Gemini 4 blade propeller

I recently received a 4 blade propeller in the post to try out on my Gemini craft. Going from my experiences with my smaller craft it should be quieter and more powerful. Well it certainly seems more powerful but its a lot louder! There’s also another issue where its drawing so many amps that the ESC seems to be getting too hot and cutting out. I am not surprised really and even the wires themselves are getting hot! I think I will switch back to the 2 blade for now.

e-Gemini on its first run

Here is my first go at piloting the craft. It feels a bit nicer to control compared to the smaller craft because of its extra weight and size. I have not used it enough yet to know whether or not I need to adjust the center of gravity. It may look a little twitchy in the video but I was trying to keep it in a small area away from any cars so did not give it a proper straight line test.

Something I forgot show in my previous post is the electronics under the hovercraft seat.

Here we have a 5000mah 3 cell Lipo so plenty of speed and runtime. This connects to a brushless motor ESC which connects to the brushless motor and receiver. The receiver is an ar600 aircraft receiver. Aside from sending control inputs to the ESC it is also connected to a servo at the rear of the craft to control the rudders. A servo extension cable was required because of the distance and the fact the cable had to be run around the duct in order to make sure it was safely away from the propeller.

Getting back to the e-Gemini

Funnily enough the e-Gemini was the first hovercraft kit that I brought way back in 2013. Unfortunately because of the space required to build it and the fact it looked a little overwhelming back then I have put it off till now.

The kit requires a lot of manual Continue reading Getting back to the e-Gemini

Skyrider Drone Pack 9

As with my 3D Printer build there has been a delay on getting the parts to continue.

With the SkyRider I have received part 9 before part 8.  This is not an issue though as Continue reading Skyrider Drone Pack 9

I had some trouble with the brush-less motor when testing the car where accelerating or reversing would cut out the electronics. I managed to sort this by Continue reading Finishing the Blitzer Beetle
