Due to quarantine shutting down the local race track I decided to jump into crawlers with my 8yo son for playing around the house. I chose the Sport Kit for the value and I also had all the electronics to get it going.
I knew the tires came unglued so I picked up some cheap beadlocks from Amazon.
The build went very smooth and the instructions were good enough that my boy could do a lot of it on his own.
We used some paint we had already. Tamiya PS-17 Metallic Green and PS-9 Gunmetal Gray.
Electronics I used from the parts bin:
Radio - Tactic TTX300 Tx/Rx
ESC - HW Quicrun 1060
Motor - HPI Gt550
Servo - DS3218 20kg
Right out of the box we were amazed at how capable the truck was on the wood pile out back. The HPI motor did pretty good and I even had a 16T pinion to gear it down a tad just after our initial running. The motor would run pretty hot and I figured it was tired (spent its former life in a hopped up powerwheels in my sons younger days) But I realize now that a lot of the heat and poor run time was due to it being standard rotation.
I didn’t want to be dead in the water if we let all the smoke out of the HPI so I ordered a Holmes Hobbies 550 Crawlmaster Sport 15T. Once I tried that guy out the HPI was put back in the parts bin! Amazing how strong it is, stays cool, and has great runtimes.
