spektrum 2.4 water proofing

[ozboater]

AAs are 1.5 volts each.. 4 by 1.5 = 6 volts yeah ??

I'm kind of interested in how you have the receiver installed in the boat. I have Spektrum in my boat and never had a problem.

Can you provide some pix?

Thanks.

Doh on the AA i was thinking NIMH cells.

What is or are your boats made of also
Like Andy Said Pics please

i have 3 of the newer 3000 receivers... they all glitch with my dx2.0.... always in the same part of the lake... so far i m unimpressed with my spektrum set up... i expected wonders coming from my aquacraft rTR AM crapola... i also tried the spektrum with a 4 cell AA rx pack... glitching again, same with my old AM system... weird since my friends FM (jr) and his cheapo Am rtr are fine...

it s a glass sv27... i ll post a couple of snaps later... gotta run to work... stock take

In the same part of the lake, you say. Can you describe what that part would be? Perhaps you have a lot of foliage nearby the line-of-site? Or maybe you're standing down on the shoreline instead of above it some? The installation in the boat is critical - just like the old days of FM, you need to make sure your antenna is up away from the water. All these things make a difference.

lake is man made surrounded by loads of houses.... big lake, approx 300 acres... always stops in the same position... clear line of sight and not super far in terms of distance... i ll prolly be back there today since it s only about a mile from my house... i ll snap a couple of shot there as well...


hang on a sec and i ll post a few of the boat...

cheers

Hard to tell from that angle, but it looks like you have 1/2 the antenna down inside the boat.

If it were my hull, I would move it (out of the radio box) back to the transom and up against the bottom of the deck. The antenna on an SR3000 is about 8" long - you want it up and out as much as possible.

It looks like you're using a 75MHz arrangement, where you could get away with losing 4" w/o a problem. What you show there is about the performance equivalent of cutting your 75MHz antenna in half.

Here's an SR3000 in my N2 rigger. I have NO range problems with this.

yeah, there is about 4" of antenna showing maybe 1/2" more... my next step is to lose the box and try that out... hopefully it ll work... so do i need to drip the rx before mounting it on the transom ?? boat doesn t take on water, occasionally a ounce or so at the most...

thanks andy

[AndyKunz]

I have both coated (same DP 270 I used on my ESCs) and uncoated ones. I haven't had any problems yet, but I haven't sunk any yet either. If you do water-proof that one, be careful around the bind button.

The 3000 in the picture is uncoated.

I removed the case and sprayed my 3000 receiver with CorrosionX over a year ago, and in spite of getting completely submerged when I had a hull breach, that receiver has performed flawlessly. I just opened it up, unplugged the boards and blew out the water. Left it in the sun for a few hours (@90F) and it was ready to go. I prefer not to "dip" in a permanent potting material, especially with the moving parts. This is not built like a 75 mHz receiver....

In my Titan 40 I mount the receiver right at the transom so the maximum amount of antenna is out of the hull. The only problem was when a cheap 5-cell pack lost a cell....I lost radio control and the boat went into failsafe. No damage.
