k i want to replace the stock engine in the warhead to one of the AXIAL engines. I want to get AXIAL .28 but their's two of them. What's the difference between the Axial .28 Spec 1S Engine Green and the Axial .28RR Spec 1S Engine Green? I know that the Axial .28 Spec 1S Engine fits in the Duratrax warhead, but not sure for the Axial .28RR Spec 1S Engine.


Here's the link to Axial .28 Spec 1S Engine Green : [link]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXPDU8&P=ML[/link]

Here's the other link to the Axial .28RR Spec 1S Engine Green : http://www2.towerhobbies.com/cgi-bin...&I=LXRVJ1&P=ML

Heres the deal, the regular Spec 1s is made in green and grey heads, its one of the most reliable and bang for the buck basher engines other than STS It is very easy to tune and break in. The Axial RR is the "racing" version thats a bit more finnicky and takes longer for break in. If you are just going to bash then the regular .28 is for you, both make good power[8D] Also, they will both fit with no mods but the RR needs a good pipe to work properly[8D]

Thanks for the help rcnitrohead. i will be getting the Axial .28 Spec 1S, now that i know the difference =)

That is a good choice, runs reliably, super easy to tune, and it loves 20% fuel, with a Med. plug. If you run it a tad rich, it won't kill plugs, and it still puts out a ton of power.

Glad to help you out bud[8D]
