Skaldiddog's "Progress"

[SkaldidDog]

Wouldn't lathed cans be smoother on the bottom end then stock cans?

Yes once rolling. See JRH below. He was correct in his interpretation of my comment regarding low end. Maybe pre-low end is what I should have said. I love the heavy brake and quick response.

So you aren't using the Holmes Hold...just the standard drag brake I take it. Thanks for the response 8)

Standard drag brake.

That's funny, I do the exact opposite. You can pull the trigger about halfway before there is any response.

I like to see my truck lunge forward with the shaking of my nervous finger. You should try it. Jokes aside I've seen guys do it both ways. I like a very low trigger weight so that she goes the instant I need her to. I'm impatient.

How are you going to mount your mini's? I've just left my BR-SL open to the air and lashed it to an electronics plate with lacing cord. But I'd like to shrink wrap the mini's and servo-tape them down except for the suspicion that it would contribute to heat build-up. Somehow running no heat-sink and wrapping them up in a plastic cocoon just seems wrong.

I'll coccoon mine but in a slightly different manner that I've not yet seen. I'll post pics and all will let me know if the idea is original. Hope they arrive in the mail today.

I'll be wrapping them up in a cocoon "thumbsup"

I've been running BR-XL's, Mamba Micros, and Sidewinder Micros like this for quite some time now in different rigs and haven't had the first issue related to heat. I think heat will only become an issue if you like to run full battery packs back to back. Most of the 2.2pro rigs are running something like a 450mah pack so you'd get something like 15 minutes of run time...usually less. So unless you run 1 pack - 15 minutes and then pull it off and throw in and run through another pack - 30 minutes I don't think you'll have any problems with excessive heat.

Agreed. The SMP's get a lot hotter than BRSL's. Will be interesting to compare the minis.

Heat moves faster through the power and motor wires, they are the effective heatsink. The Minis have such a low resistance that it isn't an issue in a comp rig. Wrap em up!

On startup-I think that is what Joel is saying too. Stock 540 cans have better brake, and more abrupt startup.

Depends on whether the thinning effects back iron circuit permanence coefficient (PC) or zero current airgap flux density more. Second order effects can be measured directly. If %KV increase is more than %loss in detent force the startup is worse. Ceramic magnets in a 540 are weak and thick enough, and airgap is small enough, that startup gets better going from 50 thou to 25 thou can thickness. Below this thickness startup gets worse while KV shoots through the roof and detent force falls only slightly.

These rules don't hold up in brushed motors when the KV is much faster than 2100, as brush losses start to dominate the circuit model and applied voltage for startup rises. This is for a regular copper standup or laydown brush. Larger brushes like the P-94 allow for slightly faster KVs before brush losses affect startup.

Damn chinese is what all this is. John will be holding class at Nats. I'll bring a grease board and a lab coat for him and sit back and learn.

With standard Blk shrink OK?

Sheepskin condoms work best.

That's what I was thinking...

熱移動通過電源線和電機快，他們是有效的散熱片。的的扭蛋具有這樣低的電阻，這不是一個問題，在一個小樣圖鑽機。裹舉起手來！

在啟動時，我覺得這就是喬爾說得太多。庫存540罐有更好的剎車，更突然啟動。

取決於是否細化效果背鐵電路持久性係數（PC）或零電流氣隙磁通密度。二階效應可以直接測量。如果％KV增幅超過％的損失制動力的啟動是雪上加霜。陶瓷磁鐵540弱的和足夠厚，，和氣隙足夠小，即啟動50你25你可以厚度得到更好的。低於此厚度啟動變得更糟，而KV射穿屋頂和制動力僅略有下降。

這些規則不抱起來時，有刷電機的KV速度遠遠超過2100，刷損失開始主宰的電路模型，並施加電壓啟動上升。這是經常站立或沉積銅刷。像P-94允許較大的刷子刷前虧損影響啟動速度稍快的KVS。

I try to keep as much mumbo jumbo out of it as I can, its tough explaining why without it. I did withhold Br, bd/hd ratios, hci, and all the other factors that are primary forces in a magnetic circuit.

Xlnt. I might as well get some tube on order while I'm waiting for the mailman. Is 1" OD before shrink x 1/2" OD after shrink the right size for the mini? Flattened out, it should be about 1 1/2" wide before shrink.

Thank you kind sir for sparing our brains the additional chinese. I've done some reading in this area but do so infrequently and quickly lose understanding.

Got any comprehensive primary literature reviews for me to look at. I need to brush up on my Chinese?

Dexter mag has a pretty good FAQ for light reading Magnetic Theory and Design Frequently Asked Questions - Magnet Solutions from Dexter Magnetic Technologies

Browsing the TDK website for articles is also a good resource. Most magnet manufacturers have enough literature to educate, like how IC instructions hold your hand for the entire circuit design.

Nice finish yesterday Joel. Good luck today in the Finals "thumbsup"

 

[Erik D_lux]

WOOT WOOT!!!

Nice job Joel!!

 

[TEDROCKZ]

Congrats Joel"thumbsup"

No one told you that Bergs were dead:lmao:

 

[michael]

Congrats! Nice Job man...."thumbsup"

 

[Crawllife]

Congrats man! Love seeing a berg up there!

 

[Erik D_lux]

Congrats Joel"thumbsup"

No one told you that Bergs were dead:lmao:

Somebody forgot to tell Joel and 3rd place, Kevs G.

BIG win for Berg and NON 8* steering :ror:

Edit:

AND a big win for the 1lb worth of knuckle weight club!

 

[EverettY]

Congrats on not only National Championship win but the Ottsix VooDoo Challenge as well "thumbsup"

 

[Hildy]

I am glad that you took the win. From what Ive seen you are an awesome dude and a great help and informative member here on RCC!

Its funny because I was on the phone with my buddy winnerone23 this past Friday and we were talking about how good of a driver you are.

Excellent job and well deserved

 

[Jslick]

Great driving Joel!! Congrats on the big win!! Rock'n the VOODOO

 

[Red Rockcrawler]

Congrats Joel

 

[Hittman]

Congrats Joel! Way to kick some ass while rockin the Voodoos:twisted:

 

[boosted4lyf]

A much deserved win Joel, congratulations sir.
It's been great getting to know you over last yr or so, thanks for helping me out this weekend.
Glad to see this go to such a humble, and genuinely great guy"thumbsup"
