Converting your Turnigy Motor to a Pusher Mount

[stewjw]

It sounds like you have been palgued with this question. If I understand correctly, this mod is only necessary if you are not mounting the motor on the prop end.

[stewjw]

Is this mod necessary when mounted as a pusher motor? I know there are motors with reversed timings for slight improvements in performance but what's gained by adding a collet? Do this motor shafts move when used in this configuration?

[ehsanaman222]

At 2:00 when you put the set screw back in, didn't you have to file another flat spot since the shaft had now been moved?

[silverfd]

where do you get the collars from? why do you need them?

[rcFoamFighters]

@silverfd you can find them usually at your local or online hobby shop. Look for Wheel or Axel collars. If you can't find them there you can search on Amazon I have gotten them there before. The reason you need the collar is because the retaining E-Clip dos not have a slot to go in the new shaft position. The collar replaces the eclip and makse sure the motor bell and shaft wont come flying off!

[ourblue]

Just a word of warning. When you fix the motor mount to the motor make sure that there is enough clearance for the grub screw so that it doent foul on the motor mount and burn out the motor as this would stop rotation. If you remove the shaft completely and reverse the shaft you can use the flattened side of the shaft to fix the grub screw. No messy filing.

[grpfff]

how do you remove the E-clip or something?

I tried it but i'm rather braking the clip than removing it

[pencon61]

OK I did the operation but the 2 little washers went flyiing under the work bench of course (where else) but the 5mm collar I put on has a little slant on each side and after the flat grind theres absolutely no play . Does the motor absolutely HAVE to have those tiny washers or am I ok ? ps. you should warn about the washers in your video .

[ama409573]

Instead of pounding on the end of the shaft to push it through I came up with a more delicate solution. If you have any size drill press in your shop it makes a great arbor press for pressing the motor shaft to the correct length in the motor can. I had a lot more control adjusting the length and no chance of bending the case. Thanks for the how-to Paul!

[Loye911]

hey, great stuff your doing again. i used you technique to build. its the 1st time i could get em flying..so mucho thanx. i do have a question about a step in this vid. once u balance the motor on something, did u just pull out the insides???? can u do that?? i missed it. how? also u start tapping only after the inside is removed?? i cant believe no one asked u that. thanx again.

[rcFoamFighters]

@Loye911 Once you remove the E-clip, you can slide the can with the shaft out of the motor. The e-clip is all thet holds the 'Insides" in. After teh clip is removed it should easily slide out. The Shaft will be in the can side of the motor.

[Loye911]

@rcFoamFighters Got it! thanx. i did learn that you need to be careful pulling it out since ther are 2 small washers on the end that automatically get forced out when u pull the can apart. do u have any suggestion on how to file the shaft down. i have a filer, but i tried it and it seems like it would take prison time to ware away the metal of the shaft. is there a better tool, or is there a place i can pay to do it? thanx again

[PARTYjohn69]

Paul, first up great video! I am curious as to how tight the shaft is on the can after you've moved it even with the grub/set screw done up tight? My concern is that if it's a tight press fit from the factory, once you've moved it(reversed the shaft)the only thing holding it on is the single little grub/set screw and I'd be a little worried how long this would hold for??? John

[altops]

hey what happened to the Jupiter plane? I thought you said you were gunna do weight lift testing with it?

[rcFoamFighters]

@altops

Its still in the plans to do more testing with the Jupiter, just been a bit busy lately and haven't had time to repair it. Once i fix it, we will get back to the tests.

Thanks!

[flyby8906]

Nice vid Paul very well done.

[rcFoamFighters]

@flyby8906

Thanks Gregg! Hmmm, weird I replied to you already once, but it doesn't show here. So I added it again. Anyway, good work on your polaris video. Can't wait to see more of your other planes too. Thanks Gregg!

[daryl75052]

im confused, whats the benefit if this over switching 2 of the three wires to make the motor run in reverse and using a pusher prop?

[rcFoamFighters]

Daryl as I have mentioned in the comments below, just changing rotation is correct if you have a model that will allow the motor to be mounted with the x-brace on the same side as the prop. Such as planes with L-shape motor mounts. A lot of planes do not have those type of mounts. So this video shows how to modify the motor to put the x-mount on opposite side of the motor from the prop. I guess I should have noted that better in the video as i am getting a lot of comments about this. Thanks!

[daveyedgar]

good vid, curious though, can't you just mount the motor facing the opposite direction and reverse the wires when connecting to the esc?

[rcFoamFighters]

@daveyedgar

daveyedgar you are totally correct if you have a model that will allow the motor to be mounted with the x-brace on the same side as the prop. Such as planes with L-shape motor mounts. a lot of planes do not have those type of mounts, so this video shows how to modify the motor to put the x-mount on opposite side of the prop/shaft side. i guess i should have noted that better in the video. Thanks!

[insAneTunA]

I enjoy watching the tutorials very much. 5*

Great info Frank :-))

[rcFoamFighters]

@insAneTunA

Thanks IT!

[Lincolnjt41]

Nice video I bought this motor and put it in my f22 but unfortunately killed my 4's so will go bigger another day. We had to make a box so we could use the motor so this video is perfect thanks for showing us.

[rcFoamFighters]

@Lincolnjt41

Thanks for the comment Lincolnjt41! Sorry to hear about your battery. I'm sure yu'll have that crazy motor into something soon though. Keep up the great flying! Oh, Love your new Yak video too. looks like a cool plane.

[wildhover]

now that's what i call rc education!

[rcFoamFighters]

@wildhover

Thanks Ken! The video was a bit short, but hope it was clear enough. How's the weather in Cali? Sure it's better than hear, supposed to be raining all weekend, : ( bummer.

[wildhover]

@rcFoamFighters it was clear enough for me. i liked the fact that i could pause it and read the captions. don't know what the weather is like at home since i'm overseas right now doing some family bonding/quality time. i was using a hammer but will look around for a 30lb item the next time (my way ended up with bent motor shafts). this video is a keeper for me.

[rcFoamFighters]

@wildhover

Thanks Ken! Yeah the 30lb weight may sound stupid or hoaky, but it seems to work much better than a hammer. With just light taps the weight has enough force to push the shaft straight . A hobby vice would most likely work too, but i don't have one at the moment, LOL. Cool on the vacation, Sure it's good after all the work and school you have done. Did you go to the Philippines? I haven't been since I was a kid. My Mom's family is from Baguio.

[wildhover]

@rcFoamFighters yup, i'm here in the Philippines. my wife is from Quezon City and my family is from Bacolod. I have been to Baguio but that was like 10 years ago. i had an idea of using some of your FoamFighter leverage to persuade turnigy to build some of your personal favorite motors in their standard form (which is more suitable for heli's) and also the converted form you describe here (which is more suitable for park jets). i wouldn't mind paying even a few bucks more to save me the trouble

[JC0926]

Just finished mine... Worked perfect, and was not hard at all. Just make sure that you tape the housing before grinding the flat spot on the shaft, if you dont do this you will have debris on your magnets. Thank you Paul!!!

Jonny

[rcFoamFighters]

@JC0926

Awesome Jonny! Glad it was easy and worked for you! Hope your FF-117 flies great, good luck for the maiden flight!

Paul

[jacquesone100]

Snug!

[rcFoamFighters]

@jacquesone100 Thanks Bro!

[sNstRflyEr]

Please, what is the difference? What does pusher mean? Thankyou. J

[rcFoamFighters]

@sNstRflyEr

Sorry if I was confusing, probably not teh best terminology. All I mean is changing the motor mout from the front to the back so you can mount it in a pusher jet format. Hope that helps.

[sNstRflyEr]

@rcFoamFighters Thankyou, i probally should have been able to figure that out. Great video. J

[gripchion]

Thanks for sharing. I always wondered how to do this but I didn't want to ruin a motor trying. This is the kind of knowledge sharing that makes everybody better modellers. Great job!

FFFTW!!!!!!!!!!!!!!!!!!!!!!!!!­!

[LTF85199]

All you have to do is reverse the wiring right?

[rcFoamFighters]

@LTF85199

You are correct for reversing the rotation of the motor. This video is more to show people how to reverse what side the x-mount is relative to the side the prop mounts too on the motor. For some plane designs you need to change how the motor mounts. These motors originally have the mount on the same side as the prop. Doing this procedure moves them to opposite sides. Thanks!

[LTF85199]

@rcFoamFighters Sorry you are right, I Jumped to soon to conclusion..

[rcFoamFighters]

@LTF85199

No worries LFT85199. My Bad for not explaining it more clearly. Thanks for watching and participating with comments.

[BRANDORC]

to change the rotation direction the motor is spinning yes, just switch any 2 of the 3 wires going to the esc. but what paul is doing here is actually changing which side the motor/prop shaft is sticking out of. the motor mount can only go on one side, and from the factory, the shaft and mount are usually on the same side, making it difficult to mount the motor to the plane. by having the shaft come out on one side, and the mount on the opposite, the motor doesnt have to sit "inside" the plane.

[LTF85199]

@BRANDORC Sorry you are right, I Jumped to soon to conclusion..

[johndog35]

I have done this before but not with oil.

Will have to try the oil next time to see if it makes it any easier. Thank for the tip.

[rcFoamFighters]

@johndog35

Thanks johndog35! The oil i think helps a little, but teh heavy driver is probably more the key. Please see my reply to startazz below for more detail.

[startazz]

Thats funny i was trying this about a month ago but couldn't get the shaft through the other end ;-( i bet i can now so thanks for sharing this Paul/Frank = 5*

[rcFoamFighters]

@startazz

Thanks startazz! I think the drop of oil helps, but the key to driving the shaft though is to use something heavy for the driver like the barbell. Using something like that makes it easier to press the shaft forward with a lot of force accurately. To get the same force with a hammer, you have to swing hard and may not swing accurately. With the barbel weight, its heavy and you just lightly tap it into place. The force transfers easy and straight so you don't bend the shaft.

[rcmotorsect]

thanks!! i was wondering how to do this, this is going to be verry helpful when i mount my 1600 watt motor to my sw-1 THANK YOU!!

Ben

[rcFoamFighters]

@rcmotorsect

Cool rcmotorsect! i have been watching your videos of the plane you are making. Should be a crazy fast one. best of luck with it! I can't wait to see it done and flying! I hope your maiden flight is awesome!

[exiledconnections]

thats a great thing to know guys good video

[rcFoamFighters]

@exiledconnections

Thanks exiledconnections! Hope this helps a little for anyone wanting to try the procedure. Sorry if the video is a little crappy in quality, I was in a rush to make it for a viewer who had the question about it..

[norsktysker]

Very interesting.

Just one question:

Can't you just buy pusher-props? Or are they hard to get/ do not exist?

Or is there another difference now, apart from the motor spinning in the other direction?

[rcFoamFighters]

@norsktysker

You can use normal or pusher props. The reason for this is more to change how the motor mounts. This changes what side the x-mount is relative to the prop side. Some plane designs won't work with the x-mount in the stock position, which is on the same side as the prop. So we slide the shaft through so the prop is now on the opposite side. Thanks!

[RCTESTPILOT1]

Thanks for the vid, Why do you have to leave a bit sticking out the other end? And do you know why motors arnt already like this?

[rcFoamFighters]

@RCTESTPILOT1

Thanks for watching RCTESTPILOT1. You usually need the extra bit sticking out to mount the shaft collar. This is because there is no groove for the retaining clip. if you don't add the collar, the motor can could slide total off. If i could be more accurate in grinding i could regrind a slot for the clip, but dont have a machine to do it, LOL. So the Shaft collar is the nest best thing. Thanks for the comment.

[Skydive4ever]

Woah, what a coincidence, I JUST finished doing this for the first time on one of my motors :-O

[rcFoamFighters]

@Skydive4ever

Cool Skydive4ever, thanks for watching!

[TheLipRipp3r]

1st comment!

[ElRhinoProductions]

@TheLipRipp3r you lot still think people really care about "first comment", if your going to comment do it about the video or at least say what you think about how it looks

[TheLipRipp3r]

@ElRhinoProductions

ha ha.......try to have more fun, tough guy! I was thinking of subscribing to your channel so I could post "1st comments" on your new videos just for laughs, but it seems you only post flight-sim videos so that would just be......boring!
