The internal bec will do just fine, and the esc will take it aswell as the motors, just not very long. 3s will do what you need well!

hey john do the waterproof br-xl's still look like this (minus bullet connectors of course). or are they being waterproofed and then plastic case installed over top.

They are now epoxied inside the black case. It is lighter and easier this way.

thank you !
I just picked one up from a guy who runs a hobbyshop and he said it was not the waterproof version. so it came today and the heatsnik has some clear glossiness to it and the board seems pretty shiny from what i can see thru the case. is the waterproof coating super thin on these things now. I would have not had a thought about it being waterproof but when i saw the clear stuff on edges of heatsink it made me wonder if it is waterproofed already.

sorry can't seem to get a good pic of it

easiest to look at the leds. Conformal coating of the regular units can also get on the heatsinks.

An updated mini design has just been finished and will start production right away. The first batch will be small to ensure there are no problems with production, then we will start regular production volumes.

New specs:

1.1x1.1x0.138" (28x28x3.5mm) ESC size, no wires
0.315" (8mm) diameter capacitor
1 amp BEC for internal power or RX power only
1.2mOhm ON resistance (same as big brother)
slim RX wire
Stackable design



Future tweaks to the BRXL line include an enhanced throttle mode with active motor speed modulation. It will put an end to rollaways and LOCK motor speed into the range you specify. Even rolling downhill, if you give 1% throttle the motor will not be able to coast faster with Active Modulation enabled.

What type if epoxy do you guys use? I'm going to try my hand on my ae2 esc and my sidewinder

It depends on the situation. Conformal coating, electronic safe silicon (non acidic outgassing), and epoxy potting are the three main types we use. For the SW and AE you will have the easiest time with a conformal coat applied on in 3 to 4 layers. It is one part, dries via air, and can be brush applied. A google search shows up many options for purchase. We use Dow Corning, Henkel, and 3M products on the majority.

How do you do it fill up a small small container and dip it in it, or what?

It depends on how you want to do it, there is no wrong way. The easiest method for "at home" is with a brush or from an aerosol can. Lay down wax paper so things don't stick. Less waste than dipping since there isn't a dipping container, as most coatings don't have a wide mouth lid until gallon sized.

I don't have an exact timeline for the addition, it is the next engineering task. The method I will be using for motor control has not been used in RC before, and rightfully so because it depresses the motor speed at low RPM and makes the throttle more sensitive. Great for competitive rock crawling and robotics, horrible for racing.

john,
is this purely a software change or will this only be available on a newer version of the esc with hardware needing to be changed. In other words will past br-xl owners simply be able to upgrade firmware? thanks and sounds like an awesome awesome tool to have in the crawling belt
