Hello,
I am on the fence about changing my turbine order. I have been waiting for two months for a Jetcat P-70 that is on back order. Artes turbines are getting great remarks from RCU members and I could have one in a week (no waiting). So, what do you think? Wait for the Jetcat, or go Artes JF-50 Bee? The engine will go on a BTE Reaction 54, my first jet and my first turbine.

Get the Super Bee. I just got one and love it.

Beave

P 70

Only way to Go..... If you Ever need service their only a phone call away.

The P-70 is a sweet engine.. You can also use it later in middle sized airplanes, like the delta wing things, Bobcats, Bandits, etc.. with very good performance.


Enrique

Flip the coin and see. They are equally good. Seen my friends are flying both and got great fun and reliability out of both. I have an Artes Falcon and having a lot of fun with it.

Mike

if your considering the P-70 then also look at the Artes Falcon.

Same size motor but a lot more thrust.

Got both turbines !!!!

You need to think about what your second and third jets are likely to be and buy an engine with those in mind.

The Bee is a good match for a Reaction 54, the plane was designed for a 14# turbine. A P-70 is heavier and puts out 17.5#, which is more than that plane needs, but will also fly it fine.

Thanks guys, I appreciate the advice. I received an IM from Mr.Eric Clapp of Artes Turbines reguarding their engines and service. I think that is a nice hint of how good their customer service probably is.

Thank you Mr.Matt for the IM expressing your concern. I have to say that I like the 17.5# thrust that the P-70 offers as far as using it in larger planes later and the extra power it would provide on the Reaction 54. This and the Jetcat reputation for quality and customer satisfaction is how I made my choice for the Jetcat. Sounds like the perfect choice for now and later, however I am without an engine and the JF-50 Bee is in stock , cheaper and has a lifetime warranty. Hard choice here.

I think that you can't compare the Jetcat P-70 vs. JetCentral JF-50 Bee, the P70 is much bigger than the JF50. You should compare the P60 against the JF50, the P60 is still a bit bigger diameter.

You should compare the P70 to the falcon, the falcon is a bit bigger than the P70, but much closer of size than the JF50.

Joe

P-70 3.8" diameter
Falcon 3.89" diameter

Not much bigger


Actually though if you think about it, his comparison of the Bee and the P-70 is not all that far off.
It's a 14lbs turbine at 6000ft.
Chances are he can get 15lbs of push out of it.

The saved weight over the P-70 makes up almost the same thrust difference.
Lighter motor, less fuel load, more flying time.

That is a very good point and you are right that the P-60 is a better comparison to the JF-50, but the Falcon is 22lbs. thrust. Far more that I need for a R-54, so that is why I compared the P-70 and JF-50. Both of these work for my application and cost is only $200 differance between the two with the P-70 being the more expensive.

turn down the rpm's on the falcon to 16lbs of thrust and it will run forever

One other advantage of dealing with Artes is that you being on the east coast, your service turnaround time will be quicker. I sent my P-60 back to California for service after the EGT probe/amplifier died after only 3 succesfull starts. I sent it priority mail which took 3 days to get there. They kept it for another seven and then shipped UPS ground which was another five days. Basically, three weekends of flying were lost in addition to $45.00 for shipping and insurance. Even if the turnaround time is the same, shipping time is cut in half from TN to FL. BTW, I have the P-60 in a Reaction 54. You will enjoy it. When does JC expect the P-70 to be in stock?

Marty

Well, I just got a call from JetcatUSA and the P-70's came in today. I completed the order for the P-70 because I feel it will serve may needs better at this time. Thanks to all for everyones input and thank you Mr. Eric Clapp of Artes Turbines for your interset in my needs. Thank you Mr.Matt for your help as well.

I am glad everything worked out for you, the P-70's selling well and are running_really_well. The performance from this latest shipment was some of the best ever, I will PM you the performance specs of the one you are getting.

Let me know if I can be of any further assistance!

Regards,

I can only say one bad thing about the P-70. It has an incredible turbine lag. Twice the lag of my P-120's. That being said, I bought another one off of Tam to put in my Super balsa bandit.

Jetcat is (>90% of the time) always answering their phones and they get to know you on a first name basis. Turn around time is very reasonable (I always find it kinda slow, I want stuff RIGHT NOW!!NOW, NOW, NOW!!!) I had a similar waiting problem earlier this year so I feel your frustration.

It sounds like you got the P-70. Enjoy and burn tons of Jet-a!!![sm=thumbup.gif]

My P 70 has a spool up time of about six seconds from idle to full throttle.

Yup....

Jetcat all the way. Best ECU, service in the USA, bulletproof.

Matthewfox,

Welcom to RCU...

I meant welcome!! (I missed spelled it...oops!)

Both my Artes Bee and Falcon have spool up times of about three seconds from idle to full throttle. That was one reason I bought them. The almost instantaneous throttle response could save your plane if you need to go around or to get out of a difficult situation.

One of the most remarkable RC events I saw was with my buddy's Super Eagle/Gripen. He came in hot and did a bad nose up bounce. The plane was falling tail down and nose at about 11 o'clock when he gave it full throttle. I thought it was a goner for sure. It got to about 6 feet off the ground then took off like a rocket. Yes, I know the plane is overpowered, but if that was a Jetcat in it the plane would have crashed for sure.

Joe

Though I currently own 8 JetCats, I do not think I will buy another any time soon again .. they are no longer tops in terms of performance. There are alternatives currently available which have more power, and better spool times in equivalent classes, and don't have as many issues as many JetCat engines are having these days. Look at some of the big jet events ( like Superman in particular ) and see which engines truly run reliably, and which ones are flaming out on people, or don't run right. I have been seeing too many people recently having problems with brand new engines, and even being made to pay for repairs on these new engines for these still not to work ... I have been fortunate and have personally not had any major issues with my engines, but I was not particularly thrilled on not being able to fly either my p200 or p180 until antistatic lines and additives were available ( this is what I was instructed ) .. and still don't have the warm fuzzys about the whole static issue JetCat ECUs are susceptible to …
