HiAli

Picked up on this one late. Maybe someone is jealous of your "cult" status! One thing is for sure, 99% of us wish we had the flying skills that you have! I remember clearly your display with your L39 at the WJM here in South Africa in 2003, awesome, and you had no problem mixing and talking to us "mere mortals". You do not need to look far to see what you mean to most of us and see the smiling/laughing people(notafter the crash ofcourse!)around you. Iam not too sure if this is the case elswhere. You are invited allover the world to entertain and SHARE your knowledgewith others and thereforeholding you in HIGHRESPECT for your knowledge and talents! Please don't let this get you down. You posted this as information forus all to share and learn, and all you got was a kick in the n*ts and I know it hurts.Even if you use the best of everything, there is a lemon in there somewhere waiting to catch you out!

We are behind here in Africa but still try and learn using forums like this. I have built 6 Eurosports in all different configurations from single battery/Rx to dual everything and theyare all still going. I lost my first turbine jet due to a "noisy" ECU! Dual everthing would have meant squat! My little Roo has over 600 flights on it with single everything -KISS?

All my new jets have dual battery/Emcotec stuff in it as hopefully buys a little bit of reliability/redundancy. Hada friend crash his dual everything due to a faulty charger, yes many possibilites and we need to take them into account. We are all concerned about safety and would hateanyone to get hurt.

All of us know that there was no ways you would pull one of our "Up elevator" stunts. If there was any way you could have saved it, it would be back in the workshop charging for the next flight!

BTW - The colour scheme is awesome!

.

I know how to guarantee no battery or radio failures, I'm gonna start flying Turbine powered Free Flight!!!!  Trim flights are bound to be a bit of a challenge mind you.....

Sorry about the loss Ali, did you ever determine the actual cause?

Regardless of all the test flights, one RX , one battery a model that BIG !!

Can you imagine the impact it would have on the hobby, if that model crashed into the spectator crowd at a public show like Woodvale ?

Biggger models have crashed into bigger crowds and yet we are still here.....

You have to employ a little trust that the pilot, right from the very start of the build to the moment of the crash, is going to do everything he can to make sure that it if does happen, then it happens safely, right were it might be argued it is expected to happen, in the middle of nowhere and away from anything killable.
Re the Woodvale reference - I'll avoid mentioning the benefits of crashing on scousers as (as a fellow Manc) I feel i know where you are coming from.

Ok then Union, why is it different that the model is as large as it is? Why is it different to a smaller model? I have seen plenty of what I guess you would class as smaller models that would o as much if not more damage than the Hunter if it were to hit something? For me a high power EDF model is just as dangerous.. Where does it stop? I have seen many a model with dual equipment installs crash, and crash hard. Just a few weeks ago a large Jet crashed at a JMA event, and it crashed hard! Really hard. This was power box royal equipped. Then just this week the possibly the largest model fighter type jet crashed under testing. This was fully equipped with dual, if not quad redundancy.
As far as I am aware, all the model aircraft related deaths in the Uk have been with what I would class as " Club style" Piston powered models all at normal club days. I know this does not prove anything, but it confirms that accidents happen. They have happened, and will always happen. To focus on a large scale jet and to say what if gets us nowhere. I see allot of flying in the UK, and I have to say I am more worried about the sub standard level of flying that I see sometimes than I am the equipment used. This to me represents a far more dangerous aspect of the hobby, especially in the jet area where more and more I see people flying models that they are maybe not necessarily ready for ( Skill wise )
This thread is a great example. In its pages we have a self proclaimed expert who attacks me and calls me dumb for the equipment install that I have chosen to use, in his opinion a single battery installation may have been responsible for my crash ( Which damaged nothing and represented little risk to any one or anything) and thats despite this equipment choice being used worldwide in a number of models with similar if not more loads on the batteries. Oh and just in case anyone missed it the battery has checked out ok after the crash.
That self proclaimed expert is the same man that due to pilot error drove a model through the roof of an aircraft museum hangar, causing damage to property and risk to humans.
Strange how fate all works out hey?
Regards Al

First of all Union,
Why bring up an already beat up and dead issue thread. What Ali said is true, I would be more concerned with the pilot flying the jet than the jet itself and what it is equiped with. Take a look at the thread just posted with that twin turbo prop, here we have a twin prop driven jet engine, and the guy takes off while spectators are on the run way, would it then make a differance if he had dual everything if he hit someone, it was his maiden flight no less, that to me is poor judgement and if it was here in the states, that can cause him to loose his turbine waiver.
Joe C!!

Just as I had finally got over the terrible destruction of the "Fletch" someone goes andre-life's this thread

</p>

Anyone in particular ?



J

No Jas, This was not aimed at Dunc as its not his flying as such that scares me more like the landings. I think a few lessons on the Al's buddy box will sort him out. ( I had decide that one already)
It was not aimed at anyone in particular, just a general observation, but even with this, the more I think about it the more I think... How do you protect against someone flying a jet that they are not ready for causing damage. Just like how do you stop a model ( any model ) Causing damage to people or property. Some will argue that you should fly higher, or further away, but if you look at my Hunter crash as an example. In it's uncontrolled state if it were much higher and further away it would have come closer toward property.
The whole protecting the hobby thing my enforcing rules on flying is a toughie really. It might just be me, but on all my travels I tend to see more dangerous, or potentially dangerous situations arise in the locations in which I fly at in areas which have the more strict rules and regulations. ( and remember I get to fly at quite a few different locations with different riles and regulations around the world )
Again, I am not saying that one way is right or wrong, ( Just as I started this thread to show that the K.I.S.S installation route can fail just as the super complex redundant system route can ) ***** happens.... Everywhere, and to everyone at some time or another. For those that want to have a dig at me, or use me as an example in the case of the Hunter crash then so be it. For those I ask them to please remember how many hours per month, per year that i fly. How many different types of models I fly. Maybe even do like the full size guys do and log it in hours. Then divide it by how often I crash, lastly do the same for either themselves, or a flying buddy of theirs, and hopefully that should give you an idea of how seriously I take safety in my flying and my models.
I wanted this thread to show that it happens to us all, and I have no illusions that it will happen to me again... when and where, I dont know. For those of you that think it wont happen to you, I am deeply saddened as your majority mistaken.
Regards Al

ali all this negative feedback is ****e do all you ney sayers think he went out to crash a over 10k jet i think not why dont you all back off and pick on something elce regards jonathan

LOL just wait to bickley j !!

Hello i have a related question. I am building a rather large Saab Viggen.To have maximum safety on my narrow budget i intend to use two separate recievers. (35 mhz) Both recievers vill take power from two batteries with a switch on each. I have decided to split elevons into three surfaces on each side.Each surface with its own servo of course.My question is concerning the elevon setup. Blue marks one reciever, the other red.I am leaning towards the B version. What do you think?Jonas

</p><div style="margin: 0cm 0cm 10pt"><span style="font-size: 9pt; line-height: 115%">Out of the two I think option B is the only way to go, butwould you reallyhave enough movementto fly on only two elevonsinstead of the six?? You could of course flick it to high rates but by the time you realise what&rsquo;s happened it may be too late anyway. With option A I think you would be very lucky to get it down if one side of the radio failed.

<div style="margin: 0cm 0cm 10pt"><span style="font-size: 9pt; line-height: 115%">If you had 4 elevons instead then it would be an easy decision with one on each side running from each RX.</span></div>

You guys and your overkill power systems.....

Coppertop baby... 4 of these is all you need
Good for at least 70 flight before I make a run to Walmart for a fresh set!
Sorry for the loss Ali, kick ass bird....

Ali we got you covered..
just wear this
anti sun and makes great protection

Cheers you two... At last this thread brings a smile to my face!

Sandor's got a nice shiny helmet !

yes....

so did you finally maiden your XL?

Thanks Jason! I think you are right. Maybe i should just put another "3rd"reciever to the outboard elevons. or use four elevons,i dont know. Have to put a limit somewhere! I never have had a reciever give up on me though. The only thing killing my aeroplanes apart from my own stupidity have been a Nihm pack not being able to supply all servos with power. That cost me my first DF machine.Since then i am having a hard time to trust these cells. Other Nihm-packshave died, but on the ground thank god!The viggen will use Nicad packs. These are a known factor for me. Sometime i will have to use other cells, i know! But not just yet, and not on something that may have other difficulties. (like triple engines e.t.c)All in all i think it is wise to streamline all systems as much as possible, the Kiss principle i guess!Jonas

Don't be daft Sandor, he sold it before he had to fly it.

Yes the XL has flown, I have flown it.
It is going down to Bickley tonight to be looked over by a possible new owner.
It's just too big for my workshop and crappy car so has to go.

Sandor, bring some Schnapps please.

will do ..
