I am very surprised that you would loose control when only one flaperon is connected to your stick instead of two. In my manual Avid states that you can control roll (if flaperons are completely u/s or disconnected) with rudder only. In the above scenario he still had one flaperon working + rudder!!! Any thoughts?
If I was to choose a new engine I would go for the BMW R1200 engine. Parts are a non issue at a reasonable price. Here you have some info about a guy fitting it to a cherry BX-2.. http://spang-air.de/e/html/bmw_-_engine.html
Price wise you can get them at a good price too... https://www.ebay-kleinanzeigen.de/s-anzeige/bmw-1200gs-flugmotor-m-neuen-bleidieselgetriebe/687835651-242-5976

Hey Curt, I understand you're at a high elevation and have not much useful load there....but looking a little further down the road, if one day you sell or the plane moves closer to sea level it is of GREAT value to have the possibility to fill more fuel.......One of the prime items a buyer is looking at is endurance . I bought an Avid with 14 Gallons (only one tank in the right wing) and lowered the price because it takes a LOT of work cutting into the wing to ad another tank. I am very limited in range until I add the second tank because the Avid flyer fuel pick up is far from ideal. 4-5 gal in the wing tank is not enough to fly safe as you will constantly feed from your header when banking/climbing & descending...
Hey Allen, thanks for your input. My quote about 2smokes has nothing to do about them being good or bad....it's only financial! A 912 s is many times the price of a 582...so logically an amphibian fitted with a 912 is more expensive than when fitted with a 582. This amphibian is fitted with a 582 and basic instruments (handheld VHF, no xponder) . hence my comment. 2 years ago I bought a very well built Catalina (evolution from the amphibian) fitted with a Rotax 912, in flight adjustable prop, panel mounted VHF and transponder with a purpose built trailer for 27'000.... Also not so long ago a complete catalina Kit was sold for 7500US.. My 2 cents....
Found this ad on barnstormers.....I wonder why someone would install wing fences on an avid amphibian? Price is quite high being fitted with the 2smoke I find. https://www.barnstormers.com/cat.php?mode=search
Hey , I am just wondering what impedance is best with the 912. Some caps are 1kΩ and the ones you bought are 5 kΩ.... I found this company selling caps for the 912 and they're 1 kΩ.... https://shop.brp-rotax.fr/en/all-rotax/12667-983409-shielded-spark-plug-connector-bosch.html
one guy (courierguy) on backcountrypilot.org forum has more than a 1000Hrs on the big bore kit without any trouble... Over a one year period now I have NOT been able to find a single failure story regarding the big bore kit on the net anywhere. I am REALLY interested in the complete story of the guys having had trouble. Why is there nothing about their misfortune anywhere? It would be very helpful of you to bring these stories to light for the rest of us. In the meantime I am going to ask Hall if he knows more about this. Thanks for your feedback P.s. It is very helpfull to have the details like: Were the engines converted from 80Hp to ? Hp or did they use 100uls engines to go higher Hp / did they install fuel injection,turbo,high performance camshaft? / Were the engines old, used, prop strike before mod etc...
Hey Ljones I have not heard of any 912 fitted with a big bore kit "blow" up..... Can you please give more info about you having watched 3 blow up!!!!!!!!! where, what aircraft, Hrs run, which model 912 etc....
Regarding the pitch setting on his 912s it seems he is way over pitched and overloads the poor 912... He's only getting 5100-5130Rpm WOT on take - off / climb (you should NEVER run below 5200RPM WOT.... Should be at least 5350+ Level WOT he is only getting 5390Rpm.....should be at least 5500 to 5700Rpm.
The 912 really likes to cruise (~75%) at around 5200-5300Rpm for best efficiency. If I were in the market for a Kitfox 5 , would not buy this Kitfox (even though it looks great) because of the risk of the engine crankcase fretting ......it's expensive to fix....been there
Hey Allen, I have flown extensively in europe and found when I flew there I had always somewhere I could land if sh*** hit the fan (meadows, river creeks, lake shores, valley in high mountains, corn fields, lots of airfields, etc) . When I started flying a C-172 on wheels here in Canada (british columbia) it was the first place I found I often had no place to go if my engine quit.....(big rocks, big forrests and ocean/lakes) I did not feel comfortable and decided to go "amphibious"....what a blast. There has not been a single flight where I did not have some water to land on . I now fly mostly in remote places and my Catalina may see a runway 5% of the time......I really feel good and safe to be able to drop into a 500feet pond if needed... Just my 2 cents..
Hey northidahoflyer, looks great. There is just one gauge in your cockpit I would reposition If I were flying your nice bird...I would swap the VSI with your ASI so that when you're landing for example your eyes have a shorter distance to look between outside and the ASI for that quick speed check on very short final.. Just my 2 cents
Hey Eg, on my 912 I had the same and found the choke lever return springs too weak, the chokes were not resting on their "off" position properly. Also make sure your floats are good (guess you checked that). One more item is the ignition leads which might not be properly inserted/screwed in their respective coil and spark plug cap. Check the float chamber vent tube, it should be installed so as to be at the same pressure than the intake (do you have an airbox) and if it's in the airstream (low or high press) you'll get rough running. Another easy item to mount backwards in the carb is the diffuser..item#2 https://www.cps-parts.com/catalog/rtxpages/914bingconstant.php
Regarding the mag drop my 912 is the same and I would not worry about that. My 2 cents
