Aeroic now/2022

Hi Guys,
been going though a bit of a trying time in recent months what with the new factory etc. But there is finally light the end of the tunnel, and I think you wonderful supportive slope flyers will be happy with the results.

So anyway, Rich asked me what I had, or (Aloft) will have available in the near future. I thought I'd post the reply, as you never know...some of you might be interested!:giggle:

-------

"Hi Rich - I am, I own, and design models for Aeroic Composite Aviation Products. AKA "Aeroic"

My models are sold by Aloft in the USA - or would be if they had any. Loads on order here but we are moving factory so that and the events leading up to it have caused big delays.

What will be available (On order by Aloft) are:
  • Sessanta - slope 60" - 1.5m mini allrounder (Electric in early 2022)
  • Forza - slope 100" 2.5m allrounder (Electric in early 2022)
  • Corsa - slope 108" 2.75m allrounder (Electric in early 2022)
  • Alpenbrise 157" 4m Alpine/slope soarer (Coming at the end of December)
Coming soon:
  • Redshift MKII Spada 118" 3.0m fast sloper (Coming in January 2022)
  • Sunfish 80" 2m slope aerobatic model
  • MU28 140" 3.5m scale model
  • MU32 157" 4m scale model

I'm looking at a couple more models for 2022 but no hand launch, as frankly I don't know enough about it.

Cheers, Doc James Hammond."

Well, probably time for an update here:

Frank Chang - Eagle Soaring Devices, China.
Frank is a really good learner who only wants to make his models well. He knows that this is the (only) road to success - by being better than others. He knows his own skills and limitations and so is quite happy to take advice and is even happier when because of taking advice he sees his products improving. So far, although there have been (many) times I could have happily strangled him; with mutual patience and perseverance, this partnership is working out.
With the new factory that he moved into yesterday, Frank will soon be the biggest, and the best - at least in Asia.

Aeroic Taiwan.
To back this goood start in China up, I will start a new facility in Taiwan for production process R&D, new model development, and OEM/ODM projects. This will be a protype workshop and include a large and highly accurate CNC router. Mould cost in the model glider industry is an absolute killer so I will make all our male moulds as soon as the machine is situated. Right now its on order.

New Models:
I have 6 completely new models already done in CAD, ranging from a 4m scale areobatics model, to a "teeny" 2.75M relacement for the Aresti 108.
PLUS all of the smaller models, Sessanta, Corsa and Forza will soon have electric fuselages and ALL of the new models will be instantly electic convertable.

Good things are happening!

Cheers,

Doc.
 
Latest update: May 17th 2022:

Hi to all our Aeroic friends, Here is the latest from Julia and I.

New factory:
This is now FINALLY - after over 6 months of delays operational. There are 8 new workers under training so as you can imagine the experienced guys, Frank and Fu are working thier hacinendas off with OJT plus trying to get the massive order backlog reduced. SOP procedures for each model/production process are now part of the general manufacturing processes so I hope that further inroads into quality improvement can be made.

Aeroic Taiwan Prototype/Development workshop:
I am actively looking for premises to base this new facility and I have to confess I thought it would be easier. Maybe I'm a bit picky. The (quite modified) CNC machine is ordered and last info was it was nearly finished. The search for a Taiwan home continues.

Model production:
New worker training is obviously slowing things down but apparently they are making progress on the backlog of Sessanta, Forza, Corsa and Alpenbrise models. As mentioned, everything is at least 6 embarrassing, frustating, months late. Typical china - we waited 4 months for the environmental inspection - which took 2 guys a half hour.

New models:
6 completely new models already done in CAD, plus a new and I hope exciting 3M verson of the Alpenbrise which is a new development that I just know will be good. The Redshift Spada positives are all done, and like the electric fuselage versions of the Sessanta, Corsa and Forza are just waiting for the time to get the female roduction moulds made.

CAD files finished and in hand:
4M Mu32, 3.5M MU28, Alpenbrise 3M, Aria 2.75M 'scaley' slope aerobatic model

General:
Practically, I think we need about 2 months to catch up a bit and try to get the present orders made and shipped before we can start on the new stuff. OJT for the new workers, and reducing the order backlog are the main target at the moment.

That's about it for now.

Cheers, Doc.

Thanks Wayne - actually you pointed out an error: I made the models sizes wrong...Duh!

Was:

CAD files finished and in hand:
3M Mu32, 3M MU28, Alpenbrise 3M, Aria 2.75M 'scaley' slope aerobatic model

Should be:

4M Mu32, 3.5M MU28, Alpenbrise 3M, Aria 2.75M 'scaley' slope aerobatic model

Cheers,

Doc n' Julia.
 
Sebastian grabbed an electrified Alpenbrise...and look what happened...he got electrified too!

Finally flew the Firebird
(Sessanta?)
firebird - 1.jpeg

This is an early prototype model that Doc sent to me long ago. It has waited patiently for me to toss her off a nice cliff.

I took a wild guess at CG and threw her out at Tick point yesterday and while on the nose heavy side she was loving the big air we had. She has a really nice sound, somehting all of Doc's planes seem to share (except the Gremlin). She had a surprising roll rate. I was in me mid rate setting and she rolled like a wingeron, and that was not using the flaps, just the ailerons. Sweet! I never even tried the high rates. The mid rates felt really comfortable and was impressive enough. It is that kind of roll rate that is addictively fun to play with. Fast but precise and controlled. Yummy!

This plane has some extra dihedral in her. I'm not sure if the production planes will have this same amount or not. I thought it would be interesting to see how this style plane would feel with dihedral, I was thinking I wouldn't like it, but it is not a huge change. The only difference we could identify is that gusts of wind would occasionally get under the wing and introduce some roll, only when the plane was floating around. With more energy in the plane this didn't seem to be an issue.

I had several other pilots fly her and they all liked her and had nothing bad to report.

The crow mix was adjusted in flight and the plane responded excellently. This is when the dihedral actually becomes a benefit, I'd put her in full CROW and just use the elevator and rudder to bring her in. The rudder has good authority, and really liked to use it at the top of stall turns.

For acro the ailerons completely over powered anything you did with the rudder. I'll play with this some more once I get the CG more dialed in. This is not a failing of the rudder, but more a statement of how solid the ailerons are. (They are pretty massive ailerons on this plane.)

When landing I sort of thumped the plane hard both landings as I was running short of elevator for the flare. Again, Nose heavy, and I think I kept CROW on too long and the plane was coming in with very little energy. This should be eliminated with good CG and better technique on my part.

Overall very pleased with her. Decent amount of space, not big, not too small. Flies very nicely. There is a lot to like here.
 
I thought the Sessanta was the improved Firebird. For example less dihedral and the fuse had a wing seat that actually fit the wing with its dihedral.

This is going back a bit. But it looked to me like there were some CAD/CAM issues with the Firebird.

Yes! that one IS a Firebird but the improved version is called Sessanta!

Actually there are a lot of changes between this Firebird, I think it was number two or three off the moulds, and the Sessanta that it has become.

Its those little tips directing the high-pressure vortex off the wing. Zzzzzzzip

Actually, now the roll works a bit better with the reduced dihedral.

No, this was a mistake - actually one of several mistakes on this model - that dropped though the cracks when I was not looking. I had to have a whole new mould set - fuselage and wing - made for the correct dihedral. This Firebird is one of only 3 made like that.

Tracks a bit straighter with less dihedral, and as you observe the new Sessanta does away with the gust roll that is often a feature of high dihedral models.

Yes I was surprised about the rudder. Normally its not so effective on smaller slope planes.

Like most of my models, the Sessanta has a high response wing section so the ailerons are actually designed to be around 25% of the chord, but don't have to move as far as smaller ones to get the same response. I did a whole series of low input/high response sections like this. The drag is actually much lowr than smaller chord control surfaces, but when you get to the flaps it really helps a lot as you have to veritable barn doors down in the breeze.

Thanks for the report, Wayne - its relly very useful.

Electric version coming soon. Very slightly wider front end to fit the battery and a round nose for a spinner.

Cheers,

Doc.

PS thanks to Konrad for the corrections.

I know that! Your above post has a few references to a Stormbird that look a bit out of context.
