Next mold dilema.

Dang posted a Delta IV.

Dave it is so hard to find drawings or good pics of any Yankee. Got these other drawings off the net. Boris the guy I got Yankee plans from sells a real nice resin cast 1/350 Yankee II model on ebay.

Pics of the hull and sail plug and plans. Have to ad the end of the missile casing, some final sanding then I can start glassing over plugs. Foam is real dense 2 1/2lbs.

Looking good, Tim. I'll have drawings in hand this afternoon. Might even start in on the master blanks tonight. PLAY TIME! Hey, it's how I spend my holiday!

I found only one good shot of the YANKEE stern in dry-dock. You got any pictures that will help me out with the stabilizers, control surfaces, and propellers, Tim?

Here's an idea: you slice off the ass-end of your foam master and send it to me so I can consolidate the vertical and horizontal stabilizer masters to that cone. That way I produce a master and tool that represents the ass-end of the YANKEE as a homogeneous unit -- the eventual casting is hollow and has the stabilizers attached. Like so:







If we present the stern in such a manner to the customer, it will be much easier for him to integrate it with the hull as he assembles his YANKEE kit. We become rich and world famous!

Plans show nice size dual rudders. Don't see much of a problem. Like Dave said I have a dual motor speed controller where depending on how it is set up during a turn one screw will rotate backwards for a tighter turn. I will get some pics today of the hull and sail plugs and the plans.

Yep,

My Delta 4 will probably turn like a @&*$! I. Going to need a rudder extension on the lower rudder. It will also be interesting to see how effective the stern planes are, they are tiny..

Mine turns quite nicely. Scale rudders without extensions and Kevin's excellent throttle jocky make the magic happen.

I'll be counterpoint and say 688. How are you going to get a Yankee to turn? I have tried a clear rudder extension and an all flying lower rudder on the Delta. Next summer it will have both to see if it will turn in something smaller than the Carmel pond. At least make the rudders larger than scale.

Those two widely spaced screws gives us the opportunity to mix rudder with two ESC's to use differential propeller thrust to assist in yawing the boat.

I was going to see if you would do the appendages and control surfaces as well. I am out of rtv silicone mold stuff and casting resin. I will do the molds for the hull and sail. Saves me a bunch of time.

I'm on it!

Dave I will resend the file to your email.

Got it. And I'll take that file to the local printer and have my hard-copy made to 1/72 scale. May I suggest I also do all control surfaces and stabilizers?

I am pretty sure I sent you the file. File name is 667A Ver 10. File is in 1/144 scale so all you have to do is enlarge it 200%.

Found that file, but for some reason I can't open it. Another format maybe, Tim?
