I will have the full range of pinions here by the weekend - should be enough to hold tough for a while - they have been moving quite quickly for sure, but I have several hundred gears on the way. :)

And I can make a battery tray specific to your battery on request - my design is pretty universal, so it can be made to fit most any vehicle. :)

Dafni 10.31.2007 02:55 AM

Word!



BTW, the pinions hold up real good. No visible signs of damage yet.

How much would you charge for a battery tray?

Trever007 10.31.2007 09:50 PM

Hey Guys its been awhile seince i posed because i have been doing all this on road stuff and carpet racing. But i was wondering if any one of you guys had a Jammin X1CRT, Mugen MBX5T or a Losi 8ight and a XRay XT8 to compare and tell me what you like better. (i will be running at barn stormers) Thanks guys!

DeLarge 10.31.2007 10:00 PM

Well I cant coment on the electric versions but I will give you a basic rundown on the Nitro versions. The CRT is heavier and the oldest, it is still a great truggy but the newer ones are more popular, probably for good reasons. Then for the MBX5T and XT8 they are my two favorite, I favor the Xray because of quality and I think they handle better too but I have never driven one to know, Then you have the 8ight, not my favorite, although it is a good car it is harder to drive, if you get on the gas to early in a turn you will do a 180, just a bit harder to drive. But you might want to look into the ST-RR from the three times I have seen one run it looks to be amazing, it turns way better than anything else, it just looks dialed, you might want to consider one.

squeeforever 11.01.2007 12:18 AM

I kinda like the looks of the new Hyper ST Pro.

nl12 11.01.2007 08:27 AM

what gearing are you running?

Sower 11.01.2007 12:24 PM

Well I have a brushless equipped X1-CRT Pro right now and just ordered the XT8. I won't know how they compare until I get it set up though. I will say that the Jammin is very durable and a great truck. I have mine setup with a Neu 1515, MGM 160, Flightpower 4s 25C 5000 (also an extra Hyperion 4s 4350), and Airtronics 359 servo. The XT8 is longer and seems to have better materials as well as better handling from what I've heard. One thing I didn't like as much about my CRT was it's turning radius. Not as tight as the new 8ight-T. Hope that helps a little.

cadima 11.03.2007 11:10 AM

Yo Sower, been a while.
I haven't driven the other models mentioned but they all look good to me on the track. I can comment that the CRT is tough as nails, but does need some mods to make it turn with the best of em and you need to dial it in from it's stock settings. You'll need to reduce it's width between the wheels with no-offset rims and 5-6mm offset hubs. This brings it in line with an 8T. You'll also need to trim back the steering stops on the front hubs to get more swing on the tires. This brings it up to speed. Haven't found a truggy yet that out does mine on the local track.
The 8T layout makes for an easy to balance conversion though.

Just my 2 cents...........:neutral:

i think your rc..

Dafni 11.04.2007 04:41 PM

Blimey! You must be right :lol:

(I was asking because there were all those other conversions mentioned.) :oops:

Anyway, I use 18/46 for 4S and 15 or 16/46 for 5S on that motor.

I installed a nice heatsink on the motor since those last pics, btw.

Hey, what's up cadima? Yeah, I've been here but not always posting. Since getting my CRT pretty much dialed in with my MGM/Neu I haven't had anything to post about really. Thanks for the tips on the CRT tuning, but I just bought a nice XT8 that will be here Thursday. :party:

I'll be selling my CRT as a whole package pretty soon. I have to replace a CVD so I'm waiting on that. However, this XT8 I've got coming is pretty sweet. Comes with upgraded aluminum hub carriers as well as some wheel extenders and 0mm offset rims. I'm pretty stoked about it. Great to hear from you cadima - your conversion is still one of the best ever. Just awesome!

cadima 11.05.2007 02:45 PM

Dafni,
I am working on a version 2 of my CadimaRT conversion, and am studying weight distribution. Looking at your xray conversion, seems the weight is biased towards the rear quite a bit. Can you comment on how the handling is? Have you been able to compare it to the nitro version handling? Any input appreciated. thx!

Dafni 11.05.2007 02:58 PM

Hey Cadima, what's up?
You are right, the XRays by nature have a more rear biased weight distribution than most other truggies (and buggies too). On the truggy it's really apparent, the front being stretched like that. Just look at that link on the steering servo.
When Mike and me were working on that truck, we kept wondering how it would handle.
Because I studied some nitro XRays I wanted to keep the battery that much to the rear. Similar to the nitro engine and tank. Mike told me to move it forward, I said I could still move it later on, basically trial and error. But when it was finished we were both amazed, first try definitely felt like a hit. It has very good on-power steering, and the off-power is just unreal. At first we tested it on the lawn, Mikes' frontyard, steering was real good. And on the track it's the same, turns perfect.
Somehow the trucks geometry works very well with the weight biased like that, on the track and in the air too.

Beautiful ride, kleen kleen kleen. What's the runtime with the 5s pack and speed?

Hi Daf,
Wish I could understand the relationship......Kyosho and Ofna are both pushing things forward on their upcoming releases. I am an off-power fan myself and that's what I am pursuing. Thanks for the reply......

cadima 11.05.2007 08:51 PM

Daf,
One more Q.......... does your truggy have one of those active front diffs? If so, curious how they work out. thx again.

No. (or not yet) The active diff they released will only take the buggy reduction so far. Apparently the truggy version is in the works. I don't really see why the ringgears should not be interchangeable, but that's what they say on their forum.
That thing looks good, doesen't it? Might finally be a torque sensing diff that could hold up to some power. I'll make sure to get one for my XB8 AND the XT8 too, when they come out.

Thank you!

I'm sure Mike can make one for you if you send him an email!

drkros3 11.06.2007 03:08 AM

i think i well do that. thanks.

Hi guys. I’d like to build one brushless XRAY buggy .Can I fit NEU 1512 fined motor to RC-Monster motor mount? Thanks.

I'm sure you can - especially when most guys run a 1515 in the truggy. I'm pretty sure the buggy and truggy chassis are basically the same, aren't they?

I'll be sure to get one for whatever truggy I have as well!

Keep in mind the XRay diffs are different than most other buggy diffs, the bearings are closer together. Not much, but still.
I bet it's the same for the active diff.
You could make it work in some "regular" bulkheads, I'm sure. With spacers or something. There has to be a way, those active diffs look very nice!

Daf

cadima 11.07.2007 09:52 PM

Now Daf, do I come across as the kind of guy that lets a few mm's stop me?:lol:

That's good info to have, though. Shame they can't all just pick a standard size.

Certainly not! I have seen some of your prototypes at the monsters lair :yes:

It's just that at the ringgear mesh "a few mm's" are a lot, I had to point it out while we were at it :lol: (XRay diffs are similar to Mugen diffs, btw)

nl12 11.08.2007 08:42 AM

Dafni are you saying Xray diffs will fit in a mugen?

Dafni 11.08.2007 08:47 AM

Most probably yes. I will have to check next time my MBX5 is open, maybe tonight. But I'm quite sure they are.

Daf

nl12 11.09.2007 10:02 PM

I am really liking the XT8, I have no money for one, too many other projects. I will get one of those active diffs for my MBX5T project if they will fit, the truggy version should be out by then.

cornolio 12.01.2007 02:22 PM

2 mambas
 
hi, im just new here. How do the double mambas work for you? Are they reliable? Where can i get one? Thanks

Sower 12.03.2007 11:27 AM

Well, here's a few photos of my XT8. I got mine on eBay and it had been raced three times. The guy put some nice hop ups on it as you'll see in the photos. It came with the black anodized aluminum front knuckles as well as the rear uprights. Also, all the steering blocks have been replaced with the aluminum ones. The front chassis brace is aluminum but the rear is plastic. The guy also made some nice CF mud guards that attach to the rear suspension arms. I also have the RC-Monster motor mount and chassis brace on it right now as well as the servo piece. I'm working on a revision to the mud guards so they're not on right now. Well, here it is:

on the forums the guy "griffenru" does the mod.

entjoles 12.20.2007 02:04 AM

i just got one of these and was wondering if anyone knows if i can flip the center diff so that the motor is in the front , opp. the steering servo, thanks

Jan Donga 01.14.2008 10:27 AM

What a nice and clean conversion. I am planning of converting a XT8, but still dont know what motor & esc i should use.
But i did drop my eye on a Lehner 1950/6 HiAmp motor.
Do you guys think that the XT8 can handle the power that motor delivers?

Greets

Jan

nl12 01.14.2008 10:45 AM

Jan, the power output really depends on the batteries you use, but yes the XT8 would have no problem with that lehner.

Thnx for the fast reply.

I have two maxamp 8000HV 4S2P 14.8V lipo's.
What esc do you recommand? Because i cant make up my mind about MGM and Schulze.
