i almost forgot i really need to thank you for the idea. when i saw you were building a genesis crawler i just had to see if i could build one with some spare parts i had with the thunder quake. i ended up throwing out or scrapping the whole truck except the forward reverse on the tranny and the 2 speed gears (converted it to a single speed), and kept the diffs.if i knew now that i had to built the whole truck from scratch i think i would of waited to get the ax10. but now after seeing this thing almost complete i am glad i did it and had fun and learned alot what manufactures go through in desighning these things
