Hello all. Merry Christmas and a Happy New Year. Very interested in these tinker machines. Have a back ground in gas RC 2 stroke engines. Some of the 23cc in boats. 50cc 55cc and 100cc in planes. And 2 stroke outboard motors. Looking forward to playing with these. I like the retro/vintage looks. So many different personal touches can be made. Hello all and thanks for taking the time to share your knowledge and experience.
