Machete Updates
This page was created to keep everyone updated on the 'potential issues' and corrective measures Redcat has taken with regards to the Machete 4S and 6S Monster Trucks
Machete Update (4/19/2023)
Redcat is excited to announce that both the 4S and 6S Machete Monster Trucks are back in stock and available for purchase and the upgraded parts are now included in the box and can be installed when / if needed.
Upper Arms - Four updated upper arms are now included, offering increased strength compared to the ones currently installed on your Machete. You may choose to install them now or save them for future use.
Shock Rod Ends & Center Drive Shafts - These parts are intended as spare parts in case you experience any issues with your Machete. While we do not anticipate many customers will require them, we have included them as a precautionary measure.
4S Series Cable Adapter - If you purchased a Machete 4S, a series adapter has been included to enable the use of two 2S batteries in series as an option.
Machete Update (4/3/2023)
We appreciate your patience as we addressed potential concerns with the initial release of the Machete. We are pleased to inform you, that we have shipped out the updated Machete parts to all customers who initially purchased and chose to wait for the updated parts to be made available.
Moving forward the below mentioned updated parts will be included in the box for customers to install as needed. Redcat will include these parts as standard installed parts with the next production run.
How to install updated / upgraded Machete replacement parts. In this video we talk about the updates that have been made to the Machete 4S & 6S monster trucks. We also show how to install the new upper suspension arms as well as the lower shock ends. Thank you for your support and understanding!

Machete Update (3/16/2023)
We would like to call out two YouTubers who played a pivotal role in identifying the potential issues.
- DO RC with YouTube channel https://www.youtube.com/@DoRC
- Matt’s MotoWoRX with YouTube channel https://www.youtube.com/@MattsMotoWoRX
Please check out both of these YouTube channels as these guys have great content.
The design of the Machete started early 2022, and we put the Machete through over 4 months of rigorous testing. In our tests, we did not experience the 3 issues which we will mention below.
After a product design is finalized by Redcat, tooling/mold making begins. Test vehicles are produced from the tooling and sent to us for review and testing. These test vehicles are not assembled by the factory assembly line, but are instead assembled by the experienced engineers at the factory to our precise specifications. Once we have completed testing and made any necessary changes, we approve the production vehicle design, an order is placed, and the factories produce vehicles to fulfill the order on their assembly line.
With new vehicles, factories have a learning curve on their assembly lines, in some cases the factory can assemble something incorrectly in the process, which is not easily detected by the quality control process.
The Machete has 2 potential assembly issues, 1 design concern that is also being addressed, and we are addressing a missing part that was to be included with the Machete 4S.
Upper Arms (potential problem)
Some Machete owners have reported breakage on their front upper arms. The upper arms are 4 pieces. They include a left & right plastic part, an aluminum center part, and a steel grub screw to hold the pieces together.
During assembly, if the grub screw is not correctly centered within the 2 plastic end pieces, a weakness in the part can occur and cause breakage.
We have spot checked a large batch of Machetes that we have in stock and found less than 2% that had this assembly issue where the grub screw was not centered.
Out of an abundance of caution we have redesigned this part, greatly increasing the length of the grub screw as pictured below. This ensures that the screw cannot be installed off center.
All Machete owners will receive a full set of 4 upper arms. (2 front & 2 rear)
The top image shows the current grub screw length. If this was not centered correctly during assembly, a weak point would occur.
The bottom image is the revised part that will be sent out to all Machete owners.
Plastic Shock Ends (potential problem)
Some Machete owners have experienced shock ends that were over-tightened at the factory which resulted in the threads in the shock end plastic part being stripped out.
We do not expect this to be an issue on many vehicles but we recommend that you make sure that your shock end is firmly attached to the shock shaft.
We will include 4 shock ends to all Machete owners.
Center Drive Shafts (Addressing issue)
A Machete owner reported an issue where the center drive shafts started to twist after “locking” the differential.
We tested the Machete on 4S and 6S for over 4 months prior to moving to volume production, and we did not experience any issues with twisting driveshafts during our tests.
Since this issue was reported we have tested multiple vehicles with different differential oil viscosities. We did not experience any issues until attempting to “lock” the center differential using extremely thick oil.
The differentials are meant to be tuned, and we understand that owners will modify their vehicles to their liking, however all vehicles have design limitations that can be surpassed through modifications. Once these design limitations have been hit, parts can begin to fail in ways the designers did not anticipate.
We have modified the current drive shaft to increase its torsional strength and all Machete owners will receive these new updated parts. We do not believe that many users will ever need to replace their original center drive shafts, but this tweak will help expand the amount of modification the vehicle can handle before the user experiences an issue.
The current center drive shaft is pictured above (left). You will see that the center hole will be removed on the right image which will increase the amount of torque the drive shaft can handle.
We have read comments where some people want to put an 8S power system in the Machete and we understand users enjoy modifying cars beyond their designed limits. Please use caution when making extreme modifications.
We are also designing full steel center drive shafts as an upgrade part which will be available at a later date.
Battery Adapter (Machete 4S)
The Machete 4S should have included an XT90 series adapter to allow users to run two 2S batteries instead of one 4S battery if they choose.
All Machete 4S owners will receive an adapter.
Our number one goal is to make sure that all current Machete owners receive their new parts as soon as possible.
We expect to start shipping the above parts by the end of March.
At a later date we will announce when Machetes will be available from Redcat but we expect that shipments will begin again by the middle of April.
We greatly appreciate the support we have received from many customers. We were overwhelmed by the positive remarks in how we are taking care of these concerns, and we will strive to continue providing you the best customer service in the industry.
Machete Update (3/13/2023)
We regret to inform you that the New Redcat Machete 4S and 6S are currently unavailable due to potential manufacturing issues that were not found during testing but were discovered with the initial shipment arriving in the USA.
We understand that this news is disappointing and we want to assure you that we are working diligently with our factory to resolve these issues as soon as possible. We will keep you informed of any updates as soon as they become available.
For customers who have already purchased the Machete, please reach out to Redcat so we can help you. We are offering two options. You can contact Redcat to return your Machete for a full refund, or if you prefer to wait for the updated parts, Redcat will send them to you as soon as they are available, free of charge. In addition, we will also provide you with a $50.00 Gift Card to be used towards any future purchases on the Redcat website as a token of our appreciation for your patience.
We understand that you may have questions about the time frame for the updated parts. We will have a better understanding of the situation later this week and expect that the parts will be available in less than three weeks.
We apologize for any inconvenience this may cause and appreciate your understanding as we work to resolve these issues. At Redcat, we take pride in delivering quality products and we will continue to do everything possible to ensure that our customers are satisfied with their purchases.
Thank you for your continued support.
Regards,
