Magnum weed wacker....
Ohhh man...Ive just ordered my 3rd. magnum :-)
coming out of a 90dregee steep dive, and pulling up so it flatens out at half a meter over the ground is realy cool..... You just have to remember too pull back up again in time at the end of our field , as there are bushes and all kind of nasty stuff to get tangled into..... Well, I cliped a bush clean while going realy fast :-) the plane said WACK! , and it yawed a little, and then flew on. It wanted to roll verry little, so i decided to land :D . this is what I had done :cool: http://bornholm.adsl.dk/modelfly/fil.../Dsc00700s.jpg http://bornholm.adsl.dk/modelfly/fil.../Dsc00701s.jpg even the tail got it... http://bornholm.adsl.dk/modelfly/fil.../Dsc00702s.jpg SJ. |

Nice one SJN, I can't believe it kept flying.... must be one of the benefits of a delta wing I guess...
Well join the club, I'm at 3 now and I think a few others are too. Post the frame numbers, interesting to see the trends... You've got the right idea though going for another one.... at least you only need the wing/frame, should be just over €100 cheap at half the price! |
Magnum weed wacker....
well, the wing can easily be fixed......but it takes time.
Ill problably glass the whole model, and sharpen the leading edges.......when I have time for it :-). |

Nice, now you have a donor frame for a micro-b and convert this to a twin tail (F15 style).....
First turbine Magnum on the web..?? could be an interesting post. :-) |

How many lbs pressure would you need for awesome performance? probably not much..

I think the NANO BEE turbine engine that Jesus Artes is developping should be enough to send a modified Magnum into orbit...
SJ... maybe if you made the leading edges really sharp and very strong you could do the same thing without damage to the plane...:D and actually use it as a weed whacker...lol Unbelievable you were able to get that plane down without further damage... that wing is split almost in half... I once did the same thing with my 100" wingspan Telemaster when landing ... the only difference was that the bush stopped my plane... it made a 180° turn on the spot and landed on the edge of the field without further damage...cool sight... Too bad you don't have a video of this... or do you? |
Magnum weed wacker....
it actualy flew fine. I didn`t notice that the damage was that bad until I landed. I was just about to take another high speed dive, when I just thought that Id better land to check her out :-)
It was only when I turned off the engine, that it glided a little worse than normal :-) SJ. |

Bummer.....none in stock at the moment.....
Better fix the old one up imidietly :D http://bornholm.adsl.dk/modelfly/fil.../Dsc00703s.jpg Almost as good as new :cool: http://bornholm.adsl.dk/modelfly/fil.../Dsc00704s.jpg SJ. |

I just can't stop looking at those pictures!
This really gives you an idea of the HUGE amount of kinetic energy that is stored in even a small plane flying at these speeds... I don't even want to think about what happens when you hit a car or something like that... I think the engine of a Magnum at full speed can easily penetrate a car roof or something... scary... I just finished putting a new nose on my Magnum. And I put in a one-piece motor mount... much stiffer... My header broke also, and in retrospect this was caused by the crappy stock engine mount that always seemed to vibrate loose. Luckily I was able to weld (solder actually) my header back together. It should hold with the stiffer mount. |
Magnum weed wacker....
dont hit your car with it....that cant be good :-)
The stock engine mount is quite bad. I thought my motor was loose, but it`s only the mount bending :-) How did you solder it ? is it called silver soldering or something like that ? SJ. |

The product I used is called TECHNOWELD... ever heard of it?
Web site: Technoweld This stuff basically solders anything that contains aluminium. It is easy to work with because it melts at 430°C and aluminium at approximately 650°C. I first had my doubts about trying to weld this thing back together, but apparently it holds... :D Side effect of the rugged engine mount: the plane is MUCH louder, and the fuel foams slightly, but nothing excessive. I started cutting the pipe this afternoon (header is used up :p)... I'm still gaining rpm, but I'm not going to push it since it is about 35°C down here and I don't want to fry my engine. I can now hold the plane straight up, and if I let go, it just takes off straight up...cool... and all this on that tiny 8x8... I'm really starting to wonder when something is going to break in this engine... A Webra was never ment to develop this kind of power... |

Thanks Rudeboy, Ill look into it :-)
sounds like your engine is runnig perfectly for you. My plane is again fit for fight tomorrow :cool: I only had trim tape to play with. I hope I can see it in the air. http://bornholm.adsl.dk/modelfly/fil.../Dsc00719s.jpg |
