I'm almost done with the wood work for the boat and I can not proceed any further until I get a motor and speed control system together for a dual drive. I had planned on using the Astro Flight motor that I have in my PT boats but they are no longer being made and the replacement is $400 each. I paid $125 each for the ones I have in 2002-2003. That's no problem because with the AF motor mount they are easily removable. Now AF doesn't make them now also. I sent a letter to AF to get two of the motor mounts or send me the drawing and I'll get a local machine shop to make me two. I got no response. I will now have to reverse engineer the mounts and make my own drawing. I'll try that first. If that does not work out I'll have to some experimenting with a brushless motor and control that has the same Kv value as the motors I have. I know very little about brushless motors so if I don't hit it the first time, it will take a while. In the mean time, I'll go as far as I can with the boat and stop when I have to. In the mean time, stay subscribed. Dan.
