Hi Guys, thanks for your advises, they will be helpful. The franklin engine is a bit heavy, does somebody know how this affect my CG and what can i do to get the weight and balance ok. I planed to give up the header tank and make 2 tanks in the stubby wings and another one behind my seats. what do you think out of it. And finally is there a need for an oil cooler?? Over here it is not much hot during a year.
