Less distance because of cold temps, or...?

[Monkeyleg]

I have an itElite dbs Phantom antenna. Months ago I was able to fly my P2V+ out to 12,000 feet at an altitude of 400 feet over farm fields. Today I did the same route at the same altitude, but only got 8200 feet.

The temps the first time were in the 80's. Today was about 50. I crashed the first P2V+, but I'm still using the same controller and antenna. Would temperature affect distance, or would it be the Wifi transmitter in the new bird?

Thanks for any replies

... would it be the Wifi transmitter in the new bird?

Most likely the wifi module inside the new bird.

I swapped out the internal stock wifi antenna patches with an external dipole antenna mod kit. I estimate an extra 25% to 33% distance increase by simply upgrading the bird side wifi antennas.

NOTE: The distance increase was compared and measured doing Ground Level flight (10 feet or lower at the furthest distance). So, perhaps your distance increase would be different doing the 200 foot high altitude flights.

The temperature should have no direct influence on the propagation especially since we're in the 2.4 GHz and 5.8GHz bands. It does sound internal.
