Jordan, your tires are spinning and a lot of weight is toward the front= no wheelies. You need to run on street and lock your CD and wheelie central...

I agree. If you lock up the center diff and stick to running on asphault you can try for some high speed. I am not a huge fan of wheelies, but you may need so shift some of your weight to the rear for that.

Sorry about that. I had an HV spirit get in my body just now .

Kind of an out of body HV experience we assume. Just don't start chanting.

I didnt change the setup on my truck from when i bought it. and on 4s it would scrape the rear wing on the floor. when i stripped the diffs there was grease in the cd. i think if you lighten your truck you will see wheelies. try running smaller 3s packs for 6s

[SV6000]

Hey Jordan did the calcs and found out that my overall drive ratio is 8.9-1
I looked at the calculator and saw that if i add the truggy diffs it will work out to be about 13.5-1 and if i drop my gearing down it will go to 18.92-1, a lot safer. By the way the top speed with 8.9-1 is 82mph drag adjusted

[jordan...]

8.9:1 ey , you have run it before right? did your speedy get hot? From Shauns gearing i reckon around 15-16:1 seems about right. 18.92:1 would be alot safer, but make sure you dont go too far and undergear it, then the motor might start getting toasty. Drag adjusted of 82mph, thats insane specially with a 1515 Keep us posted with how your changes go, have you got the RCM hybrid diffs on your truck? Im assuming you have the buggy diffs in now?

[SV6000]

nope got the standard erevo/revo diffs in it. yes i have run it a few times i justput 50000 in the CD 30000 in the front and 7000 in the rear to get it to handle better. it will still wheelie to my hearts content but not as easy as before. i will have to get the truggy diffs in it soon to take care of the speedy but so far it is doing fine. the only time i got it to trip the fuse was when i was putting it through its passes on 4s. i had it in an area about 3x3m and was making it wheelie non stop from one side to the other for about 5 mins straight. as soon as i hit neutral on the tx it reset and was fine. it would run better with better batteries. at the moment i am running maxamps until my flight powers arrive. i think i will put in the truggy diffs and play with the gearing to get some middle ground

Nice to see the truck running well at last, its been a long old build. On the cvd issue, you can buy a device called a 'bone saver' (anyone remember that conversation, one for the history books..) that you can use to extrace and replace the broken pin with, if the press doesnt work.

good idea, what voltage are you going to be running with the Flightpowers, still 4s? I think i'm going to try 50000 in my CD, and maybe 75000 if that doesn't lock it up enough.

Thanks Neil. Ahh yes the bone saver, i was searching through the arcives and i think i saw something from '06 on that? Definately has been a long build, pretty much exactly 12 months, time flies when you're having fun i guess

Hey Jordan..

It was great to see it starting to finally take on speed!.. I'm sorry to hear / see your current issues. On the positive side, now you can prepare for this repair in the future as well to cut down on (down time). Example My truck has a few weeks points and I've learned them so when it brakes I've got spares, now you know a week point of yours too so it’s kind of good thing (sorry just trying to positive spin a shitty situation!) LOL.LOL..

Best of luck Jordan..

P.S.
It’s an awesome build…

Thanks Shaun. The speed is getting there, still would like it a bit quicker, but im working up to that. I'd rather that than just stupidly fast straight away, and two stripped diffs and broken driveshafts. At the moment i dont think that that was a weak point on the truck, more operator error I musn't have tightened them up enough, thats whay they came loose. All the other corners held up ok though, so thats a plus. Hopefully with some thicker diff oil it'll gain some punch off of the line.

I dont think outright speed is that great anymore. I have an inferno GT that does 112kmh (checked with radar) and its still nitro I think i will get the kyosho 777 conversion kit from castle and put a 2200kv combo in it with 6s, just to see what happens
I think in a MT about 40mph is quick enough for bashing and racing, but in saying that i think i will have mine set up so that i can change batteries and pinion and do one or two quick 60-70mph runs, and than let the speedy cool down hahahahaha

[jordan...]

Well i just gone done stripping down the truck and checking bits and pieces after its first proper run. Apart from the broken driveshaft pin, i found one of the grub screws in the stub axle of the right rear cvd had come loose, and the pin which holds the stub on was half hanging out. It scraped a little gouge in the back of the knuckle, but no real damage and an easy fix. Apart from that, all looks good, i've gone through and loctited all the pillowballs, so hopefully no more sheared pins. Instead of a drill bit, im going to press out a pin from a spare centre dogbone to replace the cvd pin, should do the trick, unfortunately it probably wont be till the middle of next week. Also replaced the CD oil with 50000 wt. Can't wait to have another run to see how it handles now!

Well the good thing about having to go through your truck like that, and make repairs like this is that you become even more familiar with your vehicle and how it responds to your mechanical ability as well as your driving. I think that we all run into little issues like that after doing such a big project. Things just get overlooked no matter how hard we try no to. Plus there are teh rare failures of parts that we have to expect. I am actually planning to strip my entire project down once I get it finished in order to redo all of the harware and loctite everything that needs it. I have an entire stock of titanium screws for it when it goes back together. I am trying to leave nothing to chance with this one.

Exactly Jerry, never hurts to be too careful. You say Ti screws, i've heard that Tony's 12.9's are a little stronger, but the Ti screws will definately be a little lighter.

As for the Xray diff mount and the HB diff, i got them both from amainhobbies.com. Although now i am running an Xray centre diff. Here are the links to what i've got on the truck now:

Centre diff

Now i am running a 48t spur, not the 46t that comes with the diff...

what a fricken pain.. I'm sorry sir but like the MAN "Jerry" said above at least you have yet another opportunity to go through your build.. Hopefully you'll get it all worked out soon enough..

You will like the 50k center diff, what were you running before 30K??

Have a great weekend Sir..

P.S.
I still think you should order up a spar T-bone..

[jordan...]

Do you mean the centre dogbones Shaun? I've got two sets of those, one stainless steel from RCAlloys, and one hardened steel from Mike I was running 30k before, it tamed the power down nicely, but im aiming for a little more crazy this time. I was expecting little hiccups here and there, another couple of runs though, and everything should be sorted. I also think that the batteries will gain some performance when i put a couple of charge cycles through them, still on their first at the moment.

[BL_RV0]

That sounds good. Get a pavement run next!
