Update slop reduction successful

[NeoSlayer888]

Picture numbers go from left to right.

Picture 1: Red is where gear can engage.

Picture 2: Pieces that would be cut out of aluminum, plastic, or a similar material

Picture 3: Yellow is what Picture 2 would be glued/attached to.

Picture 4: Blue hatching is Picture 2 installed.

Picture 5: Same as Picture 4 but the red once again represents where the gear can engage.

This is my new plan for reducing the slop in an E-Maxx tranny. It is actually my sixth idea on reducing the gear engagement area. Once again any replies are welcome, just as long as they are constructive.

good idea, far cheaper than re-machining the gears. but as said by someone in another post...you'll have to be going alot slower, if not standing still, to shift gears.

I think that would be fine for crawling

My thoughts exactly, during testing when the motor was at full speed and the gear engaged it made a loud noise. But when I just blipped the throttle until it engaged it made no sound at all. My other idea if this works is to redesign every gear in the tranny so I have a greater difference between 1st and 2nd gear. One could be supper low and the other moderately high. That way you get a crawler ratio and a momentum ratio. If the gears are the same size but different pitch and tooth count it should work.

i'd be really interested to see how you make a wider gear ratio between first and second. sounds like a good idea. that way you got low end torque and higher ratio for more speed!

I have not had the time to work on my X-TXT so I have not tried my gear slop theory. I have been thinking about how to widening the ratio and I don’t think it is going to happen. There is no room in the case to fit bigger gear and I don’t have the time to fool around with different gear pitches. Maybe when I finish summer school, read the two books I need to read for AP Language, do a 100+ entry dialectical journal, and write an essay .

My modified gear worked on my test bed. My test bed is E-Maxx tranny in vice and my shifting servo (HS-81MG “click for info") in another vice. The motor used is a Trinity P2K. I have no idea if it will work in an actual vehicle. When I get more money I will find out.
