guys, what is general concensus about mks servos?had nothing to do, surfed their site, micro servo, 0.05 sec @6v, a bit better torque than savox 0257 or hitec mg65...(freakishly expensive but 0.05sec!)

than quite affordable hv standart size servo with more than 400oz torque and 0.09sec...

my grandfather all so got me into this hobby i remember building gliders from an early age. we used to build everything from paper airplanes to boats to the big gliders that were made from balsa and powered by rubber bands
god rest his soul

If you are talking about the MKS DS95-i, they are a little bigger in height and may not fit in the wings of the 48 EXPs. They are expensive probably because they are coreless, digital, chrome-titanium, heli servos, and heli servos need to be precise enough to synchronize. Ir's not that you can't use them in airplanes, but the only time I saw them used was because they were less expensive then the airplane counterpart. They probably get $90 for them because they may be the inexpensive competition to the very expensive JR.

Aside from perhaps being too deep and too expensive, the torque is no better than the $25 analog 65MG at .11 secs, or the digital $32 Savox 0257 at .09 secs... and the $32 Savox 0255 has something like 14 oz-in more torque than all three. The 65MG's are even cheaper on HK now too.

What does Coreless mean?

They accelerate faster... coreless motors have a rotor that is made without an iron core, which means torque is only exerted on the windings.

So is there basically empty space where the core would normally be?

From Wiki... I've never analyzed one myself.

The rotor can take the form of a winding-filled cylinder, or a self-supporting structure comprising only the magnet wire and the bonding material. The rotor can fit inside the stator magnets; a magnetically soft stationary cylinder inside the rotor provides a return path for the stator magnetic flux. A second arrangement has the rotor winding basket surrounding the stator magnets. In that design, the rotor fits inside a magnetically soft cylinder that can serve as the housing for the motor, and likewise provides a return path for the flux.

Flux? You mean the flux capacitors, right?

but the whole point of using them would be that torque is comparable to 0257 ormg65, but they have around double speed... but yeah, thinking reasticially, only place would be aelerons in EF planes... so technically, they have comparable torque, double speed ,(should) have excelent centering, and double the price...


but about savox 0255... i think i will convert my mxs rudder to 0256, which is WAAAAY slower, but nearly doubles torque of 0257 and testament of its strenght to me was that it survived 2 times when i landed my 42" on rudder...

Only if you're building a time machine, Dr. Emmett Brown.

Current and Flux are interchangeable terms in physics.

if i didnt have so many hs65mg's or a set of 5065mg's i would love to give these a try

This isn't a 3D plane, and its not a EXP, BUT!!, it is powered by a torque motor and ESC package so I thought I would share..

Most people don't know, That torque motors come with a solid prop mount, and a shaft collet adapter as well. It's very easy to use your torque motor for many applications by pushing the shaft through the body, and using the collet adapter. Because the torque motor is so versatile you can use it in your 3D plane, a high wing, or even a warbird like I did. I even checked over the application, and believe it wouldn't be a problem to mount one inside a PA style motor box.

Thanks to my 820 KV torque motor, and 45 amp air boss speed controller I was able to build a Fast, and reliable stunt jug. Because I saved so much weight, I was able to run retracts, that add to the performance when closed. Torque motors always help you to take it to the next level!

Next time you're picking out a motor for another manufacturer's airplane , take a second Look at torque motors. Extreme flight carries motors for almost every application!

Check out my video it was filmed in one long clip, no edits from takeoff to landing, And I'm pretty sure there's a few moves in there that you've never seen a p47 jug do before. Having four ailerons mixed with the flaps helps a bit..

Parkzone p47 "One trick jug" (5 min 45 sec)

Btw, Cody's high wing stunt trainer was the inspiration for this project.

Totally sick, Tim.

how can you say no, when a kid is begging you to try airplane saying that dad lets him fly helis... im thinking next time i see him,ill let him taxi around...(or a stupid idea? maybe beter let him crash a crak yak to prove that he cant fly? )

He will probably be ok if he can handle a heli, but I'de sure use a buddy cord.

The weirdest thing I ever did was teach a deaf heli pilot to fly airplanes. He was a really good heli pilot and he picked it up fast..... once he learned not to push the stick forward in level flight like you do to make a heli go forward.

He could not hear me when, or look to read my lips when I would give him instruction. Worse, he kept pushing down elevator to go up, and there were several really close moments. In the end, I soloed him after three flights.
