Good stuff, confirms my suspicions, thanks! Now, if only someone had some thrust numbers...
Regarding the thrust, 3.5-4kilos with decent 8S set up will be good enough to zoom around your model at 5 kilos, AUW. With the cheap china set ups it will struggle.
If you keep it simple, very light, as bungee launcher, no landing gear you might get away with decent 6S power around 2.5-3.5 kilos thrust.
This are just some rough figures based on my experience.
