And we thought the fun cub tires were big, I put 6in Dubro air tires on my old trainer converted it to electric and a tail dragger. Took both of them out the desert this weekend for some dirt bike riding and off roading. Put my GoPro on the FC and chased around the dirt bikes and trucks and go some good footage I will get up soon. Gonna look into a smaller set of the Dubros for the FC see how they work.

The Dubros are just too heavy for the Cub. We went with the
Dave Brown:

1.8oz compared to 6.5oz each. We had to shove the biggest
battery we could get in it all the was to the back to get it
balanced.

They look real good! And they are about half the price.

But even then, it's only going to corrode at the point of contact (e.g. the edge of a hole with a steel fastener through it).

If aluminum had a problem with saltwater, you wouldn't find so much of it on ocean-going boats!
I used to sell A/C units in South Florida. I had a nuclear engineer explain that the Trane units were made of an alloy used to transport really nasty stuff. Raw aluminum as used in spotlights does not do well exposed to salt water. Most boat aluminum is an alloy and most is anodized. The A/C units did fail as they were aluminum touching copper. Cheap units of raw aluminum failed when the fins dissolved.

BTW the Space Coast is judged to be the most corrosive area on the eastern seaboard. NASA found that out after building KSC here. Wierd things go on beachside.

Kimber is that the articulated gear made by the Luddite guys, the cub gear guy, I think? If so how do you like them and was the mounting a big problem? The non-internet or PPal guys? Dave/zeezee Nice FC

It is by cublandinggear.com. The wheels are the same size
as the originals.

If you get the Dave Brown, make sure they are the treaded one, the others are flat, square
cornered. Got a set of those by mistake.

I can FINALLY post on this thread as I am now the proud owner of a FUN CUB! Terry over at Small Parts CNC has been very helpful and got me the right alumnium mount for my motor (all mounting screws 19mm apart)

I'm using a Thunderbird 36 esc and got a deal on Spektrum 4000 & 3010 micro servos from my LHS. I'm also going to use a Sullivan tail wheel.

I'm using medium CA on everything and the build is going fine. The only "issue" so far is the Elevator and Rudder push rods. They just need to be half an inch longer or I may turn my servos around.

I can't wait to finish!

Ricky

So I got myself another Fun Cub. It came with the aluminum mount out of the box with a 25 mm mounting pattern. My motor of choice used to be the Turnigy 3536/8 1000kV which has a 25mm/19mm pattern that I had to reverse for FC mounting.

Does anybody know of a 3536 with
- 1000 - 1050 kV
- 5mm shaft
- 25mm/25mm pattern
- Is already setup for installation behind the mount (I mean I do not have to reverse the shaft)?

I checked Headsup, HK and Hobbypartz but did not find anything that fits my requirements.

P.s. Yes, I know, I could just reverse the shaft on another Turnigy and get the smallpartscnc mount again, etc. pp. but I figured I'll ask the FC maniacs here for input.

How about this one available as either 920 or 1100kV...

Also branded as E-Max instead of E-Power. If you search for BL2815 you will find them from various suppliers.

If you want to you can flip the servo in the same hole and bend the wire. Kimber has that posted a couple pages back. Carve a new hole works too. If you want to spend a little extra that worke too.
