Just built Krick RO-Marin Neptun. First tug I’ve built, she came out okay, I think. 6volt system, MFA 2.5 geared motor, Graupner SXM switch controlling the lights, older Pixie brushed esc controlling water monitor pump. Old Futaba MC210 for motor esc, Frysky QX7 radio. This video was shot at Towne Lake, McKinney Texas. She well on her maiden, needs about 2-4 ounces ballast in the stern though.

I built this from scrap wood i had lying around i bought the tanks from china the motor is a 850 mfa with a speed controller powered by a 11.1v 5000 mah battery
still in progress 😉

This Aerokits "Sea Commander" was built C.1961 by my father with ED Mk4 diesel engine and his own scratch designed and built radio/receiver ( I have all his design documents). He raced it successfully in the early '60s but hadn't used it in years when I inherited it. Have now replaced the IC motor (mothballed carefully) with MFA Torpedo 500 but it runs a bit slowly ("river cruising" scale speed). Looking to obtain semi-planing but not racing speed.

The San Pedro is a North American Push Boat.

She weighs in at 21 lbs
L.O.A. is 30"
Beam is 12"
Draft is 3" 5/8"

Her Engine Room Consist of:

Two MFA 919D 540 Type Motors with Single Ratio Metal Gearbox 2.5:1 Reduction
Two Mtroniks Viper Marine PNP 15
One Action Electronics Throttle & Rudder Mixer
Two 6 Volt SLA Batteries in series
Running time is estimated at 2 hrs

Rebuilt TID from a Bring and Buy table.

MFA 800 12v , 55mm prop built to tow 😉

A few pics of my partly scratch build RTTL from Kitshack. Picked this up from Ebay as a first kit.
Has a few printed balsa hullparts but lots of templates to cut out. Plans also show lots of topside details.
Powered orignally by 2 MFA 500's and 2 7.2 NiMH with 35mm props, OK but run time poor.
Complete change, 2 400's and downsized to 25mm props, much better run time and good on the plane.
Next upgrade is to LiPo batteries.

Next build is likely to be an Aerokits Sea Hornet or Sea Breeze.

This 1/12 scale model is based on the Aerokits Solent Class lifeboat. Over the past 5 months it has been under going a major refit. I originally built the boat about 35 years ago and got the "bug" again last September. I've done the best I can to make a silk purse out of a sows ear.

Its powered by two MFA Torpedo 800 electric motors. power comes from two lead acid batteries, each rated at 12v 7Ah. Control is provided by two Mtroniks Tio ESC. The twin spade rudders are linked to one servo. Each ESC has its own receiver. I found that one receiver, using a Y lead, could not continuesly keep the two ESC supplied with a signal and they kept going into Failsafe mode alternately. I got round it by binding two receivers to the one transmitter. Within the engine compartment is an automatic bilge pump. Two probes detect if/when the water level rises to a certain amount in the bilge and activates the pump.

The model has working radar scanner , navigation lights, search light and blue flashing light.

Sea Queen aka MALLARD
I built it from a kit a few years back sold it then bought it back to do a refit & new paint job
MFA 850 torpedo Motor 3 blade brass prop it runs on a 12v Battery it is now with my nephews son in Northallerton

Another great MFA boat , never had one that didn't look good on the water . This is running original twin 850s but is soon to be dragged into the 21st century

My son's boat , started life leaking like a sieve and fitted with a brushed motor . The brushed motor did however serve the purpose of being a trainer for him to get used to the boat and controls . He now has a brushless inrunner water cooled and 3 cell lipo's giving great performance and duration . Home Surf is Needham Lake in Suffolk

This was a very beat up and plain model when I bought it , but has cleaned up well . Original Power was from a Torpedo 850 and heavy 12v 7Ah lead acid battery giving run times of around 20 minutes of plod along performance . Now however Boat is powered by Thumper motor and 4 cell Lipo's giving over an hour of entertainment . Cut's a fairly mean wake too . Needham lake in Suffolk is it's home surf 👍

My own design deep "V" hull with upper-works loosely to 1:15 scale replica of the Mitchell 31 boats previously used by various Hampshire constabularies in and around the Solent. The intention is to fit this model with a working, rotating, radar scanner using the servo motor and gearbox from an old video camera lens system; working lights including flashing blue police lights and a sound-alike "wee-wah" siren - just for the hell of it (and because I can)! Technical details: Hull length: 867mm. Construction: GRP layup with 1.5 and 3mm ply and balsa deck, cabin etc. Motor: MFA Torpedo 850. Propeller: X50mm plastic. Battery: 2 x three cell LiPo pack in parallel. Speed controller: Mtroniks Viper 25Amp. Radio: Hobby King 2.4GHz.
