Note: The Mamba-25 has been replaced by the Sidewinder Micro. All FAQ items below are applicable to both products.
| 1. My Mamba-25 18th scale system seems like it has turbo lag where it takes awhile to get going, then takes off. Why is that?
The most common cause of lag, or lack of initial torque, with a Mamba-25 is inadequate batteries and/or inadequate connectors or too small a wire on the battery pack. For a brief period when starting up, the Mamba motor will want to draw almost 100 amps! Resistance from the original connectors, or low discharge performance battery packs will not be able to supply the current for “better than stock” performance. We recommend Deans Ultra plugs between the battery and the ESC, and 16 gauge wire from the battery packs (same size as on the controller). The best NiMH cells on the market are IB1200s, IB1400s, and GP1100s, regardless of pack manufacturer. There are a lot of 1100-1400mah cells out there that vary widely in capability, but the IB (Intellect Battery) and GP (Gold Peak) cells are by far the best. Right now, Lipo packs also vary widely in discharge ability. Give us a call if you'd like specific lipo pack recommendations for your system and vehicle.

| 2. My Competition X Mamba system in my Mini-T keeps flipping the truck over if I give it too much throttle. When I can keep it rubber side down, it's so fast that I keep hitting things. What's going on?
Congratulations! Perfectly working system!

| 3. I’ve heard you released new software for the Mamba-25 1/18th scale systems that helps with cogging issues. Is this true, and if so, which version do I download to my Mamba-25 controller?
You heard correctly. Our new version 1.05 Mamba software is smoother than ever and eliminates virtually all cogging issues. You will need a Castle Link in order to load the software to the controller (or you can send it in to us to have it upgraded). If you’re still experiencing cogging after loading this software, chances are the problem lies elsewhere in the system.

| 4. Should I grind a flat spot on my Mamba motor shaft to help hold the pinion on?
No!!! Grinding a flat spot on the shaft weakens it and makes it prone to snapping. Most importantly it VOIDS YOUR WARRANTY!!! A better method for attaching your pinion is to use green loctite (RC™ 609 formula). This formula is made specifically for attaching pinions to motor shafts, and works so well you don’t even have to use a set screw. To remove the pinion simply heat it up with a small torch or lighter (preferably torch), and it will pop right off.

| 5. The shaft on my Mamba motor snapped while driving. What should I do?
If you’re within the warranty period (1 year from date of purchase), send the motor in with a copy of your receipt and we’ll replace it free of charge. If you’re out of warranty, please see the flat rate repair fee chart located on the General FAQ page.
