I have one. Not played with it yet, will be used on Sunday for my first post-lockdown skirmish.
The new internals are pretty good - I've no plans to replace anything inside the GB until it breaks. Stock motor is torquey but a little slow (11-12 RPS on 7.4v LiPo).
I have:
- Replaced the hop rubber and nub (had a TM spare)
- Removed the fuse and added deans connector
- Changed the fire selector
for this one
- Re-shimmed and re-greased (to be fair it was decent enough on both counts out of the box)
- Rocket 16TPA Hi-Torque
I'm very happy with it so far. Can't comment on longevity yet though.
Pics of the internals.
