Brushless Hyper st pro Build

[Pedebeater]

They are all great, including yours. It looks like your build went smoothly. Got any pointers?

[BL_RV0]

Yeah- before installing the polished steering plate, install the front brace.

[Takedown]

Whats the one part you got messed up on and couldnt figure out?

[BL_RV0]

Front brace...

[Pedebeater]

Thanks for that pointer. I will be sure to do that.

[BL_RV0]

Yep. Also the rod that holds the rear brace in also mounts to the wing mount- the rod was too short.

HAHA, I had mine before you did! Funny thing is that I will most likelt not finish it for a while. I have never really finished a truggy before I have sold it. And I have has 2 lsps, 1 crt, and some others that I can't remember. Just prefer MTs!!! I will finish it eventually, I actually like it better than the other truggies.

It seems that unitedhobbies replaced there feigaos with the new KD36 series, and customers have been having better luck. So I may as well give one a try.

Please let me know what you think.

I have a few of the kb45 motors and they are monsters. Well worth having to turn the shaft down to 5mm, and drill/tap the front endbell to the correct dimension. I will say that 5s on the 8l would be too much rpm, and that 4000 lipo would no be able to keep up. I run the 8l in a ofna gtp on 4s lipo (2 trakpowers in series) and they are almost not good enough. These motors are beasts, I have a 10xl waiting for me to put it in an aftershock on 8s....

The kb 45s do not really run hot from my experience, but they have alot of torque...

[BL_RV0]

So they're amp hungry beasts?

[Pedebeater]

That was another reason I backed out of the kb45. I need my Zippy-H pack to keep up.

[BL_RV0]

Yup.

The L can 45 can pull more amps than an xl feigao, but it also makes more power and runs cooler. I would take the 8l over a 7xl feigao any day, even with the mods required. I made my own motor mount for the gtp, so the 30mm mount spacing was no big beal. I also am running a plastic spur, and the 18 and 20t pinions that sdp-si sells were correct for the gearing. I have already lunched the front diff, but that was during a spectacular radio glitch induced front flip. Imagine this car flipping about 15 feet in the air for about 30ft and landing on its wheels!





I can only imagine what the xl 45 motors can do. I was going to run a cc hv85 with the 10xl on 8s, and am wondering if it can keep up with the kb motor...

I think that motor's spoon is too big.
The front diff said, "My anus is bleeding!!!!!"






"Ahhhhhhwwwwwww*choke*hhhhhh*choke*hhhhh.....!!!!!"

You got that right, I was doing over 40mph when the radio glitched, the flip was amazing. Would have made a great vid, pity I was bashing alone...

[Pedebeater]

I would pay to see that. I still think I will have to settle for the KD36-74, the thing better have preformence with that length. lol

Should be fine, just don't go mad with the gearing. Some trial and error will find the sweet spot that produces good power and speed with decent temps.
