87/23 with a 10.5 seems a little under geared to me..unless you're adding a little esc timing.
partially cuz i dk what i'm doing lol so for now it just works, but i can always drop to an 84 spur and then go up in pinion, there physically is no more room for a larger pinion with the 87 spur. but yes I was running some timing...till my esc decided to go down the crapshoot.
