Default Can i put a JPX .28 in my RC8?

I got the RC8 RTR about a month ago, and realized the pro .28 just isnt doing it. would i have any problems if i was to put the jammin .28 in it?

you can put it in there just fine but that is way too much power for racing. a jammin JPX 21 is plenty fast for a truggy. but if bashing the 28 will be fine, it will have more power than you can ever use. a stock jammin 21 is extremely fast and if high bite track you will hit the wing pretty easy. either one youll have one of the fastest engines out there, stock engine that is. also look at the ofna JL 21 extremely good engine and its only 175.

keep the pro .28 and you could spend about $50 and have it modded. If your just going for fun. If you plan to race i would recomend a .21, since any larger is illegal.

IMO, before you consider modding...try a top end oriented pipeset. Ofna or Dynamite 086 or Jammin JP series...I think the 3 is the top end version. Consider changing your clutch set up too. Or at the very least, take the bell off and clean things up. If you're going to buy a new mill, I agree with the general consensus, .21 over a .28.
1) If you're going to race, technically .28s are illegal for buggies (I'm assuming you have a buggy, not a truggy?) Granted, your local track may let you slide, but if you race any sanctioned events, they likely won't let you run a .28 in a buggy. If you're only bashing and are merely out for all out brute power, then enjoy the .28...but keep in mind, being a larger mill, it also has a larger appetite.
2) Another thing to consider is that you'll likely need to also get a starter box, I don't believe any of the Jammin mills are available as a pull start, and I'm guessing your current mill is.

Running in the snow is not a good idea. Water will go into electronics and will make metal parts and screws rust.

For the engine, if you don't race, keep the stock .28 and add aluminum clutch shoes and 1.0mm clutch springs. This will increase acceleration. Also, make sure your engine is correctly tuned.

If you absolutely want to replace the engine, buy a new one (and a tuned pipe) and keep the .28 as spare.

Ya its not worth it in the snow. Have you got a set of ALM clutch shoes yet. That will make a big differnce to.
