Sharing my flights with an electric E20 model. (Electric , 20 inch WS) and mine weighs 34 grams.
It is flown with a 8.5 mm motor, 20 mm long (8520) with 1S , 150 mah Lipo battery that also activates the DT servo (1.4 grams). Plans are in the description. Based on some discussion threads in the Electric, I gather all these are available in India.
Not too many places to fly a 15 or 25 size , 60 inch free flight gas model. But the E20 can be flown in nearby parks or gardens. Just assure that there is enough stab tilt to make smaller circle and keep it in the park. Give it a try, sure is fun.
Hope you enjoy.
