Finally got the OS 46 LA on my Super Decathalon fired up last night. It fired right up! Was happy about that. Ran on tank of fuel through. Would like to run at least two more tanks through it prior to it's maiden flight. It feels like the engine should have enough power to fly the plane just fine. I decided I wasn't happy with the fuel tank set up. I used the hardware that came with the plane (all plastic). I ended up putting in a sullivan 10 0z tank with brass tubing. I wire tied all the connections. This sullivan tank is clear, making it easy to see the vent tube and clunk. I also added the third line for filling. I don't understand why there isn't some place that you can buy a preassembled tank, with the clunk, vent tubes etc... already in place. This is the most critical part of the plane! So there's my suggestion. Could call it the "ARF" (All Ready to Fuel) fuel tank! HA! Would sure give me peace of mind and make the build one heck of lot easier. For me getting the fuel tank setup is the most difficult part of the build. Not that is extremely difficult. But it is time consuming and one of the things you worry about the most cause you want to be double sure you got it right. Other than that the build for this ARF went extremely well. All I have left to do is secure the fuel tank, battery and Rx and she's ready for take off. Hope to maiden that SD this weekend, or maybe even tonight. I want to thank everyone for all the advice during putting her together. This will be my last ARF for awhile. Not retired yet, just don't have the time to work on them. Will buy RTF's for my next planes. Most likely used. Wife says I'm obsessed!! HAHA!! I told her that she was absolutely correct!! Ah but a sweet obsession!! I honestly would sell my harley to buy more planes!! That would give me more romm in the garage! Now if I could just get her as obsessed as I am about flying!!
