Considering buying one of these. Many questions. Is lubing the drive a hassle(manual says 2 to 3 runs). If the motor is perfectly aligned with the shaft why would you need a flex shaft? What about putting a small spoiler on the front cowl to make it pop out of the water instead of submarining? Should I be looking at any other boats in this size before I buy. I like this boat because you can get all the parts on Amazon. If I get one I will definitely get one without charger so I can have my choice of charger and be able to plug into the 110 or hook it up to my truck battery. This is so great to have all of you out there to answer question and thank you RC Universe.
