One of our 2.4Ghz receivers had it's antenna shortened after a collision at the track. It's about half it's orginal length. Will it's performance be impeded? How much would Futaba charge to fix?

I would do a distance test. Someone hold vehicle and someone holds radio. If you go a large distance(300 ft) without any problem I would not worry. Futaba would charge next to nothing to fix it.

Oops, forgot to mention that their were no issues while racing on the track though we will go to 300ft test today - thanks for the insight.

If you don't have any problems racing and you only race you should be okay. If you wanna bash with that rx i'd send it to futaba. Depending hop old it is they might do it for free, then again I have never dealt with futaba's warranty/repairs center. Are you racing the rx? or bashing it?

It's my sons 603FF that's in his Summit, he was racing but as you can imagine with little kids it's more like bashing LOL

Theoretically, it should affect it, but you might not notice it in a short range situation such as at the track. The antennas are a specific length (1/4 wavelength of the TX frequency). If it cut exactly in half, then it'd be 1/8 lambda (aka wavelength), so you might be ok, or it's close enough that performance won't be drastically hurt.

1/4 wavelenght of the TX frequency (2.4GhZ) would be less than 1cm... am I wrong???

Why is the antenna so long then?

The receiver is about 5 months old so I may try to contact futaba.

This is just me but I would replace it myself. You would need to feel comfortable with your ability to do it though. Assuming they use a standard wire, which I think they do, and not a coaxial type.

If you pop open the receiver, you'll see the antenna is just a snap on connection.

It seems to be the same connection as some of the wireless computers systems. I am going to run to an electronics store to get one close to the original length and see what happens.

I'm not sure this is a typical antenna, I have not seen it before and it looks much different from the stock AM and FM receivers... I will try to call Futaba sometime this week to see what they say....

for me it is a typical antenna as all of my cars run the R603FF, it's gray and only about 6 inches long. I think it is coaxial due to the type of plug used has a outside metal connection as well as a middle pin. FM and AM antennas are usually soldered to the board.

lmk what futaba says...thanks,

I meant the construction of the 603FF compared to the 27/ 75 mhz receiver antennas.

a 2.4ghz receiver doesn't require a long antena I only have 5"'s
That wasn't a Futaba failure therefore you have to get a new
one
