Magnum 120 4C for Excelleron 90, any good?
Planning to use Magnum 120 4C for Excelleron 90, will it be too heavy for this bird?
In addition, I’ve the Explorer 50 (I belive it’s the same as Excelleron 50) & planning to use YS 53Z 4C on it, what is the recommended prop size for this combo?
Thanks for the help!
