Getting ready to order a turbine for my 1/6th skymaster f16. Thinking of a Jet Central Mammoth or a P200. Any other ideas let me know. Please post your vote and any information that might help me to make my decision. This will be my first turbine so ease of use durability and customer support will be important. Thanks as always.

My personal choices would be the Merlin M-160 as first choice for that airframe, in my opinion its simply the best overall performing turbine in the upper 30 lb thrust class (38 lb) according to RCJI and the GTBA with near on 40 lb on tap and offers stunning acceleration. Value wise and performance specification wise its hard to see past the the M-160 for me, at present is still only available in gas start version but will be upgradable to kero easy enough, when available.... http://www.jets-munt.com/pb/wp_15e5d...72600365430117

The EvoJet Booster 160 is similar price and has just "slightly" less thrust @ (36 lb) although its advantage would be offering the best kero start system in the industry and is another great value gem and very popular in Europe especially. http://www.orbit-electronic.de/

Kingtech's new K160 will be available soon also and will be a world beater price wise, should be rated at approx 36 lb also.

Hmmm then there's Wren XL 200 and the bullitt proof AMT NL Peggy these are two more that are very worthy also, a little more pricy but WELL worth a look....

Great info thank you. Took a look at the other companies websites. Really like the look of the AMT stuff. Bulletproof is always a plus. Can you tell me if the pegasus would provide enough thrust or if i would be better off with the olympus. Since it is my first jet i want to have plenty of power to get myself out of trouble. I only have the stock kevlar tanks at the moment and i am concerned that the olympus might suck the tanks dry to quick. any thoughts

Pretty much they are all very reliable nowadays and I would say the top brands are near all on par from a reliability perspective. After sales service is also very good from all the major manufacturers, so thats not a huge deciding factor for me. #1 deciding factor for me is overall turbine specifications when compared in any given thrust class. I look at max thrust, acceleartion/deceleration/residual, operating temperatures, fuel consumption, service intervals, installed weight #2 purchase price and cost and downtime for service/repair longer term.

The AMT NL Pegasus would be just fine, as would any of the others mentioned in the SM F-16. If I was to nitpic and look for any other downside with using the AMT's it would be likely overall installed weight and more bulky systems electronics. The AMT NL Oly is a beautiful engine of that there is no question although it would simply be serious overkill in my opinion for this airframe and not required thrust wise @ 50 lb+ Installed systems weight for the Oly and fuel required would be much higher as well... its much better suited to say a 1/5 scale F-16. I have seen plenty of these larger 1/6 scale ARF F-16's flying on the mid 30 lb thrust class turbines and they perform just great.

For me 'personally' the bottom line shopping list for whats available today to suit the bigger 1/6 F-16's such as from SM, Fei Bao, Fly Eagle would seriously be between the Jets Munt Merlin, EvoJet Booster 160 really it comes down to overall product quality v performance v longterm service/maintenence ownership cost, all of which should equal best value for money. Jet Cats are in the equation of course as well but when overall performance (thrust/acceleration/fuel economy) and more compact systems electronics and then $$ price are compared, the Merlin and EvoJet to me anyway still look to be much better overall well "proven" performance/value option.

Hope this helps....

It seems i need a little education. Thank you for replying to my friend on RCgroups we posted on both sites to make sure we got all the info we can. he will be helping me with the build. I understand that there are many different ways that these engines start. Electric start kero start and what appears to be some kind of gas propane i assume. I have looked into this matter and i see that all these engines automatically some just need a gas which i assume is to spool up the turbine. I am probably wrong. I have heard that the engines that use the same kerosene for a start can have problems with startup of glow plugs. Is there a simple system that lets you fuel the jet air up the tanks wiggle the throttle stick and start the engine. If you could help me clear some of this up i would appreciate it.

YouTube - evoJet Booster 160 Start and Run Test #2

found that vid of the evojet. I cant see any extra starting gear. I am sure i am not making my question clear but if you can do your best to help me i would appreciate it. It clearly sounds like you got a good grip on this stuff

Hi Hansen, kero start is now seen as an advantage by totally eliminating the need for gas/propane which has been the standard starting method incorporated for a number of years previously by most manufacturers on all auto start turbines.

As to prior concerns encountered with certain kero start igniters, most commonly discussed are the early JetCat conversions, primarily the longevity of the JC kero igniters. I believe JC have improved their igniter design, although Iam not upto speed on all those specific details I will admit. I do know this and that the Evojet's differs from those in that it uses kero start system that is completely internal and is a 12V kero burner based on a automotive design that is used for large internal combustion engines. The more common/sensitive problematic kero start systems have been generally external "glow plug" retro fit designs and rated at just 6V. The EvoJet Booster engines use the SFL12V fully enclosed igniter system and this is considered to offer 100% trouble free lifetime service. EvoJet are offering a 5 year warranty on the Boosters which would tend to back that theory up pretty well I reckon...

I have have been flying the EvoJet Booster 130 myself for a while now and Iam very impressed, it sure is nice and seamless watching the complete start occuring at the flip of the stick/trim. As long as your fuel line is correctly primed its that easy.

If you have any more questions feel free to ask here or email me directly- jetfx@bigpond.com

3W170!!!


awe crap.... wrong thread.....


sorry

[selleri]

The SX series from JetCat have a internal burner... there is also that new P200SX

The new Evojet 160 is very neat in that it only has one kero line to the engine and one solenoid while JetCat has two fuel(one for the running fuel and one for the starting fuel) lines and solenoid for each.

[JET FX]

Yes very neat..... heres my EvoJet 130 install in my sport jet.

[GooseF22]

I saw the SM 1/6 fly very well on the P160SX. So any good consistent mid thirty's would work.

Check out the Wren 160 as well. Its propane start.. but it is light weight. I also have seen guys fly with P180's and larger but you have to carry more fuel. tradeoffs....

Call Rob Lynch at BVM or DAvid Ribbe at Horizon hobbies. Both fly the Crap out of theirs and get some answers first hand...

I will be using the Wren 160 on my Jet Legend 1/6 F-16..

[JET FX]

Kingtech also have their new K160 due for release VERY soon another mid 30 lb thrust option. Price will be lower than the others and it will have a lifetime warrenty also....

[ckeene9]

We here at the BVM factory recommend the P-160SX to keep it light. This plane flies awesome on that, will do 200mph, and will allow it to fly at high alpha.

We are also using just 2 of the saddle tanks plumbed in series for a lighter weight set-up. Don't know where you're located but give a call to the factory at 407-327-6333.
