How do you go about straightening an Al boom? I have a duotone boom that got bent on one arm when I got catapulted. I'd like to have it available at least as a spare
I had a crash from breaking a mast in a gust which somehow also resulted in a bent boom. To straighten it, my dad and I had to stand on either end of the boom to get it close to straight and then we hammered a splint piece (around 25 cm that we cut from a snapped boom backend) into the area of the bend so it went around 10cm past it, and it is now as stiff if not stiffer than my dads newer one and I have had no problems with using it apart from looking slightly odd.
This is what it looked like before being straightened
