Hi , iv'e got the arpro p1 and hink it's a good boat for the money and with suitable mods goes very well !. Just puzzled as to how you say it runs a flex shaft as mine has solid 4mm shaft and would recommend anyone to swop that shaft to stainless steel as original is a soft metal and starts to round off easilly at motor end . The setup I've got is standard motor on 3s lipo running octura x443 or x642 props . X642 gives the best drive with no heat issues that I've come across. The leopard 28 series fit straight in with no problems but do remember that high kv motors do pull a lot of amps with large props .yup destroyed my esc the hard way though not finding that the cooling hose had slipped off the rudder might have had a part in it too . Leopard 2845/4420kv worked well on 2s but too fast on 3s for the pond I use !upgrade esc if thinking of upgradeing motor !
My sword has basically the same soft metal driveshaft as your boat,but has a flex saft 3.18mm which is connected to the motor end which fits in the coupler... I can't find replacement driveshafts any wear for this boat...On mine the front and rear 4mm sizeends has a nice sealed bearing...I installed a plastic tube over theflex portionbetween coupler and bearing to keep front bearing from popping out...The arpro is samesize as my supervee,and it seems to be about to handle around 40- 50 mph without blowing over,also like the fact that it uses1 3cell like my sword,so it seems to be the next boat i will buy once i get this sword setup to run perfect...
