Hi folks

I've just joined the forum having recently got back into gas powered boats. So being first post attempt I'm not sure if this will show.

I am using the Spektrum DX6i transmitter with the SpektrumDSM2 (dual aircraft receiver). I have both...

Aad, I have been using the Futaba 2.4 for 2 years ands never experienced any problem behind the rescue boat or anywhere else. When I first tested it, I put the receiver aerials inside the boat ( carbon, carbonkevlar boat), put the boat in my car and shut the door and went 100 metres with the transmitter and it still was working. On my boats I use one aerial vertical out of the radio compartment about 50mm and one aerial anywhere inside ( not at 90 degrees as recommended) .

Aard,
I have just converted my Multiplex 3030 to 2.4. I tested the set up in house with the Tx set on 10 milli watts & low responce rate. I then walked out of the room down a corridor into another room & still had the servos work ok in the boat.
At the lake the boat responded well even with the Tx hidden from boat view.
I have no problems using 2.4 in any race conditions.

Regards
Grahame

Has anyone installed and used under race conditions the Multiplex 2.4 conversion on a 4000 transmitter.

Just done a 'burn-in' with the new Tx module and Rx. Fully charged the Tx battery (4350mah) and then left it on (with the display backlight switched off) to see how long it would run until the low battery buzzer kicked in (set at 7 volts). Buzzer finally sounded after 13 and a half hours! Looking at the old synth module spec sheet it drew 160ma while the 2.4 module draws less than a third of that at only 50ma. Now that I have removed the telescopic aerial and the scanner module...

I've just received my Multiplex M-link 2.4 conversion kit for my Multiplex 4000 today. The kit includes TX module/Antenna and a 7 Channel Rx, the modification itself was a quick 10 minute job and was very straight forward. I've not tried it in any models yet (still playing). If anyone is interested the fitting instructions are on http://www.multiplex-rc.de/ (go to downloads/instructions). I have been trying it out on the...

No professional services use for a long time an out-of-date principle of use of one frequency (channel). It is used only by children's toys... and... NAVIGA! 2.4 allows us to pass in professional communication at last!

I had heating problems, but when I change all servos and modify servo sistems so there was no problems with servo bruming no problems anymore. If servo is making some "brum" noice it eat alot of current instead of non, and if you have two servos making noice it causet heating problems. That was my experience with Faast reciver.

Heat issues. I had no problems with the Faast radio in the heat of Leno last year.

Heat , Questions hereby :

I've heard in the past that the Fasst receivers had issues with heat , once they got over 60+ Celsius , things got faulty . How is it now with this ? Has this been solved ? How are you doing it with this ? Any precautions ?

Would it be "useful" to have a " radiator " in the radio ? Water cooling something is no problem normally for us so that could be an option ?

Thanks already ,

Hello guys, I am usin Futaba 2,4GHz Faast. I have original small antenas and I don't put no attention about it and about instalation and it work fine and fast, like Ian wrote here. I also have carbon/kevlar boat and no problems with range, 2,4GHz range on air is about 4-6km. That is why I have antenas in my radio-box not outside and so far no problems with range around 200m that was my experience.

I agree with Dave I changed over this year and servo responce is better with the futaba Faast. Takes getting used to be able to turn on whenever I like. I have had no problems in all boats including the 26cc petrol. I am using longer antennas with both going up the same tube to above the tuned pipe. I Always one to be extra safe with radio setups.

2,4 GHz are a huge step forward... I think that in some years we will laugh at because has used retroquartz equipment!

Hi,
this is my experience:
I use system from Czech rep: www.jetimodel.cz - DUPLEX mounted in Tx Graupner MC12 (2 races + training), receivers - R8
I use two aerials horizontally, angle between aerials approximately 90° inside in radiobox, radiobox closed with acrylic glas, aerials are not outside the boat.
FSR two boat (3,5 and 15) all from carbon or carbon kevlar
Benefits:
- measure: now temperature, in future rpm and speed
- no problems witch changing...

2.4 ghz questions

feeds@yuku.com (Dave Marles) — Sat, 06 Jun 2009 23:01:10 GMT

Recently many people have been asking me about operating 2.4 ghz in my boats. I only have experience of the Futaba FAAST system which is the preferred choice of many competition fliers which should mean its OK for us.
This is my experience
I have used several transmitters 6EX, FF9, T12, FX 30, and now an older FC28 ( fitted with TM7 and TM8 module) I have used 606FS, 607FS and 617FS receivers which all use 2 short aerials. So far in 2 years of use I have not experienced a...
