A short story first.
Some months ago I purchased a clone 450 V2 and destroyed it 10 minutes after the first battery charge . I was attempting a blade track when the verandah furniture jumped all over my heli at full throttle due to a brain fade. I was left with a main frame, motor, ESC, UBEC (or is that an SBEC), battery, 1 servo and some velcro tape.
I have spent many hours hunting down and reading info, plus chasing bits to rebuild. Rather than buying a new one I now have a heli that I know inside out and back to front (mechanically) and it spins up smoothly.
I am now following Radds School of Rotary Flight (no more mucking around).
I am only running one 11.1v 2200mah 20C which I allow to cool before and after each charge (2 new ones on the way from HK to satisfy my hunger and keep Radd off my back(hahaha)).
On the 3rd charge following a series of 7-8 minutes at 50% throttle with 5 degree pitch I suddenly only get 3-4minutes at the same settings, if I have zero throttle from 10-60secs I can get what appears to be another minute at 50%. The ESC and SBEC(??) are hot to touch and battery cables are warm. I should mention here the motor is KV3680.
Back to the internet for more info (I drown when it comes to electronics).
The original ESC has no markings at all so I went searching for a replacement thinking mine was dodgy and this is where to start, however looking at the variety available I have become totally lost.
Now back to the subject title.
I would appreciate a steer in the right direction, should the ESC be 30, 40, or 60amps?? will a plug and play suffice or do I get one with a programming card, should it have a 2,3,4,5amp BEC or should it be a stand alone.
Any info greatly appreciated.
This unit was orignally purchased as a prelude to bigger and better things however once I have mastered a hover and a simple circuit I will hang it up, buy an AXN and move to Tokoroa those guys know how to have fun.
