Hi mr. miyagi

I too have recently purchased an NQD Surfer Lisa and am also looking to hop this thing up.  Right out of the box, she doesn't work very well.  So maybe we can share some info here and hopefully others will join in and help us out.

I am planning to upgrade to a Brushless motor and to upgrade the radio as well.  Sorry, I can't answer your question about the Spectrum Radio you want to use. I am planning to use a standard 27Mhz AM car radio. However, I am looking to purchase a 4000kv 540 size brushless motor and a speed controller to match (today).  I am looking at the EZ-Run 8.5T/4000kv and an 11.1v Lipo battery pack.  This should give Lisa really good RPM.  I have read that the stock propeller should work ok but that you need to cut off the existing plastic motor to shaft coupler and replace it with a Graupner 3346 coupler.  I have also read that some lead should be added to the bilge so Lisa rights herself better and that you should fill the Lisa body with plumbers foam.   Please keep me posted on your findings and I shall do the same. 

The summer is here so I would like to get my Surfer going within the next two weeks.

Hi All

I took my Lisa Surfer apart last night to begin my hop-up.  Here is what I found and did: First, it appears that the new Lisa Surfer has a plastic steering fin.  It sounded to me like in the past, this fin was metal?. 

It also has a plastic box which held the original electrics (not sure if the older ones had this or not). I will continue to use this box to hold the new electrics. Also, I  painted all of my metal screws with clear rust proof acrylic paint and  coated the seals and the screws with a thin layer of Vaseline (this should help the seal be more air tight and keep the water off). 

Next, I found Lisa's head to be loose so I needed to glue this in place.  I am now in the process of replacing the servo with a stock full size servo from a 27Mhz car radio and receiver.  In order to install the new servo, I needed to cut off the thin plastic ridge servo holder where the front of the original servo sat because my new servo's servo arm was hitting this ridge.  I then inserted the new servo and glued it in place with 5 minute epoxy and replaced the plastic retaining bar back over this with the original screws.

Now on to the motor: The stock motor has a male hex coupler on the motor shaft end which then fits into a female hex adapter on the propeller shaft end.  I intend to replace this motor with a 540 size brushless and an 18-25 amp ESC. This morning I did some Googling and found some hex adapters which may work (in place of the Graupner 3346 mentioned in a previous thread).  Please, would someone look at these and see if they may work as a replacement.  I'll try to attach some pictures of my progress once I figure out how to do this.

Here is the link for the motor coupler.

Good morning from Spain.
I see that you practice a lot with rc surfer.me like information on where to buy rc surfer on the web. since it is a pleasure to greet the other side of the Atlantic.
thank for all

More mods:

Ok, the On/Off switch:  This is a very, very poor design! On my one and only outing with the stock Lisa surfer, the third wave, which knocked her over, also switched off the power switch.  This switch is a push button toggle (the worst possible design selection) and the wave pushed the switch to the off position.  Luckily I was in shallow water and did not need to go swimming in 55 degree water to get it.  So, I am going to bypass this switch all together in my modified version.

Motor Cooling Tubes:  next, I noticed that the water cooling tubes for the water intake and output ports are stretched to tight to the horizontal of the board which is pinching the tubes closed and I would presume impede cooling to the motor.  This is analogues to taking your garden hose and bending it - no water flow.  So, I wrapped the bottom portion of the tubes closest to the intake and output port holes with some electrical tape to give then more support so that they do not bend.  I also moved the hose clamps closer to the intake and output ports so that the tubes now have a more arched appearance.

Stay tuned for more later.

Do you think the weight can be added inside the board hull under the motor and not on the outside, underneath of the board? I am experimenting with this.

Try replacing all of the radio equipment with real RC grade proportional equipment. The stock equipment is very poor grade.

OK SURFN EXPERTS

I have been reading a lot of the posts on this thread and I need to know WHAT THE DEAL IS with the ESCs.  I see many posts where builders are using huge 60-100amp ESCs. 

I mostly fly planes which swing a 10x6 inch prop using brushless and never come close to 60 or 100amps.  Now this is my first boat so maybe I know nothing or am missing something here. But I know the prop is small and should draw little current (at least out of water). 

So, to test, I connected my new EZ-Run 540 brushless to my 18amp ESC and then connected this to an amp meter and measured the current.  To represent a load on the motor (prop in water)  I wore a glove and placed pressure on the motor shaft with my finger to the extent of almost stopping the motor at full throttle and never broke 5 amps. 

So, why the large large ESCs???????????
