Okelly is right - JR821 servos are currently the best value for money IMHO.
I have them in my Zen 90 running on 6.0 volts and at 0.15s they are fast enough for me (flying expert class F3A), not to mention the 88 oz. of torque.
But a lot of servos today can do that.
What distinguishes these low cost digitals from the rest is the gear train's quality!
The composite gear train shows no backlash or "play", not even after dozens of flights.
None of the servos I own (I also use Futaba and Hitec digitals) can pass that test!
One remark though - at more than 40 grams they are a bit heavy and I would rather use something lighter for a 70 size F3A model.
I have Hitec 5245MG which are excellent servos and weigh only 32 grams however with their metal gears they do start to develop "play" in their gear train.
As a general recommendation stick to nylon/composite gears in pattern models.
As for the order of importance regarding servo application, I do not have anything to add...
Finally, I would like to wish you good luck with your Zeque, it's one of the nicest pattern planes today - I wish we could have them in 110 size!

Cheers,
