From my old model rocketry experience, while you want the CG ahead of the CP, you don't want it *too* far ahead or else the rocket will tip into cross-air currents (e.g., wind) excessively. The rule of thumb was CG ahead of CP by the diameter of the rocket, Anyway, love your channel and content. Keep it up!!

@@alpha_pixel_ Mmm, that's a personal opinion, but I kind of thing it is much more complex than this. That's what could be called an 'interface vehicle'. Meaning that traveling at the same time in interaction with several (two) types of elements (here fluids, liquid and air). Which one has the upper hand? As in F1, aerodynamics impact parts which are also in contact with the ground. But the opposite is also true. That would be the same for a sailing boat, that could be seen a a blend between a wing and a boat, the with the added complexity which is to deal with other interactions, as when the wind blows, the waves tend to be higher, meaning that the scenario changes as the 'envelope' does, and the design should accomodate for these changes. Not an easy task! Best regards!

You could try making the planing surfaces tapered so that they become thinner as the boat lifts out of the water so that it is less jumpy because it appears your getting an oscillation that increases until it torpedos

Explore boats on underwater wings. There was quite lot of those used in river navigation of USSR. It also has 3 points of contact with water but under water. It gives better stability because there is no surface that causes transients while boat touching and detouching it.

@BaddaBigBoom 2 года назад

Speaking of Rapier, I'm glad to see that a new company has started making similar motors. Rapier could no longer export (as of 2010) as a result of the Czech authorities inappropriately touching the rules and reclassifying them as "fireworks".

@tuomassyrjaniemi 2 года назад

Bigger boat and even bigger rocketengine! Maybe you should include there little bit electronics and make a gyro stabilization system in all 3 axis. A Goal would be to get straight line and more speed. I also recommend to make front ”skis” bottom v-shaped to make them less responsive to little waves.

Makes you think about those old speed boat world record attempts that often resulted in loss of life. Water is definitely fighting against you here, and even with perfect aim for some point, the waves will alter the course. You'd need to have steering but how in the world can steer from the beach something that fast and that sensitive to small waves?

@ToninFightsEntropy 2 года назад

@Berkana 2 года назад

For this hydroplane design, you may be able to get more reliable onset of planing behavior by putting two thin cheek pieces on the wedges so any trapped air can't escape out the sides. The cheeks or side-walls would basically force any air in front of the sponson wedge to go under it; the only water drag you would incur would be the two thin side walls slicing through the water. Same with the wedge under the boat itself; sidewalls may help force any air in front of the wedge to go under the body, causing the onset of planing to happen more reliably. Could you try that and see if putting sidewalls on the wedges improves the onset of planing? I'm curious to see if that works.

@FarmerFpv 2 года назад

With an EDF it gets water spay on the fan and most of the time the fan implodes or it goes super slow due to water hitting the blades. You would have to work out a way to prevent water from hitting the fan blades which isn't easy on a small scale. Best of luck. Just have fun.

@AndyDeMontana 2 года назад

Our racing riggers use two CF tubes, fore and aft. This prevents them from twisting, which is what appeared to happen in the first run when it avoided the retrieve boat. That would also keep it running in irregular circles as it did. Also, cg is important. It should balance slightly behind the rear edge of the front sponsons. On a 24 inch boat about 1 inch back. And a fixed rudder at the rear will help with tracking also. Keep at it!

@ciciro6 2 года назад

Your stability problems are the result of launching the boat with the current of the water perpendicular to the boats center line. Those tiny ripples are large to that tiny boat. So it causes a rolling motion until one sponson is completely out of the water. The opposite sponson is levered down into the water, increasing drag on one side. Thus slowing that side and inducing yawing motion. The solution for the tiny boats would be to launch the boat parallel to the current. So, yourself on a boat anchored out in the middle, I would suggest launching into the current so the tiny boats would float back toward you.
