Very comprehensive checklist. Greater than that of Cessna152.

Love the bit about the wheel chocks.

Rock on.

Hi Dag,

I'm sure this is just my incorrect interpretation but it seems to me that you are setting brakes when the gear is up [After Take-Off]. If you are actually setting them, as opposed to just momentarily engaging them to stop the wheels, you may want to release them in your "Before Landing" checklist.

Regards,

There is no parking brake. It is momentary. It should say "Check" not set.

Work is progress.

Thanks, DAG

FYI...
Latest issue (Apr 2010) of Fly RC has an inset of a 230" B36 flying at Monster Planes USA. Carl Bachhuber...the guy who built the 200" C-124 Globemaster pictured in the Nov '08 issue of Fly RC.

Carl's B36-B gasser is a stunning model. It is a little unfortunate that its high wing loading demands much faster than scale speeds to be stable in flight.

Dag, will you have a chance to share your ideas on weight, structure, materials and methods. Many have theories but from the looks of your project you have some real experience. This build tread is as much of a project as the building of the actual plane. I hope that there has been enough feed back to make this thread worth the effort. I am blown away by the scope, detail and quality of your project. If there were a RC Groups Hall of Fame your B36 should be the charter member. (RC Groups, are you following this thread?)

The forthcoming book referred to in post #5821 (& others) should have that covered!

Carl's plane is nice. Not sure what airfoil he used. His plane on Video looks like a rocket and not scale. If his plane is 98 pounds like advertised then the airfoil is wrong. He should also use flaps. My stall speed clean will be around 19-21, with flaps it should be around 16-17. My wing is 15% bigger than Carl's so mine will land slower. But with his wing he should be stalling around 24 clean, and 18 with flaps, that is if he is at 98 pounds.

The cool thing about going electric is that I will not have anything sticking out of my cowlings.

But remember my plane has not even flown yet, and who knows it might fly like crap. So Carl's plane Rocks.

It would be cool to see them in formation.

If I do write the book (which I feel I will) I will cover that 110%. I am not an expert on building, so say I am crazy, but building light and strong seems to go against 100% of what we learn when we are young. The way I see it, when we were young we just glued the crap out of everything to make sure the glue kept it together. Cars, boats, rockets all are not effected that much by weight like a wing that will stall. If you do not have to worry about vibration for a big gas motor chances are you can build it 30% lighter. 70% of my B-36 is balsa, of that 70% half of that is light economy grade contest balsa, looks like hell, but light. If you took a Goldberg Chipmunk and threw away all the plywood in it and replaced it all with balsa, then make the firewall out of light-ply, and made it electric it would be just fine. Also if you made the spars out of contest balsa with CF even better yet.

But you do trade something with lightness, if you don't know how to land, don't build a light plane.

Have you given any thought to competing at Top Gun? You'd be a smash hit in designer scale.

I'm starting to see this as a reason to convert more models to electric.
And then the clean-up especially when a large glow powered airplane can burn through a gallon of fuel quite fast. That's a lot of gooey mess at the end of the day.

Well its Lunch time.

I fell like I am stuck in the mud up to the axles and moving about an inch an hour. Last night I tested the brake systems with the air regulator. Works perfect, but man what a bunch of plumbing. I will be so thankful when I have these air systems done and can get back to cutting wood. With the main brake air tank at 100PSI, and the regulator set at 35PSI, the brakes work perfect. I get about 2.5 minutes of actuation before the brake pressure is below 35PSI in the main tank. The way most people (I think) set up the brakes is on the down elevator when the stick is more that 15% down the brakes kick in. But I a not sure I like that. If I do much stick flying I may be actuating my brakes while in the air and running my brake pressure down. I may have to revisit my TX and see if I can find an extra channel for this to be activated by a switch. That way I can arm the brakes when needed.

Thanks, DAG
