Thank you for viewing! This is a Kyosho Mini Servo KS3031-04M, all-metal gear specification, product number 82278. Purchased new a few months ago. It is a fully functional item, used a few times. This is being sold to clear out inventory. Here are the specifications: https://rc.kyosho.com/ja/82278.html?srsltid=AfmBOooRmDCB52CtQgvx540GQvbenM_5vCW9swlBGoGrtNvQ51TujKDj Thank you for your consideration. Note: I don't think the item itself smells, but please refrain from purchasing if you are concerned about general household odors.
