LOL I actually used to do that with r/c cars when I was younger. When NiCd batteries were still around.

I managed to plug the battery into itself once.

That was awesome.

Hey all,
I see more newcomers are following this build, I think that is so cool. And thanks for all the great comments.

I will post pics in the next few days of what I have gotten done.

If you go back a bunch of pages you will see where we all discussed the power system for my B-36, at the time I did about 20-30 test with the battery being about 8" from the ESC, and then the motor having a long lead (max 36") This was so I could keep the batteries at the leading edge of the wing to get my CG correct. I was really afraid of adding caps and getting that all right. One reason for loving electrics on twins is if done right you will never have a engine failure on take off, and if I get the caps wrong I could have a ESC fail. But after really sitting back and looking at all the things that it takes to do the different motor set-ups, I now see that caps are really the only way to go. This way I need no panel access in my nacelles. A year ago I had hoped to get my ESC on my firewall by my motor mount, but then when I found out about adding caps it scared me away from that idea, now I am back to mounting the cap board/ESC to the firewall, and running my battery leads to the front of the wing.

Thanks all,
Dag

That being said, please take the rest of my post with a VERY light hearted approach.

I saw this post from you:



And couldn't help but smile. YEARS ago, I LOVED for a new Flight Instructor Applicant to show up in my oral room and drop that little gem. The conversation goes something like this: So.... let me get this straight. The yoke controls airspeed and the throttle controls altitude? Just pull back on the yoke if I want to slow down?

You and I both know that pitch and power are absolutely linked. You can't change one without changing the other. And yes... there are 2 ways of explaining this concept, the Navy way and the Airline way. But on occasion I would have a student try to defend the simplicity of your statement to the death. It usually took about 30 minutes before the applicant was a quivering pile of goo infront of the chalkboard trying to defend his idea. I just always got a kick out watching someone fall on their sword trying to defend an idea they didn't understand. Maybe I'm just sick and twisted and enjoyed the suffering of others.

Anyhoo.... just a funny memory for me and wanted you to know you made me smile. Ok, back to lurking.
Another thing that get people is.... the only thing a wing knows is airspeed..... wrong, angle of attack.

I took a friend up once in a Piper Cherokee 140 with the hershey bar wing. We were at about 4500' and he had told me that pitch is what you use to gain altitude, and he does it all the time with his RC planes. I said that his RC plane was so over powered it was hard for him to see what was really going on. So I told him to climb to 5500' and try to do it at about 200-300fpm. Well at about 5000' we were down to 55mph from 90, the stall horn goes off, and we stalled, and it was a stall that even took me a bit of guard as when the wing dropped we ended up on our sides at 90 degrees, not sure if anyone knows, but the hershey bar wing was a really bad wing once you stalled it.

I then took him through a few accelerated stalls, he could not believe you could stall a wing at 110 mph. The 140 was a pig, and stalled without a bunch of warning, but it showed him a wing can stall at any speed, it is all angle of attach.

Rock On

Dag

My own rc flying experience is limited to two beginner planes, but knowing a thing or two about structural engineering, I'm completely impressed by this immense undertaking! Your patience and level of craftsmanship is awesome!

By quickly skimming the thread (about 10 pages at a time), I understand you have overcome problems in more than one area. I'm definitely gonna follow your project till the end.

Keep up the good work, and good luck!
Thanks!
It has been a long and hard road, but a ton of fun, structurally I really feel good, but I also felt good about wife 1.0 (she had a bad mainframe). If my wing design works, I am set, and I just can't wait to get her into the air.

Thanks, Dag

I would never be able to build anything like this I know I don't have the skills but I can dream, and live vicariously through your build. Thank you so much Dag for bringing it to us. By the way my kids are knocked out by it too.
Changing the subject a bit, you've got to love the Kiwis for their front but take a look at Thompson's safety video

I really like this, they need to have more kids doing things, like maybe running our government.

Thanks, Dag

Come on, You Can Do It!!!
I would love a SH-3 Sea King with about a 144" rotor.

Not sure where I could get the parts for a 144" rotor, but man would that be cool.

Thanks, Dag

You didn't help any... your comment alone makes me understand the kind of person you are.. My ignore list might just grow a little bigger later on today..

Wasn't intended to be insulting. I should have put a smiley face after the comment to indicate non-seriousness. No offense to anybody!

Whatever your beef is with Dag, perhaps the fact he's doing something big or getting praise or whatever, let it go, no one here is going to be persuaded by your rambling arguments. I've looked at enough of your posts to see you have left a smoking trail of arguments and rants to anyone that gets in your way from users to moderators, if you're that angry in life just log off and go find something that you enjoy, we don't have time to play this game. This place is about enjoying the hobby and all that goes with it, there is no reason for you to come in guns blazing, many of us are very friendly people until pushed too far, let's keep things on the friendly side and all enjoy...
