Hey higher C rating the better, you will have no issues.

Buy as much "C" rating you can afford is one school of thought but to buy a 60C 5000 mah 6S pack for this plane is overkill. 30C is sufficient plus it is lighter and less expensive.

I'm trying to find a 6S pack that I can use in two very different planes. One is an EDF and the other this plane. Just trying to save money and time with charging.
I don't plan to attempt any 3D stuff with the CZC. I plan to just fly it around as a cub and also do some towing service for some glider guys. So I won't be pushing it hard like hovering and such things.
To answer your question..
no, there is no issue using better high C rated packs
your voltage sag will be much less during flight and have less ripple current through the electronics

the motor will only pull what it needs to fly

I think the packs I run are 65c 5000. Had the packs for a heli, and wanting a plane that would use the same packs is why I got the carbon cub.

No problems at all.

EFLM4060A
Kv: 400 (rpms per volt)

Io: 2.7A @ 10V (no load current)


Ri: .06 ohms (resistance)


Continuous Current: 55A*


Max Burst Current: 65A*


Watts: up to 1700


Cells: 16-24 Ni-MH/Ni-Cd or 5-7S Li-Po


Recommended Props: 14x8 to 16x10


Brushless ESC: 80-Amp (EFLA1080B)


* Maximum Operating Temperature: 220 degrees Fahrenheit

* Adequate cooling is required for all motor operation at maximum current levels.


* Maximum Burst Current duration is 30 seconds. Adequate time between maximum burst intervals is required.


A 16-8 Xoar appears to be the ticket from my first couple flights.

Well that sounds like a winner. It all depends on how you want to fly the plane. A 17 x 6 would give you a ton of thrust and that extra inch of prop provides more airflow over the control surfaces.

If you like it as is, congratulate yourself.

If I can find a 17-6 in a good quality prop I'm going to give it a try.

good thing I wasn't airborne

The weather warmed up so Ithought I would charge a battery and taxi around in my yard, first on wheels then tried my skis. My prop decided to fly on it's own leaving my CZC sitting there. guess I didn't torque it enough. or maybe it seemed to me the adapter step was bottoming so not putting enough clamp. I bought the Eflite aluminum spinner and adapter using the stock prop. I reamed the prop a little deeper so I think it is good now. Taxied around on skis after that , all seemed balanced but I need to tweek my homemade articulated landing gear , would over extend when I hit deeper snow or rough patch. have to come up with a better way of limiting travel. If I get it working I,ll post pics but or now I need to do some more designing. Still haven,t maidened it as every time it gets relatively warm it's windy. Chinnook we call it. Flying it on Pheonix , if it flys that easy IRL I'll be able to handle it no prob. (famous last words)
