And the build begins!
 

Sick paint rootar!!! Would it be possible to get a picture of the rear shock tower with the body mounts lowered? I love the way the "new" truggy bodies look.

I couldn't resist and I decided to do this conversion! :party:

Below is my parts list and if everything goes well I should have the truggy running in a couple of weeks.

XRAY XT8 2009 Spec
RC-Monster Conversion (Mike is working on a trick receiver box, it should be sweet!)
46t Slipperential
Tekin RX8 1550kv truggy motor
Hyperion 5s 5000mah lipo
Futaba S9351 (It's a spare servo with ~200oz of torque, will this be enough)

My truggy will be used only for racing. Where is a good place to start with setup? Shocks, diffs, tires, speedo?? Setup sheets?

Are there any option parts that are a necessity?

Anyone want to buy new nitro parts? :lol:

Hey feisty is he only making one or he is producing them

He said that he has a cad drawing of the receiver box and he just has to machine it, test it, and make changes if needed. Something like what he did with his D8 kit.

On a side note, how many people like the new style of body? It would be cool to have something like this for the XT8. :whistle:

WOW i LIKE THAT IDEA I DONT KNOW THE MEASUREMENT OF THAT BUT DEFINITELY WOULD NEED DRILLING TO FIT, I WAS LOOKING AT THE LOSI 2.0 BODY I BELIEVE ROOTAR LOWERED IT

He said lower the body mounts but you have to drill for the xt8 i still dont have a painted lid

Xray is working on a bulldog like shell so that part might be avaible from Xray.

Just a guess tough.

its simple to drill 4 new holes in the tower and lower the mounts ill try and get a close up picture of mine later.

I can drill the shock towers if needed. I just drilled my gorillamaxx chassis to fit a slipperential, it just takes forever. Triple check! :lol:

Does anyone know if Mugen MBX6-T bodies fit the XT8? I am looking at these two:

The MBX6-T has higher body mounts like the XT8, right?

EDIT:
Never mind http://www.rctech.net/forum/nitro-of...8-o9-spec.html

Anyone running the active diff's from Xray?

The JC punsher works great with the lowered Mugen rear body mounts. I just got one a couple days ago and trimmed it on the lines and it fit right up. No extra fitting needed. The bulldog works but needs to be cut weird in the back to clear the shock tower. A buddy of mine has the buldog on his XT8 and I diodnt really care for the fit of it.

Here is a picture of the mugen mounts on my xray for whoever it was that asked for a picture.

The active diffs work, but to me are for very specific situations. I have them but dont use them very often. 90% of the time I much prefer running the 41T overdrive gear on the front diff and the slipperential in the middle.

The 41T gear really makes the truggy turn in like crazy and accelerate straight out of the corners. Really like it alot in most situations. Makes my truggy feel like driving a buggy.:mdr:

Thanks jhautz!!! That is exactly what I was looking for. Is this the body that you used? http://www.jconcepts.net/store/index...roducts_id=355 I am tweeking waiting for my parts from RCM! :lol:

You can use the active 41T gear on the stock diff? and it helps turning in the corner?

Any other setup tips that your willing to share? :yipi:

I think that jhautz is talking about this one: http://www.amainhobbies.com/product_...Bevel-Gear-41T

not this: http://www.amainhobbies.com/product_...Bevel-Gear-41T

Ahh Thanks.. I didn't think to look under the buggy. I am going to have to try this if it helps turning..

Yea. That's the gear. Makes a huge difference with how the truggy turns in off power and how it exits the corner on power.

The other thing I'll say is don't go to high in the diff oils. I run 5/7/3 in mine and love it. I see alot of guys running alot heavier than that and it forces you to dive alot more agressive to get the car to handle. Of course that is just preference.

I had a friend of mine that drives a losi 8t test my car out last weekend during practice because I was turning some really fast laps and he couldn't pull the same times. He took the wheel of my xt8 and on his second lap around the track beat his best time with his car by a full second! Needless to say he bought an XT8 the next day. Lol.

The XT8 is a machine!

Rx Box/servo mount.... cool stuff Mike!!

http://i66.photobucket.com/albums/h2...9/XT8RXbox.jpg

Indeed! I just finished building my XT8e with the new Rx box and it is such a clean setup! Great job Mike!

Is that your truck jhautz? What spur gear are you running on the slipperential? What is a good setup for shocks? The stock setup seems really light!

My truck. Used to be JHautz's spare xt8, but I got tired of him and another xt8 guy beating my SLowsi 8t 2.0, so I doubled down and picked up an xt8.

The slipperential spur is Mike's Delrin/plastic spur. 48t tooth. Running 6s/1400kv buggy motor. Works really well and very effient. Running less than 200mah/minute which is phenomenal in a truggy.

Cool! Thanks for the info! What battery are you using? I bought a 5s 5000mah Hyperion and the dang thing wont balance properly (3rd cell goes over a .25v difference while charging). Hopefully I will receive a replacement in a week or so. Could you possibly shed any light on suspension setup?

I really don't know yet. I have only had it on the track once and I had no idea what oils were in the suspension. I haven't had enough track time with it yet to be able to offer any credible setup advice with the xt8.

I put 35wt in the front and 30wt in the back with blue springs. Still trying to figure it out myself!

Truck drives good though and I think it will be dialed after a one or two more race days.

Handles much more like a buggy than my Losi. Turns in on a dime and is very stable. I can push it much harder and it seems to actually handle better the more I drive balls to the wall.

I am using Hobbycity packs. Normally use a 6s 2650 or 6s 4000. You may want to check your charger settings to make sure it is calibrated if you are getting one cell charging too high.

That happened to me on my 6s packs, I would get one cell over charging about .2 volts. I figured out it was the charger and there was a way to calibrate it.

I checked the manual for my charger (Thunder Power 610C) and I didn’t see a calibration settings. It was actually .25v below the rest of the cells and the charger would have a temper tantrum and stop the charge. My 2s and 3s packs charge fine and are balanced. I also verified the packs condition with a volt meter so the charger isn’t crazy (I don’t think so at least :lol:). The manual recommended charging at .5 amp but I still had the same issue. Because of all this I am fairly sure it’s the battery (just a fluke and my luck). It’s ok though, Mike is taking care of it for me. I can't wait to get my truck running!

Check each cell individually with a voltage/multimeter for verification.

Yep, I did. It would get more out of balance the more mah you put into the pack.

I'm running 46T slipperential, a 1550 tekin motor and 5s. 15T pinion for small tracks and 16T for big tracks. Ive been stuck on this motor battery combo for a long time now. It just works so nice I cant bring myself to bother with trying oher setups.

I actuially like the light stock shock setup if its a rough track. For smoother/higher traction surfaces I go up about 5-10wt front and rear and then go 1 spring heavier in the front. (purple I think)

:grrrrrr:How come you guys have the radio box and I cant seem to find it there is one that says D8

These are very first couple Mike made to prove out the design. He should have them listed soon. Design is done now I belielve. He just needs to machine up a batch. He might even have done that already. Not sure. Maybe Mike will chime in and let you know availability timing.

Swift, are those UE Supershocks you are using on your XT8, or Ofna Ravager shocks with UE Progressive Supershock Springs?

chad they are UE supershocks on the xt8 the mbx6t is stock

:yes:Definitely hope Mike puts me on the list for one of those asap when they are ready LOL thank Hautz

Thanks for the info! I will be running a electronics setup very similar to yours. All that is left to do is paint the body. I can't wait to race this summer!

I have a question I dont race for now but should I put mechanical brakes for the xt8 or mugen
they say it is mostly used by racers what u think I dont race yet

Nah, mechanical brakes just complicate things and clutter up the chassis and layout. ESC/Motor brakes are more than enough, even for experienced racers. Generally, nitro people who have just switched to brushless try out mechanical brakes on their new brushless setup because they are used to the feel of mechanical brakes, and are afraid the ESC/Motor brakes won't work for them. Once they try the ESC/Motor brakes, though, they eventually ditch the mechanical brakes because the ESC/Motor brakes are far easier to adjust, have much more adjustment, and literally never fade or wear out.

The radio boxes are showing as an option now - we have one for the D8/D8T and the RCM XT8 now(will also work on the RCM Jammin SCRT10 chassis when it is released as well). :)

:yipi:Thanks Mike just finished ordering it I feel better now.

You mean the Jammin SCRT10.:wink: The SC10 is the Ofna truck.

Jhautz care to comment on the mechanical brakes and are their certain settings i have to do on my dx3s and the MMM as far as setting for them 41t 14p

I played with mechanical brakes on both truggy and buggy for quite a while and in the long run didn't ever find any advantage on the track. Once you get used to tuning the motor brakes and adjust your driving style it is just as fast as the mechanical brakes IMO. There are guys that swear by them though so it really is a matter of opinion and what you like.

Unfortunately this kit does not allow for mechanical brakes. The provisions are not made in the motor mount so... Lotsa work to get that set up on this XT8 conversion kit.

If you are asking for my personal opinion... I tried it all and wound up with the simple and consistent esc/motor brakes.

When you race with a MMM2200kv in a truggy what brake setting do you use?

I haven't used the MMM for a long time and I have never run the 2200kv motor.

The way I tune my brakes is I start off with more than is needed. Then I dial out brakes until I can just lock up the wheels when hitting full brake at the end if the fastest straight. That's all the brake I need and it makes for a very controlable setup for me.
