Hello everyone;
My work in progress is a BikeE2 Recumbent tandem with a Honda GX35 in the back. I have a NuVinci Developers kit for a rear hub, and a Staton inside drive. I have a nice, low, tight mount for the engine/drive, and a good hookup to the rear wheel. I can pedal, shift the front derailleur, motor, or combo. The Nuvinvi shifts automatically either way, so I am semi-automatic even when pedaling. I am gearing for hills, and in spite of the small motor I believe I can climb a ~16% grade (engine power only) with 2 aboard, and go 20-22 mph. The 20" rear wheel is a big help in that respect.
My problem is with my throttle cable. By the time I go from my twist grip at the end of my longer handle bars, to the engine, it's almost 10'. So, in spite of the Staton 100" throttle cable, 2 10" extensions, adjustments, graphite, extra throttle springs etc., I still have too much cable friction.
RC modellers use this engine, so does anyone have tips or tricks for a servo with a wired connection to my twist grip? I have 12 volts available, and I could have 6 volts + 6 volts as well. I have a charging system, so using one 6 volt battery more than another (even if they were in series) would be possible. I will finish my rounds of the RC model shops tomorrow. Amazing how many of those folks know little about the innards of their products!
Thanks all, in advance;
Bob Davis
