the first plane i learned to fly with was a sig piper cub and to this day i still have a cub in the hanger would never go without one but i've bought my share of trainer aircraft for cheap beaters the best one to date was and old 40 size arf off of ebay for 40 bucks i put in some gear i had laying around. That had to be one of fun flying aircraft and it was oh so forgiving until the metal clevis on the elevator broke and it turned into diced airplane as it went thru some trees at almost full throttle (one of thee most amazing crashes i've seen in person to date). I now have a PT-40 (off ebay for 45 bucks) but its highly modified it has an OS 61 FX i flattened the wing added an extra servo to the wing, bolts instead of rubber bands and shear webs in the wing doubled all the surface sizes and it's no longer a trike gear to help with the bigger prop its just another fun slap in down and fly the crap out of it plane and by the way my cub has an OS 120 Gemini twin on it looks and sounds great
