I'll bee there around 2

Houston, we had some problems:  Today's float test showed some problems.

1) It sat nose down because of the heavier battery (1800 vs the old 1200).  I took out a 3/8" drill bit and drilled 4 holes in the shot ballast epoxied in the bow.  Photo 51 shows the 4 holes.  The two silver dots on the left are the rare earth magnets holding on the deck.  Photo 52 shows the shavings.
2) The prop shaft connector disintegrated (fuel tubing).  Put in new tubing and slipped 3 larger pieces of tubing over top to compress it. photo 53

The best news- not a drop of water inside.

Here are photos of the 28" sub.  Installed a new battery (1800 mah-2S), installed the old 72 meg radio* (channel 18), lubricated the moving parts (prop shaft, dive plane shaft, etc.).

Note in the photos:
- plexiglass top so I can see the parts.  The blue is the battery, it is a speed 400 motor, direct drive.  The esc is a waterproof one with forward and reverse.
- there are 2 pieces of blue paper shop towel beside the motor.  If it turns dark, I will know there has been a leak.  It also draws the water droplets away from the RC equipment.
- the plexiglass top is screwed down on the boat frame with 24 brass screws (they don't rust).  The brown underneath the plexiglass below the screws is silicone.  When the plexiglass is screwed down, the perimeter was coated in vaseline as a water proofer.  You can see the vaseline squeezed out into the RC compartment.
- the red connector coming out of the conning tower is the arming connector.  Once plugged in the system is live. The connector is attached with dental floss so it will not be lost.
- the sub dives when the forward dive planes are activated.  The rear dive planes are fixed at a negative angle.

How a successful RC dynamic diving sub works:
- it uses the smallest possible RC box volume to the total internal sub volume.
- the internal  area outside of the RC box is totally flooded.

This sub has been down 6 feet in a pool under full control.
Will test it tomorrow (Mother's Day) in the pool.
I cannot make it to Rogo tomorrow for reasons of self-preservation.

* 72 meg FM  has the deepest under water radio control over the old AM or new 2.4 gig.  Go FM or go home!

What a beautiful day. A bit chilly as shown by the coats.
Love the photo of Peter giving me the evil eye.

Photos taken by Andy Hoffer on Wednesday...its second flight.
He asked me to do a knife edge on one pass.  Sure Andy, it is not set up for that!  He did get the photo for the split second it was vertical (photo 74).

I will be there.

Want to try out my submarine.  Have been busy resurrecting it (new battery, radio and ESC).  The funny part will be showing up with a 72 meg radio.  It is well known in sub circles the only way to go is 72 meg.  It will allow control for much deeper dives.  This model has been down 6' in our pool without a problem and without behaving like a scale model of the Kursk.  Yes it came back up when asked to.

It is about 28" in length, a speed 400 brushed motor and is a dynamic diver (moving front vanes drive and hold it down).  While at rest the deck floats about 1/2" above the water.  It was published in the British RC model boat magazine about 15 years ago.  It is made out of wood (door skin) and glassed.

Other changes- spray paint the top a bright colour.  The current sub is flat black and will not be visible under water.  It will not go far or deep in TooGood Pond.

We had a terrific evening at the field.  Tried to do a check-out flight for a new member (Andy) who brought a 2.2-ish meter FMS Fox.  He was a Nitro Flyer years ago and wants to switch to electric.  It was a little windy for a hand-launch glider but we test flew it anyway for a trim flight.  The motor looked small, the battery looked small (1300-ish) but surprise- it launched fine, trimmed fine.  It ran out of juice a 100 feet too early....or the runway moved 100' upwind.  Sorry Andy.  My fault.  No damage.

Trimmed out his 1.3 meter P-51.  It flew fine, trimmed out fine and landed fine..eventually on the 3rd bounce.

On the Temac member side there were Guy, Mark, George, Glenn, Paul G. Paul S., Alex, Kenny, Andy (old), Andy (new), and a quick visit by Cadez.

The 3 of us flew our new Panthers together.

Parts came in last Saturday, fixed the landing gear and the only thing that was mildly annoying was the E clip. however the new ones don't come painted so that still has to be done.

the plane is thankfully flyable again

I will be there rain or shine at or about 13:00.
