IMHO, not only the $140 is way too much for the value (I will know more once I start using my 403 on rocky shallow areas), but the whole concoction looks somehow overwhelming: there is a "functional debt" incurred when convoluted solutions are applied to simple designs. In this case, the Ultralight assembly is already debt enough
In the same page, the vendor shows a $50 warped tube to lower the motor 2 inches: look closely at it, and it is just bent mechanically (you can see the tube compression on the bends). For $50, I nuy me a great vise, bend it myself, and keep the vise as extra
