Default New Engine Question

I am just starting to understand tuning engines and would like to upgrade from my Go 3r engine to a v-spec or an O'Donnell ss .21(I have a Z01B). my question is, which of these two engines is easier to tune? are they about the same? I am kinda looking for the ford f-150 of rc engines one that doesn't need to be played with all the time and just runs well. I know i have to tune the engine each time i run but i am sick of chasing a tune in my Go engine. thank you for your time.

One of the biggest selling points of the v spec is the ease of tunning, very reliable engine, plenty of power for buggy or truggy and great runtime's. Not to sure on the OD SS, havnt ran one yet, but i can say you cant go wrong with the OS.

get a ninja or vspec. O.S. engines are the easiest to tune. And the ninja will have a longer lifespan.

I would recommend the Ninja engine. It is made by O.S. It is very similar to the V-Spec.

How long will a typical Vspec or Ninja last? I've heard that a Vspec wont last very long.

My first V-spec got 9 gallons, the second only got 6. I'm now trying a RB WS7 and I've herd that 13-14 gallons is not out of the question. We will see.

From what I see at the track the ninjas last longer. In some cases ALOT longer. Never seen a broken ninja case or worn crank & carb bellows seem to last longer but bearings I havent asked about as most I know replace those with TKO after break-in out of habbit with all motors. I will never buy another v-spec but from what I see at the track would not hesitate to get a ninja if I needed another motor.

another really good engine you might want to consider is the Jammin JPX.21 i have one (just got one) and it has TONS of power. it'll hang with the v specs all day long. and once i get her tuned in in practice, i dont have to touch it for the rest of the day. (unless the temp changed drastically). and the jammin is only 239.99 or something close to that.

I have a vspec right now and ive had many issues with it, but my dad had one for 9 gallons, he didnt even change a bearing or conrod until the 9 gallon mark. He changed the bearings and put a new rod in then it lost compression like 1/4 after that which i thought was funny.

i would advise a ninja, vspecs are nice but you gotta change the rod after break n to a ninja or speed rod. thats where most fail
