A hornet is a bug... Hey I want to know who came up with the name Fagot for the Mig-15 - [sm=lol.gif]

NATO... you don't give your enemies scary names!

NATO eh???? hmmm I think I maybe a little scared with a Fagot chasing my tail..........

Speaking of the bugs stall characteristics... Iam pretty sure this bloke would be able to shed further light on what not to do at lower altitude.... As soon as he's released from hospital anyway (he's ok apparently) [X(]

. . . and Lucky. Speak of the devil, Glad it looks like the pilot made it, shame to lose the jet though.[]

Well.....we flew our FB F-18F today and got three more flights under the belt....

Bug likes to be flown on landing with gear deployed, flaps deployed to some 35 degrees and brought in at half throttle on a 28lb thrust engine . So drop flaps and gear on the downwind leg when the model is just about to cross you half way towards the base leg and trimout its glide angle of descent...bring it in as described above and you're pretty much safe for a nice and smooth touchdown.

Control the descent angle with throttle management and when above runway of some 20 inches flare out gently...

The models stall is very predictable ...at least on ours , it starts rapidly sinking nose high , for recover it needs quite allot of power.

talking about bug bites... what a mess! maybe one engine failed?

and amazing to see how the ejector seat seemed to know where to go while ejecting...fortunately the bug driver was unharmed as well people on ground.

Are we not off topic here.....

More Bug bites

The last video is very characteristic of the trap that this airframe can get to you: on base leg you reduce the speed but fail to increase the thrust levels back to reasonable levels.
Then on final turn, you pull to avoid sinking. However, because of the specific shape that the plane offers in this configuration, the AOA is difficult to see. In fact you are now at high alfa and by the time you realize it, it might be too late.

Here is a perfect example:

This was the 1/7th scale F-18F maiden a year ago.
Look at 2:20. I only saved the model from a crash landing in the sand thanks to the tremendous acceleration and high power rating of my P-200. Note the AOA of 45 degrees...
Same thing happens on the next landing try: look at 2:40 how the plane "sits" on the final turn. This time I had to land due to the fuel and I put the plane back on track into the runway at full power, reducing the engine only in the ground effect. The gear unlocked due to the poor retracts design.

Good save Oli, these types of scale models look like it is maybe difficult to relax sit back and enjoy?

Well, flying the 1/7th scale F-18F requires a good amount of experience since it is quite heavy and loaded. As you can see it goes very quickly into the high alfa mode and in that case needs a lot of thrust to get out ( I mean more than 200 N )...
Once you get used to it, you can kind of relax a bit. But still, the approach phase has to be well planned. The plane is fast and needs some degree of precision. Especially with cross wind:

The first landing on this video was a bit too fast at 110 km/h and the aircraft bounced.
The second one was good on speed ( on the highs at 105 km/h but this is required with cross wind )
On a calm day, the bug will land at 95 km/h. So there is a 10 km/h margin between "on speed" and "too fast".

This 1/7 scale version is a sweet flying one, I have considered using a 36lbs engine in one of this, but it seems that the right engine for it is a P200. Nice video by the way!


Enrique

Thank you Enrique.
Yes it is a nice bird, and what a presence in the air. You can be sure that when the P-200 starts, everyone else stops flying...
