DAG, love watching your build, it's on a scale I can't even dream of. FWIW, there are a whole bunch of guys over on RCMF who fly Tony Nijhuis designs, 96" and 132" Lancasters and they figure 50 W/lb gives adequate performance and anything over 75 W/lb is wasted. Ian Walton flew S-Sugar on 45 W/lb initially on 4 brushed motors. 100 W/lb would have been sport category a few years ago, but lipos and brushless motor technology have made us power crazy. If you are trying for scale-looking flight you have more power than you will ever need.

Relax and focus on this beautiful build.

Cheers,
Jeff

P.S. the Zyrtec is pretty effective on colds too.

Hi dag, looking awesome, very inspiring indeed. Would love to see it one day and hope I can when I get to the US soon.
As to the putz that send you the email stating that you need 150w/lb, he got his personal intake and exhaust mixed up big time, I am flying a 11lb 3oz Pattern plane at the moment with a calculated 1550w brushless/lipo setup,( 138w/lb) and I have unlimited vertical with that. You figures of 100-110 w/lb should give it a nice lively performance envelope, and scale should be nice and relaxed.
get well soon
cheers

Hey, I had a case of the cruds a couple weeks ago, and three other people I know (one in Mexico City! Ha!) had something like it. I only missed one day of work, but it took about a week to get completely out of the funk.

Not trying to be a downer, just saying it's "going around."

Dag, get well soon! I had a bout of something like that about 3 weels ago. Only lasted a couple of days though.

I would bet money that your power system will be plenty adequate for more than scale performance and probably closer to "sport plane" capabilities.

Not to worry, if your weight comes anywhere near what you calculate, she will fly fine!

Take a break Dag, get better!
Hey don't worry about what other people think about your engineering. Go with what you feel good with!
What you have accomplished is remarkable.
Here I am trying to finish up a big electric sailplane, and haven't got much done and you've built a huge airplane!
But then I jhave been remodelling a room in my house and this has taken up a lot of my time.
It will be an office and my aviation room. I'll post some pictues when I get closer to finishing up. The raw product looks kind of messy, ladders setting around paint cans setting around baseboard taped off, LOL!

With a wing area of 5425 in sq and a weight of 1280 oz (80 lbs), I get a cubic wing loading of 5.5. That puts it in the trainer category. Seems like you have plenty of power.

Dag, they say you should starve a fever and feed a cold. In that case I prescribe an overdose of milk duds and potato chips.However, you need to be aware of the side effects.An overdose of milk duds will make you fat however, an overdose of potato chips will make you fat and thirsty.

PS:You are the engineer.Don't worry about what the uninformed say.Do what you do best.

Here is the story, if my measurements are right this B-36D will break down to fit in my wifes van, if it does I will bring it to SEFF. If it does not I won't have my new trailer yet. It might not be airworthy, but if she fits I will bring her.

I am really looking forward to seeing a few electrics .

Thanks DAG

Ya, Dag that is very easy to do !!

You work at your job already and then you are probably staying up way to late working on this plane...

You have to be because you have gotten so much done in just a few weeks !!

You need to start resting a little at least every other day...

Seeya, Tim

Sorry no rest for the weary! I'm addicted to this thread, it's way better than "Reality TV" or anything on TV for that matter....except for perhaps the Best Planes programs or the Science Channel or maybe the Mega Structures program! Hey wait a minute I think Dag's project qualifies for Mega Structures!
Back To Work I say!

Tim,

Sleep is highly overated...at least it was when I was in my 20s. Ok Friday it is but I'm still checking in everyday just in case Dag is up to a little puttering in the shop.
