I got confirmation that the car shipped today!! It should be here by the begining of next week!!!

here are some of engines I'm looking at for the rc10gt. what do you think is the best option? I also don't know which shaft I need to make it works right. I'm probably going to get either the 18tz or the 12 tz if I can get a pull starter for it. I may also go with the 18 CVRX since its cheaper and I have had one before and I know its a great little motor. and in case you can't tell I want a pullstart motor. lets hear you opinions!
Thanks
