Excitment abounding John, can't wait to see them.

I´m really anxious to see how your sensored outrunner turns out to be. are they going to be in the area of your other outrunners, size- and powerwise? Is scorpion going to produce them?

I hope the new outrunners will only have the diameter of a 540, as the crawlmaster, but they will be shorter than 60 mm. I liked the dimension and weight of the old crawlmaster too much so I'm ready to buy anything which looks like it.

JRH, are you conscious we need a cheap and bullet proof sensored esc too ?

I am very conscious of the need for a sensored controller too.

Scorpion is one factory I am considering. Each factory has tooling and capabilities that are good for certain motors.

The first plan is an outrunner that is slightly smaller in diameter than the crawlmaster, but the normal length of a 540 motor. I see that the short motors would be wanted as well, so I will likely release a stubby version too.

Aussie Nerd · 02-23-2010, 06:18 PM

If you could make a stubby outrunner for around $50 and a sensored ESC for $100 or just over that would be wicked. And if you could match the speed, torque and smoothness of a 7t puller I would buy at least 2 and maybe up to 4 of everything

Oh and please make sure that the drag brake is better than the goats too.

wow...ive been into brushless outrunners for planes, helis, and boats.... and have used sensored systems for my fast cars...... but now you have just go and mix it all up...lol j/k good work keep it up

the smooth motor start up will be great for those "holy crap!!" moments, the brakes will be smoooooth and we will really see a difference with our exponential and drag brakes.
motor cogging results in loss of runtime and excessive heat.

its gonna be tough to figure out sensor position and esc sensor compatibility due to the amount of poles inrunners have compared to outrunners. rite??? would a regular censored esc push a modded sensored outrunner due to the increase in poles?? i know that outrunners are really rough running when put too far outta timing. can blow an esc fast.

i guess all you can do is try try try....rite?

ive been through and experimented with alot of esc's.. may not be able to tell you what to do....but i can tell you what not to do!!! lol

Hi John,

did you talk to Lutach about this?

Your and his mind combined, imagine the power!!!

whoodie · 03-10-2010, 07:02 PM

Any news John? I'm about to throw all of my brushed motors away, cutting comms was so 2009

Aussie Nerd · 04-12-2010, 04:48 AM

How are these going? How did the last proto turn out?

X2 I keen to hear an progress

JohnRobHolmes · 04-18-2010, 10:40 AM

Nothing new yet, but I have another proto coming to me and updated sensor boards in development.

John82601 · 04-28-2010, 11:24 AM

Update?

JohnRobHolmes · 05-13-2010, 01:32 PM

Dissapointment :( The motor was no different than I could make myself (think hot glue and loose sensors), and one of the sensors wasn't even soldered in properly.

Now you guys see why this thread is so damn old? Multiple prototypes, and still no factory that can get it right.

Sorry to hear.
