Losi Self-Stick Chassis Weight 3 oz LOSA99201 Electric Car/Truck Option Parts

I use these weights for RC planes. Make sure the surface to be used is oil free. These weights are easy to use and effective.

Stuck on well to max out weight! Easy peasy.

For someone who is not very good at drilling holes to add weights to my son’s pinewood derby car, this was a v simple and good alternative. I liked that it was in small squares so I could just cut it and distribute the weight. Also managed to restick well when I pulled it off to rearrange it.

Perfect for Pinewood Derby. East for cub scouts to install themselves even

Exactly what I needed for our pinewood derby car. I'll purchased again next year.

We got started a little later on our derby cars than we would have like to and since the plan was for everyone to build a car we had a decent amount of work to do. I decided to axe mine all together and focus on the kid's cars. My husband however still wanted to do his. We ended up getting the kids finished around 530 the day before the race. My husband at that point however had only cut out his car. He then flew through painting and trying to finish it and had it now been for these self stick weights I don't know if he would have had anything worth racing. He placed 2nd in his class and 3rd overall. Not a bad showing thanks to these weights.

Was the perfect way to add extra weight to my kids pinewood derby cars. We could even paint it to match color schemes. Really liked how it was self adhesive and it worked better than others we tried.

These small weights with the self adhesive backing make them very easy to use in a multitude of applications. Recommended for the price. I ended up buying two packages.
