Thread: Hand Launching
20/11/2015 16:25:47

I once watched someone go out to the strip to hand launch his model only to hand launch his transmitter instead. Talk about laugh almost wet myself.

I know what you mean about the tight fit of the battery Trevor mine are quite tight which is good in a way it stops it moving around. My other Durafly model is the Sea Vixen which is a great flyer. It would be nice if Durafly bought out a Hawker Hunter I'm sure that would sell well.

Mark, have you measured the current on your 4s setup? As I said above, mine was pulling around 50A, which seemed a bit risky for a 45A rated esc. Hence, I'll try mine on 3s - I've set the cg with a small piece of lead at the front of the chin scoop.

I got as far as a take-off run and acceleration seemed good. Then a wheel dropped into a rut and the u/c came unglued. All fixed now and ready to try again, but the forecast is for a windy weekend so I'll probably wait a bit longer.

Hi Trevor

No not measured mine as yet but after flying on 4s the esc was hardly warm as was the lipo. On 4s anything over half throttle is way over scale speed but the extra grunt is on tap should you need it. Shame you had an issue but you will love it once you get it in the air, for a small model it has presence in the air.

It wouldn't balance without weight being added with the 3s Chris so used 4s and it balanced perfectly. Only need to use half throttle with 4s for scale flying and you get a good 7-8 minutes flying time. It flew very well on its maiden yesterday with only a click or two of trim needed for straight and level flight. Landings are good using the flaps but you have to keep a bit of speed up on the approach as with any warbird. The battery position is different as it needs to be slotted in at an angle and pushed into the back of the motor mount.

Not according to the charity. As well as engineering support being withdrawn - "Charity Vulcan to the Sky Trust, which runs the aircraft, said the plane was beyond its flying hours" from :​**LINK**

Edited By John F on 03/10/2015 18:53:43

I think they mean its gone beyond the hours of any other Vulcan. If it was out of hours it wouldn't be flying

As they say they are flying into the unknown but what the hour limit is now who knows.

Thread: Durafly P40N

Well the building of the P40 is very straight forward took about an hour or so to apply the decals and about the same to put together. The only thing I had to alter was the motor that was running backwards so it was just a case of swapping over two of the wires and all was well. Finished it off in the RAF scheme of 250 squadron Italy 1944 and all that's left to do is a bit of weathering.

558 is not beyond flying hours its the withdrawal of OEM support that's grounding the Vulcan.

Flying it Sunday morning before Gaydon then?

I might even take some superb pictures of it!!

If I get time Chris, I was thinking of asking the Hobbit with the big lens to take a few lol.

Going to try both 3s and 4s batteries and see how it goes.

I received my Durafly P40 today and I must say I'm impressed with the quality of the finish on the foam it is as smooth as a smooth thing and looks really good. I won't bore you with a build thread as it takes less than an hour to put together but I will post a couple of pictures once I've finished it.

Thread: New 78" Vulcan for twin 90mm DF

Keith

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.

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.

Fair enough Mark, you know your stuff.

Would the tank be used these days given the short flights?

Edited By ChrisB on 27/08/2015 22:08:26

We used to keep the wing tanks on 318 wet all the time to keep the system serviceable, they were used mainly for long transit flights but also if a venue were supplying free fuel they would be filled up for the return flight.

I've watched several of the poorly shot videos and the only thing I can see is a possible vortex coming somewhere from the aircraft. One video described it as fuel spray from the RH drop tank...highly unlikely and very faint.

Edited By ChrisB on 27/08/2015 21:28:30

Yeah i've seen that one Chris probably the tank venting which is quite normal.

27/08/2015 21:52:02

It was indeed a black day for British aviation and condolences to all those affected. I worked on Hunter WV318 for a couple of years when helping set up Delta jets at Kemble so know the workings of the aircraft quite well. To me after watching the numerous video's of the tragic event the aircraft seems to be low on energy and a little low at the top of the loop. I couldn't see or hear any evidence of an engine surge or a flame out as the engine can be heard running just before impact but it doesn't seem to have throttled up at the lower part of the loop which I thought it would have. We can all speculate until the cows come home but we will have to wait until the AAIB find out what went wrong.

Hi John

If I were you i'd remove the captive nuts and fit metric nuts and plastic bolts. I think 6mm should do it and you can get them off e-bay.

Thread: Next stop Elvington

A very good show today at least half of the huge crowd were there for just the Vulcan which helped fill the LMA'S coffers. Joined the LMA as well, getting out was a bit of a joke it was a free for all with no or little traffic management but that was purely down to the Vulcan effect and the numbers present . Apart from that well done the LMA.
