I tried the auto tune...no joy. As for my control system, it's a nce powercab

Esu v5 . ...One with legoman sound 2 with Jamie goodman, all run jerky. My 6 bachmans with Esu v5s and various sound files including factory fitted are super smooth

Can anyone give me some pointers on how to get the Hatton 66s to run at a crawl and stop being jerky. They all have vs sound, but at speed steps 1 to 10 are jerky. My Bachmann ones are perfectly fine out of the box. My layout is a depot layout, so slow speed is required. I have tinkered with some of the motor control cvs on one, but to no avail. The locos are well run in on a rolling road. Ta in advance

Certainly have, my hattons ones are now shelf exhibits lol. I fitted the esu file which is very good along with a boom box speaker from rails exclusive, my others have Jamie goodman with megabass. Both combinations have the correct sounds for the 66, the nice high pitch tone, which the em2 just doesn't give, I think someone demonstrated the esu file recently somewhere on here. But I can get my 66s to crawl at a snails pace without any jerky movements.

I got the db cargo 66117 no noise issue, but it was a nightmare over insulfrog points at slow speed, it's fitted with sound, the esu file and would stall and the sound would cut off as soon as it hit the frog. I fitted a stay alive and now it's fine, very good slow running from step 1 to 10, will crawl along. I've ordered another cargo with factory sound, but will change the speaker to a megabass . Plus I will renumber it.

It's a shame hattons didn't do the latest db cargo red livery, now Bachmann have released theirs. I don't know if Hatton will ever be releasing any more in the future, but the db was a missed loco. Would also be nice to see the newer lighting as seen on many 66s with all 4 lights, the Hatton lights don't seem bright white enough on certain models.

I've installed a stay alive from dcc concepts and this has cured the issue.

Yep, found there was an issue with mainly the centre wheel pick ups. What is the best method of splaying them, seeing they seem to be naturally sprung. I've fitted a stay alive in the new one and that's improved it no end, will get some more in new year.

My db one runs like a bag of nails over insulfrog points, it stalls, shorts, lights flicker when passing over the frog. I've today replaced 2 points with electrofrogs and they are much improved, can get it to crawl on speed step 1 over them. I've also ordered a stay alive to see if that helps with my remaining insulfrogs, don't fancy ripping them all out. My older 66s are generally fine. I have 3 Hattons 66s and they are very jerky at anything upto speed step 10, whereby the Bachmann 66s are silky smooth. I use an nce power cab. Might be worth checking the pick ups as I noticed on my new one the centre wheel pick ups weren't touching the wheels. Also noticed whilst on the rolling road if I lifted one end of the loco off the rollers, it stopped running. It also wouldn't run unless it had all the rollers under each axle, take one out, loco stops, bit strange for all wheel pick up.

Hi. I have a brand new Bachmann 66 in the db cargo livery. I've fitted it with a v5 loksound decoder. It's been fully ran in in both directions on a rolling road. When on the layout, bearing in mind mine is a depot layout and requires slow speed operation, it tends to often stall or a short occurs on points. My trackwork is all peco code 100. As the leading wheels hit the frog, it will often cut the sound and stop, sometimes the leading wheels will pass over the frog and it the rear wheels that cause it to stop. Sometimes, when it has cut out, if I touch the bogie or body, it will start to move again, though I have to reset the sound. It doesn't do it on specific points all the time, can be random. If I move the loco at a higher speed, I can see the lights flicker as it passes over the point frogs. It will go over the point blades fine, it's more to do with the frog and it also seems to happen more in one direction than the other. My previous purchase of 2 Bachmann 66s seem more tolerant. The layout is fairly new build, with all new track. I also have a few Dapol 68s and Hatton 66s all of which have no issues over the points. I've checked to see that the pickups are all touching the wheel backs. ...If even tried the old nail varnish trick on the frogs, but it still stalls.....anyny help would be appreciated

They do a replacement for the Bachmann 66 too, which allows the lighting options including the 4 white lower lights to be illuminated. Maybe the can do that for the Hatton 66 as many are receiving the new light clusters.

Yes, I removed mine, the bass was totally not what a 66 is like. The sound needs to escape, with the Hatton model as it stands it's trapped in the loco. I've got a Jamie goodman file in both a hattons 66 and Bachmann, and the Bachmann is far more realistic, nice high pitched whine that the 66 has. Both are fitted with megabass speakers. I've tried the speaker in both orientations in the hattons. My plan is to drill a number of small 1.5mm holes under the roof grill as per Bachmann and see what happens.

Sound file is good, in my humble opinion the em2 is the wrong speaker, way to bassy. I've a mix of megabass and a boombox on mine and they have a much more quality sound. I also note the Hatton loco doesn't have slots to allow the sound to escape upwards, in essence, there's a solid baffle in the way. On the Bachmann 66,sound can freely emit with minimal obstruction due to the slots in the top radiator . I'm tempted to cut some slots into the radiator on the Hatton model to see what difference it makes.

Got one today, got the body off easily...but gently.then added stronger adhesive over the detailing parts on the body shell. Chipped tested, body wobbles as predicted, so removed and cut back the axle box shafts, glued back in place and now steady as a rock.

Sounds pretty good, had a look on the esu website at ìt, apart from the bits in Germany, it's better than some of the UK based sound providers. Unfortunately I don't possess the esu programmer to do it.
