Looking good!!! Keep up the good work

Hello everyone
I have a problem with the Jupiter! What weight should be done?
The mine is 1,823 KG.
Yesterday impossible to navigate, the front of the boat goes in the water too! It s sinking like a submarine of the engine running!
D after yourself what is the problem?
there is the same material that Lex ....
Thank you for your answers
See you soon
Michel

Hello Michel !

I have a "Wetback"wich has nearly the same size than a Jupiter.It weights 1650 grams ready to run.
You should try to change the center of gravity to the back.Also important is when starting :Full throttle and a bit of rudder to right side !Then it will not dive !

Ideal is 1500 - 1600 gram. Mine is about 1550. Have you put the batteries al the way back in the tray's? A 'heavy startoff' could be made by steering all the way to left or right and then hit the throttle full open. The hull makes an imediate banking corner and one sponson starts to plane. Then steer straight, still full throttle, and the other sponson schould folow.

Is the Outboard at zero tilt? Or even try tilting it up 1 or 2 degree to pull the bow out of the water.

I have to start my Jupiter with a burst of full throttle to get the bow up. If I try to start with half throttle or less I also get a submarine This seems to be tippical of a Jupiter.

200g is huge !!!!
Here is my setup for the electronics.

the material is:

I will try to change the center of gravity and to 1 ° or 2 ° downwards for the engine .But I could change the 200g too .I do not understand why auttant weight?
Thank you for your answers

Michel, where is your center of gravity right now? It MUST be behind the end of the sponsons. At least 2 cm behind the sponsons, but in this special case you can try even more, because of the S-shape of the Jupiter's bottom. In contrast to other tree pointers the original Jupiter planes a) on the sponson ends AND b) on the last inches of the rear bottom.

Jái nést pas vu le complet bateau

Une foto ,peut´etre ?Et nous pouvons aider In first,i think its overloaded

Uli

On the photo the battery's are in front of their compartments, put them all the way back. And let the pilot sit as far back as possible. As Jo said the center of gravity is not so critical with a Jupiter.

For the source of the extra weight; have you used a lot of epoxy, polyester or other sealing materials in the inside of the hull? From the identical setup the total weight should be near my boat i would guess.

Make the motor tilt 0 to 2 degree UP, not down! I run mine with zero tilt. Up tilt raises the nose when you apply thrust, down will push the nose deeper in the water. (witch you don't want .. )
