Hi IBob and thank you for replying. I have already purchased the VG's from JG and will install as advised. However as mentioned in a comment I previously posted, I suspect while VG's may help, traditional flaps would out-perform VG's (I suspect). RKind regards Allen B

Sorry for my ignorance but what is/are "Gurney Flaps" ? Allen B

I have bought the VG which I will attach soon and see what difference they make. I know about the Swiss pilot (Victor) and will follow his suggestion re placement of the VG's. I suspect the VG's may help a touch but I also suspect VG's wont perform as well as a decent set of flaps. Again, maybe it's just wishful thinking by me ?. Allen B

Hi Nev. I agree that Flaperons is not the way to go. Idle RPM (Rotax 914) is around 1,700, so all good there. I have tested with many stalls (at between 2,000 to 3,000 feet) and the actual stall is quite gentle, with considerable buffeting but doesn't really drop a wing of a serious nature.

Thanks for this suggestion however from my small experience with flying the RV-12 shows (at least to me) Flaperons isn't the way to go either. But thank you for your suggestion. Allen B

Thanks for this suggestion Diegg, however I do like the Tapered HDS wing, but less of a challenge for the landing would be nice... (just wishful thinking I suppose) Allen B

Hi Nev and thank you for your prompt reply. Regarding the approach, I have tried various approaches and despite having a couple of thousand hours and flown a number of different aircraft, I find this small aircraft more challenging than any other that I have previously flown. I suspect the rather high stall speed (a bit tricky to replicate and pinpoint the exact stall speed) of anywhere from mid to late 40's knots, requires a fairly flat approach over the fence when landing. I feel if it had flaps, it would allow for the nose of the aircraft to maintain a higher attitude while the airspeed could be a bit less over the fence. I acknowledge the full length ailerons would create a challenge to convert, to shorten the ailerons and utilise the inboard section/length of the existing ailerons to become flaps. So I just thought I would ask if this mod has already been done somewhere out there in Zenith land ?. Allen B.

Good morning/afternoon. I own and fly a 601HDS. Has anyone successfully designed and built flaps for the Zenith 601HDS. I find my HDS has a reasonably high stall speed and as such is not a pussycat to land. Regards Allen B.

Good morning/afternoon. I own and fly a 601HDS and have just found this post (question) and staying with the same question asked in the Post above, I can't help but wonder if anyone has successfully designed and built flaps for the Zenith 601HDS. I find my HDS has a reasonably high speed stall and is not pussycat to land. Regards Allen B.
