choice of excavator i need help

[dus]

Hi Percy, Thanks for the reply,
I know the hobby engine excavators can have the slipper clutches glued to make them lift a little more weight but I'm not sure as to how much more,
The top race excavator is the smallest of the bunch, the HuiNa is about the cheapest but I'm not sure if they can have there slipper clutches glues as well and I'm guessing they all have pretty much the same set up as far as the inners go it might be worth a look at them all in turn and see if there's any real difference before and after any gluing mods that can be done.
you could probably strip out all the workings and use good quality servos but if they had to go on the outside of the excavators it wouldn't look right to me
So I'm still unsure about the whole thing
I would love to have one that has hydraulics but way out of my price range
