I bought a GP 1/3 scale Pitts that has a ZDZ 40 RV-L in it. The engine is side exhaust with a Pitts style muffler that, from the pictures, is probably the Supersonic unit on the R/C showcase site
Unfortunately, I have no manual for the motor. I downloaded a 5 page manual from the zdz.cz website, but it's not any help as far a setting up the electrical system. While I've been in the hobby thirty years and have had dozens of two and four strokes, this is my first gasser. I have several questions:
1. This engine has a Falkon ignition module and Bing carburetor. Carb is easy thanks to the FAQ on the RCshowcase website, but how do I hook up the ignition module? It has a three wire Futaba or hitec type plug on it. From what I've read, it should just go to a battery pack. What size would the battery be, and what is the third wire for?
2. The builder has a small switch mounted on the firewall, like this: http://www3.towerhobbies.com/cgi-bin...?&I=LXJ776&P=0
A servo shoves a pushrod into it. I'm assuming this is a kill switch like a lawnmower or weed eater has, or would it be inline with the battery pack?. The wires are not attached to anything, and I didn't see any obvious attachment points on the engine. Where should I attach them?
3. There are two fuel lines going out the fuel tank, both terminating outside the body with something like a fuel dot, except they have a thumbscrew that threads into the openings, and are sealed with an O-Ring. The fill line on the clunk has a tee that goes to the carb, while the vent line has no engine or crankcase connection, other than the well sealed cap. Do I just remove the vent cover before running, or is there some line missing from the carb that would pressurize the tank like a chainsaw uses to get fuel to the carb?
4. I'm assuming the fitting on the muffler is for smoke. If so, I was going to get the Megasmoke Plus from RCshowcase. I think I can eliminate the extra servo for the kill switch if I go that route. Am I headed down the right track, or should I get the unit w/o the switch and stick with what I have? Reliability and safety are more important than a couple bucks to me. How well does this unit make smoke?
Thanks for any and all help.
