Range check question

[DucktileMedia]

I dont have my manual on hand and am curious what the reduction factor is supposed to be on most radios. maybe it varys quite a bit but a range check means nothing if you cant safely calculate the factor in which it is being decreased by. I've got a JR 9503 if that helps.

in relation to that question, when you test range with a multi you only have motors to turn on/off to check it. Using DJI, I assume there is very little danger of the craft taking off once powered up and applying throttle? It still scares me a little every time I do it and hear the motors start screaming.

Funny ive been thinkn about the same stuff with my spektrum and wookong ad-6. I always do my range check props off, as far as the reduction... No idea, ever since i crashed my F450 ive been paranoid about range on my new hexa, tslrs didnt work well with wookong so spektrum went back on, id like to know if we get say 100ft of reduced power range. Does it translate to a distance to stay within or just that u can fly a few hundred more feet lol

you shouldnt have to power the motors, as the fc sees the inputs anyway even if its unarmed. just move the controls.

It may see the inputs but we cant tell if it does.... Unless its airborne

Yeah, exactly how do you tell if you have a response without seeing something move? I suppose you could test it by switching flight modes and looking at the light.

I put a yellow antenna straw, taped to a servo horn on a servo i had from my trex 550. Plugged it into throttle then started swingin the stick. Works good becauae you can see when the signal starts to break down slightly b4 failsafe....

That's one of the advantages of the FrSky two way system. I only have to walk away in range test mode and the unit will beep once the signal starts to get low. Don't even need to move the sticks. The last range test gave me over 100 meters before I got the first beep.
