The backdraft 8e, earthquake 8E and aftershock 8e are all fine.
The monsoon xtr and hurricane xtr are solid too.
I'd look into the new 1/5th. scale electrics as those should be hot movers when released.
The micros look like a fail to me, but the crawlers are all solid, just have better servos on hand for customers. Extra batteries and radio parts as well. Redcat will drop ship many items to the customer direct so look into that as well. Good luck, their brand has some image repair to be done.
The entry level 1/10 nitros may be better now, but they used to be awful. I have really good luck with their 8th. scales owned 2.
