Would it be better if the antenna was 6".?

That's all they are long. They aren't like the regular 18" antennas.

I thought they were 3"
I would think if they made them normal length like 18" they would stop roaming.

I don't know what to say. I haven't had any problems out of mine.

3pm 2.4
 

I recieved my 3pm from Tower. My coax is about 3" long with the coax bare at the end no probs with recep. Awesome radio with no need for sep. fail safe.
Very easy to program and more than enough features for club racing. I give it a A++++++++++++. Futaba did it again for the guy with the budget. Thanks Futaba!!!!

quick question for the radio guys. now that radios are coming with a fail safe do people still need to use a regular fail safe? is there a problem if running both so there's always a back up?

I love my 2PM, it is as responsive as I could hope. Wish it would have come on HRS mode though, think I had it for 4 months before I realized I wasn't getting anything better out of my digital servo's.

Have any of you guy's used a booster yet? You can get " pen style" 1/2 watt 2.4ghz boosters for your wireless internet antenna and run it on your transmitter, it uses 12 volts so you can power it with your transmitter batts ;)

I also have redundant failsafes on my car and have had no issues.

I went through my first set of Alkaline AA batteries in my Futaba 3PM 2.4G. Time to replace those batteries after about 2 months of use. So I'm going to try some 2500 mAH NiMH AA batteries (8 required).

Whats the best way to charge these batteries with the ICE Charger?

I'm thinking charge the batteries in the transmitter's battery tray, but with the tray removed from the transmitter..the battery tray connector matches one of the adapters that came with the ICE. Is there any good reason why I shoudn't charge these at 1C rate? Or is it better to charge these at C/5 or even lower (C/10, C/20)?

I just purchased the Futaba 3PM 2.4Ghz and installed the rx in an E-Maxx 3905. The antennae is really short and only goes up the tube about 1 or 1 1/2 inches (doesn't get past the top of the motors). I know that 2.4 Ghz will be a much stronger signal, but that makes me worry and I didn't know if anyone else had any experience with that or any ideas. I am worried about it shooting off like a rocket and the failsafe is confusing so I am not sure I have it set up correctly.

Also, I used the Y adapter for the servos, but had to reverse the steering and throttle on the Transmitter. Did I hook it up backwards or is that the norm?

Interesting that some people are reporting 3 inch antennas others are reporting 6 inch. My reciever antenna is about 6-7 inches long. I originally had it coming out the shell of the car, but when my car came back off the track after a race with the top half of the antenna tube gone (fortunately the antenna wire appeared to be all there) I decided to keep the antenna all under the shell. See pictures below. The antenna wire extends through the entire tube except for about the last 1/4 inch or so.

Plenty of people claim to have 6 inches when they only have about 3. Totally normal. LOL

Looking to pick one of these up how big is the receiver ? im running xray m18
so need a small rx

Cheers

RE....2.4fasst
 

Will the 2.4 fasst system work on my 3PJ, I would prefer to buy the module and receiver and use it in my 3PJ, but I don't know if it is compatible. I've seen a couple of Hobby shop mail order adds that that say it is. But I've been told on here that it isn't. We took the module out of my friends 3PK and it looks like it will fit the 3PJ but we didn't want to try it. I have e-mailed Futaba but haven't had a reply yet.
