Can you use high altitude propeller for flights of 400 or so?  I got a message telling me that I2 knew what kind of propeller was installed and not to use low altitude?  Not sure why they would not work, they look the same.

Hi R,

When you say "400", do you mean feet, metres, flight level, AGL, ASL? Even if you are talking metres ASL, you would not need special props. DJI sell High altitude props for the I2 which are good for 2,500-5,000m so I'm pretty sure your machine won't mind being fitted with them. They can be found here.

i have a couple pair that i really bought by mistake, i just did not know if i could use them for everyday use at 400 feet or so.

Sorry R, I misread your original post. I would imagine you can use them but the performance won't be a good. Not sure if you'd notice the difference.

Roffen, we don't suggest to use Quick Release Propellers in low-Altitude location.
These propellers are designed for high-altitude because they have strong propulsion against thin air. But they won't perform very well in low-Altitude.
Please use the normal Quick Release Propellers for safety.

Safety is NOT the issue, its a matter of efficiency.

The high altitude props have a higher pitch and will turn slower at low altitudes, You only need the HA props at above 2500m.

I've actually flown from 2700m (conservatively) at the flight went well. The motors turn at a higher RPM because the air is thinner. GO 4 WILL tell you to use the HA props above 2500m but not above 2000m.

Hi Mindy

Can you point me in the direction of some low altitude propellors that i can purchase as i had the high altitude propellor warning today too?

Thanks

Hi Adam, we do not have the low altitude propellers, when flying in the altitude lower than 2500m, please mount the included Quick Release Propellers.
