A couple years ago i had also tried a 19x13 woodie hybrid with wider blades and the engine met its match there, bogging down to around 6500 and running hotter than normal. Too much load and definitely more than my 21x10 hybrid. Wasn't happy and you can tell. My 21x10 is a true narrow blade design.

I think Ken is right. When I installed the new set of clips I probably didn't seat them properly. I don't buy what Hobby Services said about the bearings being bad with shrapnel in them.
Yeah , it was just a thought Matt.

I doubt the circlip theory. Even though I do insert these circlips the way Ken said, they wouldn't just come out if put in the other way 'round. Even with excessive force, the circlip wouldn't come out without there being visible damage to the circlip groove, unless it wasn't inserted into the groove properly, or the groove isn't deep enough which would be unlikely.
After I insert circlips, I always squeeze together slightly and turn it. If it's seated properly, it will turn easily. if not, then it won't turn.

Still a very strange failure though.

Delta has been in the shop lately for a face lift so no recent flying.

Ron had a lot of issues with his 33's, enough so to move to the much less expensive EME line. The DA 35 also had some issues according to Ron.

if you don't have a plane for your engine yet, consider buying my nib Shinden
.
Message me with your asking price.

Thanks, Gary

This should link you to the copper rtv gasket maker
https://www.mcmaster.com/#catalog/122/3463/=15r71j0

u want the permatex 81878, can also pick this up in most auto parts stores.

This should be the material used. I used the 1".
https://www.mcmaster.com/#catalog/122/851/=15r724i

This is the teflon tape used to wrap your mold. I used a 1/2" alum wing tube. Also wrap around the outside to hold shape while setting up.
https://www.mcmaster.com/#catalog/122/3488/=15r72bu

Pair of gloves and wax paper for the table is advisable as it is pretty sloppy while doing. I'd recommend two wraps if using the 1" material. A single wrap blew out on me, but they work great.

I guess I'm not following. I thought it was a fabric like material that was wrapped several layers, each one getting a pasted with rtv gasket maker.

rm it tubing is used what do you mean by two wraps? One tube install another?

Thanks guys for helping explain this.

Don't use it as a tube. Use shears and cut it to the length u want, then cut it again to open it up as one flat piece which u will work the paste into and then wrap.

This looks like a dead thread, especially considering the original post. What's next? How about a 4-stoke, regular gas engine???

Matt was a good friend and a very talented modeler. We all miss him quite a lot.

Yes Ed, my buddy Sergio Zamora knew him personally and I talked to him a few times over the phone and bought some top quality stuff from him. Matt Kebabjian is missed in the R/C community. He was a true artesian type modeler. RCU please keep this thread open as an honor to his legacy and contribution to the community.
