    A 2L"medium" for front seat solo?

    I just simply posted the link to my new project web page but it appears the "internet smarts" somehow inadvertently provided a description of my old aircraft. That was unintended. Haha! That's why I don't post...... all too clever for this old brain!

    A 2L"medium" for front seat solo?

    Hi WTR388. I rarely chime in to web blogs but your's caught my eye. Although you may be too advanced with your project now to change course, I thought you may still be interested in a few pics of a (my) Sonerai variant that is re-engineered to pilot from the front seat. You can see the pics...

    Prop for Rotax 912 100hp

    Hi folks. Just stumbled across this thread. Just to confirm, both aircrafts had 65-66” props. 2 blade on SGS and 3 blade on SRS. If you use a 66” 2 blade, make sure there is enough blade area to handle 100 hp at approx 2400 rpm. Cheers

    The lack of portability ( hi hangar costs ) killed ULs imop

    Couple of images of this folding wing, trailered aircraft. For more info go to the above link.

    The lack of portability ( hi hangar costs ) killed ULs imop

    Hi folks. I have included a link here to another thread that has pics of my aircraft that is trailered on a regular basis. Time to unload from trailer is typically less than 5 minutes and time to rig is also typically less than 5 minutes including preflight inspection. So, 8 to 10 min in total...

    VH-SRS 170 knot Sonerai II

    Thanks for all the input. A huge cultural lesson! I knew there was a transition from Europe (Rotax) to US (traditional) but didn’t realise it was that prevalent. Fascinating ! Cheers.

    VH-SRS 170 knot Sonerai II

    Hi TTF. Just curious! I find it perplexing that you find it perplexing. Seems like a natural fit to me!?!? There are at least 5 Rotax powered Sonerais in Australia. That is probably one third of the fleet. This is not a negative comment, just that despite US folks liking US engines, there’s...

    World Record Plane - 12 years on

    Hi Smokey. 912s from my experience are set and forget. If installed, flown and maintained according to manuals, they are as close to bullet proof as aircraft piston engines get. Weight??? Need to consult manual. Rotax publish detailed item weights. Cowls. Yeah, hard. I started with a different...

    VH-SRS 170 knot Sonerai II

    With the fuel tank relocated to the back, and soloing from the rear as is the norm, I’m almost certain that could be made work. Now get to work on the W&B spreadsheet ha ha.

    VH-SRS 170 knot Sonerai II

    That’s one interesting plane from your hometown. I love the concept of flying at good speeds on such a low hp engine and available at a price us mere mortals can afford. For me that’s much more elegant than just stuffing extra hp in. Well done to the Gazaile folks. and thanks for the link.

    World Record Plane - 12 years on

    Thanks for your reply Smokey. Sounds like you’ve had an incredibly flying career! I’m envious. I too ended up with the Sonerai type aircrafts after a couple of RVs, also in the 90s. That Sonerai you bought was one of the best looking Sonerais ever in my opinion. I have always admired it since...

    Ha ha. I think you have an uncanny knack of explaining the funny world we find ourselves in with unusual amount of forthrightness, insight and elegance. Thanks for explaining these oddities to me again.

    VH-SRS 170 knot Sonerai II

    It’s clear that the Risen is an efficient aircraft, but....The bit that miffs me is when manufacturers (many) claim a Rotax 912 in their airframe uses 2 1/2 litres per hour less at 75% than Rotax Engineers and technical specs claim (or 912s actually use), as Risen do in their specs sheet. I’m...

    VH-SRS 170 knot Sonerai II

    Ah, Dave.... Lightning Bug..... Penny dropped, I just realised who I am taking to. Is there a thread that I can get an update on your projects Dave? If not, now that you’ve got our interest, perhaps you can give us like minded nuts an update here? Or start a seperate thread with an update!

    VH-SRS 170 knot Sonerai II

    Thx Dave. Except for my jibe, I think it’s all been positive and fleshed out a bit of useful discussion. Also a few ideas and thoughts that similar minded speed or efficiency nuts might find mildly educational or at least enjoy reading. Even Mark might be inspired to build that better doghouse...

    VH-SRS 170 knot Sonerai II

    Hi Thank you for the detailed and clear description. That fills in the gaps and makes perfect sense of why the ambiguous claims and marketing. Really appreciated. It appears Risen have done a fantastic job and put a huge effort into this project and it sure looks exciting. I didn’t set out to...

    VH-SRS 170 knot Sonerai II

    Hi. FAI have different types of speed records. All records can be flown at your chosen altitude as I recall. The chosen altitude will usually depend on the type of aircraft (turbo or not) and the type of record chosen. I have provided more details in a post earlier today that hopefully might...

    VH-SRS 170 knot Sonerai II

    Hi Mark. Firstly, thank you for your kind comments. Really appreciated. I did speak with John at Oshkosh in 2011 about transferring my testing and ideas on to one of his designs in return for a discounted kit for me to apply them to on the other side of the world, but he wasn’t interested and I...

    VH-SRS 170 knot Sonerai II

    Hi Dave Thx for the kind words, but I need to clarify the type of World Records I attained. There were 2 aircraft Efficiency World Records, but that’s another story. The speed records were for 1 way flights, ie point to point. This means wind assisted. All the FAI point to point distance speed...

    VH-SRS 170 knot Sonerai II

    It appears there are 2 different specs for the aircraft. I’ve just found an alternate website that shows a 600kg MTOW rather than the 472Kg in the video and other marketing. This is a good thing, but my comments above still apply re performance/economy and to usage of this aircraft in Europe and...
