Harcoreta, a member in the RC Groups forum, has created quite a stir with his 3D printed jet engine. This 3D printing endeavor was time consuming, boasting 60 blades in all. Harcoreta plans to tests out the scaled model of a Boeing 787’s GE-built turbofan jet engine on an RC plane in the very near future.
