- s9650 servo
Length:1.42 in (36.1 mm)
Width:0.59 in (15.0 mm)
Height:1.14 in (29.0 mm)
- HW 1S ESC
43mm(L) * 36mm(W) * 33mm(H, with cooling fan)
The HW isn't small..
Maybe I should have bought a 12R5.2

The 12r5.2 may have been a better way to go ,my mate used his new xti only twice before it literally fell to bits.
Had to order the new upgrade chassis kit,so it is now a not so cheap car.
