I have a Powerline Hobbies Nepturn sea plane. I am thinking about putting a 54 four cycle on this. Has anyone flown this setup? Any opinions on this.? Also would anyone have the manual for this that they would be willing to scan an e-mail to me? Is there a website that might have this info?

Thanks

Quicktech hobbys,

Larry Quick handles the Powerline version of the Neptune. Nice guy, i have bought two Neptunes from him, but i did'nt keep the instructions unfortunitely. They go together so easily, you could likely figure it out once you start playing with the parts in the kit.

The three piece spar gets glued together first, then join the wing halfs, then set-up your wing hold down dowels, then your wing hold down bolts. When the wing is bolted to the fuse, you can then glue the stab to the fin, and add the braces. Then your hinging can be done. The coolest way to set up your engine pod is to lightly clamp it in a vise on your bench, this puts it right in front of you and free's up both hands Theirs no up or down thrust in bolting up the engine, a slight amount of up thrust is built into the fuse where the pod glues to it, so don't change anything there. The fuel tank set-up was a head scratcher on the first one, and a snap on the second one. what you find is that after the tank is in place on the pod, the rear section of the cowl will not go all the way on!!!![&o] The cure is suprisingly simple though Just use your heatgun and warm up the 4 corners of the rear of the tank and push in the corners with your thumb or the bench, this simple step adds a little more radius to the tank corners and gives just enough clearence that the cowl JUST fits perfectly. The other option is to warm up the whole back of the cowl and then push it against the tank. I don't like this option, because it leaves four perminent out-bumps on the cowl that are'nt very atractive. That basicly completes the airframe, then you just do your radio install and linkages as normal, and C/G is 102mm back from the leading edge of the wing as a starting point. You want to silicone the wingtip floats onto the wing, DON'T use the stupid sticky back crap thats supplied (ask me how i know this) Make sure you seal the wing/fuse joint well, the plane slides on the water when turning at speed (WAY COOL FUN TO DO POWERSLIDES) but doing that sends a high preasure wake of water right at the wing/fuse joint, and anything less than a perfect seal there results in water in the fuse (ask me how i know that one too)

You will LOVE the Neptune, it's the latest technology and best performing of the whole cloaned series (seamaster, seamonster etc.) and they have absolutely no bad habbits. Their just a ball to fly. My Fathers two both have OS-46s in them, and my newest one will have a OS-50sx in it. These planes come out very light. Your 54 four stroke will also fly it fine. With the 46 and 50 two strokes, we had to add 2oz. into the inside of the nosecone to C/G them, i have no idea if you'd need the same with the four stroke. My Dad uses a three blade prop on his, i'm on the fence on that one.

Scott,

Thanks
