Octura Wing Ding build article

A Friday old-school outrigger hydro treat! I got these scanned building articles today from a guy in Sweden that is restoring an old WD40 boat. The article is written by Jerry Dunlap and it was published in Flying Models magazine dated from October 1976.

Have a nice weekend!

10S FE KEP's from Portugal

I got a mail from Gerardo Brandão in Portugal with pictures and a YouTube video link of his re-designed Kep's FE rigger that are based on my PDF plans. I like it! :)

- 10S LiPo
- Schulze 32 200WK speed controller
- Scorpion 4035/800 BL motor
- Cupped Octura 1655 prop
- Speed: 115-128 kmh (71-79.5 mph)

Gerardo's version of the Kep's uses 3.6 deg AoA on the sponsons and its 1040 mm long.

ZippKits JAE Gas kit



The JAE Gas outrigger was designed and developed as a result of a joint venture between IMPBA Hall of Fame member Rod Geraghty, along with David Hall, Ron Zaker Jr. & Martin Truex Jr. The main difference between this hull and all the others is the use of sharp angles on the bottom of the sponsons and tub, as opposed to curved surfaces. This helps break any surface tension of the water and makes for a faster boat. This design approach has been built, developed and tested a great deal.

We don't recommend this as your first boat, as it can easily exceed 70 mph with a stock engine.

However, if you are an experienced boater, this would make an excellent first wood kit.

Full kit includes:
  • All CNC cut Birch ply for kit
  • Pre cut foam sponson cores
  • Aluminum boom tubes
  • Aluminum sponson plugs
  • Brass boom sleeves
  • Stainless boom tube attachment hardware
  • 6061 aluminum turn fin
  • Stainless turn fin mounting hardware
  • Servo mounts
  • Fuel bag mount
  • Photo illustrated step by step building and setup manual

Requires:
  • Gas engine w/ 5 inch mounts (RCMK RZ-254, Zenoah, Quickdraw)
  • 2 channel radio with 2 servos (one high torque servo (100+ oz/in)
  • 250-500 ml IV bag and tubing
  • Strut and rudder
  • 1/4x24 inch flex shaft
  • Engine collet
  • Drive dog
  • 2175 prop
  • prop nut
  • glue, paint and finishing materials
Specs:
Length: 41 inches
Beam: 25.5 inches
Weight (bare hull) 5.0 pounds

JAE Gas Full Kit
Stock Number #7504
Price: $219.00

Introductory Price until July 1st 2010:
$189.00 (plus $24.00 shipping)

Jörgen Andersson's new rides

Jörgen Andersson made a little comeback this past weekend at the first nats of the season here in Sweden. He showed up with one familiar rigger and one that was a little bit more different...

The .21 rigger he raced and won with is his old trusted Eagle .21 that he won the NAVIGA world champs in Norway with but with a different drive line. He has installed a gearbox from Dave Marles in the UK so he can use bigger and hopefully better performing propellers. The gear reduction is 1:1.65 and the propeller he used now was a .45 SAW prop = H30 with 5.4 cup! But the propeller is not optimal in anyway. He has tried a 1467 cut down to 64 mm with equal speeds but to much load so the acceleration is not too good. But according to Jörgen the throttling is super good with the geared engine.

The cowling is a .45 cowl as the engine sits a little higher in the tub.

The overall RTR weight is 2.03 kg.

Here are some more pics of that .21 rigger:















But Jörgen had another .21 rigger with him also - he calls it HydroShock .21. Its a quite light boat @ just below 1700 g RTR. The main tub is at this point made out of wood. The top half cowling is a two part carbon fiber system Jörgen has made himself. They are locked in place by guide rods and small neodymium magnets. The pipe is also quite low so there is a special molded carbon fiber radio lid that makes the pipe sit low. The front sponsons right now is carbon over foam with plywood bottoms but they will be all carbon in the future when the HydroShock .21 has gone through the developing phases...

Top speed from testing last spring topped @ 118 kmt (73.3 mph) with a ABC S15 with 3.75 cup. The developing will continue this summer. Stay tuned!
