hi guys
im new on this forum but old hat to boats
i am having a major nightmare with a magin one competion powerboat by robbe
i have built the boat as per instructions to the closest spec of dust and i cannot get the flood chamber to work.
the chamber is 110% watertight
the boat is spot on with everything by robbe
1 x magin one in yellow (£99.99) just for kit
1 x 700 inrunner brushless motor power set (£102.99)
1 x ROXXY BL-control 960-6 esc (£99.00)
2 x 11.1v 3250mah 3s lipos (27.99 ea)
1 x 2.4ghz 5 channel planet t5 transmitter and reciever (£49.99)
1 x lipo protector (£14.99)
yes i know the prices are dear but this is the prices the model shop near me charge.
anyway i took the boat out for its first run (fresh water medium size lake)-excellent top speed approx 3ft rooster tail out the back.
after about 10 mins the boat got attacked and damaged by a swan so had to abandon run and go home to repair it.
later same day after boat was repaired took it out.
whislt running boat in saltwater lake this time few runs back and forth including top speed i accidently piloted the boat to the right and it ended up upside down in the water.(wont be doing that again)
when i eventually managed to retrieve it after wadeing in up to my waist to get it, i found water inside the boat due to the tape i used to secure the top down allowed water in. the salt water had fried the esc,1 battery,and lipo protector.
i cannot get the flood chamber to work at all.the holes are of the correct size as per instructions (10mm) except for the one in the side of hull which is 6mm) and all in the correct place
can anyone help as to why the chamber doesnt work.
the boat has now been tested at home in the bath, and i still cant get it to work.
when placing the boat in the bath correct way up it sits as it should with everything in it.
then when you turn it upside down it stays upside down.
please please can any one help.
regards

well i am very dissapointed that no one wants to reply
84 peeps have read my post but no-one wants to give any suggestions or help
am i the only one who has built a MAGIN ONE by the terrible company ROBBE
well i wont need any help in future for this poor excuse for a powerboat as i have now thrown the hole thing on the bonfire and it is now a melted blob of yellow and black plastic.
mind you the batteries went with a very big bang.
i didnt even keep the motor as like most RC stuff these days it all seams very poor especially if it is made by R****
i will be buying a different make in future.
thanks for no help guys.

Perhaps a photo of the flood chamber in question, is necessary.

Not know what your boat is, or how the flood chamber is placed, open to the sea, or vented, I
can not begin to comment on what the problem may be. I am sure this is the same difficulty that
others are experiencing, and what may be causing them to hold back comments, till more information, or
someone familiar with your boat, and it's design, can offer insight into the problem.

Sorry,
But I just don't know the model.

The Robbe Magin One is a semi scale offshore racer powered by 12 cells and a 700 size motor.  It has a couple of interesting features including a self righting capability and a emergency power cutoff.  The self righting capability is achieved by using a free flooding tank.  This tank takes on water while the boat is upside down and causes the boat to roll back right side up.  The emergency power cutoff is accomplished by installing a removable wire loop in the main power circuit.  The loop is installed right on top of the deck so it is easy to get to.

I found this info quite quickly from Google.

You will find that a lot of the items marketed under the name 'Robbe' are not actually made by that company. I'm almost certain that the ARTF models are, like most other ones, made in China. The Quality Control of goods coming from there can be questionnable (to say the least), so don't make the mistake of thinking that avoiding Robbe goods will mean that you don't encounter shoddy goods again. Other Robbe items are first-class e.g. their fittings, radio sets and some kits.

I've never heard of the Magin One either, but I did find it when I Googled it. Not my sort of model, I'm afraid.

Great, so how does the flood chamber take on water, and how is it vented and drained?

Seems like a question for "Pompled", that races boats with flood chambers regularly...

Umi,
It free floods when the boat is inverted.
This moves the centre of gravity and it turns upright where it self drains. I think.

well hello to one and all
i appologise for the previous post but have had many probs with the afforementioned boat.
the flood chamber is built in the following way to make it work.
a watertight vessel that fits inside the boat is sealed by placing a flat piece of material pre cut to the chamber.
this is then fitted to the left inside the boat and again sealed to the boat e.g. underside of topdeck,inside of side hull and to base of hull inside.
once dry you have to drill 6 x 10mm holes along the length of the top deck to macthing the length of the flood chamber.
in the side of the hull where the flood chamber is situated but only at the front a 6mm hole is drilled.
then at the stern of the boat at the top again only to flood chamber we drill 2 x 10mm holes,below this we cut out a very large hole to the shape of the inside of the flood chamber only.
the idea of all the holes is as follows.
the rear large entry allows water in when the boat is the right way up to get the boat to settle at a prediterminned position, as the boat starts to move forward from its rest position the water is forced out when air enters the top deck holes and this brings the boat up on to its correct plane for speed.
if the boat should then capsize the flood chamber should do the following.
the 10mm holes allow water intake rapidly as does the large cut out at the back this the should make the boat heavy on this side which then should make the boat start to right itself.once there is enough water in the flood chamber the boat should then continue to right itself until it is the correct way up
unfortunatley mine does not do this .
i have spoken to a chap at last who actually built one and the only thing he didnt do to his was the 2 x 10mm holes in the rear. h
he has had no problems with his flood chamber but cannot suggest why mine deosnt work.
will try and post some photos soon
