<http://www.pridemobility.com/quantum/powerbases/rearwheel/r4000.asp> Has anybody had any experience with r4000 by pride? I will require sip &puff control system along with tilt seating. According to the manufacturer numbers top speed is pretty decent but I'm wondering at the cost of speed versus distance? I can cover large geographical area let's say in six hours and I am currently using Invacare Ranger X. gearsless brushless motors. I have had this set up for the last two chairs and absolutely finish dealing with Invacare serious electronic problems! So battery life, motor durability and electronics are my most essential areas of concern within the chair may choose early next year. Thanks from Indiana Monty 3/4 16 post injury
