I had a CCRC 26 and would not recommend it . If you prefer glow , 4 stroke Saito or OS would do , YS would cost more to operate as it likes 20% nitro . I have gotten away from glow and am running gas . To make it truly a SUPER cub I would use this motor w/
1/4" x 32 spark plug and it fits into the cowl
