"MK Star 06" almost completed

The general balsa figure of "MK Star 06" was almost completed yesterday, main gear and nose gear are not yet. Film coating procedure would be done on 3 small model airplanes, residual ones are "MK Super Tiger 102" and "PILOT Fighter". There are plenty of rolled films from some closed R/C shop last year, so any color combination will do as my choice.  In order to obtain the indispensable visibility from a distance about 150 m, some fluorescent color would be applied on main wing upper surfaces similar with the Rising Sun flag pattern.
I'm now considering about the power source of Star 06, Enya 09-4, OS Max 10 FSR or Cox 09? If Cox 09 is invited, either Medallion or TeeDee, exactly the same procedure done on Medallion 15 would be induced, carburetor holder one-off hand making with lost-wax casting method.
Any way, there are several high walls in front of me to be overcome, desperate effort would be exerted dreaming of being an applicant for "Old Timer & Golden Age Meeting" held at Uji Kyoto in this Fall.
To tell the truth, I have no air-conditioning system in my Hobby room, how come working at over 36 degree Celsius temperature atmospheric condition?
