Re: Convair YF2Y-1 Sea Dart

Hi Dave, I don't look on here that much so I've only just seen your post. I believe the intention is the SeaDart will be completed although it's still in storage at the moment, we haven't done any physical work on it for around a year. I was hoping to get the go ahead to do some of the changes we me...

Re: Convair YF2Y-1 Sea Dart

Hi Dave,

We've been busy on other projects since the start of the year with very little done on the SeaDart since my last brief update. The plan is to dust things off and start work on the model next month in preparation for further testing.

Cheers, Alex

Re: Convair YF2Y-1 Sea Dart

Hi All, We're still here... plenty of work has been completed in ancipation of another test. We have completely re-designed the aft ski mechanism to allow the oleo extension to be controlled hydraulically and have damping through the use of an oil/air accumulator so the oleo can still fully retract ...

Re: Convair YF2Y-1 Sea Dart

Hi Dave, We are progressing and have just completed the second set of hydrodynamic tests last month. We have some challenges to overcome now we are exploring the higher speed elements on the water. We have made a video update detailing our progress and this will be uploaded this week. I will post th...

Re: Convair YF2Y-1 Sea Dart

Hi Dave,

We hope to do the next set of tests this summer, possibly July but this is yet to be confirmed.

Many thanks

Re: Convair YF2Y-1 Sea Dart

After many emails and messages asking for video we have finally put together some footage of our first test taken back in September 2020. We hope everyone is keeping safe and well and when movement restrictions are relaxed and it's sensible to do so we will be ready for the next set of tests culmina...

Re: Convair YF2Y-1 Sea Dart

With the knowledge that it’s now no longer taking on water at the rear, sitting at the correct water line and we can easily manage the aircraft in the shallows using waders we can move onto the RC boat bit of the test. With Dave in the follow boat along with three others either driving filming or ta...

Re: Convair YF2Y-1 Sea Dart

Hi Timothy, The petals would have closed a little with reheat, however the models static versions were well away from the efflux and with the engine runs at Buckminster without the shroud theses static elements were fine as they are mounted inside the the bypass. We will just remove them completely ...

Re: Convair YF2Y-1 Sea Dart

Hi Dave, If flown in the UK then it will need to go through the LMAs excellent over 20kg programme and all that entails. If operated abroad then we would need to have relevant permissions, initially we had intended to operate the first flights with a European Navy who have followed the project from ...

Re: Convair YF2Y-1 Sea Dart

I invited Dave Wilshere to come and take a look at the model and do some of the initial tests. I always value his input and I know he'll say exactly what he thinks good or bad which is what a project like this needs. I think he enjoyed getting everyone soaked during the engine runs. https://youtu.be...

Re: Convair YF2Y-1 Sea Dart

The first job was to get the model in the water and do a basic leak test along with checking the buoyancy. It needs to sit at the correct waterline or it will just look odd when compared to the real aircraft. Thankfully it worked out well… We did have a leak in the rear bulkhead where the rudder ser...

Re: Convair YF2Y-1 Sea Dart

Thanks guys... The model does get treated to a Nikon occasionally :) As you see it on the swing it was 91kgs so around 200lbs which is within the tolerance we expected. The moment I’ve been most looking forward to for years is getting the model in the water for the first time. There are so many poss...

Re: Convair YF2Y-1 Sea Dart

The other area for concern has been the CG, I had been keeping a basic weight and balance sheet incorporating all the components. This had been suggesting we were getting tail heavy and the model seemed in reality to be a little further aft than the calculations. I had failed to account fully for al...

Re: Convair YF2Y-1 Sea Dart

With the model ready for the initial engine runs we took it BMFA Buckminster. Phil and Graham from FighterAces came down to help as it needs three people to safely handle the model. Phil has been with us from the start of this project so I was pleased he got to see it run for the first time, I know ...

Re: Convair YF2Y-1 Sea Dart

An interesting aircraft for sure... I managed to finish the last of the installation on the electrics and engines before doing the first few engine runs. I always get excited seeing a model come alive for the first time. I was working insane hours to get it ready for testing so I didn’t take many pi...

Re: Convair YF2Y-1 Sea Dart

Apologies for not updating this sooner but over the next few weeks we should get to it all finished up to the current state of the model. With the beaching gear nearly completed we wanted to test fit it to the model to check it was fit for purpose before using it. A few small changes required but it...
