Its been a few days now i was researching what they have changed and i have some questions for some things they have changed because it seems that every year they have to change something to get more money..
Lets start from the v-one rrr version..
ok to convert the rrr to evo they have changed the upper deck and changed the position of the servo from laydown to upright.. and if you see now on the evolva m3 they use the laydown position because some people prefer the laydown position..so the question is why did they changed the upper deck and the servo mounting position? what is the change in perfomce?
also the other thing they have changed is the rear bulckheads and the only reason i can think without looking on the new and old ones is because they use the new 2 speed axle. but on the other hand they could have use they same stuff and just change the brake hub to aluminium..
so again what the point of changing most of the rear end ? why did they do it? what is the difference in perfomnce from the rrr?
another thing they have changed is the shock body and the springs..
ok for the springs i can understand the body shock why?
also the have changed some other stuff like new spur gears and new o rings but again i am thinking if i spent 290 dollars to change most of these parts does it worth it? or is it better to buy the new evo2?
i dont know i am totally confused...
On the question regarding the change to the laydown servo on the upper deck for the RRR EVO. The change was for a lower center of gravity (CG). I didn't care for it because it put the servo horn and linkage out to the side of the kit where it was exposed to getting hit. The kit did come with a small plastice brace to protect the servo but i just didn't like the setup.
I may be wrong on your question about the rear bulkheads but I believe they are the same from the RRR on up to the RRR Evo 2. It's my understanding that the Evo 2 simply has longer rear control arms so you don't have to run 2 degree offset tires. The reason for the lightweight 2 speed shaft is for less rotating mass as that shaft is hollow.
As far as the shocks go, I'm not sure why they went with a different shock body. Maybe someone else can shed some light on the reason for that.
On the new 2 speed setup for the Evo 2, it is from the Evolva M3 and is simply smoother than the the Evo 1 version. As far as the new 2D clutch setup, the verdict is still out. I initially didn't like it but have since added 2 grub screws to each weight and have gotten it to work to my liking. Without the weights it just didn't have enough snap on initial engagement. I have a few motors and on my other Sirio Evo 4 STI I am running the CRF clutch setup from the 07 CRF WASP .12. That setup has a mutch stiffer spring and 3 weights and seems to work quite well with that particular motor. I am thinking of getting the Sirio clutch setup as well.
As far as going out and buying the Evo 2, I guess it just depends on how serious you are about racing and your pocket book. If you're just getting into it you may want to get your feet wet with this RRR and then little by little build it up to the EVO 2. If you have been racing for a while then you may want to get the RRR Evo 2 and use what parts you can off the RRR for spares. Hope this helps.
