1. 如果要energy果隻saddle pack Lipo (7.4V),是否需要改位才可放上?
--> The saddle pack may be too high for 1/12 bodies. Maybe you can try 1S lipo and mount it on 1 side; esc + receiver on the other side.
2. 用上面隻Lipo + 黑豬是否已足夠新手操練? 我驚brushless太快....
--> 7.4V + Black pig, speed is ok, easier to drive, but motor will get hot.
But 1S Lipo need to add booster.... anyway I will think think....
--> 2 options for 1S:
a) booster
b) battery receiver pack. There is a LiFe 6.6v receiver pack from IP, size is small. I never tried it, but it is a good option.
One more question, is it a "MUST" to have a 磨tire機?
--> It's not a 'must' item, but its 'better' to have since foam tires will wear out pretty fast and not in regular pattern. I don't have one.
If you are serious in 1/12 or 1/10 foam, then get one. If just for playing around (like me) then its an option.
