RE: bladecx2.com
After all i've read about them, i don't recommend to order from them.
They seem to just rebrand/repackage Dynam Vortex (and other) parts, and put a (much!) higher pricetag on them.
When i just got my CX2, i've ordered with them before doin' research...
Luckily i was on time cancelling my order, because it seems they aren't... well... how to put nicely... a 'correct' company.
After placing my order (and started the money transfer through paypal), i've tried to get in touch with them several times, without results.
No replies on emails, didn't pick up the phone, etc.
Further more, they (or he) claim(s) that plastics are much better than alloy because it gives less friction...
I've realised in time science class really told me otherwise (why wouldn't engines in general be plastics?).
And i'm not sure if alloy's are that much heavier than the plastics, but i haven't measured (scale not accurate enough) yet.
The heli can handle a (little!) bit of extra weight, just be sure that it isn't stressing weaker parts due to imbalance and vibrations.
Their motors are just stock ones with a hole in them and some say they even perform WORSE than stock ones.
The shafts are just Dynam (or Graupner or Esky), the grips as well and the 'high quality plastic' is the same as stock plastic.
You can get all the stuff sold there on other, legit, places, probably cheaper as well!
