I hope he has a safe trip. Also for him to say to the guys from the old DOC.

Hi, Bob-

This is a great thread, and I'm much impressed with the e-twin! 'hope you can make it to our area this weekend for the annual Akron/Cleveland Area contest at MAPS.

That twin still looks awesome.

wwwarbird · « **Reply #404 on:** October 06, 2014, 07:14:41 PM »

Cool stuff, can't wait to see the finished "full meal deal".

Allan Perret · « **Reply #405 on:** October 14, 2014, 03:52:08 PM »

Put me down for the plans & CD.
In the last picture there is a lot yaw out relative to lines. Looks like you are at top of wingover. Normal ?

RC Storick · « **Reply #406 on:** October 26, 2014, 12:20:28 PM »

Here is a novel idea to at least try. One pusher and one tractor. I have no clue what it would do.

MikeCoulombe · « **Reply #407 on:** October 26, 2014, 12:54:30 PM »

Very nice Bob, I too would be interested in plans and c/d.

RC Storick · « **Reply #408 on:** October 26, 2014, 03:06:03 PM »

I didn't think of it. Oh well we know that works

Future experiments include trying the props turning the other way. Right now the tops of the props are turning towards the canopy. We’ll try it with the tops of the props turning away from the canopy the next time out. This is a simple matter of switching any two wires on each motor and then switching the props and spinners. I guess, to cover all the bases, we should also try turning both props in the same direction just to be certain that we’ve left no stone unturned…

I feel the need to repeat the advice I gave you on page 5:

motor 1 rotation motor 2 rotation prop 1 prop 2 outcome
L L L L OK
L L L R bad
L L R L bad
L L R R bad
L R L L bad
L R L R good

L R R R bad
R L L L bad
R L L R bad
R L R L good
R L R R bad
R R L L bad
R R L R bad
R R R L bad
R R R R OK

I wouldn't risk it.

Do you have any pictures of these area tabs of yours in this little thread? Or have I missed them somewhere?

Allan Perret · « **Reply #411 on:** November 11, 2014, 07:37:26 AM »

For a fast & easy temporary tab I use a piece of manila folder stock. Fold it half, cut to size and tape it on.

Larry Renger · « **Reply #412 on:** January 04, 2015, 02:39:14 PM »

So, when are you going to do the forward swept canard twin?

I love this thread...

Here I thought the holes were for needle valves! Very nice Bob.

Larry Renger · « **Reply #415 on:** March 08, 2015, 09:14:08 AM »

Anything new on this project?

jfv · « **Reply #416 on:** June 26, 2015, 01:10:56 PM »

Very nice Bob. This twin thing is catching on. Watched Rick Huff kick butt at Brodak in Intermediate with his Pathfinder twin.

Allan Perret · « **Reply #417 on:** June 26, 2015, 01:22:38 PM »

Plans, we need Plans. How many sq.in. wing area for that 68oz ?

Larry Renger · « **Reply #418 on:** June 26, 2015, 04:46:03 PM »

You know, you can get a counter-rotating power setup that would be perfect in the nose of the fuselage! If some is good, more is better, and too much is just right!

Allan Perret · « **Reply #419 on:** June 26, 2015, 04:47:24 PM »

Quote from: Bob Hunt on June 26, 2015, 02:15:44 PM

Plans may be a while yet...

It has 650 square inches of area, but remember, I've quoted the battery on board weight. A glow twin with two .15 size engines would require 8 ounces of fuel (two four ounce tanks), and fuel weighs nominally an ounce per fluid ounce, so it's equivalent to a 60 ounce glow twin without that eight ounces. With the 20 inches of disk span, providing a lot of artificial air blast over the surfaces, and the greatly decreased drag with the retracts, it should do okay.

Later - Bob

You using .014 solids or .018 cables ?

Brent Williams · « **Reply #420 on:** June 28, 2015, 01:35:36 AM »

Very nicely done, Bob!

Airacobra · « **Reply #421 on:** June 30, 2015, 01:33:51 PM »

Great looking plane Bob. I hope I have the opportunity to see it fly.

wwwarbird · « **Reply #422 on:** June 30, 2015, 06:15:05 PM »

It's DONE!

Just in time for the NATS Bob!

Shawn Lenci · « **Reply #423 on:** July 04, 2015, 08:08:44 AM »

Bob,

Glad you are feeling better. Really nice stuff in those photos. Beautiful airplanes, both of them.

I'll bet they look fantastic in the air. Good Luck in Muncie!

Shawn

Jeff Traxler · « **Reply #424 on:** July 04, 2015, 12:06:40 PM »

I'll have guitars in tow.......

Randy Powell · « **Reply #425 on:** July 07, 2015, 11:44:20 AM »

Bob, that is just cool. Great achievement.

Randy Powell · « **Reply #426 on:** July 07, 2015, 01:21:55 PM »

Bet it flies better. Betcha.

Robby Hunt · « **Reply #427 on:** July 07, 2015, 02:27:29 PM »

Deuces are wild...here we see a pair of conspirators, double down on rudders (200% more than a Genesis mind you), and of course, Bubba flashing the international sign for twins...

Robby Hunt · « **Reply #428 on:** July 07, 2015, 03:46:55 PM »

Ahh, the early days...back then the trick was to keep the batteries from rotting...

Troublemakers, all ... Would you buy a used Stunter from these guys?

Have a great NATs, everybody,

Howard Rush · « **Reply #430 on:** July 13, 2015, 09:33:53 PM »

Saw Bob's and Bud's twins today at appearance judging. Very pretty. I lectured Bud on the perils of motor direction and prop direction matching.

Larry Renger · « **Reply #431 on:** July 13, 2015, 09:47:28 PM »

Troublemakers, all ... Would you buy a used Stunter from these guys? In a heartbeat!

All the best.

Jim Oliver · « **Reply #433 on:** April 24, 2016, 10:05:38 PM »

Bob,
Trust you're still checking in---any news on plans for the Second Wind?

Thanks,
Jim

Will Hinton · « **Reply #434 on:** May 07, 2016, 02:49:50 PM »

What guitar ya playing the most these days partner? Wait 'til you see the fretboard Trax brought to me at the end of his last trip your way - many hours of inlay happening to it!

Will Hinton · « **Reply #435 on:** May 08, 2016, 04:27:56 PM »

No hurry at all on the mold, my current one is still good. Jeff brought me back half a dozen necks and fretboards the last trip, I can't make them for the price he gets them for!
Taylor for sure at my end too, except that I play my own instead. But if I weren't building guitars, I would be playing Taylor's. If I were to be honest about it, I mostly use Taylor specs for my setups.

On my electrics I use PRS specs. (And folks wonder why my instruments play so easily.)
That Grand Concert is one fine piece of work. Congrats on that one.
To get back to the control line part of our lives, it is almost total history for me, too, at this time. I hope to revitalize my interest soon, but it's nearly impossible right now. NO guys, I AIN'T selling my PA's!! Or anything else for that matter, I do plan to come back and qualify to fly expert at some time in my life.

john e. holliday · « **Reply #436 on:** May 08, 2016, 05:04:00 PM »

I'll keep watching for yah.

Brent Williams · « **Reply #437 on:** September 07, 2017, 12:51:22 PM »

If these are up for sale, what are you flying these days?

Allan Perret · « **Reply #438 on:** September 07, 2017, 02:04:55 PM »

I'm seriously interested, in plans. Would pay a premium price for this plan.. Any chance of that happening ?

Howard Rush · « **Reply #439 on:** October 21, 2022, 05:08:13 PM »

Worth a bump to call attention to post #575, relevant to a recent discussion with Tim Just about twins.

Rick_Huff · « **Reply #440 on:** October 22, 2022, 02:11:25 PM »

Howard,
Thank you for your chart. It saved me many very embarrasing experiments!
Rick

Dwayne Donnelly · « **Reply #441 on:** October 26, 2022, 12:08:14 PM »

I like the tail of the Turning Point and by chance would not retiring mean you'll be cutting cores for us to buy again?

Ken Culbertson · « **Reply #442 on:** October 26, 2022, 01:06:14 PM »

It is OK by me if you don't get back into the core business. We need you innovating not replicating.

Bet t looks even better in person. But, family and knees keep me home plus other stuff.

john e. holliday · « **Reply #446 on:** May 12, 2023, 01:27:33 PM »

Thanks for the offer Bob, but even if the family let me I would be a pain.

Looks a bit like a ' Space age ' version of this . Thought the picture a bit evocative .
