@eelcohoogendoorn8044 10 месяцев назад

Nice, the stability of the feedback loop on this one has indeed converged to something really satisfying. Another nice thing about the hovercraft motors is that you could program some differential-thrust-roll-control into those; seems roll stability is one of the limiting factors now and that might really help it shine in gustier conditions.

If you watch that last demolition video from Testflight where Peter Stropol made the many, many winged plane that was insanely stable.

@craigcolavito5606 10 месяцев назад

in Formula 1 motor racing, the aero designers frequently will induce vortices at the front wing which serve to "seal off" the floor of the car from outside airflows, efectively making artificial invisible skirts. I'm not sure if this would work on the R.C. Scale, but it might be an interesting way to make a skirtless hovercraft. this MAY end up making negative lift however, which is obviously optimal in a race car, but not for a hovercraft of Ground Effect vehicle. Nice 124 Abarth Sebastian!

@blahorgaslisk7763 10 месяцев назад

If you want to see a few takes on DIY water jet surf boards you can look at RCLifeOn and Hacksmith Industries. Both have videos on the construction and build of electric surfboards. RCLifeOn also tried making a Hydrofoil surfboard, but with very limited success. The RCLifeOn surfboard totalled about $3K in parts and seems to have reached about the same speed as surfboard in this video. I can't remember if he ever talked about the battery time though. But being DIY it's limited by budget and how much weight you can add. Don't remember much at all about the Hacksmith version. But their production is always polished so entertaining to watch. And they too have given the hydrofoil idea a spin. And they had a little better results.

@atatoraman9257 10 месяцев назад

@rctestflight the flat/kf airfoil that you have is not great to get high pressure under the wing because it relies on the fact that the flow is constricted at the back with the elevons. You might be losing pressure that way. Try a more aggressive airfoil with some camber and a lot of thickness if possible!

@thomas316 9 месяцев назад

0:55 Instead of being circular, vortices in proximity to the ground become elliptical as the airflow is pushed outwards. This causes the effective aspect ratio of the wing to become greater than the geometric aspect ratio and reduces induced drag. Both lift (and airspeed for any given engine power setting) are increased. Consequently high cord wings are favoured in ground effect over high span wings for ground effect vehicles.

Rule #1 is the 70% rule. All cruise speeds should be no greater than 75% max, to conserve parts and fuel. I admit, however, that's old screw powered naval ship lore. Newer designs might require different drive numbers.

@DetroitMicroSound 10 месяцев назад

@lady_draguliana784 10 месяцев назад

low-alt option: light, thin rod with a hydrodynamic floater on the tip. attach it on a hinge to the nose so it trails under the fuselage. connect the midpoint of the rod via cable to a cable-potentiometer in the fuselage. use this, with some trig, to measure the altitude off the water in a more direct way. (similar to the mechanism used in a toilet tank) the experimentation would be to see how small and short you could make the dipstick. if it's really long, it could be measuring the altitude BEHIND the vessel, so a shorter, more vertical one would be better for measuring, but would also put more force on the stick, meaning it'd have to be larger to survive. 🤔

I'd be interested to see a similar vehicle using 4 drone motors controlled by a flight controller keeping it stable. Basically a drone but with wings so that the quad motors generate ground effect and stabilize rather than full flight. That or I'd love to see a "hover craft" that uses 4 quad motors and a flight controller to control its altitude based on sonar data. It'd would basically be a low flying quad at that point but the idea of it staying at a fixed low altitude above the surface automatically would be really cool. Not efficient at all but something about staying a foot or so above the surface like there's a force field feels so futuristic and cool to see. Especially if it can maintain that distance over uneven land.
