[QUOTE=thetractorfan;137342]thanks! in the mean time, here is what I am talking about.
in the mean time, I am looking for scrap metal parts. do you know any way to get an R/C hydraulic pump for under 100 dollars? thanks in advance![/QUOTE
Not to insult, you are not going to find a GOOD hydraulic pump/system under a $100 to perform the functions you will need to operate your crane properly. Furthermore, the project you are attempting to undertake is a daunting project. Scrape metal, not quite sure what you mean......best advice, is to save your money and take it one part at a time.
