The 95 refers to it's length - 95 cms. So a class of it's own.

"Don't you just love speculation"
I rigged my DF65 with the A and B rigs this afternoon and after looking at the aspect ratios I think the rig on the "95" looks like a B rig.

And so the speculation continues - don't you just love it!!?

I suspect that the rig shown will be the A rig. The ability to carry a tall rig requires a heavy ballast. If the ballast is less, then the rig has to match or it will become overpowered very quickly if the wind increases. A heavy ballast also requires a stiffer fin or it will flex.

The other reason is the stiffness of the mast tube. If that mast is the same material as the DF65 it would be too flexible if the length is increased. Switching to the masthead jib, rather than the fractional rig (as used in the DF65) also help keep the mast from over bending.

You do have a point John!
No shrouds and a masthead jib means a shorter rig.
Less ballast = lighter boat = decent light air performance (acceleration).

This boat certainly belongs in a class of it's own.

....let the speculation (building interest) continue....

OK, time to end some of the speculation.

Congratulations John & Scratchy, you've just about nailed the concept of the DragonFlite95. It's a lightweight (2Kg all-up sailing weight) boat that relies on a long waterline length for it's performance. The keel bulb will weigh around 900g (depending on the final weight of the production fin), so, clearly it can't have a high aspect rig in anything but the lightest conditions. The profile of the A rig has changed from the photo shown earlier in this thread, but the area remains the same.

Joysway expect to complete the first prototypes by the end of July and they will be shipped to us for final rig development and testing. They have invested significantly in the quality of tooling used in the production of the DF95 and from what we've seen so far it looks to be paying off. We'll post photos and video of the prototypes when the development work is finished. The deck design has moved on significantly from what you might already have seen on the early prototypes, I promise you it's looking good!

We don't want to make any claims about it's performance at this stage as we only had limited time to sail the last prototype before handing it over to Joysway. All I will say is that we came away with a big smile after sailing it and can't wait to work on the rigs with the production hulls. Once you understand the concept of the design the reason for the low aspect, masthead rigs starts to make sense. It also has the huge benefit of being able to be packed away into an easily transportable package - a huge factor if you're considering attending flyaway events.

Expect the boat to be totally race orientated, no lightning flashes or dragons on the sails, just good quality Mylar sails with loads of room for large sail numbers. More information about setup and tuning will be supplied with the boat.

I could go on and on about the detail of the boat, but let's wait until we get our hands on it and we can show you what you're actually going to get. I'll gladly answer questions but some things will have to remain under wraps until production ready, don't want to make any false claims or mislead anyone. As Scratchy says... "....let the speculation (building interest) continue...."

John,
Thanks for the update. There is huge interest in the boat here downunder.
John T.

P.S When can I get my "Graphite" A, B and C suits for it!

The boat should be available around the end of the year and we'll get the class rules published before then so sailmakers can be prepared.

Thanks John. Looks like it will be a Christmas present rather than a 73rd birthday present in October!

I wonder if it might not be helpful to circulate a draft of the sail specification for comments among the sail makers. Our experience could contribute to an easily measured, appropriately sized and shaped sail plan.

John, I understand development continues, but would you mind sharing what the "Sticky Note" on the wall said about target cost, please ?

Thanks, Dick

The final cost is yet to be fixed, but expect it to be around double the DF65, still spectacular value when compared to similar sized racing boats.

Rod, thanks for your suggestion but you really need to sail the actual boat to fine tune the rig plans. Please be assured that we'll give enough influential people the chance to pass comment. I am a sailmaker and will give others the chance to try it out before pressing the 'go' button.

Moving forward, can we expect to have inventory here in the States? At 37.4" could be a tad expensive to ship single units to the "Colonies".

Congrats on another exciting new boat to stimulate folks to get into RC sailing!

You need to push Atomik, or whoever is distributing them, to get an order in to Joysway early to ensure you have them as soon as possible.
