HAYA Centurion Mk3. First Impressions.

[zooma]

It could be that I need to upgrade with a pair of more powerful motors so that I can run the tank on any surface other than those that are smooth and flat........it would also be nice to be able to run it on a well cut dry lawn or ....an undulating surface ....

I would like to hear from other owners of the HAYA Centurion to find out if this is lack of power and performance is "normal", or if my example just happens to have a pair of very weak motors.

I made a number of modification on my Haya Centurion with TK50. Loving the process of modification.

And yes, I did changed to a different motor. I have tried a few different RS380 motors and I arrived on a set of Mabuch RS-380SH-4535 which I think the speed is reasonable (fast) on 2s.
My son has a really different opinion though because with actual centurion, the actual tank that is using the Rolls-Royce Meteor is really underpowered at 650hp and not really fast at 34.6 km/h.

I have also tested with a slower motor and similar motor at a 3s Lipo, that made the tank pretty fast.

I think the regular motor that came with the tank is sufficiently fast.

I typically used a set of Gaoneng 65000mAhr Low profile HV lipo for my tanks

Hi onbenghui,

Good to hear from somebody who was also disappointed with the performance of their HAYA Centurion - but more interestingly - someone who has found a fix that works.

More speed is not as important to me as having enough power to be able to drive my HAYA Centurion across my lawn or having enough power to turn when “on the move” or to clamber over small undulating surfaces.

I honestly don’t think I am asking too much as every one of my other tanks can do any of the above without breaking a sweat.

My HAYA Centurion always feels like it has a flat battery (!) and that has never been the case.

Can you let me have a link to the source of Mabuchi RS380SH -4535 motors please ?

Many thanks,

Bob.

Bit too far for me to travel to show you mine!

Those Mabuchi motors are probably like the stock Tamiya offerings. I have two spare at home.

I will probably be able to find some 380 motors on eBay, but I am keen to find a pair that are better than those that I already have !

It seems like there are a lot of different 380 size motors, and I need to be sure that I can find the right type that will perform better than the ones that came on the tank from new.

Dragging the tracks around by hand feels free enough, so I don’t think anything is snagging or binding that could be robbing any power away from the motors.

I don’t suppose there is any possibility that my Clark board is failing to pass on enough power to the motors is there ?.......probably just grasping at straws now (not had a Clark board in a tank before)..........so I will start looking for some replacement motors.

Anyone that can provide a link here to any 380 size motors that are known to be better than what I already have would be greatly appreciated

These are the motors I have put into both my Challenger and T72. The standard Heng Long motors struggle to pull the skin of a rice pudding, let alone move a tank on grass, that weighs in at 8.5kg.

Much apologies, but I am Not disappointed with the performance of my Haya Centurion. In fact, I think the quality is exceptional compared with others.
For instance, none of the popular brand even have any spring loaded tensioner, and some cannot fit in a typical rc car hardcase pack.
However, I just love improving on the existing good design so far.

I can only quote that my son came in third on a regional rc tank event first time driving it over a course. For for us, driving around a grass patch over tree roots are not uncommon.

I got those from some online shop, but i think the Mabuchi RS380SH-4535 were commonly available on ebay.
It does make the tank faster, and my motor spec is around no load 15Krpm at 6V.

Just FYI, due to the size of the hull, I don't think they can fit a typical 390 motor. I tried, but any end bell of the 390 motor will hit the opposite gearbox.
380 motor will fit comfortably.

Hi ongbenghui

I note your comments about the HAYA quality but also your motor upgrades.

There is no problem with the HAYA “quality” as far as I am concerned either - but like you have already done - I would like to improve the performance a little - not to make it go faster especially - but to enable me to be able to drive it over my lawn and the same mildly undulating terrain that I drive my other tanks over.


I read your comment:- “For for us, driving around a grass patch over tree roots are not uncommon” ....with a little envy , because mine does not have enough power to drag itself over my well cut lawns or even turn particularly well when moving.


Your motor improvements now give your HAYA Centurion the ability to do exactly what I want to be able to do with my HAYA Centurion - drive it and enjoy it


I really do like my HAYA Centurion- but I would like to improve its performance only to the extent that I will be able to drive it alongside my other r/c tanks - nothing spectacular.

I will get hold of a pair of the motors that have worked for you so I can enjoy driving my HAYA Centurion as much as you do yours.

Thanks for your input as it sounds like it will be an easy fix.

That sounds interesting Meter Rat.

I am guessing that if these 390 motors are fitted into your Heng Long Challenger and T72 then they should also fit into my HAYA Centurion?

Do you happen to know if these are the same as the “blue” motors being sold by Toucan Hobbies currently on eBay “for Heng Long Ultimate 11 gearbox” .

If they are the same motor (just painted a different colour) it gives another supplier choice and saves the expensive shipping costs from Malaysia as the Blue motors are £14.30 for a pair with free shipping.

The "blue" motors are 380s of some sort or other. The "red" motors are 390s. Taigen's 390s are black with slightly more speed from what others have said. I don't have any of the blue or red ones so I can't comment from personal experience. HL made them blue or red to sell upgraded gearboxes to people that don't know anything about motors. You tell them reds are better and they will buy them or that blue is better than the stock silver motors.
HL Red or Taigen black, 390s are the same length. The 3 in the motor name is the class of the can, the 70, 80, or 90 is a reference to the length of the can/power level for the most part. There are exceptions to the rules, but those are what you should expect. The 70, 80, and 90 are an estimate of increased power, but the physical characteristics can vary.

There are definite benefits to moving from a 280 to 370 or 370 to 380 or 380 to 390, but as far as moving from a silver 380 to a blue 380 can be subjective. It is sometimes hard to find out what the specs are of these blue or red motors and some of them are just painted (IE: cheap copies and no better or worse than what silver ones are). BUT...all of these motors can be found in different configurations...as in emphasis on torque or emphasis on speed, or giving up speed and torque for a slightly smaller package. It's a bit of a black hole and you can end up wasting a lot of money on motors that don't do what you want them to do.
