bruder excavator conversions

[edwalsh18]

well, i ordered one up

gonna need some help/info/inspiration on this, first one for me. wanted to build from scratch but i guess i can get my feet wet with a conversion.

i like how this guy used metal for stick/boom/bucket.

i like this guy's way to hide servos, can hardly tell they are there! similar to an idea i had but not quite. also the servos have good strength, i plan on using towerpro mg995 servos

any help will be appreciated. questions and thoughts are more than welcome, not sure what to expect. any bruder conversion veterans with tips, or warnings, etc. help me with any heads ups on what to expect.
thanks in advance!

btw- i am hoping to use this to actually do work. get some digging done in the yard! not just a toy
