Trumpeter liberty ship
« on: November 16, 2015, 12:17:56 pm »

Has anyone RC one of these kits, if so how was it to do the conversion,  and what was it like to sail.  The hull does look big enough?

I looked at it - at 1/350 it's 38.5cm x 4.9 cm with a 2.5cm draught - very small and tricky to get it all in without it sitting very low in the water - probably only good for swimming pools.
I went bigger and bought 1/96 - nice and easy to fit anything inside.  :-))

There is a 1/250 scale card model available if you want to scan the sheets and get them printed onto styrene sheets at a sign-makers - not a cheap solution, but waterproof and  a useful size of 53x6.9x3.4cm

Hi Plastic.  That's all I want it for, something to float in my pool, I was thinking along the lines micro servo, 4-6v motor, keep it small and light :-)) .
If it works I may build a few more different ships about the same scale, just for the pool {-) {-) [size=78%] [/size]

I've seen it done with a very thin, flat 6v battery glued into the bottom as ballast and power with a micro servo, micro rx and speed controller. There are lots of battery powered 30cm battleship plastic models on ebay for little money where you can rob the prop & shaft & coupling but the motors are normally 1.5 or 3v with AA batteries so you'll need a different motor - plenty on ebay for 99p from China

My costing would be kit + 20 radio, 5 speed controller, 5 sacrificial model for shaft etc., 1 motor from China & 10 for best-shaped, highest capacity battery.  :-))

Check out some of the indoor flying sets. You can get very lightweight receivers and servos powered by a single cell LiPo. The receivers often have an esc on board for a small brushed motor. The receivers are normally Spectrum DSM2 compatible.

I would suggest considering the Deltang DSM2 Rx 60 range of receivers with built in ESC(s) for micro work, especially if you already have a DSM2 Tx.  I use Micron to supply these fully configured to my requirements and can recommend them strongly:

I'm not sure you need to go to these extremes - the tiny 2.4GHz rx on cheap 2-channel radio sets weigh next to nothing and a the same goes for the cheap Chinese ESC from Ebay - the biggest/heaviest thing by miles will be the battery, motor and wiring so I'd save the money on radio parts and look at the battery shape & capacity to get the C of G as low as possible.

It can all be so low cost that I'd be tempted to do a 'fit and forget' installation with a on/off switch & charging socket in the highest point of the superstructure and seal everything else up for maximum waterproofing.

http://deansmarine.co.uk/shop/product_info.php/cPath/5_29/products_id/2726 is the original set which is forwards only and best for a high speed model such as the Airfix RAF launch or the Vosper MTB.

They announced the Microgear 2 set with astern as well here on  MBM in 2013 but no sign of it now that I can find on the DM website:

Thanks for that, but the price and postage will make it unaffordable for a rather cheap model. I might go the cheap toy root, that way you get it all TX and all the running gear,  it's only for the pool %)
