It's a sad day!. by wunwinglo Lieutenant   Posted: 5 days ago
I can well imagine how you feel about your i.c. models. My recent renovation/recommissioning of my late father's Vosper MTB is kind of ironic in that it last ran in 1962 when noise suddenly became an issue. Mind you, it was VERY loud. My rebuild, needless to say, was centred around brushless motors and lipo's. But I also put an excellent sound system into it as it was so quiet. The system, by Action Electronics and is nice and loud as per the full-size but it does seem ironic that I felt the need to put sound(noise) back in! I use lots of small diesels in free-flight model aircraft and still hugely enjoy getting them 'singing' and savouring the wonderful smell in the car going home afterwards!

47" Fireboat power question by ronrees Sub-Lieutenant   Posted: 21 days ago
Hi Shaun, This design of hull forces the craft higher and higher the faster it goes. When it is high on the plane and almost hanging on the last few inches of propshaft it can fall off the plane either way, usually to the right (Starboard) side because of engine torque. The full size boats were fitted with 2 or 3 engines to help counteract this. The British Powerboat Company, who originally designed the hull that Vospers copied back in the 1930s/40s also noticed this which led to double skinning the hull with 1 inch thick mahogany for extra strength against pounding and falling on the waves. Lowering the drive angle of the propellor shafts and adding more weight from the C of G back to near the stern. We build this 3 screwed designed hull with one mainshaft usually so do not have the benefit of shaft rotation to stabilise the boat at speed. It was in the 1960's that Fairey engineers had the same problems (Swordsman,Huntsman etc) They came up with large transom mounted powered Trim Tabs. Their boats had similar problems and only one shaft in the main. I suggest you try fitting 2 x 2 inch wide by 1 inch deep trim tabs at the very bottom of your transom midway between the keel and the chine as well as move your battery packs forward a bit initially. Try some fast tests with this, you only need 2 to 4 degrees of down on the tabs initially. Add removeable weights near the CG as needed, a bit at a time but don't stop the bow lifting up onto the plane. Have fun, best of luck. Ron Rees

Which Paint? by andyhynes Sub-Lieutenant   Posted: 29 days ago
A couple of years ago i scratch built a 1/24 scale Vosper Long boat MTB 510. I spray painted the hull and super structure with Halfords white and gray primer. The Hull was given coat of Matt clear laquer Spray (Plasticote). The deck and super structure were also coated in a matt laquer spray. This product was Rustoleum Crystal Clear Matt Laquer. I have used this product before on acrylic base paints, and had no problems. Do not use on oil based paints as it will crinkle the surface. The Plasticote product i used on the Hull was fine at the time but a couple of years on the surface has become crazed. so i will have to repaint the complete hull sometime in the future. Can any one out there recommend a paint combination or product that is satisfactory, and will not craze like an old masters oil painting from the 1500s.

H.M.S. BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 1 month ago
Thanks all for the responses. Donnieboy - have thought out the plumbing, which is simplified by using a cooling pump. See future episodes! Doug - appreciate the concern regarding the red ESC wires. Have been trying to understand the rationale behind that theory. If all ESCs share a common input voltage, i.e. from one battery, what would the connection of multiple red wires do? Can understand if there were several unique power sources, but that is not the case here. Perhaps with your electronics background you can explain. Colmar - Used the angle on the scale drawing. If it were good enough for Vosper, should be good enough for me! Think it close to 7 degrees anyway. Think short shafts with oilers should help. Have heard of bushings running dry and seizing with these high speed motors. The initial props are scale versions of the originals. Rather suspect they will not prove to be ideal. Have purchased some 2 blade racing style props for a future test. They have a much coarser pitch and are designed for high speed motors. Intend to use plastic props initially as they are cheap enough to experiment with. Perhaps others have a comments on the cavitation question?. Incidentally, this is my first high speed boat too, but there is much of information on both this web site and Model Boat Mayhem for guidance. Posting questions always generates useful information. Look widely though at all types of fast models, MTBs, RAF launches, E Boats etc. - it has all been done before!

Cabin roof mechanism by BOATSHED Fleet Admiral!   Posted: 2 months ago
I still have a 34" Raf crash tender still unbuilt that I bought back in 1994 when they released a run of 50 on the 50th anniversary of the model in the Model Boats magazine. I also have a Vosper 46” RAF Crash Tender Kit By Vintage Model Works sitting in my shed. One day I will get around to building them Along with restoring my Sea Hornet, Sea Commander, Sea Queen and my Huntsman along with several other boats, including an MFA Spearfish and a Stratos Interceptor, Hydrofibre Pipedream both of which were the same company just that they had a change of name. Along with at least 3 others. I will do them sometime.

Perkasa Class by CB90 Commander   Posted: 2 months ago
Perkasa MTB A favourite model boat there must have been hundreds if not thousands made. When I brought mine there was a choice between two sizes 36in (90cm) or 48in (120cm) and then you could choose between a wooden hull or a fibreglass hull. I went for the smaller boat with the fibreglass hull. this was back in the 1980s. Background of the boat The boats Perkasa class consisted of three motor torpedo boats built by Vosper (UK) for the Malaysian Navy as follows:- Perkasa 150 Penula 151 Handalan 152 This model has 3 motors, port & starboard are Graupner 600s and one 700 type in the centre runs 3 ESCs front and rear guns operate via servos, with flashing LEDs down the barrels.

Calling Devon boaters. Help! by wunwinglo Lieutenant   Posted: 3 months ago
My 95 year old uncle is a former MTB captain living in a care home in Exmouth. His brother, my late father, built a nice Vosper MTB model in the fifties that has not run since 1962. I have recently restored, upgraded and recommissioned this model and I would really like to show my uncle her running on a lake. Unfortunately, the lake at Exmouth has been filled in recently and the nearest alternative that I can find on the net is about 45 miles away which is too far for him to travel. The model is now electric and so is quiet, about 40 inches long and a fairly hot performer at full chat. If you are active in this area, I would be most grateful to be informed of any suitable closer waters and the requirements to access it. Thanks guys.

Aerokits Patrol Torpedo Boat by RNinMunich Fleet Admiral!   Posted: 3 months ago
HiMB, sorry for delay replying, just got back from a Ten Pin Bowling League Cup match, we won 4:2 and through to Round 5 😊 Ooops! I can't think of any type with a gun tub slap bang in the middle of the bridge. 😲 Otherwise I think yours is a simplified version pretty much based on the US produced ELCO PTB. Probably the 80 foot version, known as ELCO 80 (wonder why 😉). Modified from the original Vosper / British Power Boats designs. More of these were built than any other version and most used in the Pacific. The USN called these boats PTBs while ever other navy at the time called them MTBs. Also suggesting that your model is based on the US ELCO version. Here you can find oodles of photos of MTBs, MGBs and PTBs. https://www.pinterest.de/pin/417145984205535643/ Attached is a photo from this site showing the bridge, foredeck and forward gun tub. I have loads more like this. If you like I'll sort out a bunch and post them here or email them as you wish. Battlecrafts are good, well detailed. BUT, I was disappointed when I bought a set of 4.7" for my destroyer that nothing moved 😡 Now trying to figure out how to mod them without wrecking them. The guns in the tubs are Twin Browning 0.5" 50 CAL (for Calibre). Means that the barrel length was 50 times the bullet calibre! I.e. 25". Cheers Doug 😎
