I think our soil here is DG and clay plus a little sand. The California Gold Rush started right near here, down the hill from us. The area my track is in used to be a pear orchard. Maybe that's why there aren't many rocks or stones. Just good dirt. We just drove our cars, they "made" the track. Here's a couple pics....

RustyUs

Ah, yes EXT2Rob. Your dirt reminds me of North Carolina dirt (some places).

While I wait for parts to finish up power supply, I got to digging in storage boxes... It's time to let go of some unused items while thinning out the RC stable. I hate to do it, but I have to let go. I keep telling myself..."I've done it before, and I can do it again".

I made a micro flex ramp.... but realise my truck out flexes my crawlers lol

RustyUs

I spoke too soon. Ruts have taken at least one stadium truck out of commission.

RustyUs

Today, I did what I said I would never do again. I vowed I would never get rid of another RC. I always seem to have seller's remorse later on. One of my "shelf queens" is on it's way to a good home. . I feel good at the moment. I didn't cry or nothing . I'm on a roll now. I gotta grab another box full of stuff.

phmaximus

hahaha, if only.... I like to think I regret some of the ones ive sold... but... sometimes u just get sick of things and need a change

once I had a fair collection of 1/10 to 1/5, now ive only got a handful of micros and a couple of 1/10 cars. but u know what... No regrets... life changes

Well, I put up with it for the last time (3S LiPo) tonight. After waiting for it to finish balancing....two + hours.... it never happened. One cell had outrageously high internal resistance compared to the other two cells. It (the one cell) would reach 4.2v long before the others, and always the lowest voltage cell after LVC kicks in. The "bad" cell's voltage; charged @ 1C rate, and started from storage voltage, would ramp up very fast to 4.2v while the other two cells were somewhere near 3.9v.

Anyways, I drained the pack down until my light bulb discharger didn't glow anymore. I was waiting for hardcase to break. I heard it cracking as the pack was getting hotter, and hotter. I thought maybe I'd catch something on video, but nope.

Again, one thing gets fixed, another problem comes along.

Last night, I ran the SC10 hard. The motor bearing (inside) started seizing up, and I didn't think much of it. I actually thought it was the newly transplanted ESC needing calibrated, because every time I'd let off the gas, the truck would be braking hard. I kept on running the SC10 like this for a couple of laps until truck would go no more. Went over to truck; picked it up; I'd give the transmitter WOT and the tires would just nudge forward a bit, but nothing more. Then I smelled that smell...motor was freakin' hot!

Today, I pulled the motor out. Bearing failure was the issue. Took forever to get the bearing of the rotor. Screwdriver wedging, along with vise grips proved to be the right combination to overcome the bearing. Then I thought I possibly bent the shaft with all the bad language I used under my breath .

Motor back together again...I started to mount it back on my truck. This is when I saw the melted spur gear. Last night, as I hurried back to the garage for some compressed air to cool motor down. I know the motor was hot, but no idea of it being hot enough to allow pinion gear to melt spur gear.

RustyUs

I got the SC up and running again. LMFAO! My low $$ blue brushless motor screams with power once more. For as much abuse as it takes, I'm surprised the motor runs at all. The rotor has sooo many nicks/scrapes/gouges from me trying to get bearings off of it. You would swear I was using dirt as a lubricant if you saw the crap that comes out of the motor when I'm disassembling it.

One test run, on B4 buggy, with new V2 shock bodies, and they are holding up so far. No more o-ring clamp to worry about!

I will note, the same above test run for the shocks lead me to finding tranny diff outdrive bearings starting to seize up. So it's B4-buggy-rear-end-maintenance-morning in the good old Commonwealth of PA.

Evader ST sits in corner of garage...waiting to recover from owner's poor driving misjudgment .

i aded my own center weight discusion

RustyUs

I was curious to know what kinds of amperage was flowing through my 1/8 scale buggy since the first new Bias battery UNI connector failed. So I strapped in my watt meter to do a ride-along. Second run with the Bias LiPo 3S pack, with the UNI plug still on, proved to me that they cannot handle high current flow. The two pieces that make up the UNI plug, plus my Deans, got melted together when I was only pulling 83 Amps from the battery. I couldn't get them stinkin' things apart.

Thanks to server power supply conversion, and having to make some charger leads with XT60 connectors, I now have a love affair with the XT60 connectors. Little bit of rain outside giving me the nudge to get this done....

Printing out parts for my DM1. Working on making it lighter and less bulky.

Got my HobbyWing brushless system installed in my 1/10th redcat blackout xte. QuicRun 10bl60 esc and QuicRun 3656 motor, under $100 shipped for everything I needed to convert, not including lipo. For being considered a budget system it completely hauls a**. I don't see why someone like me (not a racer or highly experienced) would ever need more power than this. The improvement even on nimh was surprising, but the battery was getting way too hot because it couldn't supply as much juice as the esc wanted so I bought a gens ace 6500 mah 2s lipo. The esc will actually go to 3s but I
don't see the need for any more power. Or damage to components. For the whole truck with upgrades, battery, and smart charger I think I'm in less than $350 for a screamer which I'm pretty happy about.

RustyUs

Sounds great! I'm curious to know, what motor you ended up with?

My phone is being a piece right now. Anyways that url is what I got, I had to buy off ebay though, about $40.

Right on, Sledder! Glad you're stoked. Hard to go wrong with Hobbywing. Happy that you got a Gens Ace Lipo. I hope it's a 2S1P, rather than a 2S2P. Have fun!

Solder dude, solder!

RustyUs

99% done with connector swapout. Sore finger tips from all the heat-shrink removal. Three ESCs and my bulb discharger are about all that remains to change over to the XT60.


A day and a half of de-soldering 40 plugs; soldering 38+ plugs, and while binge watching TV series, makes quite a bit of mess. My soldering station sure got a work out. I wasn't sure if it was up to the task or not, but it has worked out very well I must say.

The number one reason for swapping out my Deans...the size. XT60 connectors just give me a little bit more surface area to work with; allowing me to easily grab the XT60 with thumb, and index fingers.

Deans, and I had a good run together. Today our relationship is no more . My EC5 connectors were swapped out as well, because they are, IMO, just a pain to deal with. This is especially true if you ever want to reuse them. Bye-bye EC5. Your time with me was short lived. I won't miss you .

Sledder9

It is a 2s1p.

I did notice today that the three wires from the esc to the motor, the connectors are getting pretty hot. Seems odd they would do that, I'll habe to do some research

My Feedback: (1)

If there's one thing I've ever had issue with on Hobbywing systems, it's some of their wire connectors. I think once in a while they don't solder them properly, and a high resistance connection develops. It can get hot enough to melt the solder. If you have a wire like that, it's best to replace the connectors, and do a good solder job.

Sledder9

Problem is I can't do a good solder job either. The connectors feel solid but of course I can't actually see the solder joint since it's got heat shrink.

Total bummer this weekend...

I've broken something every run I've made with my 'new' scratch built TL01b. At least now it's nearly all aluminum.

I burned up my new brushless hobbypower combo last weekend, this Saturday I stripped out another spur gear and that 1 was aluminum. All I had left was the speed tuned gears from my tl01a so I put those in the truck to at least get 1 run. As soon as I got it out the steering servo started acting up (futuba high torque ball bearing) then 5 more minutes the silvercan motor finally called it quits.

currently I got 2 R/Cs (the tl01a has never been run, I was either waiting for parts or stealing parts to keep the Tl01b going) but now I don't have any functioning motors, I was really happy with the Tl01b with brushless but not sure if I should just hang it up and stop blowing money on it.
