Sorry, that's really bad grammer...I wanted to say. Hi David. Do you have any updates for me on the progress (or not) of the Subdriver for the Stingray model submarine featured in this thread, something, anything?

[RCnut]

Got the Subdriver from David today as well as the other bits promised (Sent me back the Kit as well) so I am a happy bunny, As David informed me they were not quite finished but one was as the pictures showed and the other with most of the components there. I am "Confident" that with his help I will get it into the Stingray before the summer ends. Thanks again David.

Mamas -- thank you so much for your patience and understanding during my very tardy and incomplete performance on this job. I will help wherever I can. You are a gentleman and one hell of a Craftsman.

Not an RC version but Built for Andercon with a spinning Ratemaster shot behind a water tank as was the original.

Both together on the "set"

Its been a while but now doing some work on this, After David kindly sent me the WTCs, I have done my best to get one installed and working. I have incorporated the ratemaster rotation inside the main cylinder and replaced the Brushed motor with a Brushless one, I'm only using 3 servos as there is no up and down on the nozzle only left or right. There is way too much slop on the dive planes so they will need to be beefed up and the ratemaster spin mandrell will need tweaking some to get it right. Apart from that Im happy, :)

That is SLICK! How are you going to manage pitch control?

[RCnut]

Hmmm Andy asked me that, The RA Stingray I converted a few years ago to RC worked well and I had used the side fins to control pitch, It was very fast and twitchy in the water but I'm doing the same with this one, We shall see. If it dont work then I will try and sort out a pitch function on the nozzle. Was thinking about actually making the back fins into functioning ones. I dont like the idea of visible control links though.

Keep it simple.

Just put a pair of horizontal von Braun type 'jet-vators' (think: V-2) aft of the yawing pump-jet nozzle. Still hidden within the RateMaster. Hell make them out of clear Acrylic and they will hardly be noticeable. No matter which way the nozzle yaws, the jet will impinge on enough jet-vator to produce the desired pitching moment.

You got the servo and seal in there already, Mamas. Why not use 'em?

Put an angle keeper on that pitch servo and you're in business.

Oh, man! ... you brought some childhood memories to the fore I had long forgotten. What was that guys name -- his 'party' records were a scream. The guy was some sort of Sheldon Cooper type in real life, right?

My Dad introduced me to von Braun when I was a ten-year-old. Never forgot that. He had just finished his work with Disney and was making the technical trade-show tour at the time -- he was still working out of Huntsville I believe.

It was written by Tim Lehrer, who also wrote "poisoning pidgins in the park" and a whole lot of other wonderful, mischievous, songs. He stopped writing and performing after Henry Kissinger was awarded the Nobel Peace Prize because he claimed that awarding the prize to Kissinger made political satire obsolete! Funny guy. Ahh… memories.
