just got this a pressie for my birthday!

Very nice quality and good value too. Sadly I had hoped to use my existing lipos, but they don't fit, so looks like new ones are needed!

Should be in the 45-55 Mph range depending on the battery spec.

As mentioned I have ordered some new paired sets, but lest wait to see what they perform like.

Biggest issue has been trying to find some 3s 5000 mah, times two that makes a 6 s pack, that have EC5 connectors on them to handle the up to 120 amps draw!

I could,have made up some converters from my existing 5000 packs with Ec3 connectors, but I am concerned with the cure t on the ec3 connector.

I suspect the biggest issue will be somewhere big enough to really allow it to peak out, without it being too choppy, as I don't think that a 29 inch catamaran will like water with any chop on it!

Try this place for batteries if you are struggling. We use them for work and they are very helpful.

Nice boat. I've got a proboat mystic 29. I run it on 4s and a different prop. I've never managed to tune it properly, the nose is always bouncing along. I've tried shifting the weight about but nothing?! Any tips?

Not had chance to get mine on the water as yet james, waiting on delivery of the new batteries plus a few other bits to finch her off.

As far as trimming is concerned a lot of it is down to the angle of the prop mount on the rear out drive.

People assume that by moving the batteries fore and aft you will change the c of g, ( which you do of course ) but it does not always stop the porpoise effect.

This is due to the thrust angle of the prop, Wuxi can be adjusted. I a told there is not quite enough adjustment on our boats, but this can be changed by enlarging the hole.

Also you can blueprint the hull, but this seems pretty extreme to me.

There are lots of hints and tips here:-

I am just off to dig mine out of the barn, but mine is somewhat less efficient, does the same speed but is 5.7 V8 petrol powered hehe

Nice toy!

I've adjusted the prop but now you say there may not be enough adjustment this could be the case. I will have to have another fettle with it this summer. I could imagine the blue printing would make a difference to the performance but I'm happy as it is.

I like the crazy boat, especially once I'd noticed those tubes.

looks like it would be fun to race against my miss llumar as it looks a similar scale to my smaller 1/12 scale, although mines been modified so the rear wing is servo controlled to give it a bit more adjustment on the water.
i don't have any decent photos of it to give it scale but here's a few i grabbed off the net:

That looks ace!

What engine combo is in that?

IIRC it came with a dynamite .15, i'll have to go and get it out to double check what's in it now as i've not run it for about a year! Although i'm fairly sure it's now got an OS marine 21 in it, probably a bit too much but to be honest i've never managed to top it out and now that it's got a new metal prop profiled to the engine it's pretty insane.

Looks. Like nice, which Hull is that?

Also when it comes to twin motor set ups, how do you get them to both run at the same speed, to give equilateral thrust?

Its a HobbyKing Osprey - Hull only (1075mm) and its got two of these: https://www.hobbyking.com/hobbyking/store/uh_viewI... AquaStar 3974-2200KV Water Cooled Brushless (which will take 5S each).

Not run it in anger yet as the waterproof ESC are not waterproof and the damn thing is getting water in somehow - last thing I want is a lipo fire in the middle of the river.

Re balancing it - not quite figured that out other than planning to use the rudder!

A little test in the pond (needs a lake/river) https://www.youtube.com/watch?v=bOaVHlYEdqw

I'd have thought a heli giro would keep it straight.
