Which way to go with the XT8? What are the pros and cons. In my opinion .21 - good engine has enough power - low fuel consumption - is lighter than .28 - has higher revs and gets to high revs faster .28 - lasts longer - cheap or average priced engine has enough power - runs more stable - eats more fuel When I don't need the BEST engine yet then maybe .28 is better option? Or if I need the BEST engine, then very good .21 is better choice? |

But why should you ever choose a .21 then... so why not to choose .28 and go for .21? |

it is easier to get the power of an .21 to the ground than get the power of the .28 controlled. Most people don't want to spend time on set-up. In a Truggy a .21 is easier to drive. The good .28 has got a huge torque, most drivers can't use to be faster. But if you can use the extra power, you will have the better laptimes... You just need a better Set-up to get the power to the ground. Further some cars do not last long with a big block, the XT8 has no problems to handle these Motors. I am real happy with the XT8 in combination with the Ninja .28. I have the revs like the people with .21 but out of a corner I have much more acceleration (if the set-up is good) |

IMO it really comes down to "how good of a driver are you?" (I assume you mean for racing??) If you are very smooth, and have a smooth trigger finger, a good race 28 might well work for you (os or ninja 28) - they are brutally strong though...most people (except for one good driver) I have seen run them have too much power on their hands and are all over the track. I think most people would be faster on the track with a good race 21, which, in all honesty, most of the racers cannot utilize to their full advantage.... |

In a Truggy, your speed is limited by RPM, and no .28 that I know of out revs a good race .21. Most high end .21 have more than enough tork to spin the tires, so theres really no need for a .28. |
