Regarding propshop and other possibilities you could look up protean design on Facebook. He has some nice items. And I would stay on 4mm shaft as you will get the largest range of props to choose from.
HI there With that setup you are trying to make a boat fly :-) Several members of my local modelboat club is running the same setup as I do with my Classic. And that is a Graupner Compact 260Z 1380KV for the Classic 2S is more than enough and 3S will still make the Queen fly over the water. So a 1100KV on 3S with a 3 blade semi racing prop will do a great job. You could also cut down on amount of "S" on your existing setup and program the ESC to slow start.
Hello Allen I believe that I do have the full instructions and plan with my half build kit of Elke, I can dig it out and check it out, and if they are there, I can take some pics of it if you need it ? BR Carsten
[Score: 9/10] 22"/1000g Classic Single Propellor (3 Blade 30mm) Direct Drive to a Graupner Compact 260Z 1380KV (3 Blade) Powered by LiPoly (7.4v) 2Amp/h Batteries Controlled Through Graupner 18A (10Amps) ESC - Comments: This is a aero-naut Classic and I would say that it's a second revision, as there has been changed several items, compared with the one my wife build 3 years ago. 1: The wind shield is now fixed in slots in the deck and not just glued to the edge of the cockpit opening. 2: There are now padding and leather for the seat included. 3: There are a few etched details for the instrumentation, steering wheel and step plates for the deck. 4: There are notches at the break off parts that will help in fixing the sides when gluing them in place. I used the same set-up as my wife's which is: Graupner BL Compact 260Z 1380KV with a Graupne ESC 18A FWD and REV. The shaft is replaced with a Robbe 4mm (no 1442) as the one provided is a flimsy part that will not withstand the motor set-up. Prop is a 33mm Graupner racing item. It will be running on LiPo 2S but if one need a rocket it can run on 3S. Great fun to build and performs great on the water
My wife did build one back in 2013 and I can see that they did update the kit with good things. 1: The wind shield is now fixed in slots in the deck and not just glued to the edge of the cockpit opening. 2: There are now padding and leather for the seat included. 3: There are a few etched details for the instrumentation, steering wheel and step plates for the deck. 4: There are notches at the break off parts that will help in fixing the sides when gluing them in place. Choice of motor: I'll use the same set-up as my wife's which is: Graupner BL Compact 260Z 1380KV with a Graupne ESC 18A FWD and REV. The shaft is replaced with a Robbe 4mm (no 1442) and a 33mm 3 blade prop from Graupner (GRA-2299.90) as the one provided is a flimsy part that will not withstand the motor set-up. It will be running on LiPo 2S but if one need a rocket it can run on 3S. 😱 Been using LiPo's the last 5 years without any fires or explosions. They should just be treated with care, balanced when charging and not overloaded. 😎 BTW the last picture show then new vs. the old kit of the Classic

Quick, "cheap" and fun just like a "Kinder egg" 3 things in one packaged ;-). The set-up do allow it to run on 3S but it's more scream than more power. Short video https://youtu.be/rIzBSnTaxtA
[Score: 8/10] 28"/1000g Phantom Single Propellor (3 Blade 35mm) Direct Drive to a Turnigy D2836 1100kv (3 Blade) Powered by LiPoly (7.4v) 2Amp/h Batteries Controlled Through HK 30 A Boat ESC ESC - Comments: Bought it as partly build, and had to take it more or less apart to make it straight. Used a PU glue for the first set of planking, what a mess but it's strong. First trails on water showed that the balance was wrong so have to re-arrange the electronics. Unfortunately the trails also revealed that I had missed something with the sealing (my wife used the same materials for her Classic without any problems) so first of all I'll have to strip parts of the mahogany plating down and redo it :-( before I'll do any thing more on this model.
[Score: 7/10] 15"/500g Skimmer Single Propellor Direct Drive to a Speed 400 / 6Volt Powered by LiPoly (7.4v) 1Amp/h Batteries Controlled Through Robbe air control 819 Lipo ESC - Comments: Skimmer built from Model Boat plans back in 2010 (Glynn Guest). I use a 5.5"x4.5" prop. It is hard to control as it tends to skew to the side due to the twist of the drive unit, I think I didn't gave it enough angel of the motor mount. If I was to do another one, I would add small rails on the bottom to give it just a bit more direction stability.
[Score: 8/10] 28"/1100g Lightning 46 Single Propellor (2 Blade X Type 35mm) Direct Drive to a Power 600/19 (2 Blade X Type) Powered by LiPoly (7.4v) 2Amp/h Batteries Controlled Through Robbe Rokraft 120µ ESC - Comments: Old school Robbe kit that I found 2 years ago.Build as intended except for the use of LiPo. I have only tested it with 2S mA >Cell but as the weight is less than half of the intended cell NiCD it performs great. The plan is to get my GPS logger on it. And also to test with 3S mA LiPo.
[Score: 8/10] 28"/1900g Palm Beach Single Propellor Direct Drive to a Roxxy 3656-06 1800KV Powered by LiPoly (11.1v) 4Amp/h Batteries Controlled Through Aquastar 120A. ESC - Comments: Billing Boat Palm Beach, it comes with a 28mm Kehrer Jet, and suggested motor is a Johnson 700. I bought a adapter and used a BL motor for more power. It's good fun and the only down side is the way to control the jet drive. There are no solution in the box and I have had some challenges to come up with a stable set-up. But hey still lots of fun .
