Hi guys,
So, I've gotten most of my from-scratch MRS4 set to go at this point. The motor I picked up for it is
this one (Team Orion Slo-Max 300 Avionics motor). It seemed like a decent motor for the price, with caps already installed, because I'm lazy like that.
Next up was the batteries, thanks to
Blind; a six-cell 1400mAh NiMH bullet-pack setup, which proved to be a perfect fit for the Penguin 3500LM chassis battery trays.
The servo I picked was a little smaller than most people seem to go with on an MRS4; an HS-65MG. The only problem I have with this servo is the fact that none of the usual servo savers fit.

It has plenty of torque for it's size, though, and fits like a glove mounted vertically.
Finally, the receiver: Spektrum SR3500. This thing is practically microscopic. Fantastic stuff.
So, with all of the easy stuff out of the way...I have no clue about ESCs.

What do you like, and why?
(This has been quite a job, trying to find any parts for a Micro RS4. eBay has definitely been my friend lately.)
