Hello Guys,

Quick question, has anyone fitted the GV-1 to the Raptor 50 V2 ?? The
fittings for the Sensor are for either 30 size or 60 size engines..... any
advice would be appreciated.

Cheers,

Collin.

best advice might be to use an optical sensor. Look into it (try googling
for "gv1 optical sensor" in the newsgroups).

Modify the bracket closest to the desired length. That'd be the
longest/biggest one.

Sorry, but that is crap advice. There is nothing wrong with the standard
sensor.
The optical sensor has it's issues - same as the hall effect - why make the
thing cost more money and invalidate your warranty to fix a problem you
don't have ? Yes, the optical may be easier to set-up but by that it means
it only takes a couple of minutes to line it up compared with three minutes
for the standard sensor.

hehe I was waiting for a response like that :-) I did say 'might'

What's the hall effect? Does it really invalidate the warranty?

It can fall apart after a while tho Andy. I rate the opticals pretty highly,
much less hassle than the standard sensor.

I have run governors since about March last year with the only precaution
being a piece of heatshrink over the the sensor. I have not had a failure,
and none of the sensors look like they are falling apart. I must have run
at least 50 gallons of fuel in that time. Cost of heatshrink is pence and
most of us have it in or toolbox, and there can be no question of any
warranty issues. The optical sensor costs at least £8 and is not the
easiest thing to get hold of, and if past performance is anything to go by,
Ripmax (and Macgregors) do everything they can to wriggle out of a warranty
claim.
I appreciate it is easier to set up once you have sorted your reflector out,
but I cannot see their real worth if the original performs perfectly with
one minor precaution. It's not as if the optical sensor doesn't require a
degree of protection too...

Now I know that there are many people with failures, but have there been any
that have taken the recommended precautions ? I don't want to start a war
here - I just really cannot see the point of this change. Perhaps if a
sensor fails on me (or anyone I ever fly with) then I will change my mind.
Until then I'm sticking with the standard sensor.

Untrue - the sensors cost about a quid and a half and you can get them from
Pacer electronics. Apart from that, you need 2 resistors and a servo lead -
about another 2 quid. About £3.50 total.

I don't agree that there's anything much wrong with the original either. My
case smashed after about 2 gallons but the footery bit inside was still ok.
I just glued the case back together using 5 min epoxy with some thread
wrapped around it. It's never failed since.

I'd agree with you Andy.

I've run a GV-1 for almost a year now with no problems regarding the
original sensor. By simply following the instructions and ensuring a secure
fitting, I can't see why the sensor should give me any problems. I suspect
that many of the problem sensors are caused by heli pilots who treat
cleaning their heli as something to be avoided at all costs, the fuel/oil
residue left on the sensor has the same adverse effect that it can have on
the rest of the radio gear.

I suspect that anyone having problems with the original servo would have the
same problems with an optical unit, with the added hassle of having to
ensure that the optics and reflective surface kept clean.

When I did some investigation into this I couldn't get a price less than
about £4.50 for the sensor, so £1.50 is bloody good going. I did try
www.pacer.co.uk but couldn't get a price. Out of interest what sensor model
do you use and who is your supplier ?

[Please don't take this as me disbeleiving - I am genuinely interested]

I've got govs on my heli's that haven't failed too Andy, but I've seen two
that have (one was mine). No major damage on one, but it did need to have
the sensor internals transplanted to another holder, the other one was dead
coz the fan tore it up. Now if a replacement sensor from Futaba was a
reasonable price (they're not reasonably priced at all IMO at close on 50
quid apiece) I'd go with the original, but the opto is as easy to fit and
costs about 4 quid tops. And it works as well as the magnetic version. And
there's no magnet to glue in or fall out or eat the sensor:-))

Cost of heatshrink is pence and

I like the heatshrink idea very much. So much in fact, that I'll be sleeving
mine very shortly. I still don't see a warranty issue though, because like I
say, who knows what's been attachd to the gov?

The optical sensor costs at least £8 and is not the

Actually, the opto kits proved easier to get than the original Futaba items
for me and they didn't cost anything like 8 quid. I couldn't get an original
on this side of the pond for love nor money. Even Ripmax didn't have any in
stock and they said they wouldn't send me one even if they had because
"others" had them on back order. No shop I contacted had them either. Peter
Wales sent me one from Florida which is still in use, but I had no problem
getting the opto sensors when I decided to give them a try.

That minor precaution shouldn't be necessary though but SOMETHING has to be
done to stop fuel from eroding the plastic holder. Fuel DOES make it
brittle.

At 2 quid for the read head, it's not an issue.

What ARE the recommended precautions Andy? I can't say I've looked at the
destructions lately, but I can't remember reading anything about sleeving
them when I did.

I don't want to start a war

Cost, availabilty, ease of set up (no measuring for magnets, no drilling).

That's what I did:-)

That's assuming you can GET on in the UK. I couldn't.

Mine was 49 dollars from some place in the US (Peter Wales got it and sent
it to me , so I'm not sure which shop it came from) plus 14 UKP for posting
via DHL.

Worked out at close enough to 50 quid as makes no difference.
