===============================Hi,
As the title says, me and a group of friends are looking for advice on how we could power a small ultralight 1 seater aircraft we plan on building. This plane would not be going from airport to airport and never taken more than 500ft up, it is simply for field hopping. Unfortunately we are based in the UK so both our choice of parts is limited and we only have a budget of around £800 (for the engine). We have looked at small horizontal engines up to 25Hp as it seems the only way to obtain a reasonable amount of power cheaply (how we would go about attaching a propeller will likely be improvised) however if anyone knows of any cheaper solutions or would like to offer us any advice on completely from scratch builds - then it is incredibly welcome.
$800 GBP = $1,065.15 USD.
What Plane you looking at and what is its MTOW?
Your best bet is to buy a Good Used Rotax 277UL with a Gear Drive, 28hp@6400rpm. They were also rated 26hp@6250rpm. Used they can go from $250 to $600. A complete rebuild kit on eBay is $140. The Skidoo Snowmobile 277F/300F Engine is the same Engine, but can only use a Belt Drive. ACE Belt Drives might be able to help you out with a Belt Drive. Scat Hover Craft also used the 277UL. UL version has an O-Ring groove around the PTO, the Snowmobile version doesn't. Could it be adapted, yes. There was a guy just 2-3 weeks ago on FaceBook Marketplace that had (4) Sled 277F's for $100 each. Complete, Engine, Redrive, Exhaust, their 65 lbs.
