Delta Force 35" trim tabs

[siberianhusky]

inboard tabs will control the straight line ride, outboard the ride in the turns, big boat you could use both, I'd try shifting the CG, stinger angle, different lift prop.
I use trim tabs as a last resort, always try to set up a boat without them first.
As the speed goes up you may find shifting the cg will smooth it out. Even the rudder causes lift at speed. Try changing the rudder castor.
The faster the boat goes the harder it is to get it trimmed out at speed. The last few mph is the hardest. Some guys spend serious time and $s trying to get the last mile or two out of a SAW setup.
AT high speeds aerodynamics and hydrodynamics are working on the boat.

Disar I run them inboard and outboard on my DF 33 and I have two of them and it works for me.

oh yes, this is another issue, inboard or outboard?

They look to be placed way to far inboard.................

I have trim tabs in my DF35" but I think they are a bit small. Upto 75klm/hr (46 m/hr) it runs stable but over that speed I have movement pt-stbd like rolling and wondering if bigger trim tabs will be better.
DF35" owners, what trim tabs you have? Thanks
