FAQ

Is the Overthrow safe for kids and beginners?

Yes. The Overthrow’s flipper is a non-destructive weapon — it launches opponents into the air rather than damaging them, so there’s no spinning blade or disc to manage. It doesn’t need a specialized arena, making it a great fit for classrooms, camps, and clubs.

Presoldered or unsoldered — which build should I choose?

Presoldered is ready to wire up and run with minimal soldering — a good fit if you want to get building fast or you’re newer to electronics. Unsoldered gives more advanced builders full control over wiring, including adding their own weapon system down the road. Full disclosure: soldering a Malenki can be a little complex; we consider it a medium level of difficulty.

Can I add a spinning weapon to my Overthrow?

The Overthrow ships as a non-destructive flipper bot, but advanced builders can wire in their own spinning weapon system using the unsoldered build option. This will require modifications to the chassis and design work. If you do choose to weaponize with a spinner, please be careful to follow standard spinning weapon safety practices — secure testing in an arena or test box, weapon locks, and the usual precautions. Even a small bot with a spinning weapon can be dangerous. Also, the Overthrow design wins “as is” — weaponizing isn’t necessary for victory.

What battery does the Overthrow use, and how do I charge it?

The Overthrow comes with a rechargeable 7.4V 350mAh 2S LiPo battery, and a 2S LiPo charger is included with this bundle. Never leave a charging battery unattended, and store your LiPo partially charged in a LiPo safe bag when not in use.

What spare parts should I keep on hand?

Hubs, tires, and N10 1650 motors are the parts most likely to need replacing after hard hits or wear. Check the Maintenance tab above for the current parts list and pricing.

What else do I need to run the bot?

This bundle includes a 2S Lipoly Charger for the included battery. You’ll still need a transmitter that uses the AFHDS 2A protocol. Turnabot recommends the Flysky FS-i6, available at ItGresa. The Flysky FS-CT6B will not work with a Malenki — it uses the older AFHDS protocol, while the Malenki requires AFHDS 2A. The “2A” matters. If you need both a transmitter and a charger, see our Transmitter & Charger bundle.

How do I set up my radio?

The Overthrow’s printed assembly instructions include detailed, step-by-step radio setup for the FlySky FS-i6 — covering binding, battery alarm settings, flipper end points, drive direction checks, and how to reverse a channel if anything runs backward. Follow those steps in order for the smoothest setup.

Does the signal to the Malenki need to be mixed?

No — the Malenki-Nano comes with steering mixing built in and enabled by default, so a standard radio works right out of the box.

Tip: If your transmitter is already mixed, you must use an unmixed signal. We know from experience that a mixed transmitter signal + an ESC that does mixing = an unmixed bot– the two mixes cancel each other out.

Tip: How can you tell? If you put your drive stick (right hand stick) in the upper right hand corner (instead of straight ahead) and the bot goes forward, and put the stick in the lower left hand corner and it goes backward, your bot is unmixed.

My Malenki keeps flickering its blue LED — is it stuck in bind mode?

Maybe not — it’s more likely in Configuration Mode, which looks similar but is a completely different state. The key rule is simple: always turn on your transmitter before you power up your bot. If the Malenki comes on with no transmitter signal present, it can slip into Configuration Mode after just a few seconds — well before the 90 seconds needed to trigger Bind Mode. Configuration Mode is easy to exit: just give the bot a quick burst of drive input and it returns to normal drive mode immediately.

What if I strip a screw hole during assembly?

The Overthrow kit thoughtfully includes a few extra M2.5 × 6mm screws specifically for this — they’re slightly thicker than the standard M2 × 6mm screws and will bite into a stripped hole. Keep these separate from your other screws so you don’t mix them up, and only use them if a hole strips out during the build.
