LRP X12 vector 7.5t stuttering

[cornishboy176]

I have got an LRP 7.5t X12 it was stuttering like h*ll and i have just fitted a new sensor board and tried it again and it is still the same and getting hot very quickly

Any ideas

Thanks

I had this and so have a couple of others i know of..only seems to be the X12 7.5???

I tried sensor wire, new rotor.. everything possible realy but no joy!

I sent mine back to Jono at SMD and he replaced it though at a cost.. mine was over 12months old.. but if yours is under 12months old you may get it changed over no probs..

:thumbsup:

hi mate it could be a bearing seizing up mine did a similar thing last week then stopped dead replaced the bearing s and now as good as new

Bearings in mine were fine, they were checked and oiled (this should be done frequently in X12's as then run quite hot and dry the bearings out...)

LRP sell a very handy bearing removal tool

I had the same problem with a brand new X12 7.5.
I found the winding in the motor had so much slack in it that it had vibrated/worn the laquer of itself and was intermittently shorting - causing loads of heat, interference, glitchy power etc etc.

I tightened up the winding - removing about 50mm of wire and resoldered it all back.

Works fine now

My gt4 21x2 is doin the same too. I have just taken it apart again and it looks as though some of the plastic that holds the bearing has started to melt! I have only had it a month. It does seem to get hot quickly. The armature still seems to be spinning correctly and freely also I have two washers and I am not sure which order they go back in. Any ideas?

There is a sensor unit in the motor that could be causing the problem, this one http://www.amainhobbies.com/product_info.php/cPath/1_221_580/products_id/34255/n/LRP-Vector-X-12-PreciSensor-Unit

Also, if the capacitor is broken it could cause nearly similar symptoms...

Hiya,i have replaced the sensor unit and it still the same,Thanks anyway buddy,i am going to try taking it apart and check the windings

Check your capacitors as well

I had the same problem. I changed the cap and now it is better...
