Boolean21's StreetJam OTA-R31 RC Drift Car

Had the OTA-R31 for quite some time liao... and here's some photos to share on my newbie drifter...

The bashing shell....


The shell from Master Liew...


The internals...


during last week's drift meet, realised that the rear differentials are slipping....
so i took it out and followed Drift Master rtech's method to re-locked the rear differentials...
by using 3x 2mm bolts and nuts...


running on HobbyKing 60A brushless combo


thanks for looking...

With this rear diff mod, it will not slip anymore forever.
If possible use softer springs for more control.

Yes master... I dun think it will ever slip again...
I will practise harder...

bro if u ever have any intention to let go those black Rays Engineering TE-37 wheels, let me know 1st!

updating my RC diary......

ran the StreetJam OTA-R31 drift car during one of the recent adhoc night drift meets....
and broke a bone.... old cars.... bones get weaker...



removed the broken part...


and ordered a pair of new CVDs from Eagle Racing... recommended by our resident Drift King - Rtech...




got a few lengths.... was recommend to get the 48mm length


replaced the broken part.....


and swapped out the ok one as well.... just in case....


now the OTA-R31 is ready for the next night drift meet again!

thanks for looking!

A little update on my Street Jam OTA-R31 drift car...

During the last drift meet, the steering jammed up after going over the track marker... and spur gear was worn out...

Didn't have tools on site to dismantle the car so managed to find some time to check on it...

Noticed that the front left wheel didn't turn smoothly....
So, opened up the left hub....




Realised that the universal joint broke... which caused the steering arms to get in the way of the spur gear and in turn... worn out the spur gear... :'(

This is the previous set of 48.5mm from Eagle Racing as well...

Here's a close up of the "crack"
 

This time round, I've ordered 2 sets of the universal shafts in case it breaks again!
No idea why it keeps breaking... could it be due to no servo saver in place to absorb the shock of the wheels going over the track markers?

Sounds possible... maybe I should add a servo saver into the OTA-R31...


Here's how the poor spur gear looks like now...

  

Ordered a spare for this too...

Meanwhile.... the Street Jam OTA-R31 shall take a break while waiting for parts...

Thanks for reading!

[REPAIR] Streetjam OTA-R31 - Broken universal shaft and worn spur gear

During one of the previous night drift meets, the front left universal shaft broke and jammed the wheel and steering, causing the steering arm to get in the way of the spur gear.... and in turn... the spur gear was worn out...

Parts arrived and it's time to get it ready for night drift meets!
Ordered spare universal shafts as well... just in case!




Added a servo saver to the OTA-R31 as well... hopefully it reduces breakage of the universal shafts...



Replacing the spur gear...
 


And the universal shaft....
  


And now, the OTA-R31 is ready for the drift meets again!
