Hello Thomas. Can you tell me if you really like the UMS 100CC RADIAL 5? You don't see a lot of movies ... no movies at all,,, here on youtube about this radial engine. I like this 100cc radial. Maybe for my waco 1: 4 scale, so I am very curious how it performs and its reliability. Anyway it sounds great!! Thanks in advance.
update new prop size is 26x10 more power on air than 24x10 . dia is less 243mm , ecxatly 240mm. perfect radial engine for aerobatics 60cc 2t planes, 60-80cc 2t warbirds , (up to 100cc sport or scale planes if the weight is not to much) new test fligths have show us to uise the bigger size prop 26x10.
