Yes you are correct I went back and edited it, I should have caught that misspelling i talked to his every week for the past few months.

Here is a picture I had on the Motor, then I took it over to Bob S. and he finished it up for me, i was getting busy on other things, But not need to finish the plane.

then Bob finished it up for me, He noticed I pinched a bearing so he fixed that and finished assembly.

I went over there Saturday and we timed the MAG, then after a few hand prop turns it kicked then started.

What did you wind up with on the compression ratio..?

Don't let it sit with car gas in it...

[BobSeverance]

If I remember it is like 7.6:1 CR..... or 7.8:1

Thanks to Scott Casler / Hummel Engines for helping me get the magneto timing close... WOW it shocked me when she started up~!!! I had been messing with it for 3-4 days and totally wore my arm out!!!

This engine is going to be a HOSS!!!

It sure sounds good, and looks good on that professional  test stand...  Should be good on low grade mogas... 


We have a supplier that does not add the alky...  they go by Comfuel.  


Southern States also sells non alky mogas around here.

What magneto are you running on that beast?

What magneto are you running on that beast?

Slick 2220, the engine is only getting better and better the more i run it, it has about 4 hrs on it now i think.
I'm also thinking of a way to add a starter on the motor, I have a couple of ideas. anyone else add one already in this setup?

[Flyguyeddy]

Did you do anything about the lag setting?   Ive heard of kickback when starting with a stock 2220

The kickback is not really bad, just once in a while if not thrown through fully.
it is set about 10° BTDC.

Can someone post a picture of the wing end spars it is unclear nif you use a 1/12" wide filler block or two 1/4" pieces, the plans just show two lines with the 1-1/2" dimension. and the supplemental plans shows nothing for this.

I am using the Highmax paper plans as a guide since the Legal Eagle Wing was derived from them. It shows two 1/4" wide strips.

I think you had a question on the wing?  what was that again>?   Looks like it spun into engine comments?

[joecnc2006]

the spar wing tip, how is is actually constructed, I have the caps tapered enough how i want them no more, but the fillers are they how i have them or is it a solid 1-1/2" wide piece.

[PropMan]

The way you have them is correct.
Looking good Joe

One more thing,  I can't tell from the photo if the vertical pieces are 1/2" wide at splice joint of plywood spar face. All others are 1/4" wide

I have not put them in yet, I was thinking about waiting until I place the spar ply Sporting the splice temporary as the epoxy dries, then place the perminate piece centered on the splice I may use a wider piece like 1" just to make sure of a very strong bond. The whole spar will be done with T88, for the ribs I used Tightbond III.
