RER11399 vs RER30584: Which Redcat Part Fits Your Build?
By Redcat Racing | Published: 2026-11-04
Category: 比較
RER11399 is a 550 brushed motor for several Everest and Gen vehicles; RER30584 is a bronze-finish aluminum Panhard mount for Ascent models. Here is how to choose.
Quick answer
Choose RER11399 if your Redcat vehicle needs a 550-size 17-turn brushed motor and is listed as compatible; choose RER30584 if you need an aluminum Panhard mount for an Ascent Fusion or Everest Ascent. They serve different systems, so the decision is about function and fitment, not price.
Function: motor vs suspension mount
RER11399 is a drive-system part: a 550 brushed motor with a 17-turn winding. RER30584 is a chassis part: a single Panhard mount made from aluminum with a bronze finish. One makes the vehicle move; the other locates the Panhard bar in the suspension. That means they are not interchangeable alternatives, and you should not compare them as if one could substitute for the other.
Because they belong to different systems, the practical question is which system needs attention. If the vehicle has no drive or the motor is worn, RER11399 is the relevant part. If the front axle location or Panhard bar mounting is damaged or being upgraded, RER30584 is the relevant part.
Fitment lists differ and are not universal
The supplied fitment for RER11399 covers Everest Gen7 Pro, Everest Gen7 Sport, Gen9, Gen8 Scout II, and Gen8 V2. The supplied fitment for RER30584 covers ASCENT FUSION and EVEREST ASCENT. These lists do not overlap in the catalog facts, so check your exact model before ordering either part.
If your vehicle is not on the relevant list, do not assume it will fit. The catalog does not provide dimensions, mounting patterns, or winding alternatives, so there is no safe way to infer compatibility beyond the stated models.
Stock replacement vs hop-up
RER11399 is listed as a direct replacement part, which suits a straight repair when the original motor has failed. RER30584 is listed under both Hop Ups and Spare Parts, so it can serve as a replacement or as an upgrade part. The bronze-finish aluminum construction is the catalog description; no weight, strength, or performance claims are supplied, so treat the material as a specification rather than a promise of a handling change.
Trade-offs to weigh before buying
- Repair urgency vs upgrade intent: If the vehicle will not drive, RER11399 addresses the motor circuit; if the front suspension mount is damaged or you are upgrading hardware, RER30584 addresses that. Buying the wrong system leaves the original problem unsolved. Diagnose the failed system before ordering.
- Fitment list coverage: RER11399 covers Everest Gen7 Pro, Everest Gen7 Sport, Gen9, Gen8 Scout II, and Gen8 V2. RER30584 covers ASCENT FUSION and EVEREST ASCENT. Check your model against the correct list rather than assuming a shared chassis. A part that fits one Redcat model may not fit another.
- Motor specification lock-in: RER11399 is a 17-turn 550 brushed motor. The catalog does not list alternative turn counts or brushless options, so if you want a different motor specification, this part is not a tuning choice. Use RER11399 as a like-for-like replacement, not a performance experiment.
- Mount material and finish: RER30584 is aluminum with a bronze finish. The catalog gives no strength or geometry data, so choose it for the stated material and fitment rather than for an unverified performance gain. Treat the bronze aluminum as a specification, not a guarantee of handling change.
Product facts
- RER11399: 550 brushed motor with a 17-turn winding, sold as a single unit. It is a direct replacement for the listed Everest and Gen vehicles, so match the motor size and turn count to your original before installing.
RER11399 - RER30584: Aluminum Panhard mount with a bronze finish, sold as one piece and listed as both a hop-up and a spare part. It can replace a damaged mount or serve as an upgrade on compatible Ascent vehicles, but the catalog does not state dimensions, so confirm the model fitment first.
RER30584
Which part is right for you?
Best for
- Owners of Everest Gen7 Pro, Gen7 Sport, Gen9, Gen8 Scout II, or Gen8 V2 who need a 550 17-turn brushed motor replacement
- Owners of Ascent Fusion or Everest Ascent who need an aluminum Panhard mount as a spare or hop-up
Not for
- Vehicles not listed in the relevant fitment list
- Buyers seeking a brushless motor or a different turn count, since RER11399 is a fixed 17-turn brushed part
- Builds needing a Panhard mount for a model outside Ascent Fusion or Everest Ascent
