Experience with the Viper SD4?

Talk about airplanes! At last count, there are 39 (and growing) FAA certificated S-LSA (special light sport aircraft). These are factory-built ready to fly airplanes. If you can't afford a factory-built LSA, consider buying an E-LSA kit (experimental LSA - up to 99% complete).

And, probably most important, is seeing other traffic. Traffic can be above, below, or at the same altitude. So, it depends on where the traffic is.

So it sounds like no one in the crowd has flown the Viper. Not surprising when there are so many wonderful & proven LSA’s already on the market.

@Sling 2 Pilot I am definitely considering the Sling 2. In fact, my original first choice was the Sling TSi with the 915iS. However, the price range was just a bit out of my budget range. I’m now taking a closer look at the Sling2, which is in my budget range, and I may follow in Cam’s footsteps. It’s certainly a gorgeous plane. Do you know of any Sling2 owners on the east coast that would be open to taking me up for a spin in their plane? I currently live in Southern NH but we’ll be moving to Charlotte NC later this summer.

@Tim Taylor I have flown the RV12 and I love that plane, however, my flying partner, the wife, has made only 1 request - parachute. And the RV12 does not have that option.

@MrMorden I have about 40 hours in high wings (C172, C182) and the rest in low wings. I’m not opposed to high wings, I really like them, but if I had to choose, I like the view from the low wings a bit more (just a personal choice).

@Warmi I’d love to hear more about your Sting experience (handling, performance in turbulence, speed, etc.). I had the chance to speak with the TL dealer at Sun n Fun this year and sit in their planes. Same question to you about east coast Sting owners? I’d love to go up in a Sting, very slick plane.

Various articles, reviews, and owner reports online converge on a cruise speed of about 112kt.
It was really designed with a constant speed prop, which we know is not permitted under LSA rules. Go EAB with the prop and you will exceed the mythical 120kts.

I just got back from tooling around, playing with my VNAV function and saw a respectable 110 @ 5300 or so. Winds were light. Lastly, it’s one of the only LSA’s certified everywhere else at 1540 and holds 39.6 gallons. Enough said.

I live in Hollis NH and fly out of Nashua Airport. Currently I rent from East Coast Aero Club (just got out of one of their Warriors) and I have really enjoyed being able to fly so many great planes (trainers, complex, high performance), but I think it’s time to get my own.

Concur.
That is based on reports from those with experience and reviews. As an S-LSA, with BRS installed, it is a heavy airplane. Fully equipped, with 912is engine, it comes in at better than 900 lbs empty. Comparably, climb rate is a little less than most CT’s and econ cruise (5200-5300 RPM) is just below 110 kias.
The 912is produces slightly more torque than its carbed brother, at 100 hp.

That withstanding, I love the Sling 2. Owner reports are very positive.

I’m at MSV, we should get together somewhere in between.

Speed and Vh limitations notwithstanding, any E-AB equipped with a constant speed prop would be in clear violation of the LSA rules, thus could not be flown by a Sport Pilot, or any higher rated pilot operating under Sport Pilot rules.

That would be great, thanks. I’ll reach out to you in a couple of weeks to see if we can find a date that works.

Another vote for the Sling. The Sling 2 is what got me to be a Sport Pilot. Love the plane, but needed a bit more useful load (as a bigger pilot). Have you considered the Sportcruiser? I love mine. Bunch of fun to fly and the early ones are priced very well and perfect for an E-LSA conversion.

Sorry, no experience with the Viper SD4.

RTK, thanks for the feedback. I truly never believed that I would have a problem like this, but there are so many LSA’s with a proven design, great handling and a really nice interior (Sling2, Sting4, SportCruiser, Bristell, RV12, Astore, Evektor) that it makes narrowing the decision really difficult, especially since the empty weight, speed and fuel burn are all roughly the same.

I think it’s going to come down to simply flying each plane and, assuming enough empty weight for my wife and I, deciding which plane we like to fly the most and find the most comfortable for extended periods of time.

Everything that I’ve read about the Sling2 (including Sling4 and TSi) has been overwhelmingly positive. I’m going to fly out to MSV and take a ride with Sling 2 Pilot in a few weeks, once we get our house on the market. That will mark the beginning of my LSA demo flight season :D

Don't know how old you are, but another thing to consider is ease of getting in and out of a low wing vs high wing as you and your wife get older and/or heavier.

I am in my late 40s and there is defiantly a difference , especially getting out after say 2 hour flight , between a low wing and a high wing :-)

Just wait until you're 71 and 20 pounds over-weight.

I’m 41 and wife is 40, both in fairly good shape. But I know what you’re saying. We took my mom’s boyfriend up in a PA28A a few months ago. He’s 72 and he’s a slim guy (former golfer), but he’s certainly not as nimble as he once was. It took him a while to unfold himself out of the right seat to get out onto the wing, and I could tell that it was a struggle for him - but he’s not one to complain, ever. That would certainly be a situation for a high-winger. I think we’ll be fine getting in and out of a low-wing for about 20 years, which will be perfect timing to sell our low-wing LSA, whatever that ends up being, and upgrading to a new high-wing LSA :wink:
