CONVERTING THE GIANT U CAN DO TO ELECTRIC
Story by Joe Hass of the Skymaster R/C Club in Detroit, MI:
One of the easiest electric conversions I ever performed was the Giant U Can Do. The pictures really tell the story.
To hold the motor in place an aluminum bracket was fabricated per the drawing that comes with the AXI motor. That was the hardest part. The bracket was then attached to the firewall with ¼-20 hex head bolts and nylon spacers. The electronic speed control was easily mounted to the area that is usually occupied by the muffler. This kept both the motor and speed control in cooling air. An external arming connector was created with Sermos connectors and mounted so that it is easily accessible from the bottom of the fuselage.
The tray for the battery was created from 1/8th inch aircraft plywood. It slides into a slot created on the backside of the firewall and is held in place by 2 screws in the back. Only the top of one fuselage former needed to be removed to allow installation and removal of the battery. The battery is held in place with hook and loop fasteners on the tray and the bottom of the battery. A hook and loop strap is added around the battery for complete security. The original hole for the tank allows enough air to flow through the fuselage to cool the battery. An air exit hole was cut into the covering on the bottom of the fuselage.
The final configuration utilized an 22 X 10 APC electric prop, an AXI 5330-24, a JETI 90 ESC and a 10 cell 5000MAH Li PO.
Flight performance is excellent. Take off is at less than ½ throttle. Vertical almost goes on forever. It will easily hover. Knife edge is effortless. This is one big airplane. While you can use a 4 channel radio you can have a lot of fun mixing the ailerons, flaps and elevators for phenomenal square loops, spoilers and more.
