JC pointed out to me, that the flaperon cruise setting is 5° up, not 10° up, so I thought this correction is in order. Also note, that in the original quote I referred to an 'elevon', this of course should have been 'flaperon'. I'm sorry for any mix-up this might have caused...

Hi WR, no I haven't, but I my very rough estimate goes like this: 33% engine (based on VW-derivative; Jab-2200 is more expensive) 33% avionics & other instruments 33% aircraft fuselage, wings, undercarriage, fueltank A friend of mine is building one and he thinks he can do it for appr. € 15K He's a very good at scrounging stuff and he's also going for a very basic VFR panel layout. For a ship with night-VFR instrumentation, it'll be closer to € 20K. Anything beyond night-VFR will take you nearer to €25k, so there you have it: the range should be between €15K and €25K, depending on mission profile and scrounging abilities take care, Hans

Jon, I agree with you, I must have mis-understood your initial posting in this matter.... bye Hans

In my opinion, 1/8" for those short chords is an awefull large deviation. That's way too large, even for old fashioned non-laminar sections. bye Hans

Hi Group, just a short notice to let you know that I revamped my homebuilt IBIS airplane project website. Some new information was added about an instrument I acquired. Also, I added an RSS-feed. That's it for now. so long Hans

Hi Group, those of you that are based in Europe (or making a trip to Europe the coming summer) might be interested in having a 2006 calender of European aviation events. On my RJ.03 IBIS Canard website, I compiled a list of air shows and aviation trade shows that take place this year. Go to my IBIS project website then click on the menu option 'nice to know'. On the next page, you'll find a menu choice 'European events'. enjoy! cheers, Hans

decoupling in the sense that non-existing push-rods can't actuate the control surfaces when a wing is flexing. This is one of several flutter input modes: at high speed, when entering a gust, the wing suddenly flexes and the fixed aileron push rods can induce a control surface actuation, which - at certain frequencies - might reinforce the wing flexing. bye Hans (IBIS builder)

I don't know whether reliability and weight are an issue, I'm not into hydraulics to be able to tell. However, I do see a potential advantage that hasn't been mentioned before: Hydraulic lines would de-couple the potential differing flexing modes of a wing and its control surfaces, which could potentially reduce flutter risk. My gut feeling is, that this advantage will be largest for high aspect-ratio wings. Does this make sense to anyone? bye Hans (RJ.03 IBIS canard builder)

also: compared to current offerings in Europe, his offer is over-priced by a large margin. A SpeedCanard can be purchased from € 29,900.00 (basic equipment) up to € 62,500.00 (equipped much like Todd's). See: Aero-Auktion.com bye Hans

Hi, what about calling this project a 'Long-Ish' ? bye Hans

Hi Gang, there's a new RJ.03 IBIS experimental aircraft website online. Gerald W. Gay is an American builder who set up shop in his garage. Check out his site. bye Hans

I feel the IBIS canopy is too long and too light to consider a flip forward/flip back solution. For sturdyness, I want to keep the original configuration (two hinges on the port side) but I'd like to have those hinges out of the airflow. Currently, they stick out quite a bit, because of the round shape of the lower canopy side. bye Hans

The CNC cutting is doing the all the aircraft metal parts that are fabricated from flat plate. We're also having wing sections templates cut this way, but only so because we were dealing with a CNC cutting outfit for those flat plate aircraft parts anyway. Also thanks for pointing out that a template can possibly cool a cutting wire enough to create trouble, I hadn't thought about that one, yet... bye Hans

Hi group, where do you gals & guys put the pitot tube on a canard? I don't like the exposed position on the nose cone, because of sometimes rough hangar handling (by others... ). Are there any other options, that would result in a clean 'signal' for my instruments? bye Hans

Larry, for my IBIS project I'm also going to need a couple of hinges and I would be very interested to learn more about your design. The standard IBIS canopy hinge line is outside of the fuselage, so I'll end up with to metal parts sticking out of the starboard side. I'm looking for a way to have them 'embedded' to reduce drag and to end up with a cleaner visual appearance. What kind of hinge did you design? take care Hans

Hi group, just a small update: for my IBIS project, I'm teaming up with three other builders (one also based in Germany, two based in The Netherlands) to have our flat plate metal work cut by a CNC water jet cutter. We'll end up with a 0.1 mm precision. There is almost 250' of cutting to do per IBIS parts set. We're also having IBIS wing and canard templates cut out of metal to the same precision. When it's ready, I'll have pictures on my RJ.03 Ibis homebuilt aircraft project site. One warning to others: if you have your metal stuff cut with a laser CNC cutter, the local heating will harden up the edges of the cut parts. Then, if you have to bend those cut out parts to shape, the hardened edges will crack and you have to weld them up to make them reliable again. A lot of work for nothing, at great cost.... This is the reason our IBIS group is resorting to CNC water cutting. Thanks a lot to Hans Holsink for relaying his bad experiences with laser cutting... bye Hans

I think the only really valid reason for wanting to have this precision is when you intend to have stuff cut out by some CNC process. bye Hans

IBIS sports flaperons, aka single control surfaces that combine aileron and flap functionality. Also, to reduce drag, on IBIS these are used with a -10° cruise configuration setting. Combining rudder and stick inputs is done with a mechanism called a mixer, of which I include a picture below. This one is from the IBIS that is being built by Dutch friend Hans Holsink. bye Hans

Quicky Q2 Sale on Ebay bye Hans

PDF files can be used to some extend, provided that: 1: you instruct your printer driver that no scaling whatsoever is done during the print processing phase 2: you use the exact same paper size the PDF-file was created for Even with these precautions, some small errors may occur, most likely because the printing process may heat up the paper (as laser printers do). This heating up may elongate the paper a bit. If this happens, the size change will not be exactly the same on the X- and Y-axes... bye Hans

Hi group, just a quick note to let you know that I'm currently looking for a long term charter of an GA airplane, starting about now until the end of November 2006. Since I know that many Europeans frequent this forum, I though I might as well try it here. I need to be allowed to fly it with a European JAR/FCL license and need the plane in Germany. As long as conditions are VMC, I'd be flying it between 5-7 hours a week on average. Ideally, the plane should be equipped for night VFR operations as a minimum. Any ideas, hints, etc? bye Hans

today I've extended my list of links to free design software with two software titles that are FEM/FEA solvers. Go to my my RJ.03 IBIS experimental aircraft project site, you'll find the links under "Links" - "Software". If you have suggestions of other relevant free design software to include in this list, please let me know... bye Hans

Did you check how serial # 62 N202FW did the paperwork? bye Hans

Todd, just curious: in that other posting of yours announcing your SC purchase - I'm still envious - you mentioned that it is not registered as an experimental. Would you still be allowed to make those panel changes you propose yourself, or would you need a certified mechanic to do the work? 155 kts? You must have purchased the 180HP variant... Good for you! bye Hans

Jon, - are you proposing an OpenSource Canard (OSC?) of sorts, or what is your intention? If you plan an OpenSource project, check out the legal framework that is offered by GNU.org. It might apply to what you intent to achieve. - are you proposing a design from scratch, using the LongEze as a reference design to start with? If so, you might want to visit the list of links that I maintain at my RJ.03 IBIS experimental aircraft project site. Most of the software titles on that list can be used for preliminary (aerodynamic) design. The coming weekend, this list will be extended with links to free FEM/FEA software. I'm also checking out free CFD software, so the list will grow further still... bye Hans
