Jim and Jim,
Another thing you can do to slow or speed up the retriever is change
the gearing ratio of the pulleys being used.
The one I built was just fine for speed, it's the same the TPG uses,
sized from the plans the designer sent me. Sal Peluseo.

*Hi Jim – what I did for my Rahm retriever is get 2 big honking diodes
from the surplus store and put them in series with the power line. This
cuts the voltage down so the retriever runs nice on 12v. There are also
cheaper alternatives, I think on RCGroups there was a discussion about
using a home made resistor to do the same thing. All it was was a
bottle with some lower gauge wire in it filled with water as a heat sink
run inline with the power line.*

it up, there are generally no spares just laying around…*

*Subject:* [RCSE] 6 volt battery for retreiver
Hello All from stormy east coast of florida, I am looking for a model
number and source for a 6 volt battery for our Rham retreiver. It
should have about 50 to 60 amp hours of capacity. This will be a
reasonable sized package - not too grunt heavy! Up to now I have been
using three Trojan T-105 for the winch and retreiver but they are old
and tired. Everyone else around here uses 12 volt winch batteries in
parallel for various reasons. Charging is one of them. So I might
follow suit but I need a smaller retreiver battery since I don't want to
lug a T105 if not required! 12 volts makes the retreiver run too fast.
The new fully automatic retreivers work very well but the club budget
will not stand that this year. Any ideas? Somebody has to make a
reasonable sized 6 volt battery larger than the 20 AH things for
motorcycles. Thanks, Jim
