The Eagle Turbo Chassis version is ready here are a couple of pics. I have not listed it on the website yet. I wanted Nitro Forum to have first look.

Looking killer, looks like I'll be trying one of those frame motor winds to put in one of those soon...

Here are a couple of pics of shunted brushes I am building for the Wolverine, sjracer ride. I really don't have time to do a how to, but I will share this. Drill a hole in the brush. Then take your shunt install in the hole flush with top side. Then with brush setting on top and shunt sticking straight up take some Loctite Super Glue GEL CONTROL and coat the bottom of brush and base of shunt. Let it dry. The shunt is now installed. Here is the best part the Super Glue will INSULATE the bottom of the brush from the spring. To make sure it worked take your ohm meter and check for continuity. Put one of your probes on top side of brush and the other on the shunt. You should have an audible sound from your meter. Now do it again only have the probe touch the base of the brush being careful not to touch the shunt. The meter should make no sound. The brush spring is now insulated from the brush. However you must be careful that the shunt does not touch the spring it is not insulated. BSRT use to sell shunt wire that was super flexible and insulated. That would be perfect.

Robert thanks for posting how you did the shunted brush. I got a couple of questions. Do you drill the hole all the way through ? If so does that hole in the brush goof up the contact to the com plate ? And if the glue is a insulator then how does the shunt make contact with the brush ? I Love this idea and I’m going to give it a try but I had some stupid stuff floating about in my head. And the only way for me to learn is to ask stupid questions😁

No, the shunt fills the hole and wears down with the brush. And if the glue is an insulator then how does the shunt make contact with the brush? That is why I only use Loctite Super Glue Gel Control. It does not soak through the shunt. It only coats the outside of the shunt. The bottom or base of the brush where the shunt enters the brush is the only part coated with the Gel. That keeps the shunt in place.

Nice tip Robert. Scale auto still sells that silver shunt wire. Part # HT125.

Thanks Robert going to give it a try. Got some of that Loctite Gel coming tomorrow.

I'm thinking you are soldering, but I wanted to ask to make sure.

I am terminating the shunt with a micro screw. The hole you drill in the tab to stiffen the tab remember. I use it to attach the shunt. I believe the length is critical and the flexibility of the shunt. I want to use smaller shunt wire. The BSRT shunt is next on my list.

Sam ran a shunted brush setup years ago on his FED's. I have not had to do that on my builds. I have found that when the arms go below 3ohm it seems to be a problem with cooking the springs. Over 3ohm I have not experienced that problem. I will be soldering the termination on mine. I will post what I do and how it works out. I think I have some of the BSRT insulated shunt wire but the insulation is too thick for use on this. Not sure if it is the same wire you are talking about. Thanks again!

BSRT makes a non insulated shunt wire. It is only .015 thick.
