Hi Avim,
In hot climates engine temps can climb quick especially with a tight cowled engine. What coolant are you using? 50/50 mix I hope and not Evans. What type of radiator do you have? A standard flat radiator type or a heat exchanger with oil and coolant in the same device?
Spend less time on the ground. I see some spend a long long time on the ground doing checklist and run ups. Do this stuff quickly and get moving out to the runway.
Check all coolant hoses to make sure none have a reduced radius from making too tight a turn. Make sure your coolant radiator is clean on the inside.

I hope a couple of these help.
