Do I need Turn Fins & Trim Tabs?

[BigJohnnyNC]

I have ordered the forum members recommended power setup for my Graupner Electro Vee! Do I need to also install Trim Tabs & Turn Fins?

If so what size?
I’m a Noob at boats!

Who can answer ?

Run your boat without those tuning parts first.

The ElectroVee was a vacuum-formed hull without sharp chines or strakes. As such it tended to slide a bit in turns. That wasn’t much of a problem with the 1990s power setup it was designed for, but with today’s power maybe not so good. What power combo is the OP using - motor, ESC, voltage and prop?
