Exotek have introduced rear brass weight set for the Tekno EB410. Made of brass and black coated to reduce corrosion, this weight set is designed to easily bolt on to the rear of the EB410 with an extra low profile. The main weight is 40gr and included are two add on 8gr weights (16gr total add on plus the 40gr main weight) so that you can tune the rear weight of your buggy as needed. The weight set is also slightly angled off of the chassis to maintain chassis flex. Sold separately are additional 8gr weights so that you can easily add extra grams if needed.
