Anyone tried using GPRS modules for long distance Telemetry? Could a module like this work

Reviving Excellence: The CC3D Revolution Flight Controller After an exhaustive assessment of available flight controllers from 2013 onwards, our team is thrilled to announce the re-launch of the CC3D Revolution flight controllers. Despite its current unavailability and sold-out status, the...

I could simply just try the 360 servos on the flight controller. I don't have this data from any flight controller as to what signal is actually sent out from the flight controller to the ESC which in turn controls the brushless motor. Actually I am using a flight controller in a submarine...

Just need to know whether it would be fine to connect 360 Rotation Servos in place of brushless motors and ESCs on a Flight controller

Also, my purpose for this post was simply to get some help in connecting 6 servos to a pixhawk (which thankfully was received from another forum). I have shared this post as a pdf schematic of a pixhawk connected to 6 servos, which was not necessary at all, just in good faith for those who are...

Unfortunately, we use propriety fuel. It is manufactured by our subsidiary here in South Africa. You will have to design your own jet engine in order to use it. Do your homework and try and manufacture your own fuel and jet engine. Ours is in prototype stage currently and so far so good. It...

Answers were given according to previous post about latency etc. Regarding weight, pressure and size, I do not regard that as important. There are numerous cold fuels out there and their specific gravity varies. Tanks are usually pvc and lightweight. A liter tank is around 190g. Pressure is not...

The question of latency does not exist as the expansion occurs is in microseconds. Feed rate of the fuel into the expansion gas chambers is controlled by the servos. Servos function: 20RPM for startup. Full thrust = 200rpm Hover is around 80RPM. It is obvious that it would be absolutely...

From Wikipedia, the free encyclopedia A cold gas thruster (or a cold gas propulsion system) is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust. As opposed to traditional rocket engines, a cold gas thruster does not house any combustion...

Yes they dont use props.

These are cold fuel engines. No carbs etc.It uses thrust.No props are needed

Thanks for your reply. I will investigate the issue of using a servo directly to the pins which drives the ESC and use the same power source to drive them. The reason I want to use gas engines: 1. They are quite robust 2. They dont need propellers 3. The are faster 4. They can reach higher...

I have designed gas engines to be used with drones. The problem I have is that the esc cannot control the servo which opens and closes and regulates the fuel into the gas engine. Does anyone know of an autopilot which could control six servos in the same manner it controls the brush less motor...
