pinion sizes and dp

[rondoolaa]

hi, does anyone know the shaft size on the anderson escape motors,

i have some small pinions that fit on my brushless but are too small for the escape motor

i have some for my 18th novak motor but they are too large,

anyone any idea's on the size i need,???


also what dp do i need so the pinion meshes ok with the standard lrp shark 49 tooth spur???

thanks for any responses
