Default T Rex motor instalation

Cant seem to get the screws to line up with the motor in the mounting process. Using the 420 motor that came with the kit. Not even sure which screws to use. The manual shows the allen head screws but they are an odd size and dont have an allen wrench to fit. They are also loose in the motor. The Phillips head of the same length fit perfect in the motor but are extremely tight in the frame. Too tight to move around to get the right gear mesh even if I could get them mounted in the motor. Anyone have any thoughts?..........................Thanks..

The motor mounts with 2 2.6 X 6mm allen head cap screws. A 1.5mm allen head wrench will fit the screw head.

The allen head screws are what the instructions say to use. My concern is they sure seem loose in the smallest motor threads. The slightly larger (3m?) phillips head screws that came in the same packet as the allen heads are a much better fit in the motors larger two holes.. But, they are the ones that dont seem to fit the frame motor mount holes. My obvious concern with tightening the allen screws is will they strip? Am I being overly concerned about the slight "wobble" Im feeling with the screws threaded into the smaller holes in the motor?...........Thanks

With the 2.6mm screw there is absolutely no Play at all. Measure the screws to be sure you're using the correct ones.

Stopped into the local hobby shop and talked to Ron the owner. We put a micrometer on the kit supplied 2.6 mm screws. They actually measured 2.52 mm. He had some Dubro 2.6 screws that actually measured 2.61 mm. Even those seem to loose but he said, and it seems others are using them without any problems. But they sure dont fit like the 3 mm ones in the larger holes............Thanks again for your help...These forums are great........................................

Was going to mount the motor last night on me new Trex but had the same problem the Phillips head screw was too big to go through the frame mount holes and the Allan Key screws seem a bit loose and I need a Allan key to fit them (Dont know why they did'nt put one in the kit).

I think that the Phillips head screws would be the best to use (tight fit means no play) but man is it hard to get the little sods in there place.

Check the kit carefully--- The 1.5mm Allen head wrench is in the kit as are the 2.5 X 6mm ALLEN head cap screws.

To All:

Sorry, I was wrong--The screws are the 2.5 X 6mm Allen Head cap screws, but the cap end takes the 2mm Allen head wrench, which is in the kit.
