Agreed on both counts.
But on a boat like this the CofG would be too far forward when at full flight because only a fraction of the hull would be in the water and the 'moment arm' would be measured from the point of applied force, ie. the propeller. Surely if you could get it right at the design stage, it could eliminate the necessity of trim-tabs! That a point, should the CofG measurement also include the trim-tabs?!!!
Am I being augmentative? Sorry, I live with a teenage son... that obviously knows EVERYTHING!
Hi mart my boats are designed not to run trim tabs there designed to be driven on the egde thats the point of tunnels,having the cg where it is at this starting will tell me if it needs to be moved back or forward.And another thing is tunnels/cats/hydros do not run trim tabs any,and any well set up mono does not need them either and this is all controlled by the cg placement,if the nose is light while running move the CG forward a little if its running wet move it back till you find that sweet planeing altitude and maximum speeds of what the electronics will deliver.
When setting up my boats the outboard and the strut are both adjustable,how ever i only ever adjust these if the efficient cg cannot be altered any more,the angle of the prop/strut/outboard is set to neutral position.

Why not have the "cog" adjustable "to a small degree" by the individual? say by making the battery position/locator moveable?
if this is to be a "club racing boat" this could be one of few "variables" for the individual racer to adjust, within the rules so to speak. making everything 100% now leaves no option for the individual, but getting the boat 99% allows a little bit of "edge" for those wanting perfection.
I'm still a little wary of seeing the "result" of 6 or 8 of these in the water in one go, racing around a circuit we have planned, but only time will tell I suppose.
if the boat is going for "retail", then yes, by all means it needs to be 100% "RFT"
Hey bud the cg is not a 100%,it will be all down to whats being run,yes the motors,esc,hardware will be the same,the batts will make alot of difference,iv got a 2s,3000mah batts made by 1 company,yet the same size batt made by another company is slightly heavier.
Another question is why so wary,it will be no different than having 6-8 of the other boats going round just a little faster,yes there will be accidents its racing an somtimes just unavoidable,Just like driving down the road and some1 hits,its the same thing.
This will be a fun class to participate in if the members are all in agree.
Only time and testing will reveal how this will unfold,and im sure the other members will enjoy it too
