You might want to look at the Himax 2015 or 2025 with metal gearbox here.[link=http://www.maxxprod.com/mpi/mpi-262.html]HIMAX[/link] It a MUCH better solution than GWS plastic gearbox. I have both. The brushless motors are a bit much for the GWS gearbox. You also get 3 different gear sets with the Himax gearbox. Gives you more flexibility in setting up your planes.
