The B29i UAV Engine System is the debut offering in the Power4Flight family of EFI powertrain solutions. This engine combines high power-to-weight with low acoustic signature in a simple yet reliable propulsion module that fits a 3W-28i footprint.
The B32i is a conversion based on the Zenoah G320 engine. It has integrated shaft driven forced air cooling and a 2kW generator making it ideal for use on hovering platforms. The B32i is targeted toward hybrid electric propulsion applications.
The B35i is our latest EFI conversion based on the DA35 engine core. It has an impressive power to weight ratio and the ability to swing a wide range of props.
The B50i UAV Engine is the newest two stroke engine system co-developed by Currawong and Power4Flight, beginning production in June 2016.
The A33i UAV Engine System is an aerospace grade form-fit-function upgrade for the B29i. Rather than being adapted from commercial engine offerings the A33 is designed from the ground up by Cobra Aero to meet the demanding requirements of UAV applications.
