ladies and gents check this out.

a friend of mine tested a 4525 limited edition in a faifa 90

he only had a jive 80hv but it just about worked do the cold wether in sweden

he said it was like flying a overpowered logo600 but in a bigger package


he will come with proper reading when he get his jive 120hv so he can push it to the limit and hope for warmer wether so batteries warm up so they deliver proper c rating

no there is normally no problem for a esc to give power to motor,it is when u come out of something and it will over rev a bit
difference between castle and kontronik is not only the price like some people like to think

when i talked to fredrik this flight is a normal flight like he always fly and hold rpm 25% better then with a pyro
cost of flight time for sure, nothing is for free but not as bad as u think if u not abuse .

if extream pitch pumping it will take some serious amps

Iam reading decent reviews about the Align MX series as well. Especially for the 500 size, the specs look too good.
