Hello i'm new to nitro engines and i have a question i just got a used T-MAXX that has a .15 motor not to sound too dum but what is the diff. between that one and a ..25 i heard there almost the same

We don't allow "Nitro" engines here, "Glow" engines are fine.

Take it to the R/C Car engine forum, better answers for you there.

But addressing your question - any 0.15 engine is only 60% os the size of any 0.25 engine. And the 0.25 engine will usually be about 60-70% more powerful than the 0,15 engine.

No big deal, it's just that none of these engines require nitro to run - "Nitro" is not a correct trem for describing them.

Using the word "Nitro" was a cheap marketing trick to attract kids to R/C cars, it still irritates most modellers other than the car freaks. And maybe some R/C car hobbyists are irked by it too.

I think he had the decimal in the wrong place and the .15 engine is the same displacement as the 2.5 engine. .15 cubic inch is the same displacement as a 2.5 cubic centimeters.

Could well be.

Before my irvines and MVVS became diesel they ran fine on FAI fuel, (hot plug) martin

RE: question
 

engine size isn't a very good indicator of power either, especially in the car/truck ranges of .12 - .28 or so. There are some expensive .12's that have as much or more power then a cheap .18! (price might be a more accurate comparison then size actually!)

RE: question
 

i did have the decimal in the wroung spot Sorry

[b]Mark:

In that case, your 0.15 cid engine is the same as your 2.5 cc angine, as pointed out by Paul in the sixth post.

RE: question
 

They are the same size, but configured differently. The 15 is side exhaust and older than the 2.5 which is rear exhaust current and has more power.
