maiden run
Maiden run of the boat was on saturday with really beautiful weather. On Thursday/Friday we did just really minor work like soldering antispark resistors or making a wooden boat stand. But Wednesday night it would have been already possible to make a test run.
Here a picture of Chris at the maiden of his new HPR C5009:
I set the boat up and adjustments of the drives/CG from my experience and knowledge with a set of Octura X442's. With these the boat performed already quite amazing with a top speed of 89mph. Beside this great performancy hardly any temperature from the components, especially the motors were almost cold although it had 35°C outside. Here a video of that run:
For the last try of the day I mounted a pair of X447 Andy Brown and mounted my Holux GPS on the outside of the hull. Chris had a great respect so he took the camera and I had to drive the boat for max. performance.
So everything was connected and checked before we taped the hull. I put the CG a little forward, didn't change something on the trims. But I really underestimate the 4-Pole TP motors with their low IR. They seem to have a really sharp throttle response in combination of the T180 ESC's. Timing was also just a mild 15°. But the acceleration simply was so high that the boat made a wheelie and flipped. I can definitely say it was not a flip due to high speed, also checked the complete log of th Holux on my notebook and top speed was just 79mph.
Here a video of that try:
So we simply couldn't stop with this result and go home. We rescued the boat and checked everything. Beside some little water which came through the linkages everything was fine. Boat was dried and the batteries charged while we put some grease into the linkages.
For the last try of the day I was again responsible for driving and Chris took the camera. Meanwhile I also moved the CG forward from experience to compensate the higher speeds. And this time it was almost perfect and I could really give WOT resulting in this:
On the GPS it noted a straight 101mph (also checked that at home on my notebook, was 161.6km/h). So a 100mph run on its maiden running day, not too bad for the fast build and the really cheap components.
Now Chris is really happy with his new toy and enjoys running it:
Have a nice day,
Manuel
Demnächst gibts dann weitere Fahrberichte und Ergebnisse!
