"Hi Ken. I just sent you an email."
"Thanks for the advice. I will cut the long pipe, add gussets and prepare for later this year get the new muffler."
Hi folks.
I had a cracked muffler on my 110 engine after 50 hours of operation and soldered it back over the crack. Anyone else of the Viking 110 guys had this issue?

"Hi Idrise. Congratulations for your choice of building a Vans RV-9. It is a great airplane. As you can see, it accepts a wide margin of engines: from 118hp (prototype) up to 160hp according to Vans website. I am in the lowest side of the power range…"
"Great idea. Saving some $ for upgrade."
This is a Viking 110 RV-9A with Phase 1 completed. First flight was little more than a year ago: Feb. 4, 2016.
Charts show max TAS of 146 mph so far. 400 miles leg takes 1/2 tank of mogas with 25% of ethanol (this is Brazil...).
update on Jun 23,…

"Hi Tom & Jim. I have only 40 minutes of flight after the new Right Stuff sealant applied between the tank upper edge and the top plate. So far I did not have any leaking. In my knowledge, the Right Stuff replaces any o-ring or gasket, so you use one…"

"Thank you DS. My airport is at 3,300 ft elevation. My static rpm is 4,800. Takeoff run 0 to 60 mph is in 13 seconds. Initial climb rate at 80 mph is 950 ft/min. From 3,300 to 12,000ft it took 18 minutes."

Hi Heliano. Send me your email.
Hello, Jose! Where are you in Brazil? I have a few questions I'd like to ask you about your experience with importing and installing a Viking engine. I am currently in Campinas area, and am planning on importing a Viking 130 next april.
Hi Idrise. Congratulations for your choice of building a Vans RV-9. It is a great airplane. As you can see, it accepts a wide margin of engines: from 118hp (prototype) up to 160hp according to Vans website. I am in the lowest side of the power range. As Jan said, my engine is a Viking 110. It provides a maximum of 110 hp, but performance is nice. Takeoff numbers are very good. At 5,300 ft density altitude I reach takeoff in 800 ft and climb at 1,000 ft/min at Vy of 86 mph. Max cruise is around 150 mph with autogas. If I want to cruise at 12,000 ft I have 120 KTAS at 5.0 gph, it will give me an endurance of 7 hours. As you said, I still can increase my top speeds around 10 mph with better cowling and new Viking 110 muffler. I am curious to see a flying RV-9A with a Lyc. O-235 (118 hp) cruising at 163 mph as Vans site states. Notice that I have a light aircraft as well. My empty weight is only 920lb. which puts the CG to the aft side of things. Remember that I don´t have the "normal" 300 lbs in the nose which is the installed weight of a Lyc. IO-320
but only 200lbs of a Viking 110, so I am careful not to put 75 lbs in the baggage area which is the Vans number. Now if I went for the price, a top XIO-320 would cost me $ 28,000 plus firewall forward of $ 5,000 plus C/S prop $ 7,000 etc... totaling $ 40,000 FOB. It is scary. If I were at your stage I would think about a Viking 150 turbo and the adaptations involved. That would be nice. Good luck! José Almeida.
Jose has a 110 hp engine in his 9. Not a 135 hp engine
Congrats on completing your RV-9 and installing the Viking power plant!
I'm about halfway with my RV-9 airframe and starting to look at engines. Vans published performance numbers for the RV-9 seem to be significantly different for 135 HP from what you're reporting. Even with a 118 HP Lycoming, it should be topping out near 170. Of course speed isn't everything, but I'm curious why there's such a significant difference. Do you think your engine and propellor combination isn't developing comparable thrust? Perhaps the Viking specific cowling and cooling inlets are increasing drag? What are your thoughts? Thanks!

Wow! Maravilha! Então perdi para você a posição de ser o primeiro cliente que voa Viking no Brasil. Estou enfrentando atrasos por causa dos adaptadores do berço Dynafocal tipo 1 para o backplate do Viking. Como seu berço já é preparado para o Rotax 912, presumo que sua instalação deve ter sido mais fácil. Vamos manter contato.

Wow! Wonderful! Then I lost the position of being the first Viking flying customer in Brasil. I am facing delays because of the Dynafocal type 1 adaptors to Viking backplate. Because your engine mount is already prepared to Rotax 912, I presume your installation was easier. Let us keep in touch.
