Hey guys I just moved and the wife is making me get rid of toys. so just a heads up I'm going to be posting my MCPX and spare parts for sale. The heli is complete but I have crashed it more than a few times, I also have a good selection of spare parts that comes with it.

Here is what I got.

MCPX helii (working condition,but has been crashed several times)
2 stock batteries and charger.
Used set of High performance blades


SPARE PARTS

2 sets of fast flight blades (bullets)
1 set of high performance blades
1 feathering spindle
1 carbon fiber main shaft
2 landing skid and battery mount
1 main frame

If anyone here happens to be interested PM me, I will also post a link to the ad I just have to get home and take some pictures of everything before I post it.

I bought a complete brushless combo from Flying Hobby with ESC, convertor and motor. I think the motor is something like C05M 11500kV ??

I also bought every size pinion from 7T to 11T to experiment with. I'm happy to have just a slight performance increase with the brushless to maintain longer flight times. Which pinion would you suggest?

I agree I ordered fourteen batteries for my UM J3 Cub and Night Vapor and after a few months I found that three or four were either really puffed or had leaked. None of which had be over discharged.

Have a look at the Spyder cells from Dave at progressiverc, they are a good battery and will last.

So I just tested my TA-915 heli with this battery. The battery has about 5 flights on it.

At a flat 70% throttle curve, I get about 2:20 out of it.

When I flip to IU2 which is 100% flat throttle curve, the heli falls from the sky.

Tried it 3 times. Powers down every time. This same process is not an issue with a Hyperion battery.

As I said they are hit and miss but for $1.50 i dont mind.
I get 2 minutes with them on my mini cp (normal amount of time in stunt mode with a mini cp) and have quite a few flights on them and they are still just as good or very close to as when got them. Though my motor from back to back flights is going. I have had other turnigy batteries last me hundreds of flights or just a few..but that is why they are cheap
I dont have a video of the mcpx with them but this flight (although a little mellow) is with a turnigy battery. I would think a mcpx would get almost double with this same battery.

This looks like a case of a bent feathering shaft, to confirm remove one blade put a screwdriver on the feathering shaft screw (inside the blade grip) and turn it. If the other blade moves up and down as you rotate it is a bent feathering shaft.

Looking for a little help here. Ordered a new V2 the other day.

What is the best radio set up for a JR 9303 (airplane)?

This will be my first time setting a heli up.

Thanks for the help.

Set it up as heli with 1 servo swash so you get the pitch and throttle curves. Set throttle curve to something like 0,60,90 and pitch at 45-100. St mode 1 throttle to 90 or 100 and have the pitch curve linear. Turn on throttle hold and set pitch to 50 flat that way you can easily check mid stick pitch is 0.

Also check that the main gear is seated with the flat, and that the main gear is up snug. Grab hold of the main gear and see if you can move the gear and shaft up and down, if so push it back up snug, my tool of choice is a 3/16" nut driver. Fits great over the main shaft and applies the pressure right where you need it.

if that's all tight, what else could be causing this?
I have a second MCPx and its the V2 and I get a crazy wobble that my versioin 1 never had...
