Hydro marine "dr super evil ii " rigger

[kingwrench]

Started assembling the Dr Super Evil II. One bad looking machine. I have fabed and installed a carbon support for the strut and stuffing tube, fabbed a motor mount, and started locating the motor and getting it all aligned. 2012-10-04 21.18.15.jpg2012-10-04 21.18.26.jpg2012-10-04 21.18.45.jpg2012-10-04 21.19.02.jpg2012-10-04 21.19.16.jpg

What is your set-up and what is you expectations?

[kingwrench]

installing a neu 1527 .5y 2500kv, on 6s. This is my first rigger. Guess my expectations right now I hope it floats.

So this is a SAW only boat at 72,000 rpm? Motor may not live too long.

[kingwrench]

jcald, I never stated 72000 rpm, running 6s should give 55000 rpm, below the 60k motor limit. With the prop load I hope to see 37-40K rpm. These motors will run all day on 4s, and for a saw boat making two mabe three passes on 6s I will be ok, Not like I am the first one doing this. Granted its hard on the equipment, If you want to go fast you have to lean on her.

The motor will be fine for SAW use. I ran one on 6s repeatedly at SAW trials and it fared just fine. With a 250 amp average load it should pull around 42,000 rpm and give speeds well over 100 mph reliably.

A tip to prevent the loss of the rigger after a crash - run a wire fishing cable through each sponson boom, anchored firmly to each sponson. That way when the sponsons tear off in a crash - and they probably will - they will stay with the hull and supply flotation.

I would have more reservations about the hull than the motor to be honest, they have quite a lot of lift and are built very light, both in order to get good speeds round the Naviga oval whilst retaining 5 minute run times on our restricted battery weights. It is not designed for the speeds that motor is capable of pushing it, I can't see it not blowing over a few times on the way to a sorted setup, and I can't see the hull surviving a 100mph blowover intact either so make sure you fill all available spaces with glued in buoyancy so you get the bits back when the booms tear out and it fills up with water, I could be wrong but I think the sponsons are hollow moulded, i would give them a squeeze to check that, and if they are drill a couple of holes and fill them with foam so they remain buoyant when the boom tubes rip out.

Sorry for pissing on your fireworks, and I hope I am wrong.

Great idea with the fishing string thru the sponson, Could be quite a task fishing it thru the boat, but great idea . Thanks

I had the same impression of a hollow sponson, I was going to drill a fill and vent hole and faom them up. Hopefully get my set-up done quickly!!!

Any progress?

[SweetAccord]

I knew you were going to get something fast after you saw that one rigger. Nice! I wish to see how it comes together for you and how it runs.

In my testing, I have prefered the 15271D over the 0.5Y. The 0.5Y seems very inefficient especially at partial throttle which is hard on controllers.

Its Made by Hydro Marine out of Germany, I was going to order mine out of Germany, but found out Chris Fine, Of Fine Design Boats carries them in stock, I spoke with Chris seems like a really good guy made me a great deal and had the boat in several days. here is his link http://www.finedesignrc.com/

Who sells this Rigger?
TIA

[kingwrench]

Good info, Little late for me to change, getting that motor in there with the speed controller was quite a feat for a guy that has size 14 ring finger, and cant see close up any more, lol in the amount of time getting all the gear rigged in this hull I could have built 6 526cid promod race engines.
