It turns out I am just an Idiot. I was used the way the .21 motor would scream at top rpm and was trying to get the same from the .28. All is fine now motor runs strong has lots of bottom end to accelerate the tall geared mammoth to 52mph in no time flat. thanks for all your tips and advice.
you need to make an 8 port .28 that will scream like the .21 dragon motor.

Break-in the dual STS28 SAVAGE.

Wheelie when break-in...

It is glad that the engine is under control now.

Dino, does the savage use the original drivetrain? what about the driveshaft, dog bone? diff set? anything change when use with this engine?

i love the video...especially when u all playing under the overhead highway

Is this engine fit mugen MBX 5 ? I mean the engine mounting.

As I knew if you enjoy wheelie then you need some upgrades. Otherwise you don't need to change anything. But I knew it is hard not to pull wheelie when you have a lot power.

First you need stronger rear rims. Aluminum rims or change the hex-adapter to bigger one.

When you pulling wheelie the clutch bell is very hot. And the pinion gear is very hot,too. So it will melt away the plastics spur gear. So you need to have a fan to lower the temp of the clutch bell if you are a wheelie fanatic.

Also you need a 5th wheel fitted on the rear bumper. See the attachment. That is very important! You will damage your engine's cooling head if you don't have the 5th wheel. STS28 has too much torque. When you kick down the throttle the car just backward somersault.

Because it rains almost 2 weeks here. So we can only play R/C cars under the overhead highway. Now is rain season in Taiwan

It should not have any problem. I also install a .28 on my X1CR. I can tell you that it is the beat practice engine for buggy. The engine has much more power than any modified .21 engine but its price is very economy.

Dino,

Did you have to modify your X1CR for the 28 motor?

Thanks.

Hi Phong,

You need the one-piece engine mount. You can get it from OFNA.


Thanks,
Dino

Hi Dino. I have an sts .28 on the way to me and I am looking forward to trying it out. I have a question about your savage.... What gas tank is that and where did you get it? Looking forward to running this engine
thanks

Hi rcosmax,

Sorry that is not SAVAGE. It is RAPTOR.

Dino

Ahhh. I thought you had found a replacement hop up tank that solved the savage tank probs.... Anyway looking forward to running it this week.

a fan to cool the CB?? thats totally cool...but dont know how to mod into the savage

the 5th wheel is like the trolley wheel. OMG
