Default carbon landing gear crack

Hello Some weeks ago I had a bad landing and had to rebuild the lower fuelage on my 30cc plane. I used plywood and I noticed the carbon landing gear had a crack on the lower part only a slight delamination on upper part but the gear seems sturdy and strong. I contacted the maker of the gear and told me to pour some thin ca on the crack. I did, and it has been holding nice for 5 flights as of now, no further delamination etc. Should I keep it or replace it?



This is the underside the other side is only a few mm and barely noticeable.

I would scuff an inch on either side of the crack and apply a couple fiberglass patches with thin CA as well. As long as it holds up I would keep using it.

I would be inclined to replace the gear.

It is holding without further delamination, I used CA on it and is working just fine. However, I will put a patch of ca soaked carbon fiber cloth over it. I am not spending more money on this trainer unless it cracks again.

If you do it properly it probably wont.

I have repaired it with a patch of carbon fiber fabric and CA. I think it is fine.

Regards.

If it cracks again replace it with Du-Bro's Super Strength Landing Gear . It is ment for 35 to 60 size planes . It weighs 4 3/4 ozs . It absorbs the shock of a rough landing . I dosen't bend like wire or aluminum . You can paint it . I have been using it for a few years now and I have never had one fail ,never had one break or bend or anything . I really like them .

Had the same problem on my 50 cc Edge. Fixed it by holding the Wet/Dry Vac at the back of the crack and applied CA to the front and let the vac suck in the CA. It worked for 3 landings and then failed costing me a rather expensive propeller. No more Carbon Fiber gear for me. I would replace it ASAP!!!

I like using the Dubro super strength LG as BikerBC stated, I wish they would make them in some larger sizes though, they are 13" wide by 4" tall or 14 and 1/2" by 4 and 1/2" depending on where you check the specs? Never had trouble with them.
