David, What about wing area, It should be the same for Empty weight and fully laden. Looks like another typo. wink 2

David, Was the refuelling probe on XJ823 removed for the Falklands War? I understand the RAF went around to collect the probes then, but it was never returned afterwards?

In April 1997 it received maritime radar reconnaissance modifications (MMR) and a gloss paint finish and served with No 27 Squadron. The bulge on the nose is part of that. It is assumed the probe was removed at that time.

David Mellor and I are building the South Herts Model together. We also both have the Mark Kettle Vulcan. I have the Tony Nijhuis 48" Vulcan converted to PSS.

I am a bit of a nut about the Vulcan.

Here is a picture of my TN Vulcan with XJ 823.

Ooops XJ 823 was converted in 1977 not 1997.

Sorry to correct you Alan but the bulge on the nose is the terrain following radar that was fitted to the Vulcan fleet after the mission profiles went low level. It was not a automatic system as fitted to the F111 but it gave the crew a warning of high ground ahead. The re-fuelling probes were removed from retired Vulcans during the Falklands war to fit onto Nimrods, Hercs etc. Max aircraft TO weight was 204,000lbs with the engines turned up to 103%. Spent 15 years working on Vulcans so a bit of a nut myself.

Having seen XH558 today, I'm even more inspired to build a Vulcan. Looking forward to the 78" version being released!

I will second that Chris. I am really interested in the 78" version. I guess Tony is pretty busy getting this year's special ready, but I'd love to hear how things are progressing

UPDATE

Well its almost 11 months to the day I repackaged the Mk1 prototype, its taken a good six months to redesign the model then rebuild to this standard below

img_4229.jpg

I decided to glass cloth the model and give it a light dusting of primer ready for the test flight today

This Mk2 version used all the avionics and fan units from the Mk1. The AUW was 9.14kg which is a shade over 20lbs. I was hoping to keep the model under 9kg so was a little concerned that the old 5-bladed Lander fans would struggle, even though the output thrust of each fan is 4kg.

I used a separate 3850 mah 10S NanoTec pack from Hobbyking to power each motor with two 100amp controllers. Using this setup on full power would only give about 2 1/2 mins tops so another worry was duration on this model.

To make the mixing easier, I used and igyro 3e from Powerbox

So writhing this now, i can report the model flew beautifully and the igyro made such a great difference i can thoroughly recommend this device.....

The first flight lasted 3min 20sec and scale flying was achieved at half stick position.....so much for being worried! The packs were charged a few days before this flight so when recharged I had expected the packs to be exhausted!....well on recharge, I could only get 1000ma into the cells so amazingly not even a third of the capacity had been used. The second flight was 4min 30sec and on recharging the cells amazingly I could only get 1100ma into the cells. I guess the extra min was a function of a freshly charged pack.

So based on this we are potentially looking at an 8min flight times on scale flying with a few vulcan climb outs thrown in for good luck....During the second flight i did apply full throttle, put the nose up and she climbed away at 60deg with no problem....

So yesterday I had almost convinced myself this model was going to have power and duration problem but today I couldn't have been more wrong......so still learning!!!

....I think this model may be the winner out of the three versions.yes

I was on the flight line with Tony during the maiden .It was absolutely brilliant ,I saw a full size flying over Stone henge in the early 60's and Tony's model brought back memory's of this ,stable at scale speed and rock solid in turns The second flight was even better .This model is a winner
