|Buz. I think this of sufficient size for a trio of speed 400`s, but perhaps a set of speed 280, or speed 280 race from Graupner might be a good fit, they are indeed feisty littly units and spin a 25mm prop with gusto...I am guessing the props on the schnell wont be any larger? As for rudders, i think that an increase in size over the kit ones is definitely warranted, i have seen similar pt boat conversions and the scale size rudders have been far too small on the pond (my experience)for good for manouverability. And after all you can always make them a bit smaller later on. Ashley|

|Buz. Shaft length depends on where you put the motors, the boat will be very light, so I might suggest test floating the hull with some motors, gear and battery in to see where the stuff should go for correct weight distribution, also bearing in mind the access arrangements, ie what hatches you will have to get to the stuff. Access is required for motor/coupling and rudder fiddling, but the receiver and battery can be slid into place somewhere. 4mm shafts may be a bit heavy for the boat so 3mm or even 2mm shafts might be needed, and I recon 3x Graupner speed 280 race motors and 3x 25mm brass props would provide adequate go, or speed 400s .depends on the weight, speed 280s are very much smaller than speed 400`s. Must be someone out there who has converted one by now??|

Buzzer, There are shed loads of information on this build on the Model Boat Mayhem forum, with lots of pictures and links, some of them to sites outside the UK and not in English but the pictures are very good. I'm trawling through them all at the moment before starting my own build.

|Buz, there is a man on our pond wot is building an E-boot, and I am not sure if it is the plastic one, it is about the right size, but he has some tiny brushless motors (2) in it and some equally tiny props and, boy, does it go! does it make a very high pitched screaming sound as it takes off? does it look more like a hydro than a torpedo boat?? does it strip the blades off props very easily if it encounters an underwater object and then steer only in circles??? yes to all these. He has 2mm shafts and so is having to get some brass props made. The lesson to be learned here?? its fast, oh yes, very fast. Go brushless.Ashley|

SHG Model Supplies can supply a bespoke set of shafts/motors/props etc. specifically for converting this kit. Dave Abbott is using them in his 'Plastic Magic' kit review that should appear in MB later in 2009, and a member of my club has purchased the same and they look fine to me.

Hi Buzz i'm building the italeri PT Boat and using 3 x graupner 400's on to 2mm shafts with 3 x 20mm brass props and using a Viper Marine 40 speed controler .The shafts i picked up from antics for about 2 quid each and they already had plastic props on them but were to big .The shafts are the ideal size for the boat but i have had to open up the openings in the hull slghtly to accomodate the tubes.
I have kept the original rudders and have used some tubing,again from antics, that fit snug over the original rudder ends and the other a fraction larger to slip over it with perhaps a drop of oil or gease to waterproof /ease the turning circle.
The review by Dave Abbot is fantastic and well worth reading.If you cant get hold of the issue give me a shout and i will photcopy the relavent article for you.I'm sure Paul wont mind me doing this .
Good luck and let me know how you get on as this boat will be my next project ,Also i dont know if you know that Italeria make a crew for this boat .
Happy boating ,Andy from Cardiff

hi i have just finished my conversion i used 3 mfa 280 motors on to 3mm shafts with 3 35mm props being run off 40amp mtronics.i increased the size of the two outer rudders to the same size of the centre rudder and discovered this does give better handling at speed.also extra ballast needs to be added to get this boat to sit in the water as it should and not plane when at full throttle, mine is now at a total weight of 2.7kilos and was working a treat until it threw a prop so now have some repairs to make but nothing serious.the crew are now available (got mine yesterday and are very detailed figures) .
detail up kits are also available but not from italia as yet ,as usual there dragging there heals releasing all the extras, just google "detail up kits for schnellboot s100 and you will find the other companys that offer these kits now if you don't mind them coming from the usa.
have uploaded some pics into my album now will post more soon
please feel free to pm me if you have any questions or looking for advice on this conversion
