Plastic Conversion

Just started converting two 1/72 plastic models (MiniHobby) Vosper 15" and the Chinese patrol boat 19". I just made two stuffing boxes and slid them in for fit. Will epoxy them in next. Thinking of using either speed 400 or 280 motors. Will post pics if anyone wants to see them. These are my first attempts at plastic conversion. Have built two vac-u-tugs and numerous cars and a few planes. the conversion seems to be going well.

You betcha! Did you see Pat Tritle's IMEX Bahrain conversion thread, I think it is about 16" long.

2 x 280's sounds more than enough for scale like performance. Even so, I think it's going to be a tight fit. It might be worth thinking of a gearbox, as you won't have much choice of props on direct drive.

I will post pics soon, will try to get them up later tonight.
I think I will be using a single speed 400 in both, haven't decided if Im going to use my 6v or7.2v motors. Just epoxied the stuffing boxes in today.

Nice R/C conversions...I'm enjoying your build pics.

If you don't mind, please explain what the electronics are in your pics...you know...brand and model # info.

I'm doing a 1/72 Flower Class conversion at the moment...got a lot more room to work w/ than you do.

I've got a Tamiya Vosper in the stash...awesome detail...may give it try one day.

Best of Luck w/ your builds,

Please explain, for the less electronically gifted among us...not sure how a servo becomes propulsion for r/c boat?

If you look down the list of topics in the "Past reviews and builds" thread pinned to the top of the scale forum you will find links to how servos can be use as speed controls. Patmat's is one of the linked articles I think.
However these are for slower speed boats, and not for fast, or high amp draw motors.

Electrics

The items I have for the Vosper are a speed 400 7.2V motor a standard Cirrus Servo, a blubird mini/micro servo (haven't decided which one I am going to use, a BRP battery pack (from my old Buds 1/18th racing cars) and an old Novak forward only esc. The Chinese Patrol boat has a speed 400 6.0V (may switch the two) a standard Cirrus servo, Brp Batt pack and a Traxxas XL-1 esc. I have a couple of old AM futaba 2 channel radios w/receivers. Have an FM setup with a Hitec three channel radio in My Vac-U-Tugs. Don't know which radios will end up in which boats. As you can see most of the stuff is older stuff (some stuff as old as 13yrs and still working)that I had on hand from the years of racing cars. Also have a couple small GWS esc's for my blue foam planes(inexpensive) that I can also use, depending on the room available.

What about weight? Isn't that equipment maybe a bit heavy for such small hulls?

weight

I am hoping to use the equipment as the weight so I don't need to add bb's or lead. I can use the lighter esc's if needed and the batts are AA size not sub c, so they aren't too bad. The Chinese patrol boat is 19" long 4"beam, the Vosper is 15.5"long and little over 3"beam. I haven't tested the boat weight in water, but that will be soon. All I can do is hope it is not to heavy. Will let you know after I set the boat in water with gear laying inside.
