The GM can be a bit tricky at first to set up but once you know it, its really not that difficult to get to grips with and the adjustablity has to make it one of the most tunable out there.
The amount of World and European championships the GM has won speaks for it self.
I don't know how valid my opinion is but here goes
I had the Tekin back when it was firmware 180 and it was good then but outpowered by the SPX. Its incredibly fast now, small, light, runs cool, great service, its a brilliant company, respect to them for developing a brilliant speedo
But whatever happens I always go back to my GM, spent a lot of time learning this esc, ver 4.8 till now fw13 it is just keeps getting better and better, sublime.
This speedo has rpm controlled timing, 1 ramp or 2 ramps, or intelligent high speed timing, or timing controlled by the driver with the stick (variable dependent timing - incredible), turbo (concept invented by ralf helbing at GM) drive frequency, three different types of brake sotware (choose the feel for you or your motor), telemetry and programmable temp shutdowns independent for motor and esc. You can read out current drawn, max rpm, temp motor, temp speedo. If you thermal at 4:30 for example you can set the current to a pre set amount so that you can finish the race at reduced power. And because of the telemetry you really learn the character of the motors you are using, and program that into you setting to take full advantage of your motors' capabilities as different brands have different tolerance to temps. GM120 runs mod and Delta winds awesome so I need just the one controller which is great.
Technically this is an amazing speedo, and it is years ahead in its technology. Their only problem in the past has been getting their ambitious plans to work, and I think with fw13 they have realised some of that potential.
The BD might be one to keep an eye on though. From what I understand, it is designed as a side project by Swedish satellite engineers. This speedo monitors many aspects of the motors performance, back EMF etc in order to calculate the exact amount of timing and power that can be applied efficiently and as such is a completely intelligent esc which is why it is so simple to program, and why drivers say its butter smooth like no other. They are working on a user updateable version so watch out for developments.
At the end of the day the only people who really know what is going are are the people who design these things, end users like myself are just...well, giving end user opinions.
So just an opinion. Just my 2c. Each to their own. Go with whatever works for you. The best driver usually wins no matter
