I don't know why you'd think the 8ight was faster than the CR(T). Speed is all a matter of how you set it up. If you are talking just lap times, there is no reason why the CR(T) wouldn't bring in as good as or better lap times than the 8ight(T). If, just getting the 8ight would make you faster, I think that everyone would have gotten one.

I like the 8ight, but having had experience with both, I'd take the CR(T). I find it easier to drive.

honestly,
lots of people are faster with a losi then they where with there jammin.
but they are harder to drive, they feel like rwd electrics.
while a jammin must feel like a 4wd nitro.
just my opinion

jolly,

I really don't understand your statement. The 8ight is harder to drive, but people go faster with them because of it? I like the CRT for that exact reason. The 8ight is harder to drive well.

I know it's dangarous to say such a thing, but i think it's all about tuning/balance/choice of setup/tires

if you take out all the nitro stuff and make it brushless the ballance is completely different than it was nitro.

it sounds weird to me that the losi feels like a rwd vehicle. sounds like the weightballance is too much to the front.

jollyjumper 05.04.2007 05:17 AM

well, i wasnt exactly clear.

first, you cuss and swear that your laptimes with the losi suck.
then you practise alot,
times will end up being faster then your previous car/truggy.
you gotta learn how to drive again if you come from a mugen, kyosho, jammin, ...
it feels like an rwd electric when its nitro cuz the weight bias is towards the front. it's quite loose in stock form,
you also gotta role the trottle where as on a mugen you can nail it quickly after the corner.
atleast this is what i read on nitro forums.
it may not be like that anymore after installing a BL motor and a big battery.
maybe mike and glassdoctor can explain it better then i,
for they raced there 8-t allready.

Of course...it is all about tuning, etc. It always is. I just found the 8ight harder to get to act right. The best that we were able to do was to get to a configuration that was better than the others we tried, but it still wasn't easy to drive. For me and my friend anyway.

Most of this is, after all, based on personal preference. It's just an opinion.

One thing that I've found that has made the whole electric conversion thing difficult is the weight of the batteries. Our track is very tight and rough, so we tend to run soft suspensions. When running such a suspension with a 4.8Ah battery, it's OK and we can tune things out to get the truck/buggy driving well; but when we need the runtime and move to an 8Ah battery and tune the suspension just to be able to support the added weight, the handling suffers.

AAngel 05.04.2007 05:22 AM

jolly, I understand what you are saying. Making a transition from one vehicle to another does involve having to get used to the new vehicle; but there are some vehicles that are easier to make a transition to than others. For me, the X-Ray is the magic buggy. The first time I drove one, I was driving it as though I had owned it for years. I do pretty well with a CRT too. I can't drive an 8ight worth a crap. As I said, it's just my opinion.

jollyjumper 05.04.2007 05:24 AM

i'm gonna try to stay as low as possible for battery weight/capacity.
i'm liking the flightpower evo 25 4s 3700mah, not to heavy and it can deliver plenty of power i think.

Serum 05.04.2007 06:09 AM

Yeah, with a brushless conversion you can't really look at setupsheets others use with nitro vehicles.

the entire balance is disturbed, most likely you need different diffoils, since the setup has got way more low-end torque. thicker oil (unless the setup became lighter, thinner oil would be needed) (in both shocks and diffs). I guess the differences between running a nitro and a brushless are quite large.

Arh, it's just a matter of years before the first xray/mugen/crt can be bought brushless ready...

jollyjumper 05.04.2007 06:39 AM

imo, we will never see a bl ready mugen or jammin. they dont even have any electrics in there entire line-up.

maybe xray, kyosho or losi.
but even that i'm not so sure of.

That is exactly what mike said after racing his 8 last weekend - he runs a bit of drag brake to help with the spin outs. But he did say the turning radius was absolutely insane (GREAT)..

Serum 05.04.2007 11:06 AM

turning radius is good..

Good thing i've got the mind of an elephant, i will gladly remind you to these words..

I've noticed a big difference in the diff fluids that I needed for my conversions. After a couple of months, I'm still working out the details with my Muggy. It was driving OK with the 30K in the center, 10k in the front, and 3K in the rear. I did bump up a bit after the conversion compared to when I was running nitro.

Yesterday, I got a bit nuts and went 100K in the center, 50K in the front, and 30K in the rear, and now it's almost driving like I want it too. I think I went a bit too heavy in the rear. Once I get the back end under control, I'll see how the front responds, but so far I like the 50K in the front.

jollyjumper 05.04.2007 01:37 PM

would it pull wheelies with 30K center?

1bhutch 05.04.2007 08:06 PM

it sounds like the 8-t is hard to learn to drive would it be harder to learn to drive the 8-t cause i have never drivena truggy cause i would be learning how to drive a truggy at the same time? also i was loking through mty magizines and i got caught on the mbx5t i like it cause it is just such a well rounded race truck. i also thought the 8 was faster cause i read a article about they got three truggs and they testsed them for a good time and they said that the 8-t had the fastest lap times.

also what about the walkera motor i think that the esc would be crap.
