I don't think that Sara has ever "bashed a manufacturer". My impression of her posts is that she says it as it is. You don't have to like it and you don't have to agree with her and because there are more people on RR with Jetcats proves nothing.

No, I wasn't saying that JetCat is a fraud. JetCat designed the single stage helicopter, Wren designed the two-stage helicopter. Simon Peckham was working with Wren and then took our two-stage designs to JetCat. I believe that's why the two-stage JetCat designs are designated as SPT and SPH - the SP is from Simon Peckham and his SPS turbines (which were all Wren designs). Wren had to take legal action in Germany to prevent Simon making direct copies of our engines, and the JetCat two-stage designs are not identical to the Wren.

Simon was JetCat UK for two years, but was dismissed by JetCat over a year ago. One of the reasons for his dismissal was that they had discovered that he was not, as he had claimed to be, the designer of the Wren two-stage engines and gearboxes. JetCat took legal action against Simon over this and other matters and they asked Wren to provide documents and support for them in the case. We were happy to do so.

Er dont quite understand the comment there, the fact there are more people with one brand over another speaks volumes.

So you would not say then the fact more poeple have raptors over other makes doesnt say anything about the raptor brand - wake up and smell the roses.

anyway before this thread deteriates rapidly,

it was about the reasons of why have a turbine.

It is the power and for people like me it is the adrenalin rush the pop as the gas ignites and the turbine runs up.

Wether its WREN or JETCAT the thrill is the same,

If you have the confidence go for it, cos they are precise bits of engineering, and dont require constant mixture adjustment.

for me, until i pass my PPL on hellies this is the closest thing i get to flying solo :-)

i would also add

the only downer asbout having a turbine is not many have them in my area, so i end up being segregated from the rest, and i end up flying alot of time on my own.

If you go down the turbine route it helps if you can find a fellow turbine flyer, then you can share info and help each other along the learning process.

Up here in Gravesend i am the only one with a turbine hellie, it can be quite hard to get help, and most of the time it means ihave to travel quite a distance to find that help.

Good luck anyway

No, just telling the truth. Check with Bob Johnson if you don't believe me. I don't think any manufacturer would want to see an accolade like the one from Coolrunnin (quoted below) wrongly attributed to their competitor.

"Whatever the powerplant though, Bob really did throw that machine around very accurate smooth routines. That also has to be one of the fastest helis in a straight line I have seen - it was way faster than my Cuatro gasser!"

If I wish to post on this or any other thread that is my choice to make, not yours. I will decide where, when and what, not you.
To clarify, as you did not appear to have read the post correctly is that "because there are more people on RR with jetcats proves nothing" never mentioned Raptors as far as could tell.

Anyway, you know nothing about my fleet, so mind your own business and if I wish to defend Sara that's my decision.

argumentative as always.........

Your reasoning is flawed,as is your so called turbine fleet, as was explained by analogy of a Raptor, i think you need to read my post accurately

i used the rapor as an analogy, the fact they are the most popular pod and boom machine speaks volume,when you said as above the fact more people have one brand over another means nothing, ER IT DOES!!

nice to see your Bolchy arrogant attitude coming through as always.

with Jetcat - the fact this is the most popular speaks volumes, the fact more people have them also speaks volumes..... i rest my case.

but
what i loved about the wren is help and info was a phone call away, i wish we had the same level on Jetcat cos here in the UK there is no one and my german is awful.

good day all

Sara, It was the dig at Simon, not the product

Matt, Until Wren put serial numbers on their turbines, there is no way of knowing which is the most popular.
What do you mean by no help in the UK, how many times have I given you accomadation, on the visits you have made, thats one service even Wren do not offer (yet)

Well

i never asked SARA, depends if she likes young Fit chippendale blokes

as i say to my wife " i have the body of a god" to which she replies very quickly "yes Buddah"

MAYBE SARA has expensive tastes! but then i would say if did take her out for a posh meal and a high class restaraunt, my chat up line would be whilst in this high class place to eat " if you were on the menu you would be a MC Gorgeouse" lol

Oops, my bad!

Sorry Sara. Glad to hear that everything was sorted out in the end and the right person was prosecuted for his dishonest behaviour.

My main point of the impressive 3D displays Bob puts on with his turbine Cuatro definitely stands though

"because there are more people on RR with jetcats proves nothing"
i have to agree, the only reason theres more jetcats on rr is because they fit into scale better than the wren, however these mechanics are not free turbines and im sure that if wren done the same as jet cat and have a direct drive system then yes there would be more wrens, but wren doesnt instead they do what the full size do and thats the gas turbine with a second stage which in my opinion is a real setup.

oh and the reason i like turbines is because apparently its ok to start them up and fly from the pits, provided your doing a scale manouver. (and i got that information from a scale expert)

Darren,A little knowledge, in your case, is misleading
you should look, at the Vario scale helicopters, you will find, there is a Mill MI-2, also the Skycrane
Both these scale helicopters can be fitted with the SPH5 2 stage turbine, ( a real set up)
Also Simon Peckham flew a Long Ranger fitted then with the SPS 2 stage turbine, at the Vario flyin at Kevil, a couple of years ago
These are 3 scale helis that use the 2 stage turbine, there may be more, but being an expert, does not mean, you know every thing

peter you are right the jetcat 2 stage is in a couple scale models.
perhaps i should word it another way, if makers of fuselages such as vario had the option to use the wren with out modification (like rotor tech in australia) then i wouldnt doubt for one minute that a lot of people would use this setup as its easier and less expensive to maintain a wren than it is to have package up a jetcat send it off and wait a week for it to come back plus the cost of the service?.

easier and less expensive to maintain

It is not the make of fuselages, that dictates which turbine is used, it is the makers of the mechanics
Lars Zander, has designed the M mechanics for JetCat SPH5 2 stage turbine, where as the Australian mechanics are designed for the Wren
2 stage Turbine
HobbyParts has designed 2 sets of mechanics which can be used for either the JetCat or the Wren 2 stage turbine,both could be used in scale fuselages
Again very misleading comments on servicing and costs, unless you have owned both JetCat and Wren, and, had to have them serviced,and repaired how can you comment on which is easier or cheaper to maintain

just because i dont own both does not mean i cant calculate the running cost of both.the fact is its cheaper to replace all the bearing yourself in a wren than it is to send of a jet cat and have the bearings replaced.
as for the hobby parts fitting in a scale, i have no doubt they do but without extensive modification to the exhaust and a bit of a mod to the fuselage its hard to get the scale apearence.
but then my idea of a true scale heli may be difrent to others. as i would like to scale such rotortechs jet ranger with the power plant hidden away and not so when you open the side doors you see a loom of wires pipes and mechanics.
but then thats just my opinion.

[quote]as i would like to scale such rotortechs jet ranger with the power plant hidden away and not so when you open the side doors you see a loom of wires pipes and mechanics.

have you ever actually seen this machine in the flesh ? flown it ?

you have no idea at all, what you are on about, you have never built a scale and have never flown a true scale model, and only hoverd a turbine, for a brief moment - (your words in a prev thread)
so where all this wonderful experience and knowledge comes from is amazing.

how can you calculate the costs ? have you sent a turbine in to wren to be serviced? have you sent a jetcat to Germany ? and paid for a full service ? er i think not,

[quote] i have no doubt they do but without extensive modification to the exhaust and a bit of a mod to the fuselage its hard to get the scale apearence

what do you base this on ? i have both hobbyparts mechanics, and with a little amount of adaptaion on the exhasut it will slot into it.

but you are correct in regards to the Rotortech the turbine it tucked away nicely and as Sara pointed out to me in another thread it is in the correct scale position.
so yes you would have a correct looking scale machine, but as a new person to scale turbines i owuld worry sickc about getting the right pitch and throttle curve wihtout the use of governer.
this sadly is where jetcat wins hands down.

so info is misleading, mate!

no but if you knew the machine i was talking about you would relise that the pictures of it say it all. nothing in the front or rear cabin apart from the scale cockpit pilot and seats!!
you have no idea at all, what you are on about, you have never built a scale and have never flown a true scale model, and only hoverd a turbine, for a brief moment - (your words in a prev thread)
hmmmm let me see yes they are my own words from last year not last week.
how can you calculate the costs ? have you sent a turbine in to wren to be serviced? have you sent a jetcat to Germany ? and paid for a full service ? er i think not,

so info is misleading, mate!
i didnt say send it away to wren i said service it your self. to service a wren myself cost me nothing but the parts , to service a jetcat it cost you the postal cost the parts cost and the labour.

p.s yes thaks for posting the pic of my wife. i keep on telling her its not that wide.

Again, you lead with your mouth, and do not do any research, look at the JetCat Germany helicopter turbine page, you will find a set of mechanics PHT3/3 this is a set of mechanics with the turbine mounted on the top at the rear
i cant calculate the running cost
Is your calculation any better than your spelling
my idea of a true scale heli
MY idea of a true scale heli got me a second place at a national event last week, do you have any photos of any thing you have built
when you open the side doors

This is what I see when I open the side doors

thats just my opinion.
Darren thats all you are an opinion
