RE: DX-7 related crash?
G'day Mate,
Was your Katana, the CMPro 140 size?
I have one ready to put together, this will be my third, I love em, & will be using my DX7 radio in it, it will have an OS 160FX for power, & I will be using a 1700Mah nicad pack, with 1 digital servo on the rudder & JR 539's on the other controls, I have used this setup on a Giles 202, same motor, same servos & I had no power problems, using 1 large battery pack.
But I would use the battery port for one pack & a spare socket for the other, no Y leads.
Just my way of doing things.
PS. How old was the switch/switches that you were using?
They have been known to fail under load, & then test fine after, the best way to test a switch is to use a low ohm meter, & check the resistance accross the contacts of the switch, it should be less than 0.5 of an Ohm.
Or test the voltage drop across the switch, there should not be any voltage drop.
