Hi Mark,
Its BG again. in lane 1.
On your mark.--- Video does not do justice to your boat. Kind of underexposed or was the weather brewing for a storm ? Congratulation for good video clip of the test run.
Get Setttt! ----From my observation of the run on the clip. First run with cowling attached, looks promising. Second run without cowling better as the craft float a little more and moving a little faster. It tells me cowling is a little heavy or the aerodynamic on the cowling presses down on the rear half of the craft lowering the prop at high speed and hence less rpm and a tad slower speed. Third test also without the cowling and a kick back trim adjustment made. End result - not as good as the second test.
Gooooo ! ---- .Noted that when you get towards the turn pin , you slowed down a tad which allows the craft to settle in a little allowing most part of the right sponson to become the turn fin . Hitting the apex of the turn , you gassed the power gently and you exit the turn flat out . Craft look well under control and thats safe for racing.
Another time you came in to the pin on the right pretty fast , craft did not settle in and you gas it hard again at apex for the exit and saw, the craft got out of shape a little in the turn and it also affect the straight run that followed.
For oval course racing, the craft would be okay given a close control at the turns . In a tight circuit like ours at home with five turn pins to form a shallow M course, this craft won't last that many lap. A 150 and a 120 degree turn in choppy waters at some speed likely to cause a barrel roll.
Mark, this is just my observation and to conlude, IMHO, you should try and get the sponson to grip more by lessening the centre pod depth especially towards the transom
Hope this is of some help mate. Keep up the good effort. Latiff
