Yea it was for fun ;)...I don't have duplicate 5mm 32p pinions....I soldered up my E-Revo setup today and thought I just had to this ..lol... I may order an extra pinion...I will have to run a bigger spur than 62 I have on there now cause the second motor won't mesh because of giant neu case... 68/24 I know will fit for both maybe 65/24 too...when I order from mike again I need a extra 4s battery also......
