Been back into RC for the last 4 years....after a 25 year vacation, ran drag brakes with 1/12 scale back in the 80s and still run a lot of drag brake to this day (I also run a front diff). I run 17.5 TC and USGT and I have yet to see higher temps from using drag brake, no higher than my competition that run little to no drag brake, we come off at very similar temps.

Drag brake allows me to let off later and get back on throttle to ensure I'm accelerating as I exit the turns. Considering I'm 64 yrs old and lacking the reaction times I once had I still manage to run with the big dogs at my track.

A lot of people perpetuate the drag brake myth, use what works for YOU!

It really depends on what makes the car faster(lower laptimes) and more consistent... I started with zero drag brake with my Novak 17.5t : I had no braking power, and was overshooting every turn... At full drag brake, I was still without decent brakes, so I switched to the Fantom fr-1 v1 and bam, way too much brakes/drag brakes at zero drag brake settings. I ended up with 88% forward on the throttle trim to keep the car from jerking back and forth when I come off the throttle at every turn: that gave me a consistent car that was very predictable and my laptimes went down alot...I still had crazy brakes when necessary, but I was never really using them since the car was rotating so good and hitting every turn right on the nose....

Reviving this one too instead of starting a new thread... even though I race 2wd off road, I believe it applies for both.

I noticed that the cars of the top racers at the LHS "dart" of a turn a lot faster than most, seemingly more torquey. It's almost like the car has instant torque, more agile - one of them has the same car, motor and gearing as I do and his looks to pickup speed faster off a corner.

Can that be a result of more drag brake on their cars, so it looks like the car is darting of a corner faster but it's actually just speeding up from braking, instead of from a rolling/coasting?

I originally run 0% DB, and now got mine at 40% and it does create the impression of more torque

I think that you would find that maintaining energy and speed through corners would be more important. Coasting is not bad, and what you may be seeing is kind of an illusion due to a car that you are watching can seem faster than when you drive it.

I think drag break is great when you are just learning but if you want to get faster, you need to get off the nipple. If you want to learn how to drive with no drag break? drive nitro and you well learn.

I use drag brake at a higher percentage when getting used to a new layout. Then I lower the percentage after a run or two. What I find is that motor temp actually goes up doing this. That is because I’m not being as efficient at braking and slowing down at the corners. But after a run or two with lower percentage drag brake, I find that my lap times are now faster without as much drag brake. So you may want to try using it this way to help train your reflexes for a new layout.
