battery 1 tested.
225 mAh put back into the battery with the Thunder AC6 Battery Charger at .3 amps charge rate.
I did heavy throttle pumps and full positive and negative pitch pumps for minutes on the battery and still got good flight time.
- 3 Minutes: 3.81V
- 4 Minutes: 3.77V
- 5 Minutes: 3.76V
- 6 Minutes: 3.71V
Turnigy Nano-tech 300mAh 35C 1S – Battery 2 tested.
257 mAh put back into the battery with the Thunder AC6 Battery Charger at .3 amps charge rate.
- 3 Minutes: 3.9V
- 4 Minutes: 3.83V
- 5 Minutes: 3.79V
- 6 Minutes: 3.73V
- 7 Minutes: 3.7V
96.3 Grams. Full negitive pitch. Eflight 200 mah 25C battery.
95.5 Grams. Full negative pitch. Turnigy Nano-tech 300mAh 35C.
94.5 Grams. Full positive pitch. Turnigy Nano-tech 300mAh 35C.
Servo stuck on highest position or lowest position?
Mine got stuck all the way down after the bind process for some reason.
I turned the smaller white servo gear servo with my finger to get it level again.
Make sure you do this with the heli off. No power to the servo.
When you bind the servo should level itself and work fine again.
Also check the servo plug to make sure it didn’t come loose.
I had a servo go to the bottom and stay there. It turned out the orange wire at the plug had backed out just a smidge and contact was lost.
It was the rear servo which had a small amount of tension on it.
mCPX mid stick zero pitch problem, only in normal mode
This was my post:
My mCPX has zero degrees pitch at mid stick in ST-1 & ST-2.
No wind up or down on the blades.
BUT in normal mode at mid stick I have negative pitch (wind blowing up off the blades).
So what can I do to get zero degrees pitch (no wind up or down) in normal mode at mid stick?
I am using the Spektrum DX7 and using the pitch and throttle curve settings in the manual.
My mid stick normal pitch is at 50%. If I put it to 58% then there is no wind up or down.
If all three modes had wind at mid stick then I could just adjust the swash links.

“This is caused by messing up the “hover pitch” and “hover throttle” trim settings, which only apply in normal mode.
This is changed by the little rockers at the top of the DX7 – but there’s no visual indicator for it, so to find the center again, you have to listen to the beeps. There’s a special beep for center”.
Pitch Travel at 75%
Idle up mode. Measued with 0* pitch mid stick. Mid stick to full negitive pitch is 4mm of travel, Mid stick to full positive pitch is 4mm of travel.
Pitch Travel at 88%
Idle up mode. Measued with 0* pitch mid stick. Mid stick to full negitive pitch is 5mm of travel, Mid stick to full positive pitch is 5mm of travel.
My mCPX Videos
Throttle pumps to show how good the tail holds.
This is a new heli out of the box with the strong Turnigy Nano-tech 300mAh 35C Battery.
The climout is very good!
The wind was 13 MPH and 15 MPH in the first seven videos. Very windy but the mCPX handled the wind well.
