If the brison is anything like my FPE 5.8, its smooth as silk.
In fact I think my FPE vibrates less than a ZDZ (not doggin ZDZ I think its a great motor as well)

My FPE is a STRONG pulling motor, and works fine I believe even in a 35% plane.
In fact I have one mounted in my JTEC PANZEL that will fly in the next week or so.

Brison and FPE 5.8's I think are a great motor for the money.

So for the giles, just make sure the weight isn't an issue, but vibration shouldn't be.

my 2 cents!
