The holes to bolt a motor onto the mount are misaligned. You will need to drill out about 1mm from one of the holes. I read other people had this issue but I took the chance. 1 star because how do you mess up a motor mount.
The compartments are a tad smaller then expected and some of my HO cars are a tight fit and some will not without modifying the dividing sleeves but I have more than enough to fit both cases. Very pleased with quality and the delivery time. Would not hesitate to buy again.
Stay away from this kit. The "instructions" are nearly unreadable, some of the screws are sized for some kind of specialty allen key between 1.5 and 1.27 mm, every single threaded hole is boogered up so bad you can't thread anything into it, and the rear arms are far too short for the TRX4M.
Perfect for my felony 6s , very fast shipping , recieved in perfect shape well packaged !
Would definitely buy here again !
