MGM Compro Worth it or not?

[tom255]

My friend bought MambaMax and with half charge of 4S its arms and fully charged 4S LiPo its not arms
Yeah I tried to use Plane ESC and with mech brake. It worked but response on trigger realy bad. No chance to correct trajectory on jumps then car nose diving. Realy uncomfortable to race even nitro truggy feels much better.
Second i want shave weight off so much as i can. We have 3*15min mains so I can save some weight on batteries.
Now i have mixed feelings do I invest money to ESC and save on batteries or vice versa.
In my opinion $150 for car ESC its OK, if pay more only if it worth it so why i am askind about MGM's
