I also broke a front upper and lower arm at the track today. Of course I launched funky off a small double and smacked a 4x4 piece of wood on pit lane. The arm did split down the middle right at the pins, but honestly any buggy arm would have broke the way I hit. I also broke the front chassis "brace" part number ofn29302, but again another freak thing. I was using a t-bone racing front skidplate/bumper, it caught the dirt on a bad landing and snapped and downflexxed the chassis enough to break this part, screwed my steering geometry up and was really hard to finish the race, but I finished third.

So far I have ordered enough parts to keep me rolling and I love this buggy.

had an issue with the set screw that holds part 29315 ( a little block that the center diff rear cup slides over), it was pretty stripped from the factory and I can't get it out. I'll be sending in that portion of the car after the race this sunday to see what ofna can do. Other than this, a leaky rear diff (had a similar issue with my RC8FT when new, maybe pressure change with shipping?), and the fact that whoever did the threadlocking looked like they spilled it on the front of the car it went apart and back together nicely. I like how easily the shocks assembled, and they are huge.

I went with the stock mounting location for my electronics. I removed the big outer casing that the speed passion ESC uses to get a better fit on the ESC mount plate. Here are some pics I took with electronics mounted. Rear pic showing the answerrc toe-in plate. just need to finish up the beater body. :

I've broken a front arm too (same split as everyone else - at the inner pin).

Apparently Hobao are working on a new design front arm.

Marvin,

can you post a pic of the breakage?

So by the sounds of it, this buggy is doing pretty well other than the weak front a-arms. Would a truggy motor fit in? Or is it too long? Is the battery tray pretty secure and strong? Is it made out of plastic?

Cain · 06.02.2009, 06:02 PM

the battery tray appears to be quite sturdy. Only thing to watch for is if you use long packs, the wires may bunch on the tray as its higher up than other trays.

I am excited to see what this thing can do.

Here's mine :

Medusa 60mm 2000kv, 14t pinon, 4S 6000mah lipo.

Gonna try to run her tomorrow.

well I have had my first issue with the speed passion ESC. Didn't even get to run it. :flaming:

Had everything all set, ready to go, and when I went to turn it on, the switch was VERY loose, just tapping it would kick it on from on to off. Tried it a few times, and off it comes. Great... And since the switch is integrated (3 wires), I am not sure what wire can I splice together like you do on other cars to get the power to just stay on when you plug the battery in. Very dissappointed. Had to install a Mamba Monster 2200Kv setup in the vehicle which barely fits.

Here's the crappy power switch:

I am sending this to shawn and see what he says. If it is possible to splice the wires and they will still warranty the ESC, I am willing to give it a try. as it sits now though, I am going with this or I won't be able to run:

I liked how the speed passion setup went in the vehicle, but I am very dissapointed on how the switch just came apart. I got contacted by Shawn about the switch, and he is going to send me out a new switch and I can splice the power wires together to get my by. Just need to confirm which are the power wires to be sure.

As for the 2200Kv, I fit about a 15T pinion, don't think I can go smaller unless I grind on the motor case some.

The 2200Kv has A LOT of torque. Need to play with the settings a bit for this.

jhautz · 06.09.2009, 09:03 PM

So what is the front and rear diff ratio on this buggy? A friend of mine has one on the way and we are trying to figure out what motor to get for racing on 5s. I'm thinking 1400kv Tekin. Not sure if you could gear it down far enough on the 1700 and 5s.

Can anyone tell me the f/r ring and pinion sizes. Thanks.

gixxer · 06.09.2009, 10:29 PM

I believe its 11/43. I have the 1400kv in mine, but I run it on 6s geared 17/40. Its more then I need for the track and ended up with the punch at 3-4 on the tekin esc.

Marvin · 06.10.2009, 05:14 AM

It's 3.909090909 (or 11/43 as gixxer says).

By the way, I've just sold my Hyper 9E. Not because I don't like it, but more because I just don't keep cars for that long. I did like the handling, though durability appeared to be an issue with it. Also, I kind of like home-grown conversions more, you can put your own personality into it. So now I'm building a D8!
