Another teaser for a soon to be flown model from the English Electric stable - this time a Lightning F6 for 90mm EDF.
Same construction as the Canberra - CNC milled blue/green foam.

Even the wing section looks scale. Brilliant.

FINALLY... the weather and opportunity came along together for some in flight photos.

There was a hiccup with the launch technique caused by the underfins catching the bungee dolly and not letting go! Sorted by rmoving said underfins!

Anyway, I'm pleases to be able to report that the Lightning is another pussycat to fly, albeit a formidable one.

With a thrust/weight ratio of better than 1:1 she performs in prototypical fashion and is deceptively quick.

Now it's back to the workshop to add afterburner lights, carry out a little mod to correct the scale appearance of the cockpit area (needs moving forward slightly) and do a proper repair on the nose section following the launch issues.

Congrats on the maiden. Looks really good, especially the last pic. Is it an own design or kit?

Thanks Stuey. The last pic was taken while I was finding out if she'd go straight up from slow flight....She did! smiley

It's a prototype kit from Jim's Jets, milled from styrofoam (green stuff mainly) with laser cut wooden parts and vac formed canopy.

At 48" span and 67" long this one's a fairly impressive beasty!

What power setup do you have in there?

It's a Changesun 90mm 12 blade fan with an HET 700-68 1400kv motor on 2 x 4000 mAh 4s pack in series to give 29.6V nominal. The ESC is a Turnigy dlx 160A

The bottom line is almost 3000W and over 4kg of thrust static - rather more than adequate! Lol

The most spectacular of the jets Pete, if we all build one, we could do this

I anxiously await someone with more skill and bravery than me to slope one of these or the Canberra . Beautiful.

Didn't Matt Jones do a lightning for slope? His builds are awesome.

Thanks again for the kind words chaps. My second one is now progressing and will be flying by the time the clear skies and light, summer breezes arrive thinking

Rob, i'm sure that the Lightning will slope really well - she's certainly not heavily loaded, even with all the EDF gear inside. I'd hazard a guess that the flying weight without the power system would be below 2kg.

As for the Canberra.....PR9 pass

With all the wing area that the PR9 has, she can't fly anything but superbly!

The wing loading for my EDF version is a mere 16oz/sq ft

Great photo Denis. I've had some interesting info about it from a friend, Jim Gordon who kits the Lightning in this thread no less!

Anyway, this is what he has to say:

"Hi Pete
That is a very interesting photo as I think it is at Coltishall when an attempt was made to fly a big diamond 22 as its the only time I have ever seen that many taxying Lightnings. The photo is of the mk 1 and T4 line where pilots went first after fast jet training training on hunters after which they came to us on the T5 and T55 line for final conversion. One of the sorties the pilots on the T5 was to do a head on with another Lightning both in full reheat - frightening....If I am right the white building is the air electronics block. "

Fascinating stuff!

Pete, I've got a Cambrian Hunter kit and a HP Victor plan. . . . . Now you appear with these two . . . . . I've got a busy sloper building time ahead of me methinks.
