Out Of Batteries For Your Torch? Just Use A Mini Nitro Engine

We can certainly relate to an incomplete project sowing the seed for a better one, and that’s just what happened in [JohnnyQ90]’s latest video. He initially set out to create an air compressor powered by a nitro engine, and partially succeeded – air was compressed, but not nearly enough to be useful.

Instead, he changed tack and decided to use the 1 cc engine to make a small electric generator. [JohnnyQ90] is, of course, no stranger to the nitro engine, having previously brought us the micro chainsaw conversion, and nitro powered rotary tool. This time round, the build is a …read more

Micro Chainsaw Gets a Much Needed Nitro Power Boost

When life hands you the world’s smallest chainsaw, what’s there to do except make it even more ridiculous? That’s what [JohnnyQ90] did when he heavily modified a mini-electric chainsaw with a powerful RC car engine.

The saw in question, a Bosch EasyCut with “Nanoblade technology,” can only be defined as a chainsaw in the loosest of senses. It’s a cordless tool intended for light pruning and the like, and desperately in need of the [Tim the Toolman Taylor] treatment. The transmogrification began with a teardown of the drivetrain and addition of a custom centrifugal clutch for the 1.44-cc nitro RC …read more

3D-Printed Parts Torture-Tested in Nitro Engine — Briefly

Additive manufacturing has come a long way in a short time, and the parts you can turn out with some high-end 3D-printers rival machined metal in terms of durability. But consumer-grade technology generally lags the good stuff, so there’s no way you can 3D-print internal combustion engine parts on a run of the mill printer yet, right?

As it turns out, you can at least 3D-print connecting rods, if both the engine and your expectations are scaled appropriately. [JohnnyQ90] loves his miniature nitro engines, which we’ve seen him use to power both a rotary tool and a hand drill before. …read more

Nitro Powered Rotary Tool

We really don’t know if the world needs it but we’re sure glad [johnnyq90] took the time to build one. We’re talking about a nitro powered rotary tool. Based on a Kyosho GX-12 nitro engine, commonly used in R/C cars, [johnnyq90] machines almost all other parts in his shop to make a really cool ‘Nitro-Dremel’. But success didn’t come at the first try.

The first prototype was made using a COX 049 engine but the lack of proper lubrication cause damage to the crankshaft. Because of this setback, [johnnyq90] swaps it out with a O.S Max 10 Aero engine he …read more
