Thanks AGR413 and MMallory for the replies. I did plan on using locktite on all of the metal bolts.

I replaced the front bolts on the booms with a 4m x 50mm hex bolt and a 1/8 x 3/4 fender washers. I had to use the long bolt from the bottom of the wing all the way through because the Monday built side of the plane, the bolt was going all the way through and coming out the top of the boom. The Friday side was working as designed as the bolt did not go all the way through like it other side did but I made it the same for both side for cosmetic purposes. I did not want to do the surgery on the booms to get the blind nuts out. I used the fender washers to make sure the compression from tightening the bolts was spread over a larger area and to make sure the hole in the wing was covered.

For the rear bolts I used 4m x 30mm socket cap bolts and fender washers. I used the fender wahsers here for cosmetic reasons to match the other two.

I got them all at Lowes. Cost me about $8 for everything but I did buy more than I really needed. Should run you less than $5 if you buy only what you need.


You can also do what this guy did. Drill out the blind nuts and runs a bolt all the way through and a nut on the bottom. [link=http://www.rcuniverse.com/forum/fb.asp?m=4920007]click here.[/link]. You would need about a 2 inch bolt for the front.
