RC explicado: aceite o grasa en diferenciales, y por que?

Today we created a new list that will be called RC Explained with short videos explaining things about RC operation in a simple and easy way. I hope you like it. Upon request I leave you the link of the store where I buy the differential oil. Even so, I do not know if the shipping is profitable or you can look at your local store. https://www.hobbyplanet.es/es/ We also leave you the link to the Goldbat lipo guard bags in case you are interested. https://www.amazon.es/GOLDBAT-explosi... = 1 & keywords = Lipo + Safe + Safe & qid = 1622723547 & sr = 8-4
