Jos tuntuu että 4525 tai 4535 mottin tehoreservit on aivan liian alimitoitetut, niin tästä saattaa löytyä apua ongelmaan

no mikä onneton kikkare toi nyt muka on?
tällanen se pitää olla! ;D

on vielä "in stock" ;D ton kokoseen runkoon sais varmaan hyvin tehoakin ku käämis ite ;D

The stock 4035 seems a rather sensible choice, IMO. It's 300g lighter, considerably cheaper (USD 600?! For a scorpion product? You're kiddin'...) and has plenty of power in my X7 (long-shaft version).
Yes, it's not an absurd-super-hero-power setup, but it leaves the 700 nitro in the dust and is already mildly scary to fly with a small pinion. You know, this weird feeling when you expect the heli at a certain spot, find it somewhere else and wonder how it got there.

IMO if you are satisfied with that kind of power, nothing beats Align 700MX (530kv) i have logged 7.5kw spikes from it and little less from 510kv version! those are cheap motors also.

Yes, but electrical peak power tells little about actual mechanical power, once the iron saturates (http://en.wikipedia.org/wiki/Saturation_%28magnetic%29).
The current goes up but the efficiency goes down at the same time, puffing the LiPO and turning the motor into a resistive heater that warms nicely in addition to the burning ESC :)
Extreme current spikes in an otherwise balanced setup are what I'd expect from a bad motor = LiPo-killer.
-
thats true. but when that happens the motor goes hot. these motors run quite cool. :)
people have wounded these to even bigger powers and there seem to be no problem.
these are actually quite big motors. i have 1 of these opened in my table and stator diameters are 4235...
