New Plunger..
I ordered a new plunger on my last batch, but it would not work in the old style gun...
Guess thats what I get for being "older then dirt"
I will just order a new gun with the next batch...and will have a spare plunger too!!

Thx Stan

That is a pretty cool looking machine. There's a lot of room in there for the cockpit and other interior details!!! What's your plan for the sliding side doors? Is there a kit or do you have to build them from scratch?

Andrew,

I have the fitting kit for the sliders and cockpit doors from Vario. It included functional hinges for the cockpit doors and the slider kit for the cabin doors.

I have yet to get that far up the creek however, I may use parts of the slider kit and some scratch work depending on how well the slider tracks work.

UIH,

Butch

Room Available...
OK Butch, first you need to tell me what UIH is??

Did you mod the mechanics to get this much room?? I do not remember seeing that much under the mechanics in Sandy's...

You do have some "open area" for now... I am sure it will fill up quickly though...
What will you be running for power set up.. 2x6s 10,000's??

Gonna be a sweet set up...

Stan,

UIH,

"UIH" Up-In-Here.

Its a song from DMX several years back. Many years ago myself and the pilots that fly my 76 adopted it, and it is used as;

hello, goodbye, no-way, way, would you look at the t!ts on that, etc. It is a term of endearment. Its all good.

Sandy has an under-slung motor in his blow hole, which is direct drive, where this will have the motor mounted on top and forward of the main shaft and be belt driven. This is Sandys design which uses his shaft and bearing block as a direct drive, but uses Cquinby's/ NickK's motor mount and belt drive to drive the system. Using the belt gives a little more adjustability of gearing and speeds whereas the direct drive is limited by motor KV and voltage.

I am benefiting from the the design and testing these forerunners carved in the jungle of scale model blow holes. The structure is scratch built, while keeping in mind, the added weight this will carry, due to the weight of the batteries and meeting some other structural issues not needed with a nitro installation.

UIH,

Butch

UIH,

Here is a pic of the powertrain.

There will be a 15mm belt driving the impeller shaft with a toothed pulley, just above the clutch bell, from the motor which will also use a toothed pulley. There will be spacers between the pulley above the clutch bell to keep the bell from lifting.

The pulleys can be anywhere from 20t to 26t on either the motor or the impeller shaft so it gives some gearing options.

cool looking Butch! I see what looks like a clutch bell/gear so I am assuming this system has a clutch?

The proper use of "UIH" in this case meaning "Yes"

Thanks cptn,

The forward and aft dog house will be pretty simple to remove so we can look at the schnizzle.

I got some Jewelry Thursday. I whipped together a mount for the V-Bar sensor and got the linkages for the head put together. I need to do some more work on the mount. Nothing is final adjusted and I will change the PC links to turnbuckles sometime soon.

Getting close

UIH,

I actually got to a point where I needed to know a basic weight. Its better to know during the build where you are on weight opposed to trying to cut weight further down the line

The fuse is still fairly raw. The complete mechanics are installed. The tail servos is sitting in the duct all the way in the back. The ESC and cockpit structure is just thrown into the cockpit area to give an clue which I am lacking. The upper cowlings are also installed.

There are no windows or doors installed at this time.

11.4 lbs w/o batts and 19.4 w batts. The batts are 4-ea Pulse 5000 mah 65c.

Overall I am ok with the weight at this time however I will be looking to trim where possible.

UIH,

B

Wow 8Lbs worth of batteries that's cool

Do you need to go with 65c? I thought that scale birds could get away with a lower c rating.

What about blades? Is that additional weight that you will have to consider as well?
