Performance demo - Eflite UMX Carbon Cub with a 5030 prop
I switched to the 5030 prop after flying with the floats to get a baseline on water & land. Here's some non-scale flying, to demonstrate the low-end grunt of the 5030 prop.
First flight with the 5030 prop. To say that climb-rate is much improved would be an understatement. Thrust-to-weight is just over 1:1.
Here's another clip. I condensed it down to mainly power-climbs, 'power-loops', torque-rolls, hanging on the prop - and a few touch & goes.
