Height and speed are money in the bank. Never run out of both at the same time.
If you're going to go low, be fast.
If you want to be slow, go high.
And DO NOT routinely drag a SEP in on a 3 degree approach, power against drag. It's unsafe and inappropriate unless you are needing to do a performance short landing.
Low flying in the Chippy - set higher than normal power for extra speed, and trim a bit nose high so you have to hold the aeroplane down in level flight. The extra speed gives more control response and can, of course, be converted into height should the need arise. The back trim is your 'sneeze factor'; if you relax the push the aeroplane will climb away from terrain.
