Default Losi 8ight-T RTR To Pro Conversion

I have an RTR on the way and I was thinking of picking up at pro just for the upgrades and then selling the RTR roller. If there is a lot of difference between the two I can see this being a good plan, but if not there must be a better way of going about this.

Could some knowlegable expert please let me know the difference between the Pro and the RTR?

What the best route would be for upgrades?

I eventually did this with my 8B rtr and to avoid it again got the 8T roller.
The 8T rtr has stamped shock towers and chassis, plastic shock caps (top and bottom), the hinge pins and shock shafts aren't Ti-Ni like the race version. That is pretty much it. The diffs and plastic parts are the same, same goes for the cvd's and shafts.
If you are going to race then I would recommend getting the shock towers atleast. Or just get the roller, but they aren't cheap unless you got the $$$ to spend, in that case go nuts!!

My advise is to run the rtr, it definitely has the balls to run with the R-roller. Just upgrade your radio and transmitter. The rtr radio doesn't have expadencials (adjustable servo speeds) which makes the truggy very twitchy. Also to get rid of the frequence band (convert to spectrum) and get some bearings for the steering rack and some aluminum inserts for the rear diff. and you should be good.

rtr kits vs. race kits have many differences not just the shock towers and chassis, especially racing them.

What are you on about the RTR comes with DX2.
I know exactly what the differences are I have had both....have you????
The RTR comes with steering post bearings.
Getting the Aluminum inserts is a good idea.

On my conversion from 8B-RTR to Pro the shock shafts, shock pistons, hinge pin holders (stamped), engine mounts, wheel hexes and nuts (just different color), rear chassis brace (only one screw hole on RTR), were all different as well as what BOOST has mentioned. The RTR 8T has a different body shell than the Roller, if that's a big deal to you.

When I converted mine it cost half again as much as the kit did. I learned my lesson. It's not like it's hard to build the kits anyways. There's no college degree needed to put them together. I was just scared at first. LOL. Now I look back and laugh at myself.

He means to put bearings in the draglink, not the posts.

Yep those are the other things that separate RTR and the PRO. I got the RTR to begin with for the whole package and as I raced it I just upgraded the parts but it was a bit costly. I am glad I done it beacuse I now know these vehicles inside out so when it came time to get the truggy I went straight for the Race roller. As far as setups between the RTR and PRO goes the RTR comes with a userfriendly one and the PRO comes with a good all round race setup. But they are both equally adjustable.
Changing the engine mounts will mean getting the sportwerks backplate for the TL427 and using a starter box. I done that with mine and there is noticable power increase from getting rid of that extra rotating mass. Plus you dont have to worry about any of that wearing or anything like that.

Well I think you guys helped seal my decision. I am going to the Winter Nationals and want to make sure I have a good supply of parts. If I buy the Pro roller I will have my RTR for parts and then I can sell it afterwards. I can see spending $200-$300 buying the individual parts. Thanks guys.

Some people have traced their steering slop back to the bushing that the ackerman plate uses. A few people have managed to use bearings in place of these bushings, but I don't think this has been used by too many people. The people who did change them were playing with their toys and they found a way to make it work. I still have the bushings in my 8 and 8T, I don't think I'd notice much difference on the track. FYI

Yea I do notice a bit of slop that I also traced back to the bushings, but it doesn't worry me at all I still have full control and they turn just as good as when I first got them!
