Default best Jett for a Patriot?

can anyone tell me what is the ultimate Jett engine for the .40 Patriot?

i think it is the .50 size engine (optimal weight / power ratio for that plane)

still a little confused about the performance of "sport" "BSE" and "fire" engines, what is the diff?

BTW i can't get the Jett website to work ... http://www.jettengineering.com/ ...when i click on the left hand side menu (any of the listings) NOTHING happens.... am i the only one to have this prob?[sm=spinnyeyes.gif]

i stand corrected... i finally got the Jett site to work, one has to "open in new window" instead of just :click:...oh well

so after reading the info it seems that the best POWER to weight ratio would be the new SJ-60LX (same weight as the .50)

but would it fit in the nose of the Patriot WITHOUT moving the firewall?

has anyone tried the SJ-60 LX?

thanks for any good info, V.

I think the new SJ-60LX would be the best without question. Same size as the SJ-40. Do a search in this forum and you will find several reports on this engine.

Many to include me use the 50 but that new 60lx sounds good.

thanks guys, i think i'll go with the SJ.50

looking at the specs, the 60 LX will turn the same prop 1,000 RPMs faster than the 50:

SJ .50 R/C with muffler > 16.5 oz prop 10x6 RPM 17,000 >$295.00

SJ .60LX High Performance > 16.8 oz prop 10x6 RPM 18,000 >$350.00

not sure the gain is worth $55 (to me)

The SJ-50 is one great engine. I had the SS muffler that would let the slightly smaller props turn up more. 9x8 at 18,000+.

I am installing a 50 on my Patriot as I type this. I had to extend the cowl/nose a touch to get it to fit. I am building the nose cowl area LOTS of carving. I was half tempted to just go without the nose cowl but I am doing it anyway. I can always hack it off if I don't like it.

I want the speed but I am just about tired of building this damn patriot.... As it was I didn't build it with retracts so it won't be the speedest bird on the block.

Vasek- Good choice! I have used the 50 for a couple years and want to get the 60LX to try... 1K more RPM's? Geesh, that would be awesome...

Ken- Be patient, it is worth it to have "something" up around the engine... Once you get a flight on her it will all be worthwhile and make complete sense.. (I bet)

Seems that simple doesn't it Sometimes it is. But for reference, those are ground/bench static. 17K is minimum recommended ground peak (prop selection) for the 60LX. Many more rrrrrrrs to be had in the air due to the SS muffler.

But you would not be disappointed with a 50 either. On the Patriot 40, we know it can do 120-130 easy with the .50 on it.
