I have a Caldera 10e going on 3 months now. I made the decision to go with electric as I read through the many posts of challenges with nitro powered engines, so the reliability and ease of electric was was convinced me to go that route. It used to me that nitro or gas based models were faster and more powerful, that is not the case any more with the new electric motors. I have had a very positive experience with my Caldera 10e. It has been durable without any issues.
I agree. Electric has come a long way. Brushless technology is up to date. Nitro is not, but I love nitro. The sound and smell. The only issue I have with electric is still the batteries.
If you really want to be equiped to take your equipment out to the track or a local park, you need 3 or 4 batteries if your bringing more than 1 car with you.. Then if you want your batteries to last they need to be charged and balanced properly. You can find cheap batteries all over the web but most good quality lipo batteries are no cheaper than $50-$60 a stick if you want good run time and a battery that doesn't lose a cell every 3 months.
Same thing with the charger. You can find plenty of good, cheap single lipo charger/balancers for under $50 but if you have several cars and a stack of batteries to run them your going to eventually want a multi charger like the hi-tec 4 bay charger. That's another $200. For me the investment is too great to go all electric. Right now There is 4 RC cars in my house not including the 2 sumo's. 3 are nitro and 1 is brushless. If all of them were brushless it would cost me a fortune in batteries and charging equipment.
