Hi Fernie -
Good to hear from you. We miss you at the field !
The Hitech HS65MG servos are very good. You can save yourself the pain of stripped servo gears with those. Slightly expensive, but much better than having to change servo gears every time you crash.
For the Gyro, if your budget permits, go for a Futaba GY401 with a 9650 servo. For a cheaper option you can go with a Futaba GY201, but the 401 supports remote gain settings etc. Logictech LTG2100s are also very good gyros. For the tail servo, you can try an HS55, if the 9650 seems expensive. And if you are just hovering and doing forward flights only, you can go for a cheap Telebee gyro, as the last resort.
The stock Trex SE V2 motors and ESC are pretty good (BL35G ESC and XL motor).
