woah flaming an admin huh? you do know he is almighty correct? ok im sorry for getting in on that, anyway i just drove the revo today with the 1515 1y, and off alot of jumps, i kept diving, couldnt understand it, i was on my way home and this thread popped in my head, like a freakin mallet hitting a gong, i woke up. duh! wish i would have been quicker might have saved my rear body post

If you took the time to look at commercially available conversions, the majority offer the mechanical braking as an option.

The Tekno Revo conversion uses the existing brakes as do alot of their buggy & truggy conversions.
This is directly from their site..........
Uses stock mechanical brakes so you can tune front/rear brake bias if using the center differential kit. This results in much more predictable braking and less heat generation compared to using 'motor braking', not to mention it will save your transmission from unneeded stress.

The only good thing those rocks are for is to throw at your head.

Look before opening mouth.

You may want to heed your own advise, my friend. Of these "commercially available conversions" you mention - I would bet that nobody offers the range of conversion parts that RC-Monster does - nobody is even close to the number of vehicle conversion parts we offer(so I would say we are the majority) - and it is true that most or all of our mounts offer an allotment for mechanical brakes....BUT the majority use motor braking and not mechanical braking - and by a longshot.
Your quote of mechanical braking being more predictable isn't true, either - the fact is that electric motor braking will be more consistent - no mechanical parts to wear or cause fade. Electric braking can also be tuned for far more braking force vs. mechanical brakes. Don't confuse predictable or tunable handling with predictable braking - the electric brakes will be the same every time without fading(consistent and therefore predictable).
Using pure mechanical brakes will lower motor temps, and having the opportunity to adjust brake bias can have its tuning benefits as well - along with its detriments. I would say it is largely user preference - the mechanical brake's ability to tune bias can improve handling at the expense of more weight, complexity and work to get set up(worthwhile tradeoff to some, but certainly not the majority). Any "commercial" electric vehicle on the market uses motor braking - the idea of mechanical brakes was born because nitro vehicles have to use mechanical brakes - one benefit of electric is the simplicity - brakes come with the power system.

Basically, there is no "right" or "wrong" way to get it done, but simply different strategies and preferences that vary from user to user. There are far more bashers in the hobby than there are racers, and a basher will almost always prefer the simple electric motor braking - easy to install, easy to convert their vehicle and nothing to really tune - plug and play convenience at its best. A racer is far more likely to experiment with mechanical braking to tune front/rear bias, but this will be a matter of preference as well. Some like it, some don't. There is no right or wrong, but simply differing opinions and preferences. Personally, I think the "best" way to do it may be a hybrid setup - a small servo to mechanically brake the rear only, and motor braking for the center diff itself - a small servo can be used for minimal weight, and front/rear bias can be effectively tuned on your radio(with channel mixing). The tunability of pure mechanical brakes, but with lower weight, increased simplicity(mechanically) and easier "right now" tuning through the radio. I use motor braking on most of my stuff, though - the fact is driving electric vehicles is different than driving nitro vehicles, and I rather enjoy the pure simplicity of this strategy(and on about 95% of the tracks I race on, I haven't felt disadvantaged without the front/rear bias tunability) - I won't force my opinions on anyone else, though - or bother calling names and throwing stones at those who disagree.

Hey Daf,
Its been a while, nice to see you online
I have been racing my MBX5T with a NEU 1515 2Y for some time and I really don't notice much, if any, "drag brake" when jumping. I also run a 6 Pole Mega motor and I don't notice much, if any, "drag brake" on that truck either.

As for Brake setups, personally I would rather use motor braking on all my vehicles but I've found that cars with center diff's perform much better for me with brake bias (mostly rear only). Also, the Tekno guys use the 2 speed Revo trans which requires mech brakes due to the oneway bearing so the advantages they list aren't option's but requirements.

I like Mikes Hybrid brake suggestion using a very small, light weight servo for rear brakes only and motor brakes for the remainng percentage of braking power you desire.
