Fastest Truggy record?
 

Is there any recorded speeds for a Truggy? Just curious.

I just got my CRT truggy in and I might throw 6s and a big pinion on to see what kind of speeds I can get. :whistle: Then she'll be tamed down for 5s and track running.

Yep....And I'm still the unofficial holder. I should get started again lol.

What kinds of speeds are we talking about?

I only went 59mph on 10S. Would've went much faster if my truggy stayed on the ground lol.

My Vendetta ST went about that fast... Had a Neu 1107 in there with a 1/10th sidewinder esc. It was pretty quick.:mdr:

However, I never clocked it. It probably only went... like.... 50.:eyes:

I do have a video though!

Micro. We are talking about the big boys here :lol:.

I wasn't really trying too hard and I got my Hyper to 54mph, and my crt.5 broke 60.

Truggies should be able to do huge speeds considering they are so stable and well balanced. All I can say is if a rustler can do it, a trug should easily do it.

80+, go for it, lets see it.

Will do. I'm converting the Jammin CRT now. With the gears I have on hand, speed calc says up to 116mph... Doubtful on this number but it should be all of 80+, just hope I dont burn up the MMM.

As soon as I get it back together, I'm going to give it a shot.

I have a radar gun handy...

The most difficult thing will be finding the correct tire choice.

After seeing Nitrostuffer drive I think tire choice will be the least of his problems...:lol:

I beleive JZEmaxx hit 80.

Yes he did and he has the unofficial record for a Monster Truck.

Lutach - looks like we need to hook up somewhere to break some records ;)

I will have to see as I don't know if my daughter will go to Florida this summer. I will have to get back to it though to test the 10S 240A esc. I'm also trying to get a new battery for my TC3 as most of the lipos I've tried can't handle the 200A and 1.5T. One of my 2S 25C 5000mAh pack went down to 1.5V and the carbon fiber drive shaft seems to want to shatter lol.

Only issue is being able to gear up my revo faster... Truggies/gtp/stampede shouldn't be an issue...

I just don;t have a radar...

And you're much better?:lol:

I have the ability to gear my Matrix 20/52 on 6s zippy flight max... i dont know if I should or not.. No speed testing equipment


Wow.. Now that I check the speed calc- 14/52 on 6s gets me almost 80mph

Now I have to go home and test this :)

Motor should hold up- esc should too.. batteries are TBD

I can still get a 25T pinion as well...

6s on a 2650 is really not recommended tho...

However, I could try that as well, 6s on my 2650 combo in my Jammin X1 buggy...

This is true- but im sure it could handle it for a short time.

I see in jzemaxx's signature 80.4mph...

I have one... and a camera too :wink:

Camera's are a must... lol

Yep....80.4mph, actually its been faster, but not on camera. I did squeek out 86mph with no body on it. Also its under the MT class, but if you race a XTM MMT, you have to run it in truggy...go figure.

We also set the stampede record.

Quoting myself here lol.I don't think there's a battery out there that can supply enough power for this set up. I think lipos has finally met it's match. Here's what I'm talking about with the 200A and 1.5T motor:

Luciano- have you tried the SMC or TP 40C lipos out now?

I might contact them, but all this over rated lipos might not handle it. The one cells I'm trying to get a hold of is being used by the military and it's capable of delivering over 700A cont. and 1000A burst.

squeak...

:gasp:

I know :lol:.

Gasp Luciano!

just run two in parallel :lol:

Tried that too a few days before and without a Rx pack the Rx cut off and the voltage was at 1V. It was also kind of heavy lol.

I've run into a problem...

I'm using Mike's motor mount in my Jammin Truggy. I love it however, with the freakin ferris wheel of a spur gear(62T) I can only mesh a 18T pinion yielding not so favorable numbers for now.... only 73mph. I was going to try 22/88 on 6s first which should have yielded about 85mph.

However, I do have an extra center diff from my Jammin buggy(48T). So I will probably swap that in place and run 18/48 20/48 and then 22/48 on some speed attempts...

My eaglethree has mesured 63559 turn/minute in my st-rr with HPI Phaltline 0.44 meters of circumference gear 12/46

http://www.rc-monster.com/forum/showthread.php?t=20899

is equivalent a 101.8 KM/h

sorry for my bad english

Just made a couple quick passes with the Jammin, geared 18/48 with 13/43 diffs on 5s. This thing is insane and a torque monster. I don't know how to keep the front end down and the front tires from ballooning insanely! Unfortunatly I lost the damn pinion gear, so I'll be forced to run either the 20T or 22T next. Honestly I'm kinda scared to.

Thinking about putting some thicker diff fluid, or locking silicone in the CD. Thinking this will increase wheelies but kill some of the unloading. I can dial out the wheelies with punch control settings.

Just an animal....

That's crazy fast, man.... I like it! :yipi: It reminds me of my Rustler- Any increase beyond 30% throttle is like "auto tire-spin" mode, and it isn't just hitting the end of the punch control. Isn't excessive power fun?

I can't keep the damn pinion on. Lost it twice more, luckily I found it both times. I made a couple passes on 5s at 22/48 and its insane. I'll make a couple more passes and throw the GPS on it. I doubt I get any video, no one to video for me.

51.6mph was the best so far geared 22/48 on 5s. I can't make a good run without the damn pinion flying off. I've never had this problem before...

Any suggestions?
