http://www.tflighttech.com/products/airborg-h8-10k-with-top-flight-hybrid-power-system.html might be best option on the market for long distance flights currently if the engine requires too high of RPM then it will be high maintenance.

NEW RCGF 20cc RE-Stinger

Some things i’ve found to be interesting related to hobby flight.

CCRCSIM — opensource rc flight sim

UMX AS3X beast foam plane — these things take a s@it kicking and you can just hotglue them back together. the downside would be the cost ( 200 for remote 200 for plane) upside the remote stores settings for 6 planes and its uses plug and bind to make setup easy. also use tape to reinforce the tail, center wing supports and along the leading edge

https://www.horizonhobby.com sells umx biplanes for about 170 CAD.

foamboard can make great custom planes for a couple dollars.

great toy thats very durable are the mini pet quadcopters for 40-60 dollars with remote. depending on what version you get the controls can be pretty funky. will try to get some links to the good ones soon. 500 mah batteries last longer than 10 min flights. also larger 998 version will take wind better these little bee’s are for indoors or calm days.

AR500 SportsCraft 5 Channel Transceiver – to work with dx6 remote
Turnigy 2204-14t motors $15 dollars each with turnigy esc  , Motor bases were larger so i used wire to secure them to one side of base might add more loops later.
850 mah battery 20c 7.4v – not sure if it’ll work for this yet.
Had purchased 7035 propellers but was unable to find opposite pairs so I’ll need to print some tri blades with a few less mm to avoid tip rubbing.

 

This engine could probably spin 3 or more of those motors to generate more than 100 Watts. possibly needing gearing + flywheel.
