Hey all,
I'm new to the surface hobby, though been flying RC heli's (and some planks) for about 11 years now, so reasonably well versed in the basics. That said, I've now acquired (and built) the SCX10 III and the TRX-4 kits, and seem to have caught the bug! I've got the Capra kit sitting here ready to build as well, and wanted to run through my electronics and see if I'm on right track...
First off, I've got more reading to do when it comes to brushed motors and crawler gearing, as my experience is exclusively brushless thus far. The Capra is the first kit where I'm using my own selection of electronics (I'm using the same electronics in my SCX10 that came in the RTR version for now) and following some other's footsteps I've opted to go with the Holmes 500V3 servo, Hobbywing 1080, and Holmes Crawlmaster Sport 16T. I also picked up a Reedy Radon in 16T as well, may use that in a different build.
I grabbed an 11T pinion for the Capra as well, as it seems stock pinion is bit much at 14T for these builds. Does that seem appropriate? Any great resources on understanding crawler motors and gearing? Like I said, I'm used to calculating headspeed on heli's with a single main gear and pinion, as well as kv and Lipo cell count, so this is all new to me...
That said, I would like to try a brushless system (likely a Spektrum as I like the telemetry and have a DX5 Pro) but would need to figure out the ins/outs of gearing to make a proper selection on kv rating etc.
I'm running 3S on all three trucks, so with that in mind, is my selection appropriate for a "budget" esc/motor setup on the Capra?
Appreciate any and all input, and if someone has a great resource that could help me better understand cralwer specific brushed/brushless motors I'd really appreciate it - as I'd imagine I'll start playing around with brushless setups sooner rather than later, for now I just wanted to get something that would get me started!
Anyway, having a blast toying with these trucks thus far, it's refreshing to have something that moves at a slower pace as opposed to a 700 size heli that could potentially lob my head clean off if I'm not careful ;-)
Edit - here's a motor I'm interested in https://beachrc.com/spektrum-firma-2800kv-brushless-sensored-crawler-motor/
Not sure it'll fit, as it seems it's a bit limited. Length is listed as 58mm, and I've seen mention of 53 being about max, though I'm not sure if that's just the can length, or can + shaft etc. Worst case, I'll could toss it in the SCX10.3 instead if I ran into issues. Seems 2800kv would be suitable for either Capra or SCX. Thoughts?
