All things equal (CC, Rpm, CR, Etc) Two stokes will not make twice the Hp of four strokes.==============================
Take the same CC, 2 & 4 Stroke Engines and turn them the same rpm, the 2 Stroke will make double the hp, so yea it burns more Gas
That's a lot of assumptions in a single post. You are obviously an angry boomer (who else would still use search tempest?) that is only here for forum sliding. Begone troll.===================
What makes you think I'm mad? Maybe I get a little frustrated at times, never mad. We see People daily come on these different FB Groups and on here wanting people to do their research when a simple Google Search would answer 95% of their Questions. Like Quick Heads FAQ FAQ I gave you a link to would Answer most of your questions!
Looking for a Plane/Project you would look in the Wanted Section on here, or Barnstormers, or eBay, or FB Market Place, and Craigslist and I use www.searchtempest.com which is a Good Search Engine for both eBay & Craigslist. In 15 Minutes you can search in a 2000+ Mile Radius of where you live from your Zip Code.
Not understanding something is one thing, being Lazy and not doing some research is another. You ask one thing, then say another. It's obvious you haven't really researched this plane much or the different engines used on it. You could have said at the very beginning, Hey, I'm looking for Flying Quickey Q1 with a 4 Stroke or a nearly finished project! If you had done some basic research on Quick Heads you would find very few Q1 even uses a 4 Stroke Onan 18-22hp, because it's underpowered, let alone any other 4 Strokes which are usually too Heavy, until today, there are some Honda/Clones that could work. The Plans/Kit came out in 1978 that's 43 Years ago.
The Build Time for a Quickie Q1 is 500hrs/8hrs= 62.5 Days at 8hrs a day, or 31.25 Weekends. The fastest one built I know of was 6 months and that was 25 years ago. Today with Hobby CNC Routers, 3D Printers, premade parts you could do it in less time. Since 3D Printers have gotten larger, you might be able to 3D many parts. I have seen a 20ft Kayak 3D Printed in modules that were then glued & screwed together.
It's like Victor putting down 2 Strokes left & right in his post, then recommending a 2 Stroke Polini, kind of ridiculous, isn't it?
If you want to Learn about 2 Strokes, Download and Read this Book. It's Free.
Lol, search tempest was great before they got sued. The old standard of using: site:craigslist.org [search term] into your search engine will give you results without the ads. It isn't geo limited.THREAD DRIFT ALERT
As a Boomer who just recently discovered Search Tempest, is there a better tool out there?
THREAD DRIFT THREAT OVER !!!!
======================Armilite I'm not the one looking for a Quickie, 1bad88 was the one doing that. The Q-1is small and light enough that using a much lighter engine on it (a 2-stroke that weighs less for the same HP) would create significant balance issues, which would complicate the conversion.
As for me personally...
I can look up things in a book as well as anyone here. I can even understand most of the things in most of the books (for the books I can't understand, Billski, Dana, and three or four others here can translate it into simple words that I can understand).
I appreciate 2-stroke engines but I also appreciate their limitations and their window of real-world use (I am sorry to have to be the one to inform you, but the 2-stroke Rotax engine does not cure cancer. No matter how many exclamation points surround it).

No need to further pollute 1BAD88's Want ad for a Quickie project with unrelated motor discussions.
Start a new thread in the 2-stroke section and we can discuss the common sense scientific reasons why double hp will not happen.
Like I said not going to pollute 1bad88's want ad explaining two stoke vs 4 stroke operation.========================
Start your own thread and Prove your Point, 670 Skidoo vs a 670 V Twin! Same CC, use the same rpm, same CR, same Carb CFM Size, etc.
