had two testing sessions, I had TWO eagle tree data loggers on board, one on each motor, it was a good opportunity to see how much the motors differ, I have my own set of Eagle tree data logger, lcd screen readout, gps module and rev counter, and will be selling Peter Henshaws duplicate set so it was an opportunity to test it and make sure it works, it was brand new in sealed bags, but worth taking the iopportunity to use it.
Well, my dilemma about counter rotaing props ended, for now anyway, that picture earlier of beautiful shiney props, one is now at the bottom of Gautby lake in Birkenhead
Not concentrating 100%, didnt obviously tighten it up as tight as it was yesterday, and as it was the counter rotator, it fell off
Luckily I already had some data,
Propshop 3 blade cleaver as per pic, 20.83mph with 37amps, so quite efficient, well at least it was
Graupner two blade 50mm "x" props, same rotation 21.64mph with amp draw of 37.95. Troubel is, over 20mph this hull really is struggling, and you are holding on tight, not like my Huntsman that thrives on bumpy water and speed, this narrow shallow hull does not like speeding over its own wake in a big figure of eight
, but its not really supposed to be going 21mph is it!
I also had a set of 3 blade 40mm cleavers, counter rotating, that had been 4mm, so spent quite a while this mopring turning them to 5mm to fit this boat. Suprisingly, they just dont let the motors spin up, 4400rpm down on the "x" props, but planes much better as its 18.76mph, and quieter.
So there it is, I think the sub 20mph is better, boat looks better, and I was on a very big lake, on a usual sized model boat lake it will probably look way faster, got to find someone to video it now
jumble of wires with data logers x2 and the display screens
