This is a great chassis to get started in crawler building. I waited a couple months to write review to see how it holds up, and I have to say that I'm impressed.... especially for the price. I put a Hobbywing Fusion 2300kv in it, and on 3s it's too fast for a crawler. This planetary transmission along with the Fusion is almost silent. I love it! Becoming a fan of Injora

Purchased this for a project build to work on the build quality and metal parts are fantastic quality.Drop box is arranged input pass through output to the middle rear shaft. So you will need to swap your rear end diff if you want to use it with 4x4. The left side and right side outputs run at different speed for over drive on the front.Needed a little tweak on the rails for the transmission to line up correctly. The micro servo hand burs on the gears inside the gear box of the servo that rendered it not able to fully switch gears.The forward gear was assembled backwards so the clutch could not engage it correctly.No grease at all in in the gear box or the drop box.

Transmission is junk broke the output shaft in half
