Hey, they made me learn this shit in school, I might as well use it for this as I certainly don't use it for my job.
RC Tech needs more posts like this. Very good insight, thank you.

I use the exact same antenna "bundling" technique. Is there a way of cancelling out this effect? Such as, if I run the end of the antenna through the wrapped antenna would that cancel it out?

Like I said, its not a big deal unless you hit the wrong combo right on the head of the nail, so don't worry, its biggest drawback would be limiting your range, but isn't a problem if you just run indoors and never have the car more than a hundred yards from you. Definitely not a suggested setup for airplanes.

Here is the best I could do. Didn't come out as well as I had hoped . I ended up having to add 45g of weight to the outside edge to get the car to balance and the car is still significantly lighter than my TC6.1 was (where I only had to add 30g).

Wires in the servo we re-routed out the other side and switched to black wire. Same for the Tekin RS. Replaced the PT wire with black. Painted the Seis fan wires black.

Also removed the nub since someone gave me a hard time earlier . Now to finish setting it up and paint a body so I can race tomorrow.

Run your power wires over the top deck, and push the battery under the top deck, this will let you use a lot less weight to balance, then just add what you need to make min down the center. Put the sies fan in front of the motor below the tekin, this will redistribute its weight a bit to help.


I only have 10g on the left side for balance, but the LRP is a little heavier than a tekin.

Do I just rely on tape to hold in place or how do I keep it from running into the belt? Maybe I missed something.

If you use an xray center weight, that works, I have screws in the center holes, and dremeled plastic nuts to act as stoppers. You could shoo goo a small piece of carbon or plastic as well.

Do you prefer that look over moving your electronics in closer to the middle and placing those weights flat on the chassis? You could cover them with a CF sticker. Or what about stacking them up behind your servo on their side? It would be kind of like having a normal length servo, but you've got the room.

I've never seen a competitive car with weight hanging off the side like that. Never.

I planned to lay them flat between the motor and esc but couldn't get it to balance there without making the car overweight. Also you've seen plenty of competitive cars with weight hanging off the side. Just look at the battery side.

Esc shield would make more sense to me. Much more money to get smashed. Doesnt seem like a worthwhile purchuse for onroad cars though.
