It's our first big MB.com challenge, for the 35 r/s crowd, to get a simple yet proven system, provide a 70-80 mile striking distance between refuels.
It's going to take a "dual-tank" setup, the only one I saw in the GEBE review page was this one from So. Cal:

Same with the Tanaka, I was spoiled on the Zenoah 25cc- getting 45-48 miles per tank, and need a set-up to get maybe 60-70 miles changing to a 1.5 liter.
Talking to Dennis the other day, he told me more about the 40cc Tanaka and the specific applications they are used for, so anything we find should be useful there also.
I don't think the answer is the 96 oz tank...
We'll get a MB.com certified setup, somehow...
