They're a bit awkward but if you can rest it on a box or such it helps a bit.
A big strong son to lift it for you while you fit the bolts would help a lot more but they're not always available.
My bro held mine in place while I got the 4 bolts in. I tried it on my own but it was just to awkward and heavy. I supported the props and vcu on axle stands get it as high as possible it helps.
