first pattern plane?

i have flown 3d freestyle and some pattern but that was on a friends aircraft that he lent me..... Now its time i had one of my own so i was thinking of making somthing loosly based on the murcury.
My main question is how to mount the servos
here are some specs:

Controll: throttle, aileron, elevator(so not true 3d/pattern)
Reciever: 3.05 g
Servo x2: 2.85 g each(manufacturer is dumb because he uses metal case for servo! could save at least .6 - 0.7 g!!!!!)
Speed controller:1.9 g
Motor: (undecided)
Battery:1cell lipo(undecided what Mah)
Wingspan:16 inches

so it will be micro and mainly for indoor use
I probably sound like one of those guys who is paranoid that his model will be too heavy but weight is very critical at this size.
My main problem is how to mount the servo's

happy flying

I used 2-side tape, but nowdays I'm simply glueing it. I'd glue them directly onto depron. According to me is it the best way.

num,

The servo mounting question has been addressed in this thread. I think you will find some helpful ideas on mounting servos.

I agree. I had been using double sided tape. It works okay at first but I found that after a while the servo can shift slightly, changing control trim or even fall off altogether. I'd suggest wrapping the servo in a strip of masking tape and then mounting it with a very small amount of epoxy. That's what I've done the last couple of times and it seems to work very well. The masking tape is intended to allow you to remove the servo without having it covered in epoxy - that's the plan but I haven't removed one yet since I've only been doing this a while!

Num,
just noticed your 16" wingspan. Most F3P indoor planes havd 32" wingspan, and weigh about 145g.

Not sure the dimensions you have described will work well for F3P. I would recommend a Clik!, Manta, Mercury, Nexus, or Vrolet, build the kit, and you will get lots of good ideas on how they recommend mounting components.
