With regards to gearing, I can try to help if you need a starting point, I just need to know what motor is in there and the number of teeth on the spur.
The futaba 9551 is my favourite servo, great choice

Thanks for the kind words. It has been fun and gruelling build at the same time. The time in shipping to receive parts added considerable time to the build. The last package of parts took a month to arrive.
Is it really an SRT.... or is it just a glorified Rustler.... or does it lie somewhere in between, lol.
The motor is a Hobbywing G4 17.5T which I set the timing to a semi aggressive 5.5 amps. The spur gear is 76t and the pinion 23t which is a conservative FDR of 8.99 to let the motor rev out a bit if I went a bit too aggressive on the timing. If it doesn't get too hot I can gear up and/or add more timing, or if it gets too hot I can reduce timing. I figured that would be a reasonable starting point to try, at least in my mind anyways, lol.
