Hi Darin,
Your build seems well thought out, and nice and neat.
Something I have changed in the instructions was to NOT use a tap in the nozzle and cage, and let the screws tap themselves. I think rather than let people find the right drill, I will drill all holes in the units so as so people do not have to be so exact in these areas. May even sell these as already assembled for and extra $15, so people do not need to worry about them.
I have also since changed the instructions so you swap the cage around so the trim input is on the L/H side, so you have enough room for the servos and transom seals.
I read earlier on in this thread that some people experienced hopping, This is due to a number of factors, Too small a hull and the C of G is not set around 35%- this was found on hulls shorter than 650mm long, and there is insufficient length in the delta or ride pad.
The main thing people have is trying to compare this unit with a KMB or Graupner, they are not a MIXED flow Unit, where it differs as these unit have about twice as much suction, as such will suck the back of the hull down harder, if the delta isn't long enough and have a constant transition all the way, you will experience what happens to a spoon if you pass water over it ( porposing) .
By the looks of it you have your Cof G set about right , you will have no problems pushing this unit to 4S , just make sure you keep the grease up to the shaft before you take it out for a run, the reason for keeping the hex part outside the boat was for maintenance .
I am now following this thread with interest, keep up the great work mate.
Regards Mick
