Weston Magnum build issues
Kevin,
It may be hard to seal the gaps with this new "non-stick" covering on the Magnum. I've seen hinge gap tape for sale, I don't remember where. I generally use clear monokote on ARF's.
The CA hinges seem to work good enough if the slot is tight. On many ARF's the slots are cut too wide. In this case a good epoxy hinge should be fine. Either way, you should have ZERO slop. Use servos that match the performance you plan to get. Some of the racing guys even put a piece of tap accross the aileron to wing tip joint to make everything even tighter.
Also remember the faster you go the less you need to deflect the surfaces. Use Expo or your rate switches. If you use the rate switches just remember to go back to a higher rate when you slow down (ask me how I know).
