Appreciate the link dubd. Incredible accomplishment. I have to admit Comp ARF are always pushing the limits of RC!

Sorry Jetjocks, do not want to hijack this threat - i will start a new threat on this incedent regarding hornet. Not saying that this is the cause. Anton and I have exactly the same thoughts on twins as David Gladwin. Being a full size pilot myself - if you have engine out on twin at V2 you bring her home fast - even land straight off runway. Heavy twins require greater skills and knowledge than singles.

But the trent nowadays is to put way too much thrust in rc jets with the thinking that if i loose an engine i can still fly. Wrong. You need opposite rudder or gyro programed throttle back and nurse her home. I normally keep straight never turn, climb to safe altitude, cut running engine and glide back safely just incase i want to get crazy and want to do a go a round.

I will update the manuals to include this vital info.

We at Skymaster have tested all skymaster twin jets with low thrust turbines. Even A10 we flew with 2 x 8 kg turbines. If one flame out - we land back safe even if 8kg full thrust. But some customers installed 21 kg turbines and then try to fly a10 on 1 engine at full thrust - impossible for a novice pilot.

Just some of my thoughts on twins....

Video of the CARF Sukhoi. I don't know how long I can hold off on ordering this plane!

No problem! The B2 looks awesome!

I don't buy that on the size factor and too much thrust casing the crash. This particular model has engines waaaay closer together than my F-14. Because like folks have stated mibo a-10 flies just fine single engine, while a SM will not end good. Gun already had a flame out on the maiden and it did not end like this. Just my two cents but I'm nobody.

A lot of fighter jets are designed to fly with one engine out of action, I believe even the A10 was designed with this in mind. How well they fly, how much power and rudder is required I cannot say. I remember when Australia was looking at buying its F111 replacement the F18 was promoted and accepted as being 2nd chance jet if one of the engines was lost. Airliners or even smaller civilian multi engine airframes with engines out on the wings definitely rely on the reduced power and plenty of opposite rudder for any hope of recovery a lot more so than twin engine aircraft with engines closer to the centreline.

Don't get me wrong, if one goes out I would not continue with the full flight and landing would be my priority.

NOPE! Full scale Multi engine jets certified under Part 25 (jets over 12,500 lbs) can fly straight with the remaining engines at full power! I think that Reynolds numbers come into play with smaller models and we get into directional stability problems. There is simply not enough rudder authority to overcome the asymmetric thrust.

I can say from experience that certain high thrust to weight aircraft are VERY difficult to get back on course if the correct rudder is not fed in promptly. Since we are not onboard, we are ALWAYS late to respond to an engine failure. The remedy in most cases is to reduce the thrust to regain directional control......it is not instinctive to do such.

The reference to multi engine civilian airliners and smaller civilian smaller multi engine airframes wasn't necessarily gospel for all aircraft. Prop aircraft are very critical on reducing power and rudder use. Put it this way...you loose No1 engine on a Hercules on takeoff and its pretty much accepted it will be a ditched landing.

Hard to see from the video but it seemed to be yawing hard left on the runway right up to rotation. What turbines were in it?

Assuming he had a functioning gyro onboard , it would have (should) have put in some rudder correction . That should at least slow down the ugliness till the pilot can add the necessary input.

David Gladwin

It's clear from some of these posts that some guys do not, and some do, understand the mechanics of asymmetric flight.

The comment on airliners requiring a thrust reduction in the event of an engine failure is entirely wrong. If conducting a takeoff at reduced thrust, ( a frequent procedure) all performance requirements can be, must be, met, and it is quite acceptable, perhaps desirable, to ADVANCE the live engine to FULL power. ( and. I speak as an ex Boeing training captain)

Rather than divert this Florida Jets thread perhaps it might be better to start another thread on the subject. A constructive and educated thread perhaps.


Anyone agree?

I think gunrad put twin k180s in it

You can Create a page under your account that will not show your information. I was thinking of doing it too for build threads " I was thinking of naming my page "JR's RC Builds" lol. Same goes for Jet events. The event owner can create a page under their account and allow other to post pictures of the event which in turn can be searchable via facebook or google.

Inexperience was not the problem, Kris is a very experienced and very good pilot, he has probably hundreds of flights and many MANY flights at big events so the environment and spectators don't intimidate him.

Poor decision making wasn't the problem, he made the best decision he could with the information he had at the time.

Ali had helped him with a bunch of trim, he got it what he felt was under control and decided to take a lap to get both the gear and his pulse rate down.

I was there, I saw it happen and I know him pretty well so I'm not second guessing and faced with the same situation I could only hope to have handled it half as well.

Well said. It's easy to arm chair quarterback these situations.

Anyone catch the big collision crash of the HAVOC and Hawk ?

BarracudaHockey

My Feedback: (11)

Sorta , I got a few shots but not the payday shot.

I have 12k photos to sort through and delete the crappy, out of focus and repetitive shots, when I'm done I should 30 or 40 to publish

did that happen today. I left yesterday about 3pm?

That Sukjoi is sick!

Yes indeed!

Yep, later in the afternoon.

Lukie's Havoc and that Saudi scheme Hawk. Sawed the wing off the Havoc, it hit in the grass down past Boli's tent, the Hawk hit out past the runway and went poof.

Ok that just sucks!!!

If I was going to buy a Sukhoi, I'd wait on this one...
