[elijah]

I took the predater outrigger plans and enlarged them to build a 32'' rigger it came out grate totle wate redy to run no batt. 4.2 lb. running on the ul1 motor and esc using the turnigy 5.0 40-50 c brick that is 20.6 oz. I am running the octura m447 and getting speeds in the high 50s to the low 60s blistering the other racers in my club hawever after the 5 lap race my caps and motor are so hot they will blister you if you tutch them hawever I am not getting a smocking genie I think I need to use a smoller prop but I am a newbe and can't figure out what would be a good prop to use to cool down without loosing any speed or as little speed as posable. can any one help. thanks

Dear Elijah,

Definitely start with smaller prop. For same configuration I would start with 38mm prop and work up little by little.
