I finally have sorted out the leaks and the drive system in my home build 36 inch rigger I styled it on the KEPS plans I downloaded for free on this forum and I just changed the construction from plywood to carbon fibre and the sponsons are solid balsa with 1mm fibreglass ride plates.It is lighter and stronger and has less flex than the KEPS but it is a bit bigger, I wanted more room so I made it a bit bigger in some places and a bit pointier at the nose to cut the air nicely. It has a TP40 60 6D 1650 KV running a 50 /100 C HRB 5000 mah and a 200 amp ZTW Seal esc and a Andy Brown sharpened and detonated balanced 47 mm Octura with 1.4 pitch with a .78 piano wire drive Shaft.
I am only getting 54 mph The strut is level when I put a straight edge from the rear shoes to the sponson ride plate tips. I tried a 31/6 flex at first and it was noisy and slower.
The run time is hard to tell from such few trouble free runs but I?m guessing 4 mins I tried the amp meter on a run and it said max 2100 watts and 85 amps nothing gets over 105 degrees except the battery it vet around 120 after a 4 minute run. The run this morning was 2.5 kilometres and went down to 22.5 volts about 4 mins run time the balance is even on the batteries but I had to delete the low voltage cut out.
Any thoughts ?
