A little progress XL H-58

Nothing like an odd fire engine on an odd number of cylinders...

Not to mention it pulls like a locomotive..and.. it's fun to operate. After all, that is why we do this stuff.

My old friend and Lindy award builder Mike a few days ago..
Unedited cell phone video:

When I rigged Bullet, I just used my phone with an angle app to get the washout at the tip. She's a little right wing heavy, so I thought I'd have a look. Mike, who is flying Bullet in the above video came today and brought his fancy high zoot digital level. .1 degree increments. (!) On a normal airplane, I would just turn the left rod end a turn or two to add a little washout on the left wing. Naturally, what you build is what you get on the Legal Eagle, so I was fully prepared to make a new rear strut fitting.
He said, "Let's see where you are" and started measuring every thing. "Hmmm, looks to me that if you put the bolts back in that rear strut fitting it's going to be pretty close." Did that. "Bingo. Less than a tenth of a degree difference in angle of attack, dihedral, and washout." (!) "That phone app must have been pretty accurate." Yeah, but not that accurate..
I've mentioned before that I would rather be lucky than good..  
We decided that the right wing heaviness might be because I put the tank in the right wing. Do you guys with the tank in the left wing have some left wing heaviness? Inquiring minds and all that..

Which tubing you used for wing struts? I am from India 6061t6 tubing is not available here. 1000series aluminum and 4130 steel tubing available please also mention the dimension of the tubing which i can use according to you like OD, ID and thickness..

Welcome to the forum, Devendra. This is a subject that I hesitate to make a recommendation on. Certainly I would avoid the 1100 series aluminum.
A quick internet search shows that tensile strength of 6061T6 is 310 Mpa while 4130 is 1110 Mpa.
You will have to make your own determination as to what size 4130 to use. Sorry, I can't be more specific..

Thank you for this..i hade an conversion with someone here he said 6063 is available..what is your thought on 6063 for struts. One more interesting thing which I have seen in your post the tailwheel it is different from the plans..it looks that you simplified the Tailwheel by doing this..

Yes, it gets rid of the weight of a tailwheel spring and casting or weldment.
I, personally, would be comfortable with 1 1/8" diameter X .035" wall 4130, but it is *your* life on the line. Obviously, I can't make any recommendation for legal reasons if nothing else.
Here is some engineering info on aluminum..

Greetings, Earthlings..

Nothing like a hot summer evening in an open cockpit.

[Chuck in Indiana]

Gaa! Going out for a dawn patrol, hit the starter button and it kicked back.

Oh, well. I needed something to do..

Does that mean we should turn the engine over by hand two or three blades before starting?

[Chuck in Indiana]

My drill is sump the gas, turn on the fuel selector, pull the plugs from the exhaust stacks and pull it through 5 blades.
Then, preflight. Did that.
Back in the day, the way to start the Warner on the Great Lakes was to turn on the mags as the engine was cranking. Maybe I should have thought of that? Dunno. I'm not terribly happy right now, but I'll get over it. 

[Kamcoman77]

I feel for you. Hopefully parts are readily available to repair.

[Chuck in Indiana]

Tomorrow will tell the tale.

Better it broke there than the crankcase...
Does it start @ 0 BTDC?  Maybe a timing malfunction.
