1800kv vs the 2300kv for redcat gen 8?

Depends on if you’re more into crawling or trailing. If you’re crawling I’d say save the money and get the 1800kv SE, trailing go with the faster 2300kv Pro. Having both, I can say there’s not a huge difference. I do love my Pro 2300kv. But I also run the 1800kv Fusion SE’s in a couple of my trucks and as far as crawling goes, they’re just as good and are almost half the price. The SE comes in 2 variants, 1200kv and 1800kv. If you decide to go the SE route, id say go with the 1800 and change your pinion size to get the speed to torque ratio that you’re looking for. I run the 1800 in my Redcat Gen7 with stock pinion and it’s fast enough to trail with.

which is better the combo or 2 in 1 technology ?

The 2 in 1 fusions are great. I love how it simplifies the layout and really cleans up the chassis as there’s no esc to mount.

How will this work without programming card vs brushed stock trx4 motor?

The motor is set up with pretty much everything in the middle. Drag brake is set at 5/10 which is meant for roughly a 12lb rig, decelerating in set 3/6 but is kinda fast but not fast enough to start breaking stuff. I personally have not used it in a trx4 only scx10’s but way more power then a brushed motor, it has a crawl feature that will maintain the speed over an obstacle, it does not cog like unsensored motors. The one thing to look at is clearance for the motor, since it is a two in one which makes it longer (58mm) so make sure it can fit in the cassis.
