Just curious as to how easily your wheels rotate. Mine do have some friction, not a lot but noticeable. Should I be adjusting them somehow?

Do they have bushings or bearings? mine has bearings and they are really free

Lube them.

I have Dubro low bounce wheels on the mains on my Nano Boomerang. The wheels rotate freely, but the tyres are soft, and wheel drag on the ground has a useful slight braking effect. I like this setup as I don't have wheel brakes and the ground handling is just fine, with taxy thrust being easy to find, whilst the plane rolls to a stop nicely on landing despite residual engine thrust. For a very short time I replaced the Dubros with some "jet wheels", again unbraked, and these were so free rolling that the jet didn't want to stop, so I replaced the tatty old Dubros and restored the ground handling.

If you use brakes - I don't know if brakes are mandatory in Canada but they're not over here - then lubing the wheels will be OK, but without brakes I wouldn't bother

I'll try some 3in1 oil, unless there are other suggestions?

I would use something heavier than 3-in-1 oil - like high-temperature grease. Jets have higher takeoff and landing speeds and thus have more of a tendency to either spin off the lube or burn it off. Its important to inspect and lube bushed wheels on a jet - if you don't, you run the very real chance of the bearing galling on the shaft and locking up. I have seen that several times before and depending on when it happens, the result can be unpleasant.

Many jet wheels use oilite bushings to help alleviate this problem...

Sounds good. I'll see what I can find. Any brand names you can suggest?

"White lithium grease". Available at any auto parts house, a small tube lasts years.

Mine are BVM and they sure aren't free!

I've been using automotive silicone grease to lube my axles andbrake o-rings for years. It works great and is available at any auto parts store.
