Changed the motor for a 80mm 2000kv Medusa motor and mounted it higher this time.It needed a longer flex shaft.
Fitted the 2 lipo packs in the centre this time,which were easier to fix down.
Ran well this afto with a detongued X645 prop.
After 6 mins the packs only took 3250mah! which is an average draw of only 35amps.
It has gone a bit noisy which i think is resonace from the Shockwave strut.I will have to source some better bearings for the 3/16 stubshaft.
last run of the day was about 12 mins.Lipos/motor come back barely warm.
Bit of video with jack,my son,racing a Dr Psycho mono2 boat again on 4S lipo.
Not one drop of water inside the hull[8D]
