| Two speed tranny.
Has anyone had shifting issues with there two speed transmission, I've burn up two HS65 servos in two days. If y'all have any suggestions I would really appreciate your input. |

Adjust the EPA of your servo. Should solve your issues...

I've tried that, I just bought the Futaba 4PL so I'd have that capability.

I was burning up 67 oz HiTec servos on a dig unit, until I put a full size on it.

I had to go back to a full sized servo as well. Burned up two minis. Too bad the full size fits like crap. You can make it work but it still bends up the floorboard slightly. Also had to remove the tabs underneath the shifters and CA them on.

Can you still use the mini servo if you go to a shorter servo arm and use more of the throw of the servo? Just thinking about the forces on the servo and how much it has to exert to stay in or out of dig.. |

Ya I did try the full size and it worked fine with no issues but my interior was dang near bent in half so I took it out and tried the minis. Is there a bad--- regular tran's I can put in there instead??

Oooo I see, well Im running the pro4 4000kv on 4s and it is super nasty but I really liked the extra I seem to get from the two speed but I'm pretty sure I'm done goofing with those dang servos. Harley has his Bomb proof tranny tread on here so I think I'm just going to go that route.

I got that transmission so I could have the choice. High or Low.
