Topflite P47 Gold Edition
Just getting back into the hobby after a long layoff and I am just starting to build the 60 size TopFlite P47. I would like to power it with OS 1.20/4stroke (for the sound). One review I read said that they first installed a ST90 but due to cooling problems went to a ST75. Do you think there would be a cooling problem with the 1.20? (May have missed it but haven't seen this addressed in any of the other forums). Thanks, Dave
