Just listen to me, and get 30.
Tune accordingly and watch your temps for a tank or 2, You will never go with any other fuel once you have experienced torco 30, I put my word as a man on it
I must say I have had a few vx .18s and only recall reading temps of 230 with a leaner tune when doing top speed runs, but the fuel I use is higher nitro percentage and is known to reduce running temps while still being a safe rich tune vs many other fuels
210 is a bit high, especially during break-in. Keep the temps under 200 for a few more easy running tanks, keep full throttle pulls to a minimum until you have around 8 tanks total of driving around ran, I also do 3 tanks at idle, first tank just barely enough throttle to keep it running, second...
