Well, first of all, you have the brushless RTR kit correct? The speedo: XP SC450-BL is sensor-less so that will limit your options a little bit but for starters I'd look for a sensor-less motor (or a motor that can run either sensored or sensor-less) that is 13.5 turns. If you plan on just racing stock/spec class then you are fine with that motor until it burns out or you have cash burning a hole in your pocket

There are plenty of good companies out there but I know Team Orion has some good sensor-less motors. Also, Fantom Racing motors can work in either sensored or sensor-less mode and they just came out with the new Ion 3's a few months back. Those are pretty good motors as well.

Thanks modturtle for all your help, I actually had the team orion motor/esc setup but I gave it to my cousin for his b-day...... I never got to run it but I'll check out how it is when he does......... I most likely will get a sensored setup down the line, but I gotta get better at racing first before I spend to much money on systems I can't even control lol.....

The stock RTR sensorless 3300kV motor is a 13.5 equivilant. If you are not happy with it's performance, save up and buy one of Fantom's Ion3 motors. I have their 17.5 in our buggies and they run great!

No problem Yeah, check out the the equipment in his car! You can always go to your local race track and most people there will be more than willing to help/give advice better than here on the forums where occasionally you'll get the trolls... watch out for the green ones

LOL thanks for the troll tip, most of the guys at my local track run sct's, and I've already learned alot of tips from them for my sc10..... Only a few run the b4.1 but their all stock like me... I will def. check out that motor....

No prob

Well, you can always post here with whatever questions you have! And be sure to use the forum's 'search' function to look for answers that have already been posted. This thread also has a TON of info in it; you can scroll back any time and see if your question is already in here

Sorry for the double post, my internet was acting up........

Double post...this guy's troll bait

ok im getting a new 8.5 motor for the b4...ive ran tekin in every other product but the orions look very very nice..which motor would you guys prefer?

The Orions are very smooth. The 8.5 is a good choice but depends on track size as well. Amain has marked the current Orion model line down in anticipation of the new model line coming out.

whats the new orions supposed to be like? ive heard its going to be better but whats different?

From descriptions I have heard the three piece can is now one piece. This will center the weight better on the chassis which was slightly off center on the current model. Better cooling.

anyone know the release date? i can run the 13.5 in the b4 till the new orions come out

Anyone come up with a better way to attach the front wheels on the B4's? I'm not real thrilled with the little screw that comes with the kit and I actually had the wheel come flying off yesterday when testing some adjustments in my yard. I'm thinking of a nylon nut on threaded rod or something like that.

That is unknown. The Orion website shows them in stock but none of the hobby shops have them. I would suspect in the next two weeks. The new ESC from them called the R10 is going to be a nice piece of kit.
