somebody may have already answered this question but i didn't read all the post to find out. sorry i got in on the mini-t a lil late!! i plan on getting one of these lil boogers as soon as i find a way to charge the batteries with out taking them out every time. i want to run the orion 1800's and get a charger that will just plug into the connector for the radio. do you know what will work and charge in about 15-25 minutes?

thanks for all the help.....chris

I put the BRP turnbuckle upper link and tie rod set on the Mini-T today....easy install....they work GREAT!!!

I got my Hitec HS81MG servo in my truck, It came out sweet :thumbsup:
Should be able to wheelie out of every turn.

Bud-- so you took out the stock ESC -- what are you using?

Atom and a switch so I can run any freq. Hope it works :lol:

Bud, Are you using any type of servo saver?

Also, for those that are interested, I just got my set of XMod crystals. The cost is $15.95 for a set of 6 crystals!!!!

Using the stock one. I filed the ouput shaft on the 81MG to a hex was not too hard to do.

Pro-Line has a Crowd Pleazer Mini-T Body -- Part #3172-00 $13.00

So where's some links to all the aluminum parts and other hopup goodies like that.

I have been on BRP' site, they have some cool things as well. Good work Bud

Is your turnbuckles/tie-rods set, 4-40 or 2-56??

They are 4-40 2-56 is too small as is the 2 mm.

If the cups are 4-40 then, I was under the assumption that if you used a 4-40 ball stud that you would have to reamout the holes and use a 4-40 tap so the losi holes could be made to fit a 4-40 ball stud.

We include a thread cutting screw if you don't have a tap. 3mm which is what the stock ball studs are is very close to 4-40. Our tie rod / upper link set works out very nice !!!!!!!!!!!!

Joy wants a bumper #510, I think we'll both need a set of bearings #520. The turnbuckles #512 are a must! The stock rods bend VERY easily and turnbuckles are MUCH easier to adjust. Bud's shocks are made by AE and have threaded bodies, plus he includes all the hardware to mount them to your mini-T

Thanks Bud.

Another question.

I have the Losi 1100 mah 6-cell, 2/3 cell pack.
I have been hearing different info regarding charging discharging.

I have heard .5 - 2.4 amps to charge. For racing what should I charge at and what dropback?
Also should I be discharging these packs? if so at what amps.
Sorry I am new to the 2/3 cells.

Thanks

I'd like to hear Bud's opinion on this as well. One theory or "rule of thumb" that I've read is charge any smaller NiMH cell (AA, AAA, 2/3A etc) so that it will take an hour to charge. So a 1100Mah would be charged at 1.1 amp.

All I know is I charge them at 2 amps pulse with a old Novak charger. The ni mh cells I do not discharge to store. I do cycle a new pack several times and discharge them at 5 amps.

5 when you say several times is say 5 cycles enough to get them broken in?

I have charged my pack 3 times and each time it seems to get stronger.
so far I have used 1.5, 2.0 then 1.1 amps to charge and really havent seen a difference yet other than the time it takes to charge.
I have yet to drain a pack yet either even after running for about a 1/2 hour.

With NiMH cells you have to be concerned about getting them too hot. Charging them at lower rates generally will make them last longer. Discharging below .9V a cell can kill them. Leaving them discharged between long periods of no use can also lead to dead cells. I've experienced some of the above and learned the hard way. The newer KAN cells and a few of the new design NiMH are a different beast...
They act more like NiCds than NiMH batteries. In fact, the old 500AR cell was loved by Speed 400 pylon racer airplane guys and general airplane guys because of the high discharge rate and voltage. They were red wrapped cells and were about the only thing used in competition at the time. Sanyo's 600AE has a lousy discharge curve.
The KAN950 and 1050 are 2/3A equivalents in a NiMH battery and they
have higher discharge voltage than the 500ARs as well as higher current discharge characteristics with a very flat discharge curve. They can discharge at 20-25A rates without harm to the cell. The 500AR could do that as well but only had 500 mAH of capacity.

So, really, you have to know what kind of cells you are dealing with to know what kind of abuse they can take (abuse by the manufacturer is anything over the rated charge rates which are typically 1/10th of cell capacity for 14-16 hours.)

Generally I don't go over 1.5x capacity for charge rates unless they are designed for fast charge like the 500AR cells. You also have to let them cool to room temp (hour at least) between charges or you shorten the life of the cell. Depends somewhat on how much you are paying for the cell and what cost is reasonable for lifecycle replacement.

Well, I am partial to the Krystal3 motor from www.unitedrc.com =)

I am the tuner of these motors and all that I can say is that they are fast.

If you have any questions, feel free to ask. The retail on the motors is $25.

Do you need modifications for this to fit on the MiniT?
Do they sell new mounting plates?

yes you need to drill out some material fo rhte k3 to fit. but there are a few motor plates out for the speed 300 motors.

I really like the Ruby Racing Motor....It's a speed 300 size and will out perform the Orion big Block hands down! :devil:

Hey Micro Who Makes The Ruby? Is That What Your Running In Your Truck?

This is the link for the Ruby Motor..

http://www.kingdaddyracing.com/pages/1/index.htm

I got this motor a few weeks ago, but was waiting for the Speed 300 motor plate to come in from Country Alloy Works...

I raced a friend with an Orion Big Block, we both had the same AA cells gearing ect-- the Ruby was faster off the line and had much more top end speed. :wave:

I thought the Speed 300 was the hands down fastest in the Mini T from what I have been reading on other boards. I know they said its faster than the Trinity Monster and the Orion Big Block.

Those Ruby, k3 motors are just a speed 300 with timing advanced. Same motor though.

On my mini-t I installed a hi-tec 85mg for steering,a novak spy esc and a novak xxl rec. The truck is 100% better,turns on a dime and reaches top speed alot faster. I run the promatch battery,charge at 1amp and peak at 2amps,discharge at 5amps every race day. I also changed the stock pinion to a 16 tooth.My truck just seems to be getting faster every week.

What kind of pinions are you guys using as replacements and where do you get them.
We plan on running on our local oval which is 190' runline. Right now the thing winds out in like 10 feet.

i was just wondering if anyone in here knew how to figure out rollout.. I know how to figure it out with pan is it the same or what do i do??

MintRollOut = TireDia*3.14159/(2.71*(Spur/Pinion))

(according to my information, 2.71 is the internal tranny ratio -- other than that, the principle is the same as pancars...)

thanks

I am using the losi pinions,they come in 12,14,16. The stock one is 14. My buddy took and made a sleeve for the motor shaft and switched everything over to 64 pitch,makes the truck more quiet.

Joe
I havent looked at the gears, what are the stock gears? 32 or 48 pitch?

they are a metric 48 pitch.

Thanks Ron
Are there any replacement Pinion gears out there yet? Or do you have to use slot car gears?

Losi sells three pinions for it,they are 12 14 16. All three cost like four dollars.

i don't know what people are exactly doing, but here is a link to a delrin gear someone is running.

cool thanks

How was the racing at Freddies??
I should have our two new Mini T bodies by next week I think you will like them!

Bud,
Rob and I stopped out to watch the racing.
We never raced though. Wed will be our first night.
I think there were about 25 stock Mini T's and a couple heats of mod mini t's.
They run a heat of oval, then change the track for road course. 2 heats and a main of each.
Plenty of parts in stock over there too. You could probably build almost and entire kit with what they have in stock.
In the stock class there were alot of beginner drivers but the carnage wasnt too bad.
The one mod heat I watched was pretty clean with some good drivers.
I would bring a table to pit on. Cause most of the ones there were filled up.
Very nice facilty and hobby shop. And it was about 80 degrees in there so dont overdress cause they keep the heat on....
LOL

We also raced them on the high banks at Classic hobbies Saturday night.
We only had 5 of them but we had fun.
The only mods we had were foams, bearings and oil filled shocks. I think if we allow gear changes they will be okay with the stock motor. That or we may do something with the infield and make it a road course.

We have some new 3mm aluminum wheel lock nuts blue anodized #522 they should be on web site soon !!!!!!!!!

Bring them to the race Thursday!

I will have some there and they are now on the web site.

Hey Bud are you selling a shim kit for the mini-t?

We have some new 3mm aluminum wheel lock nuts blue anodized #522 they should be on web site soon !!!!!!!!!

Oh I'm sure K1M will have to have a set of those. He's a blue freak, be it parts OR nuts. :freak:

(according to my information, 2.71 is the internal tranny ratio -- other than that, the principle is the same as pancars...)

I just did a quick calculation of rollout using the 3 losi pinion sizes (12, 14, 16) and the spur gears they offer (58, 60). My foams are 2.1" so that is what I used for tire size

Tire Size-Spur-Pinion-Rollout
---2.1----60---12----0.487
---2.1----60---14----0.568
---2.1----60---16----0.649
---2.1----58---12----0.504
---2.1----58---14----0.588
