Yup, I got that I was comparing his home brewed floats to the pic of the real ones...

This is going to be sweet! We will have a larger pool at HSM 2013 for you to land! I love the Calypso idea!

Gonzo: I hope it's a good size pool because this is a pretty good sized 300.

Ken: I may take you up on that offer bud.

Bummer that calypso is retired. I wonder where she sits? It would make a great photo OP.

OK, forget velcro for the lipo strap... I machined a cross strap out of aluminum at work. Here's the finished lipo mount. I left room for larger lipos if the need arrises.

She's alive!!! I maidened the 300 this past week and she flys great! I have 6 flights on the airframe and I'm getting ready to blow it apart for details and paint. I bought a 1/4 scale engine kit from Boyd and I'll mount the halves on either side of the mechs. It should look way better that the frames. I'm running 1140 rpm HS and she's rock solid in the air, just hangs in a nice hover and lands smoooooth. Overall, this has made me want the 1/3 scale 300 from vario...

Thanks Gonzo I can't wait for this years SM event! I'm hoping to have the 300 completely detailed out and on floats.

Here's a pic of my Lama maiden from Sunday morning. I'm bringing this one also. I just haven't decided on a paint scheme yet...any ideas? Maybe Euro press heli, or something colorful that hasn't been done to death already by our friends across the pond
Happy new year my friend, Barry

Here's the latest on this build. I have been flying this one for a while and it's all sorted out. So, I have been working on the details. I have the mock engine built, ready for paint and I just finished the gas tanks.

The tank straps are styrene strap and the gas caps are aluminum that I spun up on the lathe. After I paint the tanks I'll come back and paint the straps black. I also monted the top crash bar on the fuse. I mounted it in the correct position. I have seen so many of these where that bar is mounted way too high, or way too far forward than the real heli.

Thanks to Taylor and Ken I'll have enough detail pics to get it all figured out. Next up on the list is mounting the dummy engine, then the drive belt cover, prime the heli then lay down access panels and rivets. Stay tuned...

Barry,

The 300C looks really good.

I've been flying mine since 2005, and used the original wire drive for 4-5 years. It was adequate with a rate mode gyro because the gyro didn't work the tail too hard. But, when I 'upgraded' to a GY-401 and used heading hold mode, you could hear all sorts of wind-up from that wire drive. It concerned me a bit, but I flew it for a season or two anyway to test it out. It was fine, other than the sound. But, in the back of my mind was the thought that the wire drive would snap, as it has, on earlier machines of mine. I had two tail failures in the 80's due to the piano wire failing, and didn't really want to repeat it again. So I replaced the wire drive with a torque tube and articulated joints. That drive system has worked perfectly, has no windup, and is quite robust. If you run your tail in heading hold mode, you might consider doing the same modification.

Looking Good!!!
Barry it is coming together nicely.. I did not know that these mechanics weren't TT tail drive...
I agree with Joel 150% on that upgrade...it might take a little more time to do, but well worth the investment... I have also lost a couple of the old style wire drives over the years (or GOOD OLD DAYS!!!:eek
Good info Joel...

Hi Joel, Stan, thanks for the compliments and good advice I had really questioned this set up when I first built the heli. Vario puts a bend in the tail boom and they have a little plastic guide that the wire goes through. This makes the wire run with a gentle arc, so I can hear the wire drive when I'm spooling up. I can see this failing over time. I think I'll upgrade it to a contour drive or TQ tube after scale masters, as I just don't have the time at the moment (trying to get her in paint). I'm mounting the dummy engine and will update the post tomorrow night.

If you go the torque tube route, you can use a single bearing in the middle (approximately) of the shaft to support it. You won't be able to get three bearings in there given the angle of the bend in the tube.

Anyway, the original design works fine, so no need to worry at this early stage. But, it is certainly more convenient to replace it before final assembly. I got good at replacing it afterwards, but it's no joy once you have the rear wired for lights!! Removing all those pieces is a puzzle when you have wires to work around. :-)

Thanks for the heads up Joel. I will most likely just end up fixing it after scale masters, just because of time and cash constraints. I have to buy the correct head for my vario R22 and that's another $620+ out of the heli budget...

So, I mounted the dummy engine in the 300 today. I have to say, it looks pretty darn cool (ignore the slightly crooked rocker cover, it's just tacked on for the pics) I'm not done with it, as it still needs the exhaust manifolds and pushrod tubes installed, then paint, but you get the idea. I would have opted for a more inboard mounting location, but I was limited by the skyfox frame and the location of my lipos. The lipos mount sideways on a custom tray directly under the mechs. The heli flies so well, that I have no intention of moving the lipos and changing the CG. I may build a cooling shroud to close out the back section a little bit, we'll see. That's why I left the wood tabs on each end of the motor, just in case I need them to mount a shroud. Measure twice, cut once...

So, I moved on to the detail stage here. I laid down rivets on the vert/hor stabs today. It went quick, the most time consuming aspect was drawing the lines and spacing the rivets. This is the first time that I have done rivets and I think they came out pretty good. I'll get even better with time...

This heli is coming along well in the detail dept.. I'm getting ready to add rivets and the interior. I bought the scale dash panels from Joe at East Coast Scale Helis and I'll be making the dash housing to fit them in. If anyone knows where I can get good looking seats for this heli, let me know.

I wanted to share with you guys how I made the lipo tray easily removable. It pins at the rear with 2 small hitch pins. I have 8-32 allens that thread through the existing skyfox rear X-member. The allens are cross drilled for the hitch pins. So I just pull the pins and the back of the tray drops down. The front of the tray is hooked on the front X-member.

floats
Barry

This is what I did for the floats on my bell 47.
I made the end cap out of fiberglass. I ran the wires for the battery through the struts to keep them out of sight, I will put a 6s 5000 pack in each float.

Hey Donnie, your floats look super cool, very realistic! I need to pick your brain about how you made these. Do you have step by step pics of the build process? It also looks like you designed your own mechs.
