Ok I find this very strange but in China, you would think the rules would be extremely strict especially air space on sensitive areas over there. However they will let you fly drones, rc planes and homemade rockets practically anywhere, so basically you can fly drones over the Great Wall or at any National Parks, as long as it's doesnt harm anyone, wildlife, or for anti government purposes. Whereas in the US and Europe the rules to fly rc planes, drones and rockets are so strict, try flying a drone over the any National Parks or a Canyon you'll be arrested and fined. Practically cant have fun anywhere nowadays without registering your hobby drones and planes, let alone launching random rocket at a football stadium without the FAA freaking out, or bad enough some bystander calling a cop on you for spying. Then you have countless of things to adhere to from FAA, EASA etc.

@@zero00tolerance That's the difference between a government that cares about safety and one that does not. The FAA is a highly regulated organization with shits tons of standards defined for what you can and can't do because people can and will do dumb shit. It's why US airspace is the safest airspace in the world with an astronomically low accident rate. Even the Chinese government themselves dump rocket boosters with toxic hyperbolic fuels over their own small villages without a care in the world.

Yeah especially in China. I’m surprised he’s even gotten this far in making rockets without the government shutting him down, he’s got to be a proper aerospace engineer or student not just a random hobbyist even if he’s a Han-Chinese guy

for anyone wondering, duck-layout should actually be canard-layout. Canard is the French word for duck, and in Chinese this is literally translated as "duck-layout control"

I dont know.. he was meant to be the cameraman, not uselessly spin around the subjects. Everyone can ride a bike, but do you have the control to be able to ride a bike whilst filming someone else racing around? It felt like this guy was just going for a normal flight instead of letting his skill speak for itself by using it to take good footage. Eg after the parachute deployment he could have located those tennis courts and kept it behind-shot, to keep the rocket in view silhouetted. There's very little actual clear footage focussed on the rocket from this pilot.

Most normal Estes model rockets will perform as well without any Electronics. Why did you believe you needed electronics for such a low-altitude flight? You might have said that but I don't speak the language in the writing in the video so I'm not sure what the point of all this was.

The rocket in question uses a parallel design with multiple engines. One of the challenges of this design lies in the need for highly coordinated ignition among these engines. Even a slight lack of synchronization in ignition or minor inconsistencies in the thrust curve can have a serious impact on the rocket's attitude control. This is because such discrepancies might lead to an imbalance in the thrust produced by the engines, thereby causing the rocket's flight direction to deviate. In addition, during the initial stages of flight when the rocket's speed is relatively low, the stabilizing torque generated by the tail fins is quite limited. The stabilizing effect of the tail fins is directly related to the rocket's speed - the faster the flight, the greater the stabilizing torque produced by the fins. The most critical point to understand is that the stabilizing role of the tail fins primarily pertains to angle of attack adjustments; they do not directly control the rocket's attitude. When the rocket is disturbed, causing its axial direction to deviate from its velocity direction and thus generating a non-zero angle of attack, the tail fins will produce a stabilizing torque to counteract this disturbance, aligning the rocket's axial direction with its velocity direction once again. However, while the tail fins can help the rocket regain its velocity direction, they cannot restore the rocket to its precise attitude before the disturbance. This highlights the limitations of tail fin stability.

@@lshang882 I have flown few rockets with three paralleled C engines. With a guide rod, they go pretty straight up. In other words, I have not encountered serious problems with those rockets using parallel ignitor connection. Could you share us with details of challenges you encountered? Is it a general problem when you DIY engines?
