I really like the new Reds R5T motor looks to be quality being Mario is involved they are good tuned mills man I Remember when the GRP was the motor to have when Drake was running those mills had a great run for sure very good performer. I also like the new Vox mills the head is a gravator its different from the norm being they are picco based they will last well all my previous picco mill last super long.

Of all the engines you mention, the Bullitt is going to be the best one. Not only is it an OS, it's the OS Speed. Same exact motor as the XZ-B Speed and both bearings are ceramic.

Bullitt B-218
RPM 40000, 3 Ports, 355 grams, HP 2.6

Vox OTTO C.1 Cross Pro
RPM 32000, 5 Ports, 355 grams, HP 2.5

Reds Racing R5TE
RPM - Not found, 5 +1 Outlet +2 Boosters Ports, 348 grams, HP Not Found

All the other specs (bore, stroke, capacity, fuel) being equal.

I need to go read up more on the impact of inlet, outlet, and booster ports in Nitro engines. But based on the above it looks to me like Reds, Bullitt and then VOX. Hard to tell if 2 additional ports in VOX can overcome a 8K RPM difference the Bullitt introduces.

So the Bullitt is coming on strong but....

You can not really go by specs of power and Rpm listed by the manufacturer. All motors listed are great engines. I sell Bullitt engines and it is the same engine as the Os Xz speed, current National champ in the Usa. I am currently modding a Reds R5 and it really looks like a great engine. I also sell the Picco boost wich is similar to the Reds but not the same.
If I was putting an engine in a Revo I would just go with a cheaper .23-.28 the engines you are looking at are more specific to 1/8 racing and not lugging around a Revo for bashing.

Rpm ratings are not always max rpm, but rpm at max power output.
