so whats the deal with these triple prop (3 fins) things? Do they make a diff in performance versus the standard probs with just 2 fins? does it create more thrust? Would you recommend it on a trainer?
Getting back to Mchwindchimes original question -- if it turns your crank to have one, by all means do so. On a trainer it doesn't matter -- enjoy yourself. However, it will cost you in various ways.
Greater weight
Greater cost
Poorer performance than a suitable comparitive 2-blade.
For the same prop manufacturer, same construction materials & same blade geometry as the appropriate 2-blade, your engine will make the same power, but it will produce less usefull work with the 3-blade prop..
