madMARTYNmarsh Posted January 9, 2012 Share Posted January 9, 2012 (edited) Yesterday I started my break in on my new savage. I did the 2 tanks with the truck off of its wheels (rested the truck on a paint tin ) I then took the truck + my 2 kids to a car park to do 2 tanks going in circles at half throttle, the first (technically 3rd) tank went fine up until the end when for a second the truck stopped moving and when I throttled the engine reved but the truck didnt move. Suddenly it moved again so I though that maybe there wasnt enough fuel and thats why it behaved so strangely. I filled the tank and had a quick look over the working parts with the lid off but everything seemed hunky doorey sdo I re-started the truck and off it went for about a quarter tank until this happened (excuse the poor videoing as I was doing it while trying to make the car move) the problem starts at about 0.17seconds..... LINK This happened twice more, both times a looked under the lid to see if anything had slipped or moved but everything loomked perfectly fine. When I got home I removed the lid and found loads of black plastic thrown all over the place, the best thing I can do is show you..... LINK I cant see where this plastic has come from, the spur gear looks like its still brand new. The only thing I can think is that it has come from the clutch? This is an rtr truck all I have done to it is put in the reverse module, I havent touched the engine or anthing in that area. All help and advice is greatly appreciated!

norcoforever Posted January 9, 2012 Share Posted January 9, 2012 has your engine moved on its mounts? just to confirm have you checked your mesh? Quote Link to comment Share on other sites More sharing options...
chrisknights Posted January 9, 2012 Share Posted January 9, 2012 have you looked at the nut on the spur gear to see it that is tight , some fully tight it up and undo 1/4 turn to allow it to slip but i do it fully up Quote Link to comment Share on other sites More sharing options...
madMARTYNmarsh Posted January 9, 2012 Author Share Posted January 9, 2012 Yes sir I have, My mesh Is fine. I just edited my post because a whole section dissapeared. If you take a look at the second link you will see what I mean.So I tighten it all the way and undo it a quater turn? Will it still work as intended?

grumpygramps Posted January 9, 2012 Share Posted January 9, 2012 (edited) Looks like clutch shoes to me... I think I'm right in saying that they put plastic ones on the RTR's, which are best replaced by something like the red Hong Nors. EDIT- Here's the shoes http://www.ebay.co.uk/itm/Hong-Nor-Super-Long-Life-Alum-Clutch-Shoes-Red-/400260969878?pt=UK_ToysGames_RadioControlled_JN&hash=item5d3169b596#ht_1597wt_1344 Edited January 9, 2012 by grumpygramps Quote Link to comment Share on other sites More sharing options...

madMARTYNmarsh Posted January 9, 2012 Author Share Posted January 9, 2012 Is there any reason that this would happen at the end of the first tank this truck has spent on its wheels? surely they should last longer than that? Quote Link to comment Share on other sites More sharing options...
wiggy2k7 Posted January 9, 2012 Share Posted January 9, 2012 (edited) i dont think the clutch shoes are made of plastic. i see you have the reverse module, could it have got stuck in netural maybe Make sure the slipper clutch nut hasn't come loose and is slipping Edited January 9, 2012 by wiggy2k7 Quote Link to comment Share on other sites More sharing options...
mini-z-awd Posted January 9, 2012 Share Posted January 9, 2012 for the stopping it could be something todo with the reverse you have on your savage sometimes they will just jump out of forward gear. like when your going from forward to reverse it wont engage properly and vice versa and the standard clutch shoe do suck they are only put on because there cheap to buy for hpi so would need replacing sooner rather than later Quote Link to comment Share on other sites More sharing options...
madMARTYNmarsh Posted January 9, 2012 Author Share Posted January 9, 2012 Im not going to say no because my knowledge is severly lacking but I have it fitted very tight (the little silver bit that pulls out to engage reverse has very little play until I actually engage reverse) so I had hoped it wouldnt happen. I think I may remove the reverse for now. Quote Link to comment Share on other sites More sharing options...

madMARTYNmarsh Posted January 9, 2012 Author Share Posted January 9, 2012 And they are BLACK just like the plastice that has been sprayed every where.... would you say that clutch shoes are made of a fibreous kind of plastic as the plastic particules seem quite bitty?

Stonedscotte Posted January 9, 2012 Share Posted January 9, 2012 Hi mate it does look like your spur gear has stripped and the cause could have been the reverse module. As you said take it out and put a metal spur gear in. The only problem is if the mesh isn't correct you can strip gears. Quote Link to comment Share on other sites More sharing options...

Richard.S Posted January 9, 2012 Share Posted January 9, 2012 i think its the reverse module too.. I've had no end of trouble with mine. Quote Link to comment Share on other sites More sharing options...
grck1 Posted January 9, 2012 Share Posted January 9, 2012 You have exact problem I have by the look of things, mine loses drive momentarily then you see the truck give a little jerk and drive is restored. I also have the debris around the clutch bell like you do. This I thought down to spur but no it fine, then thought reverse setup but after playing around established it wasn't as it did it without it fitted. It is the clutch shoes disintegrating, mine also were new only three tanks ago and cheap and cheerful, going to get some quality ones when I get some money, Quote Link to comment Share on other sites More sharing options...
madMARTYNmarsh Posted January 9, 2012 Author Share Posted January 9, 2012 (edited) Sorry to hear your having the same problem grck1 but I'm also glad because It's not just me (sorry to be selfish LOL). Looks like new clutch shoes are in order, as well as the removal of the reverse gear. I got to be honest, I feel a bit dis-heartened. Im not rich but I don't mind spending money on a hobby, it normally adds to the enjoyment I get from it but it already seems like this truck is a money pit, if bits go wrong then fair enough I replace them without question but they normally have a fair amount of use, this clutch shoe has gone after one real use (I'm not counting the first 2 tanks as the wheels were off the ground) I know I'm new to nitro but i wouldn't call 1 half throttle run a fair amount of use. Good job I don't quit easily. Sorry to whine at you all. Thank you to all of you who offered advice and help. Hopefully this is a once in a blue moon type thing!

Royal Male Posted January 10, 2012 Share Posted January 10, 2012 My advice would be to take out the reverse module, call hpi: http://www.hpiracing.co.uk/faq.php and plead ignorant......2 year warranty on their models...apparently. be persistant.

wiggy2k7 Posted January 10, 2012 Share Posted January 10, 2012 its not normal for the clutch to be shot within a couple of tanks, something cant be right Quote Link to comment Share on other sites More sharing options...
