Honestly, I didn't work out to build my sparky 2 with brushed motor. The spark 2 was a chinese clone board, and my friend purchased for me because I live in Taiwan. I found that sparky 2 has many problems, such as bad pressure sensor and crash on uploading firmware, .. etc. I finally give up my sparky 2 and plan to buy another one, as the follows. http://www.hobbiesfly.com/taulabs-sparky2-0.htmlhttp://www.hobbiesfly.com/TauLabs-Brush ... y-2-0.html
The flight controller is usually light weight so will not cost too much for shipment. It might be a good solution to be considered.
I am not sure what manufacturer of your sparky 2 is? It should work as the peady124's video footage if you got from the hobbiesfly store. You can also check the BOM for parts. https://github.com/TauLabs/TauLabs/tree ... sparky2/hw
I guess there must be something wrong with the Q1, Q2 on my sparky 2. It is difficult for me to check out what type of those 2 dual channel MOS FET they use? I am saving money and plan to buy another new one directly from the hobbiesfly. It would be better have the same flight controller board, better than those chinese clone boards. Not only playing brushed motor with sparky2, but also we can use in ROS and LQG, and so on. You can check those topics with Dr. peady124 in this forum.
