Are they reliable (thats what the topic is about)? I've had my Fox 800mW VTx running regularly for more than a year now with no issues. A survey among the users should tell.

Its what they used to say about the Japanese products in the 50's and 60's.
I'm sure these guys will improve their design and QA/QC over time.

@Talajouy,
Can you open up your Lawmate for a side by side comparison?
I did, read the thread from first page.
Short cut is here

If you think solder will melt you are not installing the tx very well and have some serious issues with proper take off timeing,, run your motor before you take off to cool the tx, if need be


and can see why extra solder would be a great thing for around the antenna connector
for crash resistance etc.

and do not have any problems with the fox tx's

edit except maybe with the fatsharks

many mods are possable

david22's hot glue mod works wonders for vibrations however lol
David,

You like this TX or not, is it working good for you or not, you happy with the money you paid or not..... USING SOLDER FOR HEAT SINK IS NOT ACCEPTABLE AND STANDARD ON ELECTRONIC CIRCUITS.

The 800Mw is better in that point, I opened mine and show you the photo before, its right here.

Who ever said solder works for heat sink?

Yes I like the 800 and the 1.5 watt tx

Then we are agree on the same points, Those flux around parts specially the output HF circuit makes those problem like, "It is working good/better in certain channels CH7-8-9" and "picture getting noisy by TX getting hot".
And the high gain harmonics also is a weakness in design.
Fairly the FOX AV links are working equal/good for the money you pay, but I do not consider them as a good AV link.
Otherwise I love to buy staff half a price (~57$FOX ~120$Lawmate) and they work great for me.

Is this the transmitter you are talking about???!!!!!

But this is not the 700mw or 800mw FOX that I'm talking about, you did not even look at the pictures, if you did then you should realize we are talking about some thing else.

yes that is the tx in the link that works well and is lower in price

you really are missing the point and seem to be mixed up rather than me

go back and read my posts

I am happy with the fox 800 and fox 1.5 watt tx as i said

For those complaining about the looks of the inside of the transmitter, I say that it works and is cheap. Cleaner is more expensive. Given that it works, give me cheap.

The inside of your bowel does not look very nice either.

Take it from someone that does electronics reliability and MTBF testing on a regular basis that this is not how it works. For example flux residue from solder paste will have small particles of solder in it still, if the flux reflows or softens due to the Tx heating up it could cause a short, detune the PLL, etc, etc. all valid reasons for the Tx acting up, or malfunctioning when in use.

So 'given that it works' is relative and says nothing about reliability, please keep that in mind.

Cheers,

Sander.

Ps. Talajouy is right for cleaning up these transmitters himself, it'll make them all the more reliable. But this is not something to be attempted unless you know how.

Cheers,

Sander.

What frequencies does this transmit on? Link only says 1.2G in one place and 0.9G/1.2G in another place.

What frequencies worked well for you? This helps tell what frequency the antenna is made for.

Sorry if you already posted it, but I don't remember it if you did.

For under $30 shipped I may have to try one.

On the other hand, if I have to pay maybe $15 extra for an antenna on the correct frequency and wire my own connectors (no transmitter pigtail), I may just fall back on the BOB for $58 shipped which came with a 1280 antenna (and transmitter pigtail and receiver and receiver antenna and 2 power supplies and RCA AV cables) when I got mine over a year ago.

Thanks,
Cliff

Would acetone and tooth brush do the trick?

I've got that same transmitter quite a while back. Mine transmit only on
1200, 1080, 1120 and 1160 MHz i.e CH4,5,6,7
The stock antenna is crap so change mine to DIY pole (RCCam style)
