Stock motor I assume?

I haven't tried it yet but I will be sure to put my detrum 40a in there when I do.

I'm thinking 4s will add just enough kick the 9x7 3 bladed prop.

I use an orange GWS HD 1080 with a Plush 40 A controller in my 4s setup. I had bad experience with the stock prop on 4s : it lost one blade during the flight. This cheap plastic part is more for decoration. If you fly with 4s, you need for normal cruising not more than half throttle - but for loops and barrel-rolls ( please only to left) the extra motor power is awesome! If once you tried the 4s, you´ll never go back to 3s.

I'm about to buy this gyrocopter and want to make the battery out of 1S round 1200 mAh cells. I read it needs the 3S balance connector for the rotor-engine.

If I make a 4S battery I can attach 2 balance-plugs. A 3S for the rotor-engine and the 4S for charging and the voltage sensor (telemetry).
A pack made of these cells is probably lighter than a normal battery,


I can't order that propellore from the HK European store.
I can't even buy that size.
What are the dimensions of the original?

You also replaced the ESC. I think I have a 40A plush somewhere.
Probably wise to put that in immediately

Should I do a conversion immediately or is it fun to fly it with 3S to start with?

Here's how I balance blades:
1. Weigh each blade to the nearest 0.1 g. I use a surplus triple-beam balance, although a cheap postal scale will work.
2. Find the CG of each blade, measured either from the hub or the tip
3. Add weight to the underside of each blade at the CG so all the blades weigh the same.
