If you have a smart phone, check for an app which has a level bar. I use Carpenter on my IP5.
Here is a picture checking thrust angle after a major mod on the motor box of my Extra 330SC. First I place the phone on a surface of the plane which I know is at zero degrees of incidence in relation to the wings then I reset to zero degrees. Now I can transfer the phone to the motor and check thrust angle.
The same method can be used for throw gauges, just align the counterbalance and set elevator to zero. Now move to full deflection and check your max throws.
These devices are incredibly precise and easy to use and believe it or not you can even make/ receive calls.

Here I'm checking the downthrust angle of my Corvus 30cc after making a plywood motor box. The first step is to "zero" the level at a surface which you know is 0deg in relation to the wing. -

Now I transfer the phone to the motor and check. In this case I have 0.7deg up thrust which needs to be corrected by adding washers. -

Now the same check performed on my Skyline Extra 330SC 60". Thrust angle check=0 degrees which is just what you want for a 3D bird. -

Here checking the aileron throws. First "zero" the level bar on the neutral position. -

Now move the control surface to full deflection and check the angle. You can do the same for low/ medium rates if you want.
Build (assembly) log of one of my first 3D birds. Really nice and affordable plane to learn 3D on. Most of my building techniques are described there (use at your discretion 
).

If you buy top quality motors you'll probably never need this but If you are a cheap bastard like me this may help.
Seriously, I could buy top quality motors but I simply enjoy tinkering with my gear as I feel I get a much better understanding of how things work and I feel I'm much more prepared to do any troubleshooting or repairs if needed.
This is a step by step procedure on removing magnets, cleaning and re-glueing them with a mixture of thin CA + baking soda.

This may help you with your first rewind if you're crazy enough to try.
Warning: rewinding motors is extremely addictive and up to this date there is no known cure for it.
