i have some problem when i try to tune the GST's motor.
i saw that after a rectilinear with full trottle gas if i stop the gst and restart...the GST switch off the motor!! why? sometimes it seems to me that the fuel doesn't come to the motor very well.
if i lift the gst and open the gas to the max the motor switch off? i tune the max and the idle but....i don't know.
HELPPP

the fuel is 16%

Sounds like mostly tune and do a check for air leaks. You are also a likely candidate for an ofna ck valve .... right TRD ?? 16 % ??

ofna valve like this: http://www.rcmodelstore.com/catalog/...4445739dc8a084
it isn't ofna but the spirit is the same.

where i must control for air leaks?

This http://www3.towerhobbies.com/cgi-bin...?&I=LXEYG3&P=7 Also up the % of nitro to at least 20% Look thru these threads. MUTT ( TRD ) did a bit on the check valve. Check his gallery.

i must put the filter between tank and carburator and not between tank and muffler pipe, mustn't it?

Filter ? Yes /// Check valve - no

i didn't found the gallery that you said.
This http://www3.towerhobbies.com/cgi-bin...?&I=LXEYG3&P=7 seems to me a simple pump. how can it help me for my problem of switch off?

It is a check valve which will maintain pressure to the tank. It is installed between the muffler and tank. with a more consistant tank pressure, you can refine your tune and also hopefully eliminate half tank lean probs.

Nicely put- I belive pro-line now makes something similar

had anyone cutted the fuel tube? how long must be it ?

It can almost be as long or short as you like within reason. Be sure there are no kinks and avoid having the line touching the head or exhaust. Some like a little extra line between the tank and carb to keep it runing a little longer. Your choice.

my tube is 25 centimeters (9.84252 inches).
isn't it too much long? maybe this is one of some causes of my switching off

Not close to my truck, but that sounds a little on the long side. Is that between the tank and carb ?

yes, between the tank and carb the tube is 9.84252 inches. is it ok or too long?

Is that the way it came from the factory ??

yes, it is!
but a friend's of mine told me that he had to cut a part of mix tube in his revo and all the problems, like mine, resolved.

Give it a try. You can always replace the line.

Just spotted a new check valve out there on the market- ITS made by Orion and looks pretty sweet- has anyone tryed it yet?

Post the link and I will test it for you!!! The flow and working pressure need to be just right!!!

Hi to all.....today i took my GST and i tried a glow #3.......well now i haven't suddenly switch off of the motor! so the problem was the glow #5.
i 'm not able to change the second!! why??? i unscrew the screw but...nothing......i'll do it again
