Rainy today

Rainy condition today prevents me from going out for R/C flight, though all the batteries had been fully charged, how come? Coming Sunday is prepared for Pylon Racing at our flight place, so I must give up the flight this week. Consequently, my free today would be spent for preparing the new one, Majestic.
Wounded finger has almost recovered after a week interval, no tendency to be infected by bacteria nor bleeding again, fully covered by newly born epithelium tissue.
It is often the case that the models are suffered from the overheat phenomena of the motor especially 4-cycle on scale model with fully covering would. The cooling air flow is not enough to keep the cylinder temperature at some adequate condition leading to unstable rotation and some times motor stop. Though I have never experienced such an over heating condition, I applied air flow holes on the Su-31 as shown. Because the covering on the head top is fully opened, no overheating phenomena would not happen on YS 60 SR motor on boarded.
