Hi Steve The Graupner Speed 900BB Torque specs are 6-40 volts, 6,500 rpm, 54A amps, shaft 6mm, dia. 51.5 mm, length 95mm and weight 645 grams. A brushless motor like the Hobbyking L5055 600kv is 11.1- 22.5 volts(3S -6S) power 1500watts, 55 Amps, shaft 6mm, dia. 50mm, length 55mm and weight 311 grams. On 3S=6660 rpm, 4S=8880 rpm and 6S=13500 rpm. The brushless motors are far more powerful and with an ESC with handles up to 6S(22.5 volts) you would have rpm's to drive a water jet unit. Canabus
Hi All After sanding the deck, I vanished with two coats that was OK. A bit of light sanding between coats and added another coat. Check it the next day and a lot of section on the bow the veneer had lifted !!! The stern section is OK. It's the outer veneer and it's all one piece, used the same glue. Very disappointed!!!! Canabus
Hi All The Turnigy/Flysky IA6 both mode 1 and 2 have the non centering IC throttle on the left or right. If you require both gimbals to be spring centering the kits are available from Banggood. The link to the mayhem site will give an idea for the install with pics and all the part numbers. : http://www.modelboatmayhem.co.uk/forum/index.php?topic=58658... Enjoy Canabus
Hi All Repaired one of the broken cabin pieces under the aft side window and added strengthen timber forward and aft(windows). The gap under the windows to the deck, I laid down two layers of masking tape and mixed up some Selley's Plasti-bond. Pushed the cabin onto this and waited for it to harden. Removed cabin, removed the masking tape, sand the areas and spray filler undercoated. A nice clean gap!!! Canabus
Hi All Started on fixing the bits I broke in removing the old paint. The forward window had a gap in the middle to the deck, so I added timber behind the bottom of the window and filled in the gap. Masking tape to the deck and combing, a lump of filler, sit the cabin down and wait for the filler to dry. Remove cabin, masking tape, trim and sand down. As the aft of the cabin sits over the deck a fair bit, I added a plywood piece back to the combing so to strengthen the aft cabin area and replaced the bottom section under one of the windows. Remodelling this boat and building the SG&K 1920 Gentleman's Runabout is keeping me busy!!! This retirement is great, but, I still liked my old job. Canabus
Hi Guys Well I installed the aft deck and started planking. The outer trim planking is in two pieces with a joint behind the windscreen because my mate gave me the veneer for free. The idea is to hide the joints with black waterproof sandpaper used for the nonslip pieces shown on the plan. Canabus
Hi Rolf Hope ewe are successful in you bid. Other than the paint the main area of problem is the old IC engine area with fuel getting in the wood. As for cheap parts, Hobbyking. Radios, brushless motors, ESCs, batteries and props. The boat is big, so a motor in the 50mm diameter with about a 50mm 2 blade prop. We will to see what happens and maybe a few posts with pics(we love pics), good luck. Canabus
Hi Dave M CAD and 3D printers would be very handy reproducing old parts for old boats which are no longer available because the company has gone out of business. Start up a small business to save old boat fittings!!!! Oh, a 3D scanner would save some time. Canabus
Hi RNinMunich I agree with you past, respect the past but move forward. With a lot of areas of limit to IC motors we have to move to brushless motors and Lipo batteries. I have changed over with the times and running brushless motors in my Aerokits Sea Hornet, Sea Commander and a restoring a Precedent Huntsman. These old boats can go as fast if not faster with the change over. Canabus
Hi Gents I received my drive line last night and installed it and the motor mount, also added a wood block for the rudder. Fibreglass it all it. The prop is a 50mm with 4mm clearance, but, I run 40mm props on my boats this size. Canabus
Hi Lads I have a Sea Commander with a D3548-1100kv,3S Lipo,60Amp ESC and a 2 blade 40mm CNC prop. I bought a Precedent Huntsman 34" a few weeks ago and may be running a 3639-1100 or a 3648-1450 instead of the D3548 motor. As for motor mounts the aluminium angle works well and I just epoxy glue it in place. Canabus
[Score: 5/10] 34" Precedent Huntsman 34" Single Propellor (2 Blade X Type 40mm) Direct Drive to a 3648-1450kv (2 Blade X Type) Powered by LiPoly (11.1v) Batteries Controlled Through Hobbyking 100A car ESC - Comments: I bought it with a Merco 40/electric starter/radio as an unfinished boat. Changing over the brushless electric.
[Score: 8/10] 46" Vosper Crash Tender Single Propellor (2 Blade X Type 50mm) Direct Drive to a L5055C-700kv (2 Blade X Type) Powered by LiPoly (11.1v) Batteries Controlled Through Hobbyking car ESC 100A ESC - Comments: I bought it cheap and in good condition, but with no running, driveline brushes required replacing, a repaint of the deck and uppers and rewire the lights.
Hi All Adding a few more pics!!! New driveline arrived this week. Funny scale to build a boat at as the real one is 31 and1/2 foot and this is 34", also the cockpit area is shorter and the rear cabin is longer. Canabus
Hi All I bought this boat as a unfinished project with an used radio and Merco 40 motor. Sold the motor with the new electric starter and started pulling the boat apart. Removed all the old driveline etc. Repaired the forward deck and removed the paint. Stripping down the cabin to repaint, also removing cockpit floor and seats.
