Few more pieces of information that you guys might enjoy: 1. We tested the above Tiger tank with 450W motors <https://www.youtube.com/watch?v=ANdYtKEtDCM#t=41> and 250W motors <https://www.youtube.com/watch?v=ASUPM0NWruQ#t=26> - I have linked the respective videos of the runs, and you might observe little difference of performance in the rough. 2. Tiger with 450W motors reached 5.5mph max speed on Asphalt, and 3.7mph equipped with 250W motors 3. The second video (GoPro installed on the turret, 250W motors) had a LiPo battery system <http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=16786> (2 in series, 2 in parallel - 11.1Vx2, 5Ahx2). They are 0.9lbsx4 = 3.6 lbs. It saves 20 lbs over the two 12V SLA Batteries!
I did some research on how we can test the life of these batteries <http://flitetest.com/articles/LiPo_Battery_Internal_Resistance_Testing>. LiPo should be stored at 40% capacity, and SLA batteries should be stored fully charged (with a trickle charger). I'm reading that LiPo have 300-400 charge cycles (up to 1,000 if treated well), while SLA Batteries have 10 yr-design life. Thanks to Will Montgomery for his advices on the LiPo battery system Loic -- -- You are currently subscribed to the "R/C Tank Combat" group.
