No, they don't. EF planes do.

Maybe something that could be improved.

yes, and 'in theory' drip thin ca into hole to harden the wood... i remember someone did blindnutting for sfg but that involved recovering so no no for me... p.s. that motrofly... does it bolt right on? or do i need spacers? and was spacers supposed to come with kit? cause with 1.5 buck huck there is spacers, but here there was no spacers... just asking.... so far just cut holes, hinged rudder, finished tail section, assembled landing gear... now all i have to do is wait for servos and next month for motor and esc....

there's holes in the balsa tip that guide the screw into the backed plywood. you screw it in, remove it, add some thin CA, let it cure, and there you have a pretty tough and secure mount without requiring more hardware than needed and screws that you don't need to loctite or anything else in fear of them backing out during flight. the 70" planes and up have blind nuts and bolts, not necessary for this size airframe.

Yeah, I guess. A friend installed blind nuts but required re-covering.

Thin CA into wood will work, but blind nuts will help last longer, after many cycles of installing and removing.

Spacers didn't come with mine. The a40 requires 10-12mm of spacing (7/16" roughly). I don't know about spacing on a motorfly.

Weird, I know, but I have to remove my SFG's every time I pack my SC into my car. A couple of times a week...the screws probably hold fine over time, but I prefer thumb screws, so I made a cap for each wingtip, and put a 6/32" blind nuts in each wing. Very easy to remove or put on with no tools. Wasn't that hard, either.

Got the idea from Stickybeatz. His turned out awesome.

Here are a couple of pics to help see what I did and how it came out. I used 1/8" balsa for the end cap, then I cut out the original section of the wingtip which held the plywood ring. I bored out the ring to fit a 6/32" blind nut, then pressed it into place and used thick CA to hold it on. I glued that to the back of the wing end cap after carefully placing the hold in the wing caps.

Then I used med CA to glue the entire wing cap to the existing wingtip. I use 6/32"x3/4" nylon thumb screws to hold the SFG's in place- works like a champ!
