Not sure who's adaptor kit I have in there, but both packs are pretty well stuffed in there between the pinion and steering. Def no room for bigger packs.

Just looked at your pics again.
If I see it correctly you only have 2x 6s 5000 in there? When looking at Othello's Five-T thread (he drained 2x 4s 8000 pretty quickly with a 2028 and much lower gearing) that seems not enough even with the best lipos available. Maybe put another two of those 6s packs right next to the motor.

BTW, I really wonder about weight distribution as it is now, doesn't look too good, is it noticeable while driving? How about a proper UE chassis? Plus a 'standard' rear differential housing that allows for a straight center driveline? :)

the 2028 is nothing compared to the lerner 3080. There's a huge size difference.

I think the 'other side' of the ring gear actually works well. The rear driveline is nearly a straight line and there's room for a motor.

Agreed, balance is way off with all the conversions I've seen. I do have a 'proper' chassis on the drawing board, but to be honest, I'm so sick of every clown just waiting for ue to release something so they can do a crappy copy it for half price, my heart just isn't in RC these days. And the back biting and back stabbing....omg, it's just not worth it.

My two cents, don't worry about the copiers they are always gonna be around. That is their way, they know no other. Just FYI k about all the others in this hobby that appreciate people like you.
