GRX SAW RiGGER

Thanks guys..I'm waiting for the videomaker edit the videos and send them to me...soon as they really help me to figured out how the boat handles those high speeds especially at slow motion! Interesting info Martin that makes me wonder that probably with small motors a significant difference can be observed with higher discharges!Next weekend I will get a try to the A-spec batts and let's see what happens.Thanks Gill

... im suprised i saw thes increases on such small boats & motors as i would of thought the 45c Nano would of been more than capable of delivering all the power such small motors would of been asking for & going to 60c wouldnt have had such an increase that i saw....

it should not be such a surprise since LiPo sellers have no real standard for rating the "C" rating. Many are clearly over-rated by the seller, which your testing indicates. Even among top-quality brands I see little difference between 45C and 65C packs, even pulling over 300 amps.

Fluid i understand & agree with what your saying about inflated c ratings with certain manufacturers, even allowing for this i would of thought i wouldnt of seen these increases on small 380 size motors as their only rated around 40a.

Grimracer posted that there is a guy at Aquacraft that daily spend hours and hours testing all sort of lipo batts and the best performance obtained was at 40C.If I'm not mistaken Chris Harris got those faboulus speeds using 45C so...better off be in the safe side of the 45C and save some bucks.I will test the only two 65C packs I have with a Leopard 4082 2000kv and see if there a gain in performance.Gill

here the brave survivor of the marathon of tests.Three boats built with the same care & attention but for any unknown reason this is the best of the trio!Gill

very shortly I will be putting together a video camera mounted on a headband (they make such small cameras now ) and will be getting into video editing to make professional videos.

The Gopro hero2 is what I use to make good vídeos on my surfboard but never tried it on a model.

I would be video-taping from shore so i dont need a camera man. you could mount the go-pro on your head for hands free video taping.

Great results Gil,

Those numbers are right up there with Joerg's, Chris' and my numbers for a Q hydro. I will also admit I have seen no difference between the 45c and 65c packs. I have run both back to back with the same set-up and speeds were within 2-3 mph. The battery temp had more of an affect than the C rating.

I will second the MBP couplers, well worth the money. I am hoping one I have ordered makes it here in time for our SAW this weekend, but I think the customs office likes it too.

Looking forward to the video.
