From the flight manual, gear speed is 170mph (148kts). Recommended climb speed 165mph.
ENGINE FAILURE DURING TAKE-OFF.
a. The chances of the engine failing during take-ofl can be greatly reduced and prepared for by observing the following practices:
(1) Run up engine carefully and check thoroughly before take-off.
(2) Retract the landing gear as soon as the airplane is definitely airborne.
(3) Raise the flaps as soon as the airplane reaches a safe altitude.
b. If the engine fails immediately after the take-off, act quickly as follows:
(1) Depress the nose at once so that the airspeed does not drop below stalling speed.
(2) If external fuel tanks or bombs are installed, release them immediately.
(3) Release the sliding canopy by pulling the emergency release handle on top of the longeron just to the right of the instrument panel.
IMPORTANT
When releasing the canopy, bend forward and lower head slightly so as to avoid a head injury from the loose enclosure
(4) Make sure landing gear has started to come up. There is no time to take further action, and even if it is only unlocked and on the way up, the gear will collapse on landing. Do not try to lower gear. There is less chance of personal injury if the airplane is landed with the gear up.
(5) Lower the flaps fully, if possible.
(6) Move mixture control to “IDLE CUT OFF" and turn "OFF" ignition switch. ‘ '
(7) Turn fuel shut-off valve "OFF."
(8) Turn battery-disconnect switch "OFF."
(9) Land straight ahead, only changing direction sufficiently to miss obstructions.
(10) After landing, get out of the airplane as quickly as possible and remain outside.
