RE: Help a newbie tune his GST 7.7
I would highly reconment getting the OFNA check valve from tower hobbies. It will definently help your tune greatly. If you get it though you have to lean it a bit more because it helps with the tank pressure. [link]http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXEYG3&P=7[/link]
