4535 "Paw - Edition"

[Bladecpnitro]

Awesome work Powercroco. I wish I had something large enough to try a 4535 Paw Edition in my self. Maybe one day but right now I'm content with a 450 and a 550.

This thread made me start to like electric motors! Amazing how it's built.

I'll try to get one of these Paw edition motor to put on a 700 that it's on the way!

You will not regret it, just get a 200A ESC and GOOD batteries. More power that a 700 head can absorb!

it's possible to wind a single motor this way for sure - but the danger for hurting the wire insulation in winding process is very big and it takes a lot more power and time to make it.
for my guess there was no way to wind 100pcs. in this wire diameter and into an acceptable time range.
using 1,7mm was hard enough....

Ralph wow my utmost respect for doing such a large job. Amazing.
I got a chance to wind a masterpiece 4+4 1.8 version myself, just one
Actually I found it relatively easy? Ok for the back muscles its perhaps wise to wind not too many of them...
The key lies in the stiffness of the isolation plates and since I make them myself (0.9mm thick in this case and properly chamfered) I did not have any issues with isolation damage.

bert,


you are right!
to wind the first of them is very easy also for me as for every experienced winder.
but it's a big difference, if you make one motor and this only for your own pleasure or if it becomes a bigger project.

wind 3 one by one, and you will sleep well. and you will feel, how concentrations goes down
wind 20 and you will feel the fingers and arms.
wind 100 and you will have fat horny skin plates.
wind 155 and you will feel good, when the last is done and you can do another things again after fullfilling your promise.

this is not only about winding, but also for preparing the stators for winding.
not sure, if you have refiled 300+ insulation plates in a row.

the hurting danger is the glass plate itsself independent how thick it is.
in these motors are used 0,9mm thick plates.
but the 1,8mm wire is able to injure the paper while pulling it around the rounded corner.
and when you then pull the wire direct over the glassmaterial and if the wire arc will not stay as round as you want into the winding process, you will get scratches into the wire insulation. this was the main problem.

interesting is also the wire quality - I think, you also have used the better type, what was reglowed after passing the last honing plate.

and now add the almost not feelable by the pilot difference in performance between 1,7 and 1,8.
and add also, this all was not a bussiness, but "only" a pure charity work..........

Hummmmm so powercroco is Tony Stark??

I flew the 4535le on banshee on 21t and 14s, flies well. Swapped back to 4530le 500kv on 21t 14s, bogs a little more than i like (flying extreme) and affects the tail to much regardless of settings.

Flew the paw motor on 14s 23t on banshee on andrews banshee and had a blast! Power is really smooth and strong

Tommorow we fly back to back 4535 500kv and 450kv paw motors on the banshees

Id like to see some more paw motors in different kv eg 500 or 550 to use on 14s. Maybe for tdr2? Perhaps we can call it the helicraze edition haha

[helicraze]

My my my mr ralph. In 2 days we did 3 motor swaps. By far the paw motor is the nicest

The biggest suprise is how smooth and strong the power is and the tail is so locked it improves any machine in regards to how it flies! This motor is sensational and im amazed at the difference it has made in terms of tail performance and smoothness

I have noticed it sounds different also in flight?

[powercroco]

thanks for your work and comment!

it shows sometimes again, that heli pilots do not feel efficiency, but only torque.

but as I just said, the main thing isn't the theory, but the feeling of the pilot in flight.

now you only need to test a 4535 in 0,1mm plates and 14P can - I think, it would be the peak.
it combines the wanted properties of 14P motor with the higher efficiency of 10P and is also 2-3 grades smoother in running.

[helicraze]

Ohhhh really? That motor sounds interesting. You know ive bought probably over 20 le motors. I would love to buy another, especially if such a rare piece is available!! Ive got a masterpiece 4535 (that killed a new lipo with over 400amps haha) which in keeping for tds probably.

If there is a way to test your new motor id love the opportunity.
Otherwise maybe i need another paw motor. But id really like a rare piece for my tds or new banshee

I really cannot describe how well the paw motor is. Because the tail doesnt kick around it makes the whole heli feel better. With 24t im sure i could go 2500rpm or more but personally i dont run more than 2400rpm on banshee.

we will try and do a video shortly

[powercroco]

I have checked it - still have one of these 0,1 stacks into my storage, but no "PAW"- housing.
I think you know, that such stack alone is more expensive as a complete "normal" motor.
It a really "nice to have" part.
I built with such materials in 42xx, 45xx and 50xx size and I personally love the results and prefer to use such motors into my own speeders because of the high efficiency and the very smooth running.

unfortunally you live on completely the other side of the world.....

[helicraze]

Hello, im sure our friends at scorpion can help us.
Let me know what you require for this to happen as it would be one for my collection i would never sell and reserve for a very special heli (probably for banshee). I will ask my contact from scorpion if they can help if you are ok with this?

Dont worry about other side of the world, this is why we have fedex!

This motor im sure i can appreciate the difference it can offer

[powercroco]

no problem on my side, if you want to do it.
you know, I really love crazy projects.

may be you get them to send out a housing to complete it with stator and winding.
better option could be, I build the stator and I use a statorholderpart out of my storage and send it to them, they complete it with a 14P PAW-edition can and send it to you.
this way would reduce the number of needed sendings pocesses.

I think, to wind the motor, will be the easiest step.

[helicraze]

Hahaha i understand. Perhaps we talk via email? Let me know how to be in touch please.

[powercroco]

a very special "PAW-edition".
Winded with1,8mm wire (4+4YY) on 0,1mm silicon-iron platet stator, using 0,25mm thick and rigid insulation papers to prevent damages by the hard and brittle statorplates:

[helicraze]

Anyone else flying the paw motor?? I wonder who got the winders special edition?? Hehe

[powercroco]

I'am also interested in knowing this.
I think, these are "normal" helicopter pilots who never would open a motor to have a look inside within the warranty time .

[powercroco]

to remain the complete bearing seat I changed the torque holding pin to the bottom of statorpackage.
it's a bit more difficult, but I think it's worth the effort.

also the sharp edges of statorholderpart are files down.

the bearing inside the holder is an old one - I use it, to prevent bending the thin walls of bearing seat during the mounting process.

[helicraze]

Lovely work. Im suprised you worked so quickly i expected 2 weeks!!

[powercroco]

you are right in this - noone knows, what still could happen.
but now the chance is really big, to old the set time limit.

and many thanks for supporting both scorpions and also my actual charity!!!
