Grant Posted January 3, 2018 Share Posted January 3, 2018 Hi I have just bought a Hyper 7 sport TQ and the brakes on it are shocking it just does not stop. I have adjusted them which made this a little better but they are not good. Can anyone advise? I think the servo for them is under powered but do not know what servo to purchase any recommendations for a high torque servo and brake and throttle linkages would be gratefully revived. Also upgrade brake them self for the car . thanks Grant Quote Link to comment Share on other sites More sharing options...
Wraithstorm67 Posted January 3, 2018 Share Posted January 3, 2018 Does it have savox servos I have one which came with them as standard Quote Link to comment Share on other sites More sharing options...
Grant Posted January 3, 2018 Author Share Posted January 3, 2018 Hi no do not think so the label on them is HoBao H-101 Quote Link to comment Share on other sites More sharing options...
locky Posted January 3, 2018 Share Posted January 3, 2018 H-101 servo are about 3kg torque so a little under powered. If you have adjusted linkage and transmitter settings with no improvement then a servo with more torque will sort it. Power HD LF-20mg will be plenty (20kg torque), I use them for steering 1/8 cars and also for some throttle/brake servos. If you dont mind waiting 2-4 weeks then can get them for about £13 from ebay china, or quick delivery from rcmart in Hong Kong, usually 1-2 weeks...http://www.rcmart.com/digital-servo-used-crawler-buggy-onroad-p-59604.html?cPath=1099_1030.

Grant Posted January 3, 2018 Author Share Posted January 3, 2018 great thanks will give them a shot. Do you recommenced any upgrade on the linkages as well? Quote Link to comment Share on other sites More sharing options...
locky Posted January 3, 2018 Share Posted January 3, 2018 Stock linkage is OK. Recommend using 6V nimh pack and not 4 x AA alkaline batteries, as voltage will quickly drop with alkalines whereas nimh have a flatter discharge rate, or 6.6V LiFe pack even better. Push car along and apply brakes until they bite and you cant push it, but you still want them to feel progressive. 1 Quote Link to comment Share on other sites More sharing options...
Grant Posted January 3, 2018 Author Share Posted January 3, 2018 Ok will get on of these as well. What is noticeable is even when I apply pressure to the servo I can still push it forward a bit Quote Link to comment Share on other sites More sharing options...

I had a look at the 6V nimh pack on ebay but these will not fit in the battery housing as there is 5 batteries in them Quote Link to comment Share on other sites More sharing options...
locky Posted January 3, 2018 Share Posted January 3, 2018 What type of battery box do you have? Either a hump pack or stick pack. If you have the box with receiver inside and battery then the hump pack fits, it the battery is separate then I cant remember which is best stick or hump, suggest you search...

Smoothybb Posted January 3, 2018 Share Posted January 3, 2018 You could convert it to quad brakes but tbh, if it's that bad on dual, adding another set won't help until the real problem is sorted. Quote Link to comment Share on other sites More sharing options...
Grant Posted January 11, 2018 Author Share Posted January 11, 2018 Well new servo came and batteries all fitted but breaks are still weak. The new servo looks like it would break the servo arm so it has plenty of strength in it. Any ideas? Quote Link to comment Share on other sites More sharing options...
locky Posted January 11, 2018 Share Posted January 11, 2018 (edited) My stock brakes are good on stock Hyper 7 TQ with Savox servos, which would indicate something wrong with linkage/discs/pads. Tighten two hex screws which secure the discs. With electrics off rotate servo arm to full brake until cant move, if the brakes arent workng, ie. wheels dont lock when pushing car on ground. then your linkage needs adjusting. Is this a brand new Hyper? Also check your tx end points, there are some dials which will alter these for both servos.

legoluke.11 Posted January 13, 2018 Share Posted January 13, 2018 I think you can still push it along when the brakes are applied the servo isn’t that powerful. Check to make sure the little plastic pieces that hold the linkages onto the servo horn aren’t tight as this will prevent free movement of the servoSent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Go for the tq 2 brakes 10 quid on ebay straight fit .idealy you need savox 1256 steering servo .savox 1257/58 throttle servo .both metal servo horns .the tq2 servo tray thats if ur reciever is small and the tq2 brake set up .
