Zenoah G290RC 29cc 4 Bolt 2 Stroke Engine /w Walbro WT-990 Carburetor.

One of the most popular upgrade engines for the HPI Baja series and the Losi 1/5 scale trucks/buggies. Zenoah engines are the best in the business and only use the best materials for their engines and components, all their engines come with a Walbro carburetor and an NGK spark plug to complement their engines and ensure they run at optimum performance.


Do keep in mind that for most (including all the models listed below) RC models you will need to install the standard air-filter and exhaust (that came with your RC car).

The Losi 5IVE-T & The Losi DBXL:

You will need to use your clutch mount and flywheel cover from your old (stock) engine for correct installation. Everything else should fit nicely.

The TLR (Losi) 5IVE-B:

Unfortunately you cannot use the stock clutch mount or the flywheel cover like you can with the Losi 5IVE-T & the Losi DBXL (because it doesn't come with one). We recommend you purchase a shorter clutch mount and a Rovan flywheel cover or a HPI flywheel cover separately for a better installation.

The HPI Baja 5B / HPI Baja 5T / HPI Baja 5SC:

It's recommend that, purchasing a shorter spacer (some alternatives are the: HPI-102164, HPI-87458 & HPI-87571) is better for a correct installation (as the Zenoah clutch mount's mounting stud is too long). Everything else should fit nicely.
