How did you start you alternative engine project?
What did you remove from the engine?
How did you select anchor points?
How was the original throttle modified?
How difficult is it to wire all sensors, ignition and stuff to the SDS EFI?
This list goes on endless.... So where best to look for answers?
Sorry for so many questions. Hope you don't mind...
Some people are mechanically inclined, some are not. And building an experimental airplane is certainly not for someone who does not like to work with their hands and build things. Some are comfortable building a kit plane but would not think about tackling an "alternative" engine. I guess it just depends on how you are "wired".
I work hard at learning from real "been there done that" folks. We have a very active local EAA chapter here and there are a lot of folks who have built planes and were very helpful to me. I was one of about 6 guys who built RV planes in our EAA chapter. My kit was probably one of the last "no holes pre-drilled or punched" kits. I drilled, deburred, dimpled or counter sunk ever hole myself. Not bragging just sayin'.
I got my private in 1980 and I have been active in EAA for most of the past 40ish years. I have seen lots of successes and lots of failures. Truthfully there is nothing special about me but other than I try to keep an open mind to learn from both.
As far as the engine and the set up go, you mentioned the sensors and ECU. I cannot say enough good things about the SDS EFI and the over 2 decades of support that Ross and Barry have provided. Truly unparalled support. The system just makes the set up programming of the ignition and injection systems easy.
Back to the engine. There are a lot of great engines out there. You just need to figure out which one that has the right power, weight, and history of longevity that works for your set up. And find a PSRU / reduction drive gearbox that is appropriately sized and shaped (offset) that you need. This can be more difficult than the choice for the engine.
I hope that answers some of your questions, hope so.
Time will tell about my set up, it is too early to call this a success . I feel good about the progress but the proof will be in how well it turns out in the end, and that is still a ways off. We shall see.....
