Hi all,
noob be nice :) and this is about a cheap nasty IR micro heli however I think the as far as learning goes the fundamentals are similar.
the story:
Picked up this 4ch heli for next to nothign, thought worse case, lots of bits.
Got it home and it actually flew reasonably well. It was my first 4ch and isnt sideways flying the coolest thing!!
Anyway unbeknown to us the charger is opposite polarity to the others we have and we cooked the battery. Never even considered they were not standard. Lesson learnt.
LHS had some old batteries (different kettle) so I grabbed one and went about replacing it.
No major dramas ( I am an electronics tech) Powered it up and all controls seem to function.
However it flies like a scared cat. All over the place like it has a mind of its own.
On take off it seems to want to go backwards. So a little adjustment on the control is in order. I can kinda get it to hover but then it will just start to swoop sideways and just doing things way outa control.
I dont believe its a signal problem.
Im more suspect that the battery was slightly bigger/heavier. Original was a 100ma the new one is 150ma and was a tight squeeze. Possible its COG is upset. Being new to it all im not sure how much diff this would create. I can only judge it on what it flew like first time and Im pretty sure it was not that crazy.
any thoughts?
BTW no tail rotor and has Gyro and yes im searching web for them now.
Measured the battery packs. ( I measure things in grains Im an archer :)
Original is 46grn. 5.2x14x21mm
new is 65grn 7.4x16x23mm
Which ,leads me to believe the COG would be out and possibly causeing the problem
