Im only a "kid" in building cats., and would like making it possible to go a bit backwards, in case im getting to near the cliff, or in moulded water.

Do you have any suggestion about this.

Other boats like Tugs and cruisers, its no matter to make the boats going backwards (know from Smit Rotterdam and the old Admiral from Billings/DMI) on which i also are doing some buildings.

The issue is more to be sure the flexshaft (motorend) doesnt vent loose on backwards.

Is it possible to set in a STOP-bearing in front of the shafttube by the motorcoupling, like in classic modelboats?

I allready have the T180s. for my very first cat, and barely cant wait for the r2hobbies-hull to arrive.

Bought a plate of 2 mm carbon, to make a light motormounting; and 4 packs of batteries too (2x3s)

In order to get the hull more racing-suitable, i have ordered some real carbonsheet for the inner-hull, just like Keith Bradley did with the Explorer.
