Keeps getting better the longer you watch! It kinda messes with your brain watching it.
That is very cool! (downright cold)
Iβm kinda new to karting but in the past I was very much into RC planes. Back in 2008 I started to convert my planes into EP. Some planes have a wing span of 72β. Those were usually flown with 26-40cc 2 stroke engines.
Lipo batteries were expensive back then, so were the branded motors and electronic speed controllers. EP was not popular at all.
But when the price of batteries started to tumble, many got into EP. Nowadays 90% - 95% of the RC guys are into EP.
With EP, itβs possible to get more performance out of our planes. Much more than ICE ones. For the standard sized planes it was not possible to get a 1:1 power to weight ratio on ICE. Despite EP being heavier, it was fun to see the plane pull verticals with ease. Almost unlimited verticals.
It all boils down to cost.
