Hello everyone,
I have been able to buy a number of Norvel 0.061 Big Mig start up control line engines. They were new and unused and at a good price. My query concerns the tanks on these engines. There is a pick up line that goes to the rear outside wall. This finishes up about a third the way up the tank rear face. There is a vent that goes from top to bottom of the tank and is bent to face into the slipstream. OK it looks a sort of stunt tank of the old fashioned kind, but without a vent going from the tank bottom and finishing just below tank top.
Does anyone know if they work or not? If not, has anyone tried a modification to make it work? Seems a pity to throw them away! I know the answer is to try them and see, but the combination is meant to be fire wall mounted and the tank adds about 1.25 inches. So the engine is that much further forward. Short of ripping apart a good 1/2 A stunter, I have nothing to try the combo out on! Anyone got any experience with these engine / tank units?
