Title: Oil for bearings in Cobra Motors
Post by: Matt Piatkowski on October 02, 2015, 08:04:34 AM
Hello,
I know that Cobra Motors sells "specially formulated" oil for the ball bearings in their motors.
I live in Toronto, Canada and The Canada Border Services Agency always finds new and clever ways to grab some of my money while I am "importing foreign goods".

I never know for sure if and how much they will extort and a little bottle purchased from Cobra Motors for $5.99 USD may cost me in the end $30 USD.

I wonder if the Air Tools Oil available in Toronto for $7CAD for 8 fl.oz will work well as Cobra ball bearings lubricant?

Thanks,
Matt

Matt, I use regular 3 in 1 oil and have had no problems. I have heard that others have used sewing machine oil. I'm not sure whether air tool oil would work or not.

Don't hold me responsible if your Cobra bearings don't last on 3 in 1oil.  ;D

Wow $30!  I'd start a movement to change things.  $30 for a $6 bottle of oil. Unbelievable!

The main problem is always so called brokerage fee and sometimes a mysterious item called "handling fee".
I am not even mentioning taxes that go of course on top of all these fees.

Example: I have purchased 10 LiPo envelopes (safe charging bags) using one of the US based warehouses. The price I paid was $26 USD but, when the bags arrived, I had to pay $38 CAD in Canadian fees and taxes.

These bags were manufactured in China so NAFTA import exclusion rules did not apply but you never know these days.

Canada Border Agency can qualify the product any way they want when, what is quite common these days, the product label says nothing about the country of origin and arguing with them is very time consuming and difficult.

Just get some 90w synthetic gear oil from a cycle shop or pack them with high temp grease. I think using light weight mineral oil you would have to service them too often.

I'm guessing you'd want to stick to the same viscosity as what the factory stuff is. I will guess that if you used grease vs oil, you'd lose some rpm through a bit more drag.
I'm not 100% certain of this, but it's something if be concerned with.

Matt,
The key to having things shipped to Canada is to never have it shipped by either UPS or Fed Ex.  If the place you order from won't ship by US Postal Service then don't order from them.  Not sure how far you are from the border, but if it isn't too far, have the items shipped to a parcel drop on the US side. Then hand carry it across and declare the amount.  I came through the border the other day with over $300 worth of batteries and was not charged anything.

Hi Alan,
I know the drill to avoid extra payments and the NAFTA rules and the custom exemptions as I stayed about 10 years in Bellingham, traveling across the border hundreds of times.

I have found the "Trinity" ball bearings oil in Toronto R/C stores and the Cobra Motors confirmed that this oil can be safely used so the issue is closed.

I have met recently Gustavo who flies nice Legacy with the Plettenberg motor and he had one of your 3 blade props.

Do you still make them?

Regards,
Matt
