Neu powered LSP video

http://youtube.com/watch?v=ldDo9bDGTlk

I made a mistake, that's 14/46 gearing, not 16/46.

hot bodies.

nice video but it seems overpowered to me.

How long did you guys needed to wait before the 'loading' message disappeared? is 15 minutes normal..? :p

Nicce video, it was a minute or 2 for me but I did watch it at 3PM GMT so I expect the Americans are still asleep.

I have been waiting 15 minutes now, and I just don't see it starting to work.

I just have one question. How is the True-RC 5s2p 8Ah lipo working out for you? The price is a lot lower than other lipo packs, so was wondering if the quality is comparable to other companies like Max Amps. I was originally going to get the Max Amps 4s2p 8Ah pack, but this has more voltage and is way cheaper. I am kind of leaning towards this one now.

Thanks.

TrueRC is just as good as Max Amps. Dan, the owner, is a really good guy.

Thats kinda odd. It only took a few seconds to load for me...

Mind won't load either.

My mind seems to have this same issues, must be one of those days..

short video from a gravel pit i found.. only 51 seconds long..

I uploaded the last video w/ a divx codec.. but I'll reup as a quicktime, and post the link so hopefully you guys can see it.

Thats a sweet video!! I think someone needs some new tires... you were sliding all over the place!!:027:

for anyone that couldn't see the first video, try this one:

yeah youtube deleted it because it had same info..
i edited the post, so try it now.

Yep, finally works. That thing is fast!! Looked to be a clean set up as well.

Sweet vid... Looks like that 1515/2.5D runss pretty nice. :dft012:

I'll second that. TrueRC lipos are a hell-of-a bang for the buck. Best value Lipos IMO. I have 3 sets of 5s 8000mah and they run great.

I second everything he says :027: (except the 3 sets part lol)

btw Jeff, I heard you went out to the Huntley track this past weekend. What do you think of it so far? Did you put the 1512 in your buggy? I'm thinking about skipping out on Hobbytown and see if I can play at Winne's instead.

Its even got a 2nd section of the track that can be added on to it if they want to make it bigger, or it can be run as a separte track. They are also building a dirt oval track, a big boulder pile for rockcrawling and they are even talking about putting in a scale dragstrip. The dragstrip soulds cool. I think I could get into that.

The layout on the offroad track is pretty sweet, but the place still needs some clean up before its ready to open. Really dry and disty with alot of big rocks still scttered about. Killer bashing spot right now, buit not quite ready for racing yet. Its gonna be really sweet when they are done though.

I wount be out there this weekend, but I'm gonna tray and get out there the next sunday.

Oh yea... And yes the buggy ran sweet in the 1512.

I want basically the same setup in my Thunder Tiger ST-1 Pro (1515 2.5d,Quark 125, 5s, 46t spur, 13 or 14t pinion for racing)
I haven't ordered the batteries yet though. I was thinking 8000mah maxamp packs, but people have been saying that the truerc packs are good value.
Are these packs getting hot in your setup, do they seem relible? If they work well for you then they should work well for me.
The packs are just barely warm. one of the packs slid across rough blacktop for about 60ft, and in my lsp, the pinion came loose, and moved up against the lipo. the cells have indentation where the pinion rubbed, but so far, no problems at all..
at one point i was running my lsp only only one of the packs (40a constant), and it ran flawlessly. the packs balance pretty well. nothing but good things from me.

How does the motor and esc seem temp wise? I don't think the motor should be much of a issue, but I'm not sure about the Quark.
barely above ambient.. It's been in the 70's, and I can't tell if there's heat coming off of the motor or controller/heatsink. I'm not sure about the quark either. I did the mod before I ran the truck, so I can't compare before and after.

How does the run time seem? I'm wondering if I can get 25 minutes racing out of it.
idea. I havn't run it down yet. I've been running for 5-10 minutes at a time, and basically I charge them when I've had 2-3 runs on them. I need to get a good long session in to see what it is.

Sorry, one more question to bug you with. What weight diff oils are you running? I like that it diffs out a bit, but is still able to do wheel stands.
Looks like a good car and I hope keeps working well.
Thanks
I don't even know what diff oil comes stock... the truck now has 50k in the center though. when I ran it before I changed the center, the fronts would expand to 10-12"

I can hear it it squeek, and seems to turn more to one side. Good to hear you like the motor. I like my motor alot more haha. great deal.

Very nice LSP IMO, I like that it has the power available there.

very nice set up seems to run very good.

Thanks for the answers A4DMT.
I got my 1515 2.5d yesterday, and I think I'll get the TrueRc packs (I want to use a 2s and 3s pack together), if there not that good then atleast they're not too expensive.
Now I just need to make a motor mount and battery trays.

I'm running a truerc 5S 8Ah pack too. With my 8XL it never even breaks a sweat.

IMPOSSIBLE! LOL!

My philosophy for RC's is like cars. Power is just about right when it scares the s__t out of you! :)

......and yes, if you can't control it it's not much fun, so I get your point. :027:

I finally got a change to watch the movie.

You are familiar that brushless controllers can do more than on/off?

You can see the batteries are getting warmer at the end of the movie. The temperature difference gives it more power.

I've always had horrible drivetrain luck with all my rc's.. my old tc3 snapped 5 aluminum cvd's, and bent two steel cvd's.. eventually went to titanium, and didn't have any problems after that.. I was just breaking in the drivetrain to see what would fail first. in the video the spur stripped.. I just happened to strip another spur tonight.. that's my 5th stripped spur so far :002: I've only got another 6 in my toolbox =\

What spur are you using? you could use a plate that holds the 51t ofna spur, and put two of them on it and ask Mike to make you a longer pinion. (or one plastic, and one steel)

I've been using the kyosho 46t gear from mike's store. I believe the cause is the motor not staying put.. it seems to slide away from the diff just a tiny bit.. I'm not sure, but it's not sheering the teeth off completely, it's just kind of flattening them 1/2 way down. I'm trying some new screws tommorow (hex head, instead of phillips), and I'll use loctite, and see if it holds.

You mean you are using philips head screws to hold the motor in place?

Sounds like you have another problem than a strength issue with the gears.. It needs to be tight in place.

exactly. I've got hex screws on it now, but I was running with a "dulled" diff gear last night, when it stripped. I'm off now to replace the gear w/ a new one, and threadlocking the hex motor screws, and I'll see if I can get it to hold up for a run.

You guys are putting loctite on the motor screws? I wouldn't even take the chance of any of that stuff getting inside of my motor.

I use the small 3mm lock washers and my motor hasn't slipped yet. That's the thing with these 6061 mounts. You have to watch not to tighten down too much so as not to deform the mount. I found this out with my 8ight mount. My homemade mounts were 7075 and allowed the use of the full size 3mm washers and I could really crank down on those.

Definitely! Without lok-tite, the screws back out pretty quickly. It takes about 10 minutes to loosen on a steel on steel setup. It lasts longer on a steel pinion/plastic spur setup, but still backs out. It's funny though; I've never used lok-tite on the Jato and it runs fine, but the Revo needs it. And I put about the same amount of tightening force on both (so the wrench twists about half a turn, lol). Go figure.

it's all in the weight of the vehicle. when I ran my rustler and tc3, I never used loctite.. not even on the pinion's grub screw.

on this truck, I need loctite on the pinion and motor screws, or else I can't get one run in..

all back together now, trying to get ahold of a buddy to help video it, w/ GPS on board..
went to 18/46 gearing, so we'll see if it does 40 like your calc says :)

From other people's testing, the calc is pretty accurate. Of course, it doesn't account for drivetrain drag, wind resistance, etc. And above ~45mph, the speed is derated due to a greater effect of wind resistance.

45.3mph.. I updated my LSP thread in the Brushless forum. I'll update this thread w/ a video when I get home later tonight.

18/46
