Who have seen Nemesis graupner?

[19Patrick83]

I've seen micro nemesis on youtube but was the old version 450mm. Now graupner build 640mm version. Someone had seen this model. What kind of engine must use? It's possible to use a powerfull brushless with about 5000K'v?? Is overstressed?

I have seen the smaller one fly, and have had the larger one out of the box looking at it. It is all white foam. I was talking about a Super Park Jet in one, I don't know about an even higher RPM / power motor.

PM Scalefreak, he works at East R.C. that's where I was looking at the new one. He's a motor expert and should be able to help you out....

5000kv would be good. An inrunner will be your best fit inside the fuselage. Run something like a 5x5 apc thin e prop on a 3s 1200mah or so.

OK but the weight? with 3s 1200 or 1500 it's not over load?

Could you indicate some engines-esc-lipos from this site?

A Polyquest 1500mah 3s pack will work well, just keep your full throttle use to 15-20 second bursts. The prop I mentioned is what you want, but I didn't see it on the site you linked to.

Hope this helps!
