RC4WD 4200XL models and nomenclature?

[schmoking]

vers. 1.5 is suposed to have 4 valves... the 4th valve is mixed in on the tx so it closes when you use the boom`s and bucket, and open when youre not so the oil can circulate back into the tank.
version 1 only had three valves, that caused some leaking issues with all the pressure on closed valves.

this is the vers. 1.5 valveblock... http://store.rc4wd.com/Hydraulic-Val...15_p_1832.html

i have a diffrent pump motor in mine, but if i remember right i think i heard others say they have it set to 23% or 24%.
