Default Ally Battery posts & gears

Does any one sell ally versions of the battery strap mounting posts? My plastic ones keep coming loose.

Also any news of metal front gear sets?

Hernandez. I was told by the UK importer of Tribo comm drops that you should never use any comm drops when breaking in a motor, the lower friction created by the comm drops does not allow the brushes to bed in.
Also make sure that you break in the V2 motor for at least 400 seconds at between 2 and 3 volts. Espically when using the enduro brushes as the are very hard wearing.

Edit: I always break my motors in at 0degrees timing. Not sure if this is right, but I have never had any problems.

metal front gear set... not actually a set... more like input shaft with the bevel gear. HPI doesn't have a metal main gear yet...

both front and rear input shafts w/the small bevel gears are now available in Japan... can be ordered through Rainbowten... hope to have mine sometime next week. for the rear I like the one piece input shaft and spur gear mount instead.

I have a question about the spaces for the wheels. I run CS 27 tires and have had a problem stripping out the wheel hubs because of the spacers. I have tried others that are the same diamiter as the HPI ones but they seem to bind. Do i really even need them seeing as they drive me up the wall.

I've had this same problem. I just tighten the wheel nut more... I don't see any damage with a little more tightening in my car.

I use a set of Associated hex's. Just have to drill the inside a little bigger, VERY CAREFULLY. It's a little tough to keep the hole centered but not to bad. They've worked great for about 3 months now.

take care

This shouldn't happen. Are you using more than is required in the manual. If, so, this the source of your problem. You can only use the total amount of what the manual indicates, for each axle / hex drive. A remedy for this, is to buy the Hpi 6mm hex drives. Here's the part no: #33407 Aluminum hex hub clamp type (6mm / 4pcs.) Until you get them, use the middle hole on the suspension arms.

Make sure that when you are tightening the wheel nut that the hex on the wheel is actually fitted into the hex on the car. I had this problem with some wheels with shallow hexes, you've just got to be a bit careful.
