Hey guys, my older son had a mishap with my little guys 250ex and broke the right side a arms. I was reading through that thread and others for using the 400ex arms. It looks like the lower arms are a direct fit to the chassis and just are about 2 inches longer. Now in Sykos thread he said that the 400ex uppers were a little too wide but also mounted two inches outward compared to where the 250ex uppers mounted. So my question is does anyone know how much longer if they are at all the 400 upper arms vs the 250ex arms? I’m was just thinking if they were close to the same I could make some brackets like he did but using the 250ex uppers with the 400 lowers. Lmk if I’m crazy but it didn’t seem too far fetched after taking my sons quad apart and doing some measuring.

Thanks
Ryan
