Hello there,I'm totally new to r/c aircraft.I have an Arising star trainer matched with a "SC" .46a,still waiting for the radio set,which is going to be a "GWS 6".So far things are going well but I have a few questions :- Does the engine need an air filter? and On the fuel fill pipe (oppposite end to the tank),where the fuel is put in do I need to put some device to stop fuel running back out.
Cheers Captain (long live The Damned)

Your normally shouldn't need any sort of air filter. I've never seen one used on an airplane. The only time I can see it being necessary is if you fly off an extremely dusty field.

As for the fuel fill line, you can get an aluminum or plastic plug which has a barb and stays in place well. Some people just use a screw.

No, it's not necessary to have an air filter over the carb. You can put one on if you want, but I've never seen a guy with one at our club and have never personally had a problem without one; however, a fuel filter is a good idea. You could install one on the line going to the carb (between tank and carb). When you fill up, take the line off the fuel filter (NOT the carb) to fill.

That's a nice airplane. Want to keep it nice? Find an instructor at a local club. These R/C airplanes are MUCH more difficult to fly than most people realize. If you still aren't sold on joining a club take a look at my latest blog entry.

By the way, the carb looks off center... Is it nice and tight? If not, push on the carb with your thumb as you tighten to get a good tight fit. In fact, it looks like you're missing a screw on the carb. Before you fly make sure you get those clevis keepers (the small bit on fuel line at the end of the control rods) on the clevis. Another good idea is to point the muffler down away from the wing. This way the crud can get out of the engine easier and your airplane will be cleaner. To aim the muffler loosen the bolt at the back and remove. Then loosen the screw in the front. That screw actually goes all the way from the front to the back. Those threads you took the bolt out from are part of that screw. Twist the back of the muffler to aim it, then re-tighten the screw in front and put the bolt back on.

Everyone just about said it....

No you don't need a air filter, but some use a piece of Womans Nylon Stocking with a O-ring, and they slide it over the Carb. It doesn't effect the power of the motor... and it does keep the bugs out.


You fuel your plane by disconnecting the fuel line from the carb. It's the same line that runs to your fuel tank. Disconnect the line connected to your muffler... when the fuel runs out of the line attatched to your muffler, then you know your tank is full. Re-connect everything and you are good to go. Welcome to our hobby. Hope you have a flight instructor... It will make your plane last longer.

Someone has already noticed that the carb isn't bolted in securely. Hope you didn't lose the missing screws. Just from curiosity, why did you remove those? And hope the O-ring is still there if there was one.

But another question begs asking. It is obvious that the engine isn't yet bolted to the motor mount BUT.......
What is that fuel hose coming around the bottom that ends right below the carb intake? Is it just the delivery line looped around?

A suggestion..... I've no experience with SC engines, but an 11x7 prop on a brand new 46 might be on the heavy load side of things. You might get better trainer like performance with a prop with less pitch. And it might be easier on the engine to boot.

Good Observation! [&:] I didn't notice that until you had mentioned that... and those are good questions?

Many thanks to one and all.At the moment the plane is still in the build process,and yes the carb screws haven't been put in yet.The compoments have only been put together for the purpose of getting it right.The engine has'nt been bolted in yet either.This is the first plane that I have built,and will be the first for me to fly.
I will be looking to join a local club,so hopefully they can teach me to fly.Thanks for the help so far.Most appreciated.

Ok there,no the engine isn't bolted in yet,the bolts were missing from the kit,I have the screws for the carb and the 'O' ring but they came unconnected as packaged.As for the prop some advice would be good,I got the one that was in the engine leaflet table guide.

something a bit flatter like a 11x6 or 12x6 would make it fly a little slower (a bit better to learn on)

A 12x6 is really almost too big for a .46 engine.

Nice one thanks,the guy on the phone when I ordered seemed a bit suprised but still sold it too me,anyway I think I will try the 11x6 prop.Cheers Captain

sorry ken, i was working on the principal that if you go down 1 in pitch size youd got up one in diameter... but a 11x6 should be alright
