HI Guys,
I have an electric powered ML Boatworks 8255 1/8th scale hydroplane powered by a TP 4070 880kv motor on 10s1p lipos and am having problems with the hull. The driveline is offset to the right 1/4 of an inch looking from the back and the rudder (sport 40 square rudder) has been tried both on the right side of the hull and now the left side. Driveline was offset due to turn fin and rudder being on same side of boat. I have used 447/3, x450/2, x452/2 props without any success. The boat now has a 1/2 inch by 1/2 inch airdam under the hull. Strut is a flat bottom and set 26mm below bottom of hull and flat. ( no negative or positive angle.)
The problem is the boat is very unsettled and basically flighty even in smooth water conditions. If you drive it flat out it will blow over down the straight away, even with the batteries as far forward as possible, however if it hits another boats wash and gets airborne it always lands front first which is telling me there is too much weight forward but I need the weight there as it blows over down the straight.
Questions:
Where should the C of G be for this hull?
How do you get the hull to sit level left to right sponson wise with 10s packs jammed 1.5 inches off centre to the right due to the offset tub?
Rudder best on left or right?
Strut depth?
Is there anyone racing these successfully in electric form?
All help is greatly appreciated.
Thanks
Trev
