Currently running a 6.5 and I love it in my wheeler.
Looks like plenty of room for lots of different motors and esc's when running shorty packs. A tekin hd 4300 will be a little heavier with an insane amount of torque.If you're just having fun, try it and see if it works.
The traction along with big motors caused most other cars to break at some point at the Worlds (but the D413 held up fine). Installing a Tekin hd 4300, and putting it in the hands of someone other than Ty seems like it would be good durability testing
I was just joking about pulling the 4300 out of my sct410, it's a ton of power for an sct, would nuts in a little buggy. Unfortunately don't have the skills of Tessman so I'll be shopping for milder setup. Our indoor track is about 70'x30' so I don't need a ton of power. Thanks for the info! I guess all the dumb questions have been ask and answered over and over so I'll patiently wait until they are ready for sale. OH Santa send me a ET48 too please! I only race Tekno and Hot Bodies so I'm deserving! LOL
