RE: King Kobra build by TWN
The 475 is plenty of servo, don't forget when the king kobra came out very few servos had the torque and speed of the 475. As for the lading gear blocks getting loose? I have flown my king for sometime on rough field and they are still tight. The only change I made was for the aileron set up. Insted of using one servo. I went with 2 HS 225MG side by side in the same location, this way I could run flaperons.
Look in my profile for my King Kobra.
