Hi Bruce,

Thank you. You just validated my decision. I bought a Hitec flight pack with 4 Hitech 645's and a 6V 1400 Ma battery about $207 total from Servo City.

There has been so much discussion on this thread regarding servos I finally called Sig. Their radio tech said they used the 645's. I was going to go with Hitec 605 which are still available here and there, but he placed a high value on metal gears. Yes, I know the 645's are a few nanoseconds slower than other servos. But, I'm sure they will get the thing off the ground.

My Mayhem finally made it here. Nifty looking, but I doubt it will fly straight with the amount of right thrust built into the firewall!

Hope this helps with others in the servo quandary.

Gotta get the glue out. -- Robin
