Default Flying with retracted antenna ETOC

It was interesting to see QuiQue flying with almost fully retracted antenna at ETOC. I guess he can afford the damage to his sponsored radio. Or am I missing something here ?

Probably a loaded antenna

Default RE: Flying with retracted antenna ETOC

A couple of years ago, I made a full flight with my old T6XA with the antenna fully closed and did not experienced any interference or loss of signal. I noticed it was fully closed when it was time to actually close it after the flight. It was a normal flight with normal air distances and nothing special happened.

The plane was a GP Extra 300S 40 with all Futaba standard gear.

Hi guys, my question was in relation to damaging the RF output circuit, not the reduction in transmission range

Operating with a collapsed antenna will certainly cause excessive heat to build up in the output transistor. The damage may not be catostrophic but certainly does it no good and will definately accelerate the failure rate. Its kind of like driving your car with the brake on, it will go but cause problems sooner or later.

Remeber these were only 2-3 minute timed (forget exactly) flights, and with the antenna pulled out 1 section it wouldnt be any different than doing a 2 minute range check. Your not gonna hurt it in that amount of time

I noticed that when he was flying but I have flown micro helis in the ware house that way. So far so good.

????? Do you fully extend the antenna when you are setting up a plane on the bench ???? I have been flying indoors for awhile and always fly with only the first section pulled out. These are not real power houses on the transmitting so I would think heat build up would not be of the slightest concern.
