Anyone have any idea how high the Estes Vaper will go on a C5-3 with the engine adapter? Im fixen to order the Vaper later this week.

I have been flying one for a while. I have tried C11-3s, with POOR results. Both flights the parachute either didn't deploy or tangled up and the rocket suffered a tail-first crash into the ground, requiring an engine mount replacement, etc.
But to answer your question, the Rocksim results are: Altitude 323 feet, optimal delay 3.23 seconds (should be okay), max speed 82mph.
Good luck, and let us know how it went.

Thanks.. I would have thought a C11-3 would of been stronger but I guess not.. what was ur altitude on the C11?

Oh ok.. thanks, reckon I'll fly her on a D ..don't wanna bust her up on ground for sure
I've had many good flights on an D12-5. I just built a second one because the first Vapor has a lot of tube spiral creasing going on - I expect I'll have to retire it fairly soon. I put in an long stuffer tube in the second one to reduce the internal volume enough to make parachute ejection more reliable. A little less altitude, but I can live with it.
Also, I normally use an 15" nylon parachute instead of the provided 18" plastic one; it doesn't drift as far. I even tried an 12" nylon parachute once, but that was with tall grass fields in all directions, so it didn't hit the harder ground.

I've had good luck flying mine on a C11-3 when I have a small area or don't feel like chasing it. I've recorded 293 ft. Mine weights 5.01oz without motor.
D12-5 and E12-6 have been my motors of choice. I've used an 18" x-form parachute and that has worked well.
Using my rocket as an example for the SIM. Looks like we pick up about 170 ft on a D12 by shorting the body tube length. That number jumps to 218ft for an E12
Nice! It's big enough for me and looks better as a Shorty IMO. I'll use the second tube for a scratch build and use a D instead of an E. I've tried to do the Simulator and it always gets soo far before it freezes on me. I'll try again at some point.
If you’re talking about OpenRocket, it should *never* freeze. Help is available over on the electronics and software forum.
