You can vary the speed of the retract by using the speed controller but in practice I found that a small 2 cell Lipo was fine for power. They now do both brushless or brushed so the choice is yours. With the retracts I used M3 to 4mm pipe Festo fittings where space was a bit tight. The retracts will need to be taken apart to drill and tap them for the Festos and make sure they are clean of any swarf.
