Life changing events

[DrKnow65]

LOL, sorry bro, I thought about just putting up the hyperlink and not the photo's but some guy's get a rise out of it... Glad to hear you've get the ins thing covered :)

Some people are just unreal in their greed, I'm constantly amazed ( and feel the same about them as when you see the pic's of my hand, LOL :)

Here are some choices so far:

Neu Motors

1527/3D 770Kv (Will be almost at the RPM limit)
1527/3.5D 660Kv
1527/2Y 625Kv
1527/2.5Y 500Kv
1527/3Y 420Kv
1521/2Y 780Kv (Will be almost at the RPM limit)
1521/2.5Y 630Kv
1521/3Y 525Kv
1515/3Y 725Kv (Will be almost at the RPM limit)

Mega Motors

ACn22/50/3 710Kv
ACn22/45/3E 800Kv

Lehner

30xx

Kv from 404 to 808

2280

Kv from 411 to 822

1950

Kv from 418 to 836

Plettenberg

Bolido
HP 370/50/A1 S
HP 370/40/A2 Heli
HP 300/40/A3 Heli

The right motor will depend on the SHV controller. I will try to keep the RPMs between 30000 (For normal running) to 60000 (For speed runs).

Once again DrKnow sorry to hear about, and now SEE your pain. Cool photos. It could have been much much worse. The best thing to hear is that you are approaching this from a positive perspective. Too many people go into some sort of depression and spiral downward in the aftermath of such a disaster. Like I have said in other posts life marches on no matter what we do. So keep your chin up and stay onboard the life train. Even through all of our suffering we still have to manage forward motion and happy days WILL still find their way into our path. We can tell you are a good man and that will always be followed by good things. Best wishes to you and your family through all of this.

Your engineering ideas sound pretty cool. At least you are finding ways to remain creative during your recovery. I am just about to update my life changing events thread as well. I am back home in Belgium and ready to move on with our lives parenting my three small children. Good luck to you man and keep your spirits up.

Man, what happened to you is like my worst nightmare. Just this past week alone I logged at least 6 hours on my scroll saw, I'm glad that's done for after seeing your hand!

I really hope your recovery goes well. We're all rooting for you.

[suicideneil]

Whats that noisr you make whe you see someone getting really baddly hurt on a youtube vid?.... Gruwhuhhh! Nasty business.

Anyway, regards the BL motor idea, I believe there is a company producing AC induction motors that dont use permanent magnets, but at the moment they havent made anything small enough or suitable for RC use.

Im interested in the new engine design idea- if that works out you wont have to worry about working much I imagine

Oh, and just to add insult to injury, have you seen this Drknow? http://www.sawstop.com/

I know, I know, Im an evil bar-steward. I wish you a speedy and full recovery man, I would hate to loose any use of my hands, and someone who relies on them for work (like you do) would miss them even more. Get well soon.

With that being the outcome of an argument with table saw, u better watch what u say around your lawnmower; bad idea!

[rchippie]

Sorry about your hand, but it looks like you got off lucky.

[DrKnow65]

Got off way lucky, a moment of not looking and bang, it's done...

MetalMan, what were you doing on the scroll saw for 6 hours??? (building something cool out of aluminum I hope...)

Suicideniel, I've seen some of the stuff about AC brushless motors, but it does look far off for it to go RC...

Dang Luatch, you've looked into the low KV motors!!! What do people use to spin those motors now? Are there already esc's that will do over 40v?
P.S. did you ever try a TCS cooling system? I was looking at some old posts and saw you had interest at one point. I'm thinking about doing a stage 2 mod to my MM with a liquid cooler sandwitched between the boards (pressed for room in a 1/10 buggy I'm running, very little air flow without perferating the body)

The most lipos I've heard or seen was only 15S. The lower Kv motor will produce more torque than the higher Kv ones. I forgot to mention the Neu 22xx that might fit the bill as well. I will be putting together some form of liquid and Peltier cooling system. I already found a few manufacturers of mini water pumps. I've also spoke with a couple manufacturers of Peltier devices that can custom make them to fit around non finned motors. All I need to do now is find a source for the radiator (Water cooled heatsinks) for the ESC, motor and the whole cooling system. I'm still trying to figure out the most reliable way to go about doing it.

[DrKnow65]

Can you post a few links for the pumps you've found? I see the TCS pump but have had no luck reaching them for more info. I'd like a cost effective alternitive to the TCS pump.

I will search my e-mails to get the data sheets of them. It might take a day or two, because I contacted the manufacturers a long time ago. I usually keep my company's e-mails organised, but I have no clue where I put the e-mails I got from them .

Edit: Here are 2: http://www.alita.com/dcpump/micropump.php and http://www.chinamicropump.com/

I will have to search for the others as I contacted them in 2003.

Wow, best of luck with the recovery. I burned my hands on a fixed gill pit at a park when I was young, took almost all of the skin off both palms. Luckily I was hit by a car the year later and have no memory of my chilhood (8yrs and younger). I have very little hot/cold sensation in my hands, but have devoloped much stronger tactile sesation to make up for it. That is handy as I do auto paint and body work and it is very handy (pun?) to be able to feel the surface for imperfections.

I really hope that you get better and regain most if not all use of those fingers!

If I had a monkey butler he would be on his way to you, but the ASPCA took him away

[DrKnow65]

you keep me smiling lincpimp :), damn though burn hands, hit by car, monkey removed... I'm feeling bad for YOU now :) You rewound a motor, did you read the idea about a brushed/brushless hybrid? think it would work?

Luatch, I have also looked into those pumps, the tube style one looks too big for RC (65mm long) and the chinamicropump does not sell straight to the consumer... Looks like TCS is stil the best bet. Just no response and expensive for what it is ($68 plus shipping, if that is even current info).

Wow, that saw stop thing is pretty impressive. It's $69-89 for a replacement cartridge each time the safety mechanism is used, which I guess is cheaper and easier to buy than new fingers.
One of our woodwork teachers in high school was about 60 and had been doing that sort of work for probably 40 years, but he put one of his fingers in a table saw at school one day, so anybody can have simple mistakes like that which turn out bad.

Good luck with your hand, and those inventions. Maybe you'll be able to release your motor before the mmm motor

I'm searching for the quote I got from them. It's funny how things seems to vanish when I try looking for it, but when I'm not trying, I can find almost anything . I might use the long one for my chassis, as it will be ong .
