1512 has more than enough torque to push a truggy. it is more powerfull than XL motor
it propels 13lbs maxx like it had a rocket engine while staying cool.

Maybe a Medusa 36-60-2000?

I read some things regarding the diffs, and I guess many didn't like the orings and had sealing problems. There are Kyosho gaskets tho that are a perfect fit and keep the diffs sealed.




I just got one too:yipi: but...... I screwed up the 10% coupon on ebay I had and didn't get it applied before I paid....:slap: <----me to myself.


i'm hoping he can cancel the sale so I can rebuy it. I was trying to hurry as my wife was giving my boy a bath and messed it up.....DOH!!!!!!!!

The Hyper ST is really common over here. I was wondering why there weren't any conversions. I'm going to be interested in how these conversions go as I may do one instead of a buggy but I would rather do a buggy.

Should be deccent, I would say that a 1512 would be slightly more powerful, but the medusa's have a great price. I have the 60mm 1500kv model in my hyper8 buggy and it does great.

Since I'm going with Masher tires, I'm going to use the 1515 2d instead of the 1512.

Ok guys, got my Hyper ST! I'm assembling the front upper arms, and what they call the 5x33mm turnbuckle I cannot find!! I found 2 of them, but they don't fit in the arms! The part number is 88079. Any help please!!

i have 2x hyper st 's

1x is 1512 2050kv with 14T pinion , MM , 4s temps perfect , great setup
other is 1515 2200kv mgm16018 with 13t pinion , 4s, again temps perfect great setup

both trucks run about the same speed (both with bowtie LPR ), the 1512 feels more punchy than the 1515 but i think that is due to the mgm poor programming ( as i dont have a usb com as yet )

im probly switching the mgm for another MM , as i think these are awesome esc's for 4s.

PS you will love the hyper st's ive had mine over a year and ran hours and hours on them and never broken or replaced 1 part !( but i think the centre diff needs a new bearing now)

Yep, I am very impressed with the quality of the kit, I'm trying to post pics but the f---ing USB hub doesn't recognize my card hookup. :grrrrrr:
Also, those rear upper a-arms are a bizznach and a half to build!

Have you considered direct drive?

:no:

think about it like this...

its one less Diff to build:rules::lol:

It's already built/installed. Curse my camera and these rear upper a-arms!!!!!
