You also need to give us the distance between the pushrod and the center of the servo, like...how far out on the servo arm the pushrod is.
I think that the servo should be able to lift 1.45 lbs with your setup.
"Link connection at horn is 30 mm (1.2 in)."
"For the record, I was able to lift a 1 gallon container of water after installing a seperate home made BEC. 1 gal is 8.34 lbs. "
Bit the big dollar bullet and placed an order last night...

So, although my fortay is electronics, I believe I have exhausted the simple Voltage reg's short of breaking out printed circuit board and making something messy, I went with an ESC that could provide 6 Volts to get to the higher torque range of any servo (along with 5Amp capability to drive it) then topped it off with a double-the-torque-mack-daddy robot servo. The airtronics will work nicely for steering, so no waste there.
The ESC also offers a "bit" more options than my $30 test esc where motor options are concerned. (This 3 speed tranny is gonna ROCK!!)
Thanks Victor for your input. Those calculations reminded me why I went to school for electronics and not ME. LOL
