A/A .45 engine

Here are the first pre-production pictures of the new AA .45 hydro engine manufactured by Axe Motor Rossi in Italy. The A/A engines are backed by world famous Allan Hobbs in the US and they will be sold through him under the A/A brand (A/A stands for Aces). What I know it will also be available in the Axe Motor Rossi costume.

If you have an old MAC .45 engine a lot of parts will fit that from the A/A .45 engine. Like piston and liner, intake system and crankshaft. But do note - the crank-pin is different in size together with its bushed con-rod.

- The bore/stroke is the same as an MAC .45 (that would mean 21.2 mm bore and 21.1 mm stroke)
- Exhaust port timing: 185 deg
- Transfer/boost port timing: 132 deg (26.5 deg blow-down)

The A/A .45 will be sold in the US for $400 by Al Hobbs.

JAE .91/1.01HG PDF plans

Here are the plans for the JAE .91/1.01HG boat!

Once again this boat has been tested and is ready for the RC hydro battles. There is no performance difference between the "H" style and "G" style sponsons and overhangs on this boat is not necessary.

Install the drive line with a slight gentle "S" bend in the stuffing box. Use the same set-up and construction techniques for this boat as all the rest of the JAE fleet. I.E: the strut pushed down flat as far as possible on top of the bottom ski sheeting.

Start by setting the sponsons 22" to 24" apart inside to inside. Remember, the wider the
sponsons are set apart the more stable the boat will be in rough water. The turnfin that will be available from ZippKits for the JAE gas boat should work very well on the JAE .91/1.01 boat also.

Rudder and prop placement relationship is not critical. Take the appropriate steps to insure the very solid mounting of the turnfin and chose a good quality strut and rudder.

"I want to stress that the JAE .91-1.01 boat is a Gladiator and is not for the novice or feint of heart RC boater."

The JAE .91/1.01HG prototype boat weighed right at 9 lbs (4.08 kg) RTR with the CMB 1.01 motor installed. The prototype, in very rough water, ran 85 mph [on radar] effortlessly (136 kmh). This performance was accomplished with an old and tired Rossi .90 / Octura 1667 combination. With the CMB 1.01 the JAE .91/1.01HG's running performance is literally brutal!

As of now, the JAE .91/1.01HG boat completes the JAE hydro plans offerings from the JAE team. I hope all who have built or plan to build a JAE boat have enjoyed the ride as much as we have!

I really want to thank you Niklas [ NE-Stuff ] for all your help in making these plans available to all who have wanted them (NE note: your very welcome - happy to help U out!).

Note: We do have a .90 "twin" nitro boat built and in the process of completion. After testing a decision will be made if the "twin" plans will be released for general consumption.

Later, Rod Geraghty

Update March 17 - YouTube video!
"This very short video was taken Saturday March 13 2010 at Huntsville... The water was very rough and full of holes. The motor is the CMB 1.01 and a V967 prop was used on this short run. The motor was still cackling “fat”. Once again, the boat does absolutely nothing stupid in any water conditions... [This boat is a beast!]

There are no plans at this time to kit this boat but the building plans are available on Niklas Edlunds website. The little “hopping” you hear in the corners is that V967 in rough water playing its games... / Rod Geraghty"

JAE GAS prototype in testing

Update March 17 - YouTube Video!
"This video was taken Saturday march 13 (2010) during the test session in Huntsville. The boat is the prototype JAE gas boat with a “box stock” RCMK rear exhaust motor [the motor is turning 16,600 rpm]. The only smooth water was right in front of the drivers stand. This video does not do justice as to how rough the water was during this test run. The wind was blowing across the course from the drivers backs...That is why the water is smoother right in front of the drivers stand. The boat isn’t hopping, it is being “launched” off the tops of the rollers... We are pleased to say the new JAE gas boat does absolutely nothing stupid in any water conditions! ;)

This run was with a Voodoo 7520 prop. We have several 3” plus diameter props coming to try and all indications are that 75 mph (120 kmh) will be attainable with this JAE/”box stock” RCMK combo [we haven’t even set the head clearance in this motor yet].

We have another gas boat prototype in construction and the same tests will be run with a “box stock” 260 Zenoah.

Note: Once again, the only adjustments required on this boat are prop selection, pipe length and needle valve. / Rod Geraghty"

"These are some pictures of the 1st test run of the JAE Gas Rigger prototype speed was 65mph on the radar gun with full length rudder that needs to be shortened and also needs a smaller turnfin and more prop than we had with us it turned a 1667 with no problem. This was with a STOCK RCMK EVO rear exhuast. The boat really handled well you could put it right on the buoys or out wide it was a very well manered hydro no bad habits. Looking forward to finding the right prop and racing it this season. The guy holding the JAE gas hydro is David Hall the designer/builder. He also has another JAE Prototype designed for the Zenoah."

JAE .21G2 in action

A Kently Porter built JAE .21G2 rigger kit in the hands of Aaron Alberico from Australia. The rigger has a Novarossi Flash .21 3-port motor in it and it's doing about 70-80MPH in the videos - thats about 112-128KMH. Nice to see some RC boating now when the lakes in my part of the world are all frozen. :)

Back From The Alps

Im back from the yearly skiing trip to Alpbach in Austria now. It was nice! The weather was ok but slightly too warm. That meant you had to ski from early morning until the snow got too soft at lunch but that is perfect for me - LOL. Ski for a few hours and then have a few pints of the local brew...

We have WAY more snow in up here in Sweden then in Austria!

Alpbach info.

Alpbacher Bergbahnen info.

A life saver - hot coco and rum. Yummy. :)

The slopes start to get too soft for my knees - time to drop down to Asthütte for some reinforcements. :)

One of the better slopes - we call it "Guldbacken".

Asthütte view to one of the slopes taking you there.

The youth-table at the wonderful Zottahof restaurant up on the hill. Its small and hot.

If in Alpbach - rent your gear at Iggys!

The other slope down to Ashütte.

Here's where my knee broke one year ago - coming out of the woods. This year I only crashed (mildly) once.

Anders thinks he can have three more Lövenmilch at Zottahof... I beg to differ. LOL. Lövenmilch @ "Zotta" is a warm get-me-home drink when we're done eating. And after one you're for sure DONE. Its 0.5L of a milk based drink with what we think is a hefty dose of Stroh Rum and something else... Lovely.

A few of the days it was quite nice at lunch time.

This was our last day in Alpbach - it was snow, rain and fog... Photo taken from the Zonnwend house we stayed at.

My knee support helped me all week. Even with the main ligament broke off one year ago here in Alpbach and with a crack in a miniscous I had no pain all week. Nicers.

If you want to stay at a very friendly house in Albach we can recommend House Zonnwend. It was very good and smack in the middle of the small Alpbach village.

No trafic jams here...

Last day we had lunch at Zirmalm resturant - this is shot from their parking lot down towards Inner-Albach. Fog and rain. Time to head back home.

This is at Zottahof resturant just before it went dark. The lighted slope in the background is down at Reith. We never went night-riding though (with skiis on - LOL).

Inside the hot Zottahof.

The wonderful omelette at Zotta. Gourgeousely good and yes, I was full after this one.

Its the Alps!

Inner-Alpbach the last day we where there in 2010. Bye, bye - see you next year...
