Hellow Andrew, thank you for the info!

I fitted the Q80 in my Visa, fixed on the front without rear mounting. Previously, waiting for the Hacker, I used a Duslaky 6360T12 fitted on the same way.
The total number of fligths of the airplane is 160 flights without problems at all, all of them flying the P11 schedule. I think this way of mounting is lighter than the one with the rear mount. Can send you photos if you like.
Regarding your information, I´m using for the Q80 an APC 21x14 prop. Current is the same as you reported (82 Amps).
What I would like to know is if you tested another props, also if you have a recommendation about.

Gustavo
