Looks like I'll be another proud owner of a clutch basket next week. Ran my truck Saturday and installed a HD slipper pad. Getting some decent slip out of it and by the end of a pack you could really feel it's acceleration getting slower from the slipping pad. Didn't melt anything but definately heated it up.

Other than that I worked on my driving skills and was getting more use to the truck. Still didn't complete a single fully clean lap but by the end of practice I wasn't flipping it over every time and had most sections down pretty good. Can't wait to race this truck again.

The only issue I had other than the slipper was a shock shaft pulling out of the rod end on the right rear. Landed from one jump on the top of another and wrenched the shaft out of the rod end. Dropped in a little CA glue then re-threaded the shaft into the rod end and no more problem. Will be tearing down the truck this week though to see if anything else is damaged...figure better safe than sorry. I beat the snot out of this truck and so far it has taken whatever I can throw at it...which is saying a lot!

lrp's seem to run hot naturally. i would say go to 12 but i bet it wont help. what speedo? any timing? as someone else mentioned my wheel hexes where rubbing the bearings. causing drag. also make sure you temp your slipper when your done! if its ridiculously hot then your slipping so much your motor is not happy.

Got it! going to homedepot now...thanx!

What temp is too hot? What would be a normal temp? I'm going to check this out next week...my slipper seems to be working fine and I race on a high bite clay indoor track but since I've never temped a slipper I don't know what numbers are what

Where are you topping out at down the longest straight? After talking with the Late Big Jim, one of the premier motor guys of his time, he advised me to always start my gearing to top out towards the end of the longest straight, then adjust it from there. Based on his suggestions, I have never overheated a motor since. Give it a try (assuming all else is fine with the vehicle)

The manufacturer probably had a card or something stating a safe temp, but in general about 150 - 170 could be considered safe. Also keep in mind that when you actually temp, your motor was probably hotter at some point too, so kind of factor that in.

with my slipper issues it was up to 160 what seems to be normal is 100-130 while 130 is starting to get hot.

160 is where most motors max, X12s max at 210. Staying at least 10 under the max recommended temp is easily safe and achievable. Remember, brushless motors have a sweet spot between timing and gearing. They'll also run hot OVER or UNDER geared! No need to worry about the motor falling off that hot with 2S. 1S most motors will start falling off around 140.

The belt is in the middle maunting holes inj the front and rear. I will double check for binding in my hexes/ hubs but I dont believe they are. The motor plate screws are good as well, I checked them the other day. Thanks for your help, I'm gonna try some of this and let you know.

Honestly, I have never heard of undergearing with brushledd motors. I'll go to 14 and see how that runs. Thanks.

not too surprised, that seems to be one of the common things that people don't know about. Whats really bad is that people then smoke these motors that cost a lot more than what the older brushed stuff does.

It tops out right around the first 1/3rd to the middle of the straight and I have a ton of accelleration out of the corners. I'm gonaa try going 14/62 and see how that goes.

What would you say is a good temp for the slipper to be after a five minute heat and a 10 minute main? Thanks for your input.

[QUOTE=lodhammerdin;9437014]Definitely gear up.

Check it out
My LRP 550 5.5T runa between 140-180 geared 14/62 w/10deg of advanced timing, temps seem to vary from weekend to weekend, if in don't servise the trucks diff's and difff cases they seems to bind a little causing heat.

Hey Lod, when your motor was 230ish, was the speedo hot?

It was temped at 140ish. Its an SPX8 with a Fan on it.

[QUOTE=Cain;9437111]Thanks, Gonna go to 14/62.
