Default RB S3 vs. Werks tl b3

what do you think of either one of these engines? My home track is very technical and the straight is only about 100 ft long.

These two engines aren't even comparable. The Werks B3 will blow the S3 into the weeds. The S7 is a closer match but it does not have the low end you're looking for.

I have both. The werks b3 was a bad a$$ motor for about 2 gallons. At about 1.5 gal. I had to replace the carb. Then at 2 gal. the motor runs strong until I go to refuel and then it dies and will not restart until I cools down. I noticed the front bearing was loose. I replace both front and rear bearings still same way. will not start when warmed up (200 deg). I resealed the engine no change. I just bought the rb s3 and got an awesome deal but I am still breaking it in so I am looking forward to put a race tune on it this week. will let everyone know what it is like

The B3 is great, but the carb is complete garbage. Replace it with a Novarossi carb (or Werks B7pro) and it is an awesome motor.

I recently got a B3 Pro and am very pleased with it so far and it has only run through about half a gallon. One big benefit the Pro version has is the carb has a composite coating to insulate it from the block.

So far the bottom end is really great, but it lacks the screaming top end of the S7 I ran before. But it should come alive soon and a pipe change will hopefully be a world of difference.

Well for not much more than these sport engines you can buy a Go tech and get a full bred race engine, which will have all the top of the line features already installed such as good bearings and a top of the line carb.

Thanks,
what level of a nitro driver would you call yourself? reason i ask is there are MANY engines that are in most cases too fast. i would get something very smooth then get faster as you progress. i have a c6 and to be honest its too fast and even when i only set the throttle up at 70ish% it still has so much bottom end it spins the tires even with a "soft" clutch. also to be 100% honest i have yet seen a propperly tuned .21 not be fast enough to be competitive (this includes engines like sportwerks .21 and thunder tiger .21 red heads) i would go more for dependability. sure it might be cool to clear quads and triples in a single bound but wreck once in doing so you probably lost All of your advantage in doing so.
