The "roller" weight is in the 2750 region. But there is many heavy Steel parts that can be swapped for Alu dito.
I ligtened my ECO (which is quite light) with every possible thing nearly and it stopped at sligthly above 3400. Titanium,CF and Aluminium everywhere. Those 200g was NOT worth it in my oppinion. I think the most important thing is to keep the unsprung mass weight down. Normaly the rotating mass also but with those motors I dont see any problems to get it moving.(The drawback maybe the counter rotating mass. ) The guy that bought it swapped the Alu chassie for an CF one and has shaved another 100g off.
And this is real fact without any fantasy numbers.
I agree, my tekno mbx6 is a shopping trolley with food compared to my mbx6 Eco. Especially with 6500 maxamps lipo for 15 minute finals. But it's solid and I dont feel the weight especially with a 2250kv hobbywing motor.
That said truggy is a beast but 2000kv with 6500mah will only get me 19 minutes in a final. I feel the weight draws more battery power.
Either way. Some one is going to get rich by designing a battery pack which can just slot in like those old nokia phones and a cover like the hyper 8.5 fuel tank draw string.
