RC Helicopter flying, RC Cars and RC boating

Made for other people and me to track what I am doing when with my remote controlled units. It started out with helicopters. Hence the name.

If only one of my units is of interest, this unit can be clicked on the right and only posts regarding that unit shows up.

This blog is open for comments so feel free to leave a comment.

First test completed :)

Tamiya VOSPER MTBPosted by xilsoe Mar 15, 2009 17:08:08
On Friday 6. of March I tried the VOSPER in water equiped with the RC gear for the first time. That was a huge success. It was fast and really manoeuvrablesmiley At that test I was using a 2s LiPo and the 20mm propeller. I hadn't put the deck on for the test.

At the test I determined that more weight could be added at the back of the boat, so I decided to go for a two battery solution, where one is placed at the front and another one in the back. At the same I decided to go for 3s LiPo batteries as I would like the boat to go faster. So I found two 600mAh batteries that are about the same size as the 2s LiPo I tested with the first time.

If the boat becomes too heavy it is posible to use lower capacity LiPo batteries.

I suppose there has been a lot done since the previous post. I made the motor mount and mounted the drive shaft. I also mounted the receiver in a fixed, but removable manor.

One of my friend at work had an accident with his 1/18 buggy, where water had come into the ESC. The result was that the car went full ahead and he ended up crashing and breaking lots of parts. I don't want this to happen in my boat, so I have been waterproofing the receiver and the ESC as my boat is probably subjected to much more water than his car was.

I have also been painting the red color on the buttom of the hull. Then I put it on the supplied boat stand, and it was immediately scratched smiley I guess one of the next things to do is to make a decent boat stand for this boat. Another thing is definitely to try it out with the 3s LiPos.

I also spent some time soldering so I can connect the two batteries in parallel in the boat and charge them in serial with my charger. When I decided to have two batteries in the boat, I also decided not to use 2mm gold banana connectors for battery connectors. Instead I use Micro T connectors. The reason for this is that when only one battery is connected, two powered male connectors would be exposed, leading to an increased risk of short circuit smiley

I hope to make more updates in the near future.
