Fastest .60 engine
 

I'm looking for the lightest, most powerful .60 sized engine. I would
prefer something that would run well with a tuned pipe. The application
is a bit unusual, this is to go into the tail of a Dornier Do 335. You can
see the project on http://www.wingsontheweb.com/do335/ if you're
curious. I want to run a tuned pipe into the rear fuselage. Weight is
a factor, the tail needs to be kept as light as possible.

Jett Engineering has one of the best power-to-weight ratios

Check out their BSE .65L R/C with muffler (AAC), 15,000 rpm with an APC 11x6 prop, Total weight including muffler, 16.8 oz.
$325.00

I was gonna say Rossi-60 until I saw the "weight factor"- I think the YS-60 is a runner but heavy also-

Jett is the obvious choice-

I think if you look at most other 60 size motors, the Jett 90 is as light or lighter than most 60 size and a heck of a lot more powerful.
It's the combo that I use on my Great Planes F-15. Quite impressive!!

It is hard to beat the YS 60. It is a screamer!!! The nice thing about them is that you have the benifit of the pump too. It will swing 11x7 - 11x7.75 or 11x8 in the 15K no problem on the ground... when piped properly.

Jett .50

All you need to know.....

Dave...

Did you look at the plane?

RE: Fastest .60 engine
 

No engine will survive in the back of that thing ! And I certainly wouldn't be
putting a Jett back there....[X(]

BTW....the Tower .75 is the fastest .60 engine....[sm=thumbup.gif]

FBD. :D

Yep, I didn't see the pics.

Scratch that recomendation.

RE: Fastest .60 engine
 

I would suggest the Jett BSE FIRE-90L. Same size and bold pattern as an OS 61 or 91FX. Weight with the AAC sleeve is about as good as it gets at only 20 oz :) If you want a screaming engine and full pipe, this is the way to go. The engine is also available as a side exhaust.

Having said that........

That application appears to really want a heavy prop. Maybe a scale type 3 blade prop. In that case, I would recommend the Jett 120L. It is the same size and only 1 once more than the 90L FIRE (weighs 21 as a FIRE-120L). It is not designed to scream...... runs around 10000 rpm, but will turn a lot of prop, and does not need a highly tuned pipe to do it.

Another option, if you really want to save weight.....and don't need a lot of RPM....... look at the BSE 76L. Similar to the Jett 65L noted above, AND the sames size as the 50 dave originally mentioned, this has more power than most 60 engines..... will turn a 14x6 at 10000 rpm..... but is only the size of an OS 46 !! Weight for the FIRE version is only 13 oz ! Again, not a screamer engine.... has a practicle RPM range of 9500 to 12000 rpm range, and does not typically use a tuned exhaust (same is true for the 120L), so there is great variety in prop selection. (I currently have a 12x6 3 blade running on mine to gather some data, and the engine turns that quite well). If the original of this plane used an ST61 or something like that, definately look at the 76L.

For the 65L and .76L, there are some nice carbon pipes, used for control line stunt versions of these engines, that might be suitable for this application.

Just a thought, but you may want to consider a helicopter type of heat sink head from which ever mfg. you go with. It will help ensure cooler operation.
