....how could the starter motor be stuck on yet nothing happened for FOUR minutes.

aparently it was locked solid.

Is this Wasp using the Taiwan made 60mm Jetbeetle turbine wheel ?... if so what level of certification does it carry...?
Also ...Have'nt there been Several.bearing failures on wasps..?

the facts are:-
rear bearing failure
fried ECU
fried starter motor.
the starter motor will act as a generator if it is connected to the compressor nut vus sending high voltage to the ECU so at some point the starter coupling would have had to have coupled with the compressor nut or how else would the ECU have gotten fried?

i would have thought that each wheel will be xray'd, although the wheel hasn't failed so that can be ruled out of the argument, blades we're lost when the rear bearing failed and the disk was intact.

.... it lost a third of its blades the rest were bent also the rear bearing was gone - so did the turbine fail distroying the bearing or did the bearing go distroying the turbine

Yes ..The oil flow arangement is very odd..thiers no air to assist the oil flow...

RE: Wasp update
Hello Paul,
Some friends have mailed me pointing to this thread.
Please STOP your tries in to accuse the Ecu of the problems of the engine.
Don't try to confuse the readers pointing to something outside the engine. It is clear that something failed, I have my own theory from the reports from first hand witness, but I leave to PH this. About your theory:
1. If ecu fails to disengage the starter: Ecus aren't God, they only can cut the supply to the starter. The only weird thing that the ecu can do is not stop the starter, very unlikely as the ecu short circuit the starter to brake it, but anyway, once the rotor rpm is higher than the starter RPM (say 30.000RPM for a Speed300 motor) the bendix disengages itself automatically. It is a mechanical thing, when the torque goes inverse, the bendix retracts, nothing to do with the ecu.
If the bendix keep stuck (mechanical problem, it is a part of the engine, not from ecu) the only think that happen is that the torque of the engine at low RPM (say 30.000) can't drive the starter motor with its terminals shortcircuited from the ecu. Again, the torque is high and inverse, the bendix should disengage, if not, the RPM fall and some fire exit from the exhaust. No way to arrive to idle.
Supposing that the engine can arrive to idle with the starter engaged....that is a lot of supposition... Let me know what starter you use that can survive 4 minutes at 150Krpm. And the ecu should have survived 4 minutes at 50V of back EMF... that's reliability! Not many appliances allow a voltage 7 times higher than nominal...
And the suposition that a starter shaft (a fault outside the engine, again [&o] ) with his tiny 2mm of diameter can upset the preload and damage the bearings is ridiculous, sorry. No way that it can hold full 4 minutes and do enough force to upset the preload... and this force should be against the engine, just inversely as the sense of the bendix...
Why the starter and ecu are fried? Simple. As soon as the engine begin to fail (yes, the engine failed first) (say blades lost, say bearing, say the pilot doing a loop at +40g, say whatever you want) the shaft begin to run eccentric. As the compressor nut sit inside the bendix with a small clearance, this eccentricity made that the compressor nut contacted to the bendix, driving the starter at full RPM. The ecu keept the starter shortcircuited, but the instant power was too high for it and fried both, ecu and starter. This was just after the bearing fail, and during the time that the engine run until stop. Also, any tries to cooldown the engine trough the ecu withn the starter fried could have damaged the ecu too.

Gaspar

RE: Wasp update
Hi,
If some people would read what I said I am not slagging phil off at all and I do think the engine will be sorted there is only one fault on this engine IT HAS BEEN RELEASED TOO EARLY if your thinking of getting one great get one BUT all I'm saying is wait a little WHO WANTS TO BE A BETA TESTER. This engine at the moment is £1000 to some people thats alot of money - so they would have save to get it - and all they have is problems I don't think thats right or fair - I had a right old rough time and spent alot of k's to get jet success I wish I'd have had help and a resouce like RCU at the time not every body has the resources I did. This forum is great and here to help everyone novices and die hards. It should show good AND bad , do's and don't. And if people knock me for trying to save people money and telling it like it is then I REALY DON'T CARE the 'LET THEM GET ON WITH IT' attitued is for the selfish not me - I bought one of the very first wrens - it was so long ago it had a speed controller not an ecu - but it worked I put 40hours+ before the bearing went (I know I left it too long but hey).
Lets face it there ain't no thought police yet so!! until there is I'll be here.
all the best

No Paul that can't be right. Rutter the Nutter said the engine just 'BLEW UP' in the air. He wouldn't go off half cocked would he? He wouldn't bad mouth something whilst only knowing half the facts? No, surely not

Do know most of the facts but I wouldn't need all the facts only knowing a few would be enough thanks . Half cocked ?? this happened over a week ago.

I actually feel a bit sorry for Phil. He's a nice guy and a gifted turbine engineer who is just trying to make it in a very competitive turbine market. A thread like this could do a lot of damage to his business. The thing is, I can not name a single major engine manufacturer that has not had a turbine failure apart from bullet proof Sophia’s and JPX's. Turbine wheels fail for loads of reasons and not just because they are of poor quality.( and im not saying the wasps wheels are poor quality)
A little note to hill seeker. Maybe you should have thought twice about raving on about the wasp at this stage. It just gives people ammunition when things don't go perfectly.
Take it easy.

RE: Wasp update
every engine has problems. i myself have witnessed 3 other different engine types do similar things. with over 20 engines in this country running this was the first real problem which is pretty good i think for a new engine.
I know Phill has been very upset about this failure and has done a lot of work to make sure this will not happen again.
Its strange rutterthenutter that you always seem to criticise this engine. it makes me wonder just who's ass you are kissing.
I rave on about the wasp because as i said in my opinion it is a great engine that i have faith in which you need when flying expensive models. other engine types have let me down but if you read threads on other engines i have also praise behotec and frank engines and also think wren are responsible for bringing quality engines to the masses at a good price.
i don't think RCJI will put a spin on things what have they got to gain.
i tell you i sometimes wonder if some of the users on here are just school children messing about due to the imature nature of them .
we all enjoy the same hobby so why do people have a problem with new or lesser known products.

using my thoughts of what has happened to the engine i came up with the idea that maybe the ECU caused the fault, my idea was more than likely incorrect as the reply from Gaspar gives another explanation as to the possible cause of the failure.
lets all try and get on and hope that the reason for the failure is found and recified.
sometimes you learn more from failing than suceeding.

The engine failure wasn't the first problem in 20 the combustion chamber didn't work properly also I know of two other engines which run hot and lower power both engines have an acceleration delay of over 50 on the gaspar fadec ecu that like double of any other engine. This is to stop them flaming out. so thats at least 15% of his engines have issues ?? ?? ?? ??. As I've said I've heard phil is a great turbine engineer and he has no doubt an engine with great potential but his timing has to be questioned to highlight to people wanting one to wait. Most other turbine manufacturers have a very long testing out in the field with non paying test pilots (one tested for 18month - 2 years) and as you said you flight tested the very first one only months ago.
Heatseaker if you say things which look incorrect expect them to be question good people MIGHT loose money over this.
all the best

Eeerrrr not alot the two engines (plus the tested one) I know of have were flaming out regulary and as the first flight was only a couple of months ago MMMM - THAT AIN'T ENOUGH . Im sure there are happy customers in the 20 and if their engines are fine pipe up and let us know. If they do this just proves there are inconsistences in the design A SURE SIGN OF UNDER DEVELOPMENT AND TESTING. I'm 100% sure he will sort it all out but not at the expense of the uninformed people/customers that in my opinion is wrong.
If 15 out of 100 £1000 new ARF F15's from a manufacturer were folding in half in the air wouldn't you want to know before you place your order - whats the difference both will cost good people money.
Is my opinion wrong ??

If they do this just proves there are inconsistences in the design A SURE SIGN OF UNDER DEVELOPMENT AND TESTING. I'm 100% sure he will sort it all out but not at the expense of the uninformed people/customers that in my opinion is wrong.
If 15 out of 100 £1000 new ARF F15's from a manufacturer were folding in half in the air wouldn't you want to know before you place your order - whats the difference both will cost good people money.
Is my opinion wrong ??

as far as i'm aware it has had quite a lot of flight testing.
nothing like 2 years or anything like that but it has had flight testing.

ps ONE MORE TIME I'm not questioning ability its only the release with no real flight testing.

the reason the other customers aren't piping up would be due to them not being members of Rcuniverse, or if they are members then they haven't seen the thread.
plus people have got better things to do with their time that mess around on the net, the only reason i'm on here is because it's raining outside as usual, TV is crap and i've completed tomb raider legend on the playstation, otherwise i'd be out there burning jet fuel.......actually i wouldn't because the local clubs in my area have banned turbines
, but thats another matter.i'd be out there flying something though or at my girlfriends...wink wink!

RE: Wasp update
Hi All,
I have to say i had two AECU's fry on me and know of two more from a local club that have fried. the AECU in question was an orbit,.... i still use them and have been VERY happy with the AECU's.
This is what happened, using a Wren turbine(full auto start) started the turbine was at idle must of run for at least 2 minute as i set up the camera to look in the hot end went to raise the rpm to 100k and all was fine for another minute or so then the starter motor over heated as it had been touching the spinner, this almost stopped the turbine dead and would of if i had not switched the turbine off.
The second one the starter coupling failed and locked onto the spinner this time i was running a kj66 the turbine must of run for 5 minute the only thing i notice was it was down on power,... and then a big flame out the back.
Landed and had a good look the turbine the starter motor/aecu/coupling had all been damaged and the turbine would not turn over when i got it home and had a look inside the turbine the rear bearing/turbine wheel and ngv were all damaged and all had to be replaced.
At my local club one guy started his turbine as normal and tried to take off a few times but could'nt understand the lack of power and once again the coupling was the problem and also burnt out the ecu he was lucky no turbine damage.
This is what has happened to me not here say but the facts. I do not know if this was the problem with the Wasp as i was not there, We should all wait for the FULL report on the turbine,........... as it may just of been a sticking coupling or a turbine wheel??. so let the experts do there thing .
That is why we SHOULD wait for the fact's
Just my 2 pence.
