Would anyone consider it necessary to reinforce the elevator on their SW? I'm getting closer to completing this plane (I build pretty slow )

just started building my V5 version.
The elevator has a carbonstrip in it ready to be glued in, if that is of help

I've started with the wings, going to add the flaps.

The elevator does? My horizontal stab does, right before the hinge line. And I added another CF strip further up. But does the actual elevator need reinforcement?

Oh, and second question. Would it be considered safe to just Gorilla Glue my H-Stab to the V-stab? I don't think there's a problem wiht it, but would anyone else object?

Definitely put a ribbon of carbon in your ACTUAL elevator. TEST: Hold the control surface and push to the extreme end of the control surface. End result? lots of flex. Reinforce.

I don't think it is necessary to glue the horizontal/vertical stabilizers together, but not a bad idea either. I don't see any benefit other than transporting the planke to have it removable.

I covered mine with packing tape, not sure if it needed it or not.

I just have a strip of CF in the stab. Nothing in the elevator. No issues here.

My elevator flexed quite a bit until I removed the EPO hinge and used tape. No issues after that, and I have a porky plane. ~Wingnut13

I managed to do a 1.7k FPV flight this morning. Limited by my Futaba FASST radio, waiting for my Dragonlink LRS to arrive.

There is absolutely no need to reinforce the elevator ! you are not flying a 3D plane, it's a fpv platform with 5mm of elevator throw!

I recover easily from high speed dives with no problems on the stock elevator

remember that to some extent, you want your plane to flex if you stiffen your plane too much, it becomes like riding your car without a suspension.

high speed dives? power off, reduce airspeed, then lower the nose and you won't get into a high speed dive. Also deploying flaps and you can descend at a steeper angle and not get into a high speed dive.

High speed dive = either pilot error or aerobatics.

Just so everyone is on the same page.

The elevator is the control surface that moves up and down.
The horozontal stabilizer aka horizontal stab is the fixed wing that the elevator is attached to.

The horizontal stab, as you all know, has a rod in it but it can still benefit from a carbon strip. The elevator is fine as is and needs nothing.

You forgot also, (or wing snaps off) like mine....

LoL I don't think the high speed dive caused that, it was probably the "abrupt" controls (ie. too much elevator) for that airspeed resulting into too much load on the wings.

Did you have the whole bottom of your wing fibre taped? I just can't see how with 4 carbon tubes and the bottom fibre taped a wing could snap.

You are probably right I did not have fibre tape on it, but alredy got some and will use in mine next SW, but be carefull this baby gets speed very easy because of the load on it.
