Motor, controller and batteries are now bought.

The point that made it easier to choose was that I got a nice deal on a second-hand (but not used) Actro 40-5 and Actronic 70-32 controller (also new in box). I have also ordered two 5s2p TP4000 Pro Lite batteries that I'll connect in series. I have seen mentioned in other threads that this will give about 2,1kW with an 20x10 prop. I have also seen that the APC-e may not be strong enough for this setup and that carbon-prop is recommended. Any comment on this?

Where is carbon-propellers of this size (19-20inch) available at reasonable prices?

I guess I should prop a bit "low" on the first runs to help break in the pack and to make sure I don't overload anthing. Any suggestions on good propeller for low to medium power?

So what do you guys think? Is it a good setup?

BTW: The controller do not have lipo-LVC. Is there a device that can be connected between the controller and throttle-channel to act as LVC? I also need a sort of BEC-circuit. What is recommended?
