Ok I got the frame stiffener and the battery tray set up from Xtreme and was installing it and the directions state that you use the long screws in the kit for the two holes on either side of the main bearing and one also on the front, but used two seperate screws on the holes just behind the motor. I took a look at the thread on the stiffener when it first came out and it looks like that one used the long screws on all of the bolt holes and they all went through the plastic frame and threaded into the other side of the stiffener. I guess in short the stiffener I have is different than the one shown earler. Now it seemed that I could only get one of the shorter screws to thread into the plastic frame from one side and the other just went all the way in and didnt thread into anything. The stiffener I have has oval holes on both sides for the mounting point just behind the motor and this is different that the one I saw before. Have they changed the design?? Now I fixed the problem with a piece of m2 threaded rod and two aircraft style nuts so it kinda works like the other bolts, but was wondering why they would change the design as the original I saw was much better.

Where did you get if from??? Mine came with 4 long screws... al of which threaded straight thru into the alum frame on the other side and two screws, short for motors. I used my own.

maybe got a goofy package... email them and ask they will no doubt sent you the right scews.

happy fly'n

I got it from a guy on Ebay that I think is in Canada (Buzztron) and have gotten other Xteme parts from him in the past when I couldnt find them in other places. Mine also came with the fourth long screw, but it wouldnt work seeing that there is an oval hole on both sides so no threads to thread into. Go figure, I probily got the only messed up package. Any way it still works with the threaded rod and the two nuts.

No, no change its just that the orignal frame was designed for those tiny screws that go though it and one side of the frame has larger holes then the other. I found that taking two 2-56 allen head bolts and cutting them down so they only go in half way on each side works better then the supplied 2 screws. Do not leave these out as they support the frame behind the motor where it breaks and that is one of the reasons you bought the mount, the reason they have ovel holes for the minor diff in the frames in this area on each side. Also check to be sure you cut out enough of the mount to fit the frame stiffener properly as it provideds a spacer and flat mount for the motor however if the stiffener is not sitting flat in the frame the motor will twist and this will affect the mesh of the pinion with the main shaft. My stiffener had a burr on the bottom and I didnt notice it till I was tightening the motor and noticed the motor was cocked to the side.
If you need long replacement bolts there are sold as muffler bolts in LHS.
