I am considering one of these for a surface runner Revell U-boat, if it will work in a boat I presume it wont have issues with the rx being close to the water (have read that the 2.4g wont work IN water but hope that it has no issues just above the surface) otherwise maybe the rx can live in the 'tower???

No probs at all.

This is one of three of my FSR-V boats, running a Spektrum DX5e, with a 10cc engine, at speeds in excess of 40mph. Rx is probably parlty submerged in the radio box, just behind the propellor. Bear in mind this is a sealed box, and half the long aerial and all of the short one are inside the box.

Hi there, I'm no expert, far from it, but from what little understanding I have about the DX5e, it works perfectly above the water, it's only when you want to run under the water that it won't work. Summary: No good for using in working submarines, but surface running ones should be fine!?

To the top of the class with you!

Should be fine Zed.   As has been said 2.4GHz is a non-starter for diving subs but that's he only real limitation.   BTW to be pedantic and in this case it is significant, the only part of the "long aerial" which actually acts as an aerial is the thin bit at the end (approx the same length as the short aerial).   The rest is simply subminiature coax feeder.   In your case it will certainly help if you can either mount the whole RX or at least the active part of the long aerial up in the conning tower.

Didn't know that, they say you learn something new everyday...

Thanks

I'm still learning and I'm ancient!   If you look carefully you'll notice that the end inch or so is thinner and if you look even more carefully you'll see that it's the inner of the coax where the outer sheath has been stripped off.

well, thanks for that gents

got a bit of building before I get radio equipment yet but aslong as the prices dont go stupid then 2.4 is the way I will go

where is best price and place to buy (always willing to pay a little more for good honest service)

where to avoid!

Guy, as my father said recently in his 90th birthday speech the problem with been ancient is that you can still learn something new every day, trouble is it is probably the same thing you learnt yesterday and then promptly forgot! Something to look forward to! Ian.

Not sure about the best price, but Micron Radio Control certainly give good service, and they are not the most expensive. Just bought a DX6i and AR500 from them, have had other items in the past.

Thanks Ian!    I think I'm already at that stage.  OTOH my father (93) forgets after 10 minutes rather than  a day 

BTW are you on North  Island or South?   My daughter is in Mapua, South Island and my partner and I have fallen in love with the country since visiting a couple of times.

Just another quick update...

I have fitted the bits to my TX now so both sticks are self centring and was really easy to do and took about 10 minutes from start to finish. I do have one last silly question to ask though, which is more of a double check really but:

When plugging in servos/ESC to the receiver, under the 'bind' label it has it marked the the negative should be on the outside of the receiver? Also, it has the different channels marked with different aircraft terms, but conveniently one is labelled 'rudder'. Is this where I will plug in my rudder servo?

I am happy to post a picture if it will help..

[wideawake]

Hi there

Yes servos should be plugged into the receiver with the black (-ve) lead to the edge of thee RX.  If you look you'll see +, square wave (data) and - symbols at one end of the connector header.   

Yes, the logical place to plug your rudder servo would be to the "rudder" connector which should be on the opposite stick to the throttle.   One other thing, if you want the throttle failsafe to work you obviously need to use the "throttle" channel for the ESC.   Further thoughts on this and the hidden mode swap switch in my MB article.

Cheers wideawake, I'll fish out the issue of Model Boats and have a look!

OK first of all how much for the parts to change to ratchet on both levers? and secondly, made the mistake of going to a choppy tidal mill pond at Stoke Gariel and then remembered to clean my boat out prior to the Open day at Exeter this past Sunday. No real big worries after initial shock of brine water left unattended, corroded grub screw on prop shaft, but still turns freely, problem was, set all up again after major wash out with fresh water and sailing fine for 15-20 minutes and lost control, plowed right into the dock, luckily right at my feet, I picked it up and shurt all down. then back on its stand did a reflash and all seemed well, I thought it could be interference, but the TX/RX are uniquely bound , so gave it another go and  after 20 minutes, same problem, Any thoughts?
Using Action ESC and BEC with 7.2 volt power supply.

I wasn't charged for my parts to change it over.
