Can I use the 2-in-1 with a heading lock gyro on my BCP.
I don't see any way to turn down the mixing as with the 3-in-1.

correct, the 2n1 includes revo mixing so it cannot be used with HH gyros. if you have a 3n1 (or a 4n1), you can use that instead. if not, all you need is a pair of brushed esc's, like 2 pixie 10's or something. 2 small brushed esc's is more durable, cheaper, & lighter than a 3n1 anyways.

since you're in the process of upgrading, now would be a good time to consider upgrading to a brushless main. you could put the $$ for the brushed main esc towards a brushless main & esc instead. not trying to upsell you here, just wanted to make sure you to consider all your options.

Yes, I'm setting up with the brushless main. I have a spare 5400kv brushless installed. Just bought the G90 gyro.
I'm going to use the pixie esc for the tail which I've converted to direct drive.. Once I get things functioning I'll
go to the Bell mixing setup on the head...

sounds like you're on your way to a very nice setup. 5400kV is on the high side, so you'll definately want a small pinion. i believe 8T is the smallest you can get for the larger brushless shafts.

cheers (i'm late to work now)
