The engine also makes power quickly so its still snappy yet predictable .
MASSSIVE !
well the new servo arrived so took it to the track today..motor fires so instantly it just amazes me ..buggy was nice around the track but after a tankful to warm it up it started to make a grinding noise so I pitted to find the bearings where the centre driveshaft enters the rear gearbox had died again..3rd time in 2 weeks so I decided to take it apart ..anyway turns out when I broke a tooth on the small pinion 3 weeks ago it also buggered the teeth on the main diff pinion..I didn't notice this so just replaced the small gear..so now it's ground the teeth of that one again and it is the heat each time that is destroying the bearings..Replaced both pinions again and off to test the MG66 some more..DUH! look properly next time..
Oooooooooh feels like I got new buggy..seems I have been driving a front wheel drive buggy for a while..damn that back end must have been slipping for ages..anyway I'm running not only 3 alloy shoes with 1.0 mm springs which alone would be enough to bog the 7 port..but I also upped the main gearing from 13/46 to 14/46..motor pulls it easily and will happily lift the front wheels now I have some bloody drive to the rear.No wonder I couldn't leave people in my dust properly last weekend..DAMN!
this motor is the dog's nuts..!!! I'm approaching 3 liters and thinking of leaning just a touch for racing next weekend..havent even bothered to temp it as it runs so perfectly..was intending to use this for racing and keep the 7 port for club stuff and messing around but the MG66 is so much fun I can't see the 7 port ever leaving it's box except in an emergency..
grizz1 mate..wait till you geta couple of liters throug it..mines starting to loosen up a bit and really snarl properly..shit I can't wait to put the ceramics in it..Muahahahaha
