ESC for Super Avante?

This is my first array into brushless and I really didn't want to buy twice. I figured I could always limit the power? Now I just need to decide on what LiPo or LiFe to buy for it.

Are you going to do a build thread? Hope so!

5.5T is really a lot of power. Even pro drivers in big races rarely use anything bigger than that on the best 4WD chassis. Definitely much more power than I would trust a non-TRF Tamiya kit with, personally. But yes, you can reduce power - to a certain degree. Mostly you can reduce the RPM, but torque...

I've gone for a HobbyWing XR10 Pro Elite along with a XeRun 5.5T. Hopefully all will fit and work out ok.

Sweet Lord that will be fast…….

I’d start somewhere around the 10.5-13.5t mark if it’s your first brushless tbh.

So would I, to be honest. If you have never had any brushless experience before, you are in for quite a shock...

If he is lucky, it will be only fast - it might also be over very quickly. I doubt the car has been constructed with this kind of power in mind. Plus, I don't know how adaptable the gearing is, but if it is too long, you might even damage that motor.

Im used to running the Super Stock BZ which I believe is similar to a 13.5T. So my thinking was if going brushless then I didn’t want something similar - but faster. And looking at HobbyWings spec. sheet… this seemed to be the way to go.

At least the TD4 will have spares available

Just as long as you don't put additional timing in your ESC settings like people do in racing. That's what would make the car really fast.

Here's a youtube-video of the German 4WD Buggy championships from this year, hosted by our club:

These cars also mostly use 5.5T motors - and by the way, that back straight is 50m (~165ft) long. See for yourself what you're up to.

5.5t will be fine unless you hit something

 

Will certainly test the gearboxes. Apparently you can upgrade the bevels to add some more heft to it.

I certainly wouldn't say a 5.5 won't work or is the wrong decision, nobody knows until we actually get to see, build and use the vehicle. What I can say from experience, I have a powerful 6.5 in my TRF511u, is that a 5.5 will stress everything. Motor mount, gears, diffs, outdrives, dogbones/uj's, axles, hubs, tyres and even the glue you use to keep the tyres on. Anything plastic will break. Having said that, if it stays together and you have enough space (solid objects are a killer with that amount of power), then it will be a total blast!

Do be aware though with more power comes more air and harder landings and you'll 1000000% need a slipper, lots of clutch pads and at least a ball diff in the rear (drivetrain seems to directly link front and rear drive so no double slipper option) with very good, probably ceramic or tungsten, thrust balls (wet, sealed gear diff up front will be fine). Prepare all that stuff before you commence the build. Get the diff or the slipper wrong and it will take less than 60 seconds to destroy them with that amount of power (ask me how I know!). 

And be sure to make videos, lots of videos. 💪
