Do your air cooling and let other do the FF and Hubsinks! Don't be a bully.
I'll say what want here as I'm not offending anyone and keeping it on topic, I'm putting a lot of my time into cooling hub motors and think I can discuss these issues here with people. Show me one instance where I'm bullying anyone. Mabe you can argue I'm bullying FF + heat sinks, but who the heck cares if I am bulling that?
I feel like questioning FF and hubsinks is the same as questioning if the world was the center of our solar system hundreds of years ago, I've even thought of this for weeks and your post just confirms it. Why are some of you guys so defensive about your FF + hubsinks? I'm just simply trying to find the best cooling method. Why do some of you care so much and get so defensive? I've noticed this defensiveness for a while here about the FF, like it is a protected religious thing. I'm just kind of sick of it now, this is a forum about research and progress, I can question the FF + hubsinks and shouldn't be treated like I'm attacking someones religion.
You mention Hard work? I don't even want to mention how many hours I put into my setup, I'm not complaining. This is mostly a hobby after all.
I can see sketchism not liking it because he is selling the hubsinks, but he is actually being fair about the discussion considering he has personal stake in the business. Although he doesn't do a simple test of showing me the external magnet ring temperature while the bike is in motion. I still wonder why he can't do a simple test, or is it possible the magnet ring is cooling sufficiently fast as long as you are cruising along with your bike without sinks, like I have found.
That post above you commented on was in direct response to someone who was asking about sinks without FF, and after others told him sinks with FF is not worth it, just go back a page and read for yourself. I agree it is somewhat confusing if read out of context, but certainly not worth making a post about it telling me to stop bullying people about FF, especially after I responded back
to the post to stop any confusion and not seem like I'm attacking your guys precious hub sinks and ferro fluid.
I'm also not bullying anyone, I'm even telling people to specifically check their exterior magnet ring temperature by touching it at various times to see just how hot things are getting and that will tell them how well sinks will work. This way they can see for themselves and not just take my word for it.
I've asked people to check their temps for me after finding that my magnet ring was not getting hot if I was at a speed over 15MPH while riding, even when I had an internal fan turned on at super high speed and the winding temp held at 115C, the magnet ring was just cool to the touch while riding. It took me just a short 20 seconds of riding for my magnet ring temperature to fall from a burning hot 75C (got hot only after bike sitting for a long time) to a just slightly warm temperature while moving.
My own tests showed that the motor will cool itself rapidly without sinks while the bike is in motion. However, I've said that if the bike is stopped this isn't the case, the motor will get very hot. But my motor won't even get hot while stopped unless I ran an internal fan while stopped, as I DON'T have FF.
Not one person has done this simple test for me to simply check how hot their exterior motor temperature is getting. Not even Skethism who makes the hub sinks and has certainly read my posts about my findings where I questioned this specific issue. This issue was very important because it showed me there was a bottleneck in the heat transfer and hubsinks and FF will only do so much.
Why can't he simply ride his bike at above 15MPH or higher, and simply just stop the bike and touch his magnet ring to see how hot it is getting?
I've always said FF will work, I've never said it wouldn't and have said mostly everyone is better off using FF over air cooling. I've modified my motor for air cooling and used it for 2 summers on a cromotor and it works. It eliminates overheating on my hard runs. I'm just questioning how well FF + sinks work, because it is a lot easier to use them compared to my air cooling setup.
I want to find out if FF + hubsinks will do the same, because I don't want to put oil in my motor and then find out it doesn't work as well. I need to use silicone in my motor and have lots of outside air running through it so the last thing I want is an oily mess inside.
I would gladly switch over to FF + hubsinks if it will work, or even work somewhat close to my more complex cooling setup. Just shows that I'm not attacking it in any way, just comparing with the intent to switch over because it is far easier to use.
It is also this post which concerns me, someone who used oil and sinks and an MXUS motor is complaining that he still overheats and is looking for something better. It concerns me because I never have to stop to let my motor cool off with my setup.

I know in the end I'm going to have to convert my motor over to FF to finally find my answers But I'm going to wait a summer so I know the limits of my current cooling setup to better compare the two. When I finally do convert over this should finally settle the question as to what works better.
If the FF works better or just as good, I'll say that my cooling setup sucks and not worth it.
Some of you guys have to stop acting like FF + hubsinks is a religion and maybe there could be better alternatives. Maybe you guys haven't found the holy grail and there are better alternatives out there. Remember in the end its just some oil and aluminum you are getting so worked up about.
Like I have said in one of my early posts, I'm specifically trying my air cooling setup to try and promote research into the area. I want progress made in this area, not just take it to heart that FF + hubsinks is the best and you can't even question other cooling methods because you may INSULT some peoples hard work.
I'll say this again, read over anything I have said in the past, it is all about questioning the effectiveness of cooling, not attacking anyone personally. Remember, it is guys like me who question things and find alternatives that make progress throughout history. It is guys like you who stifle it with having a closed mind.
