the highest i could get mine was 980rpm
That's about where mine is at but I have seen 1200. I am running the HP grips on all of my XLV's and XLC(which isn't built yet due to lack of a turbine :rolleyes.

I gotta say that having so many blade sets and head parts, I keep wondering what a 2.5 meter 5 or 6 blade system would be like. The XLC has a 15mm shaft as well but I'd want that beast on a 18mm or 20mm shaft. I'd hate to power that one, probably need three turbs...
I know of one flyer in OZ who is running his at 1480rpm, and the longranger 1380-1440 rpm
Is that a 2.5 meter rotor? OMG, why? Is he doing 3D? I dropped mine back down because I liked the softer feel, if you want to consider 1000 rpm soft with a 2.5 meter rotor. Not what I'd call scale.

I like the pics and I finally got to see the videos. Nice job to the both of you.

The beatings will continue until morale improves...

Hi DK,

the blades on the long ranger can be from 950 - 1.2 meters, it is a 1/5 scale machine..

i prefer the machine to be flying at the right head speed for it, rather than trying to mimmick full size with a slow head speed, the scale machines i have flown have been awful, fly like heavy dogs, under powerd, and have no tail authority unless you are in FF,

this is why i went for the Zealous, with a Wren, cos i set the head speed, not be capped by the manufacturer.

My machine will be running at 1250 - 1280, it is lighter and will be running 950 blades.. there are some tricks i know to make the head speed look slower than it really is...

I was practicing on my Predator today, doing long approaches and wagging the tail to mimmick full size... looked good, i was happy with it, and to be fair i dont care if it is comp standard or not, i am just enjoying flying a great machine with a great turbine...

Mayy

All The Best

In response to dezzasters post about forgetting to turn the oil on, I am thinking about a double, nay tripple failsafe for the gearbox oil pump. First would be a switch that as dezzaster says is connected to the fadec switch so if the pump ait running the engine aint going.
Second is an oil trap that holds the oil in the box should the pump fail but while the pump is working it simply overflows to the tank, just like a toilet water trap!
And thirdly.....some kind of oil sensor that detects the presance of oil in a header tank, if the pump is not on of fails, a light comes on, sirens sound and a small electrical charge is applied to your testicles. Hmmm maybe the later idea isn't so hot, might encourage some of the more twisted folks out there to fly with the pump off all the time......

I know someone who runs fuel/oil mix through his Zealous gearbox, much the same way as the new Wren. It actually runs cooler as well and is therefore idiot proof and maintenance free. (It does away with the oil sump, plumbing and pump electrics.)It required a little modification, but I think the rewards were worth it. Rotortech are aware of this mod but I believe they do not approve of it.

its a big ewilley mk2

ha ha good to hear from you matey...

I am down at bells we are burning the midnight oil, well he is watching i am building whilst wathing a plethera of films as he doesnt have Television, he only has it ocnnected to a dvd player to watch films...

I am tired now, we have cut a new shaft, i already fitted the torque tube, but on the zealous they cut it down to fit the longranger fuse, i have decided to keep it the same length as the cuatro 950mm, it meant we had to trim the torq tube as it waqs 1.9cm too long, so we have done that, and i fitted the bearings....

So a review so far,
the Zealous in its pod and boom formatt is the best scale trainer I have tested and setup, the turbine is on permanent show rather than hid behind a canopy and the machine is massive..it is built very well, the front of it,
it is an excellent machine to learn scale before the top of the mechanics as you know come off and go into the Longranger..

I was disapointed with a few things,
You still have to cut your own booms and fly bars...the fuel tank is an orange juice bottle, i only realised this after i ordered one from OZ and it came with a juice lid on, it is the same as cooking oil in the UK...

They are not popular in the UK so there is only 1 place that does a few parts not a full back up like i would expect for this kind cash outlay..

It is a unique machine, would i recommend it NO, for the limited parts back up here in the UK shame someone like Midland or even Wren did not take it on.

The longranger fuses are now £1800.00 which is a rip off for fibre glass which is all it is at the end of the day, this is not Rotortecs fault they use a 3rd party to make their fuses and they just put up their prices by a great amount. the front of the machine and the gear box setup is some of the best engineering i have seen and been shown, the head i would say is very nicely built and will take one heck of a blade being 15mm shaft and 10mm spindle...

Vietnamtastic!!?? What was I saying? How embarrasing
What I was refering to with that comment was that sound that the rotors were making as they diffused into the blade wash was awesome, absolutely awesome! You can only just about hear it on the video, but when you are there!!! Wow it's scary! I am well jealous... And well I really laid myself open with that kissing the Zealous shot!!
Should have realised what kind of comments would come back on that one, I'll get you all back.
