Damo88 Posted August 9, 2016 Share Posted August 9, 2016 Hello all I'm Damo im very very new like 2nd day into the hobby. i recently brought a kyosho pureten gp alpha 2 off some one on eBay. It was advertised as full working order but it seems this isn't true. So the issue steering right is fine turns correct amount and returns to front facing but turning left is very slack hardly movement and does not return to front facing at all. I've looked to see if something was obstructing anything but it seems all ok I've braved into the "I have no idea" and took off the entire power box that contains the servos by removing the horns from the actual servo i really don't know what's what and how to fix the issue any help would be appreciated eBay seller has left me hanging no refund offer so I'm stuck with this and not knowing enough to fix it myself thanks in advance Quote Link to comment Share on other sites More sharing options...
Deafty Posted August 9, 2016 Share Posted August 9, 2016 Hello. I know not of this pureten gp alpha 2 . But others will At a guess it could be a simple matter of the servo saver not functioning correctly Maybe the linkages are binding on the offending side. Is the steering free and smooth with the servo horn off? Perhaps the servo is naffed. Does it function correctly with the horn off? Got any pics? or a small vid would be useful Welcome to the madness btw Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 9, 2016 Author Share Posted August 9, 2016 Drafty thank you for replying , my knowledge of everything rc is very very small so i didn't understand everything you mentioned I'm sorry I'm a noob ? with the horns disconnected they work just fine move same distance and return to center position so I'm thinking these are working right so I think it's the actual bit the steering rod is attached too ill try try post a picture from my phone now thanks for your input so far !

Damo88 Posted August 9, 2016 Author Share Posted August 9, 2016 I think the issue is here as like I said the servo moves fine when disconnect from the horn/rod ect ect Quote Link to comment Share on other sites More sharing options...
dazp1976 Posted August 9, 2016 Share Posted August 9, 2016 That be the servo saver, is it spring loaded, is it loose. Don't know about these but when my steering was a bit stiff it was my top plate acting like a clamp when put back on the steering posts. I had to put some washers in place to act as spacers and free it. Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 9, 2016 Author Share Posted August 9, 2016 It feels fairly easy to move the wheels right but left is tight and even tighter trying to put it back in the center after moving it left so yeah stiff left loose right , thanks for the advice I'll have a fiddle and see if I can do anything as a fix here and thank you for educating me ?

dazp1976 Posted August 9, 2016 Share Posted August 9, 2016 Check the steering arms as well and the rods themselves. There could be a tight bolt binding it. Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 9, 2016 Author Share Posted August 9, 2016 Right lil update I re attached the horn to the servo several times trial and error and now the right is fixed but the left won't return to centre ... Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 10, 2016 Author Share Posted August 10, 2016 Okay so by moving the horn on the actual connector but of the servo tooth by tooth I managed to get the flat spot in the middle So turn left then release and it retracts same with the right so basically the the problem is equally spread between left and right so either way when I let off steering it retracts back just not far enough for it to be facing straight. i guess you could say it's a flat spot I don't know how to word this I'm sorry lol Quote Link to comment Share on other sites More sharing options...

You would need to tighten this back up It would also give you loose steering in the centre Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 10, 2016 Author Share Posted August 10, 2016 I think that you may well have it right there mate ! I put the car back together last night .. First time I ever took one apart at all so was slow process lol but I'm going to pick some fuel and new glow starter up today as eBay seller supplied me with a duff one and give the car a run to see how it reacts to the steering if it won't ride straight I'm going to take the servo saver and have a closer look thanks fir for the help so far guys !!

Its good to take it apart and put it back together, gives you a much greater idea of how things work, also how they might break.

To set this straight you want to take off the servo horn, turn on your electronics. Have the trim on 0 or neutral then make sure the wheels are straight and put the servo horn back on. You may have to adjust the trim slightly but you shouldn't have to adjust it much Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Seems the servo saver has gone back to being tight again and not returning to neutral so I'm going to see if I permanently free that up then I'll do what you said with servo horn and that and I'll update thanks to all who've helped so far Quote Link to comment Share on other sites More sharing options...
Sayce97 Posted August 11, 2016 Share Posted August 11, 2016 Make sure to checkout the link Ian W posted. The servo saver works differently to what i thought but my guess the plastic recommends to prize open is causing your problem Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 11, 2016 Author Share Posted August 11, 2016 So new servo is in took the entire front apart and nothing looks bent or broken the servo saver seems to be fine .. Car still not steering right tho it's not pulling to one specific side like it was its now .. If I steer left and release it pulls left if I steer right and release it pulls right ... ?? I double checked for damage and servo saver and nothing appears to be at fault outta ideas ... Quote Link to comment Share on other sites More sharing options...
Ian w Posted August 11, 2016 Share Posted August 11, 2016 What radio system are you using? try swapping channels ie: plug the throttle servo into the steering channel and see if it still does it is your receiver battery fully charged or if you are using AA try changing them Any chance of getting a video up so we can see what is happening 1 Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 11, 2016 Author Share Posted August 11, 2016 I'll try all of the following ! I'll try get video later with phone , as for radio system I'm using perfex kyosho controller with perfex servos Quote Link to comment Share on other sites More sharing options...
Ian w Posted August 11, 2016 Share Posted August 11, 2016 Yeah there are not brilliant but usualy O/K it would have come with the car. Thought you said you had got a new servo ? Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 11, 2016 Author Share Posted August 11, 2016 The eBay seller sent me a second one today so I'm guessing he has few of these cars as it was the same brand Quote Link to comment Share on other sites More sharing options...
Damo88 Posted August 11, 2016 Author Share Posted August 11, 2016 Problem solved ! New servo saver and handles fine .. Got the car started went for a little run and wahey new issue throttle but car moves dead slow even full throttle still slow moving it will pick up speed eventually but I cut it off and went back in the house as something is for sure wrong Quote Link to comment Share on other sites More sharing options...
