A while ago (2005) I build this catamaran with 2 Phoenix 125 speed controlers and 2 Graupner inline 700m 24v. brushless motors.
The first time I went sailing, the 2x 16 NiMh cells melted!
So i parked the boat and recently i dusted the thing and decided to try again.
I bought 2 LiPo 6s 22.2v 5400Mah and tried my luck... and failed. Again.
The double speedcontrolers where fried while testing the motors and setup.
Now i need two new speed controlers who can stand the heat, abuse and the current.
Can anyone give mee advice?
I would like to enjoy this boat and stop putting money in this project.

Trying an other hobby is not the answer i expect :-)

Balancing DJI's Ronin-S (2 min 22 sec)

It occurred to me ...
That part of the problem lies with the way the pod is a attached to the boom .
3 screws holding it in place to a carbon plate ..
So a lot of force is applied to 3 very small places on launch ..

So before a problem arises , why not just epoxy the pod in place ?
Create a much larger area to distribute launch energy into !
Anyhow , that's what I have done with the Raven 990 ..
I fibreglass reinforced the pod , then glued it in ..
When the Epoxy dries , it should distribute load much more evenly over a much larger area .. ( + the fibreglass wont hurt too much - I hope )
That vertical fin is still weak as ! Next time it breaks , I will cut it out and rebuild it with more carbon reinforcing .

I have issued a product alert : ( Well - for what ever it's worth )

I removed the pod from my Raven 990 and it has a stress fracture @ the same location as my Mini DLG pro ( where it broke )

Major difference between cutting ply and ribs.

Ply requires tough love. Balsa ribs are like cutting through butter. Ply requires saving room on cuts so you can sand to the line. Balsa requires fluid smooth strokes right down the line. If balsa is poetry, ply is a tirade.

Used the drill bit in my hand drill. Blew smoke everywhere. Still looks like a badger made the inner circles.

HyperLow RS+ 6s (3 min 39 sec)




So i finally made the leap to 6s and was relatively surprised by both the flight times and power i was getting on this HyperLow RS+ build.
I have another RS+ that is running 4s lipos and it's an amazing quad,and i can honestly say it's probably the best flying quad i've ever flown in all my years of
flying quadcopters. I'm getting anywhere between 3-6 minutes of flight time on CNHL 1250mah 6S lipos and running Emax RSII 2306-1600kv motors.
I'm also running BetaFlight 4.0 with bidir/rpm filter and it's helped out alot,only time i really get propwash is when i forget to apply the throttle to harshly.
I've only been flying this build very rarely because i only have three 6s lipos so far. My next step to improving this

Here is the build list of the quad.

HyperLow RS+ (true x,and 15mm standoffs)
T-Motor 55A Pro
(3) Panosonic 1000uf capacitors
PiroFlip F4 (overclocked to 216mhz)
Emax RSII 2306-1600kv
Runcam Micro Eagle
TBS Nano Pro32
Lumenier AXII (micro)
Gemfan 5149
