2600KV motor will push that model more than plenty quick.

I can't stress enough on tuning the prop, make sure your shaft alignment is perfect, and thoroughly bonded into the hull with two part epoxy.

Should be quick when it goes, so spend time on your centre of mass C/G otherwise it will be more realistic than you want... pricey kit to end up on the bottom of a lake.

Hi Richie,
I've spent all day modifying the hull for the flex drive & the motor mount. I've measured it so many times I'm on the verge of blindness. Hopefully I'll get it all epoxied up before I go to bed tonight so it will be good to carry on with in the morning.
Where do I need the c of g to be? I'm guessing just behind the rear outrigger.
Now to consult the YouTube bible to learn prop balancing.
Cheers

Ian, did you get my PM?
Cheers

Videos on YouTube watched & a magnetic prop balancer ordered off eBay, I've also managed to get a load of epoxy around where the shaft goes through the transom & forward 50mm over a brace across the width of the planing wedge. The only way to get this bugger out now would be with a hammer & a blow torch.

That's a one for Mike, mind I would tweak the position as I don't think the C/G will scale plus your angle of thrust may not be the same as the jet turbine ;) ;)

You will need a small amount of tail weight I would think, but not too much otherwise "I've gone!"

I don't want to say "I've gone" ever, I'm completely open to advice.
Anyway, I've made what will eventually be a waterproof box for the servo, I'm just about to put the lid on, just need to work out how to make the end so I can open & close it but still be watertight.

When I suss it I'll do the same for the receiver.

Silicone sealer it together, at least you can cut it open easily

Anyone know what this is?
I spotted it hidden away at the back of the Campbell collection at the Lakeland motor museum..

If that silver band across the pointy end represents a windscreen, then that would give some idea of scale.

I've got to admit I thought Ekranoplan or Caspian Sea monster when I saw it, the thought of adjusting the canards to get the desired front end lift I find horrifying...

Hi all,
After a lot of trawling the interweb I think I've found the source of the K7 Nexus plans, I've ordered a set & I'll leave feedback when they arrive..
