Pinion / spur suhe. Näiteks 20T pinion ja 80T spur = 4:1 ratio (kerge kiirendus, madal tippkiirus). 30T / 80T = 2.67:1 (parem tippkiirus, aeglane kiirendus). Vali raja-tüübile.
RC pinion-hammasrattad — 48dp, mod 0.6, mod 1.0. Erinev hammaste arv mootori-poolele.

48dp = USA standard (1:10). Mod 0.6 = Euroopa standard (kasutab metric pitch). Hambad EI sobi omavahel — eraldi spur ja pinion. Iga chassis on spetsiifiline.
Suurem pinion (rohkem hambaid) annab kõrgemat tippkiirust, kuid madalamat kiirendust ja kõrgemat mootori-temperatuuri. Vali rajale: lühike tehniline rada = väikseim pinion. Pikkade sirgega rada = suurem pinion.
Teras: vastupidavam (sõidu-päevi 50+ kuluvuseta). Alumiinium: kergem, kuid kulub kiiremini (alumiiniumi pinion 1:8 buggyl võib kestada 5-10 sõidupäeva). Soovitame teraspinion.
Kuluvus märgib: hambad muutuvad ümaramaks, gear-mesh ebaregulaarne, müra. Teras-pinion kestab 30-50+ sõidupäeva. Alumiinium 5-15. Kontrolli iga 10 sõidupäeva järel.
