Hi All, Have a couple of ?? re a dragon shark 2 mono 1 fast electric, 1st could apply to any electric
nitro or petrol boat with a flexishaft.
1, Does a flexishaft tend to shorten when its revolving at high speed ? as I am trying to judge how much gap there should be between the dog drive, thrust washer etc and end of shaft tube.
Boat has a single quite long turn fin on the right hand side, which at the moment I have set the same as
the rudder approx 90 degrees to the transom looking side on, fin is angled inwards about approx 5 degrees looking from the rear of the boat see enc pic, Gave the boat 1 run on a 2s lipo, boat is very fast and seems to turn right ok, backing off the throttle a I can turn left in a wider turn I have not tried a
tight left turn. as know these boats are ment to turn right only, thats about sum of my knowledge as
surface drives go's.
Before I put the 3s lipo in it and after a search of the internet on rc boat turn fins, seems they angle
the fin everwhere inwards, outwards, also backwards so there is not so much of it in the water, my 2nd ? is where and what angle should the fin be set at ?
As along with my scale boats I mainly do fsrv, so not got a clue about these flexishaft offset rudder
turn one way only little beasties, any help would be much appreciated.
