I run both .21 and .28 on my 8ight-t. When I'm on a big track I run the .28 GRP and on a short track with lots of turns I run my OS Vspec. That's just my opinion and it works for me...

Go with the 21 i ran the grp tuned 21 in my 8t. I now run a ninja jx21 it has more power, this is a very fast motor.

to tell you the truth i not had the motor in a losi but i have had both in my strr
for me the 28 was decent but hard for me to drive to much low end and way to much wheel spin

when my 21 right it as fast as a 28 up top but not on the low end i dont need a lot low end just give me mid top and let rip
