Greenman407 submarines

[greenman407]

I thought that I would reserve this spot and put all my subs info in it. The first one will be the first submarine that I built, The Albacore. Details Later.

Model Description: Subtek Albacore 1/60 scale.........Modified with a X-tail
Ballast System: D&E 3" WTC modified with a two motor bulkhead
Motors: Speed 400 7.2 volt
Receiver:Sombra SL-8
Pitch Control: Caswell/Mcleod ADF2
Servos: Hitec Minis
Battery: 7.2 Volt NIMH 4000 Mah with deans conn.
: 5 Amp Caswell
Failsafe: Sombra SL-8 Built in
Transmitter: Polk Tracker 3
Extra features: Subtek Electronic mixer, Duo-Prop independent drive via twin motors, Water proof on off switch at battery endcap
Speed control: Viper Marine 15
Coming modifications: increasing the size of the motor compartment to 3&1/2" to facilitate installation of 550 high torque motors. Also the use of a three cell LIPO. Addition of a sail with a movable rudder linked to a radio mix to coincide main rudder movements with sail rudder movements to prevent rollover during hard turns
History: Started out life in 2007 as a Subtek Kit. Using their T-Valve pump system, I was dis-satisfied with performance and reliability. Upgraded to the D&E Cylinder, it became more reliable. Got rid of the Hitec 6 radio system that proved completely unsatisfactory and went to Futaba 9 channel which also proved unreliable but was a better system,problems possibly due to some incompatibilities with extra components ie: Speed control, mixer, failsafe, BEC, or pitch control. Changed to Polk Tracker and it entered into a new phase of reliability. Replaced the Polk receiver with the Sombra SL-8 after the latter proved more capable. Spent much time fine tuning ballast tank control procedure for improved static diving and surfacing. Then converted Albacore to a Phase 4 configuration , including Dual counter rotating propellers and Modified sail shape. I hope to acquire a sail from Dave Merriman that has an operating sail rudder on it. Here is the link to the Builders Thread on it:http://forum.sub-driver.com/showthre...core-continued As of this time the Albacore has been updated with dual 550 motors in a 3&1/2" motor compartment while retaining the 3" Ballast and battery compartment. The APC4 has been moved into the battery compartment along with a 3s Lipo. The sail with integral rudder has also been installed. Testing to come.
Here is a link to a video I shot of her a number of years ago of the results of my efforts to get her gas ballast system to perform in more of a scale like manor.http://vimeo.com/10523913

Model Description: Rick Teskey 52" Seaview(8 Window)
Ballast System: D&E 3"WTC Mod. 2 has been modified with the motor compartment being increased to 3&1/2" in order to allow for larger motors to be installed. A home made motor shaft grease seal system keeps water from entering WTC thru motor shafts.
Motors:(2) Original Speed 400 motors have been removed in favor of "Team Brood" 540 hand wound motors of the 27 turn variety. These motors were chosen for there much higher power output vs. the standard 540 or 550 motors. Also they are built to operate on 12 volts and can withstand high heat.
Reciever: Sombra SL-8
Pitch Control: UPC installed within a forward mounted battery WTC
Servos: Hobbico CS35MG Minis
Battery: Onyx LIPO 3s 6400 Mah 25C 71 Wh Housed in a Caswell Battery WTC
BEC: Caswell 5 amp.
Failsafe: Sombra Labs SL-8 Built in, configured with Shadow Controller


: 4 blade Empellors with 1/8" diameter thrust bearings, Battery WTC, Modified control surface configuration to include stern planes
History: purchased her in 2008 and experimented with different componants until arrived at the present reliable configuration. Changed motors several times until discovering the 12 volt version of the Speed 400 and then finally the 540 motor configuration in a modified 3"/3&1/2"WTC. Thereafter trimming the 4 blade empellors down to two blade ones increased thrust and run time as well as motor life. However, since the addition of the new motors I have reverted to the 4 bladed empellors due to the power available. Thrust has been increased by a factor of 8. Made a aluminum motor mount and copper motor cooling sleeves, but this has been deleted. Polk Tracker radio increased reliability and decreased stress on operator. Much attention has been paid to eliminating APC jitters of the stern planes and propullsion planes. By installing the APC in the bow mounted battery WTC and taking extra steps to insulate from vibration and other factors, all jittering has been removed. Room for future expansion, including operating Sail Planes. Here is the link to the continuously updated Builders Thread on it. http://forum.sub-driver.com/showthread.php?763-Seaview

Excellent Mark, i love the counter rotating props, me love special mechanics

I just updated the info on the Albacore and the Seaview. I need to add the Oscar, type 23 and the Skipjack. Soon.

Scaleships oscar in 1/96

I think it was 2010 that I ordered an Oscar from Scaleships in the Ukraine. Here she is. Details to follow. Here is a link to the Builders Thread on it.

http://forum.sub-driver.com/showthread.php?1108-Oscar-Continued

Model Description: Russian Oscar Class guided missile nuclear submarine in 1/96 scale. Model manufactured by Scaleships in Ukraine
Ballast system: Caswell/Merriman Subdriver, 3&1/2' DIAMETER, TWO MOTOR OUTPUT
Motors: Two Caswell 550 12 volt motors
Receiver: Sombra 8 channel
Pitch control: UPC mounted inside battery WTC(shared with Seaview)
Servos: Futaba S3001 standard servos
Battery: 3 cell Lipo Onyx 6400 Mah 25c
Failsafe: built in failsafe in Sombra
Transmitter: Polk Tracker. I use this same radio for all my subs and a few other vehicles
Extra features: This model is equipped with the Caswell SNORT system. It also has powered bow planes.Counter-rotating Brass props, Equipped with a right and a left Raebesh 7 bladed propellers, 55mm diameter.These propellers provide substantially more thrust than the props that were included in the kit but not as scale looking. The kit supplied props were lost during its shakedown cruise.
Coming Modifications: A 4 point thruster maneuvering system using 4 brushless pumps with individual speed controls to reduce turning circle and to maneuver without using main drive. Will add a Caswell 5 amp BEC
History: Purchased in 2010. Took me two years to build due to factors beyond my control. It was my first underwater camera platform.

What a beauty, Mark.

(Tribute received and appreciated ... I'm enjoying one as I type this).

Revell 1/72 skipjack

Purchased from Caswell in 2013 and completed in that same year. Dynamite performer. Was test run and dialled in without paint. Paint job is 90% done as of Feb. 2015. More details to follow.
