A density altitude of 1300ft does not seem to be a particular issue.
Having said that I recall my old Terrier hated the heat - once the temperature got over 30 degree C it would skip along a runway for quite a way and then reluctantly climb away - 500 odd metres was always plenty but with a shorter wing who knows?
My Terrier had a pretty comprehensive set of data on takeoff and climb performance in the flight manual which would answer the question on likely performance (even though it had no fuel or oil consumption data!)

That is a very cruel thing to say.
Provoked by simply jealously I think - a Terrifier beats the air (and small obstacles) into submission, your lightweight machines are simply windblown seeds in comparison.
That day we were at the full 2400lbs in nil wind and used virtually all of the runway at Lognes - but there is something mighty fine about flying down the Seine low level in blazing sunshine with your elbow out of the sliding window!!!

I have to confess to being the owner of a Terrifier!!! In fact about to go and beat the air into submission before dark. After a day flying IAP's at work I need the simpler things in life!!
I must confess to raising an eyebrow as to density altitude being the cause of this incident. My experience with DA was on a midday takeoff in a PA-28 140 with 3 on board at Nairobi Wilson in a temperature of 32 degrees C. Full tanks of course. It was a VERY long takeoff and it was only afterwards that we worked out the DA was up near 8,500 feet. You start at an actual height of 5,500 feet above sea-level of course. The only redeeming feature was that a Lufthansa crew with 4 pax went through the fence in a PA-28 Arrow a couple of weeks later. Nobody hurt fortunately.
Many years later I was in a group on a Cessna 172 at Denham and having flown and filled her up, one of the other group memebers plus 3 friends and bags were about to depart to the IOW. It was quite a warm day so I asked if they'd checked the DA and they looked at me as though I was barmy but once again they only JUST got off so DA can bite in the UK.

If you routinely fly a 4 seater - well yes. Because usually we only fly them 2 up.
My friend used to lend me his TriPacer - very capable machine - especially when light - close to Super Cub performance at low density altitude and weights.
Put full fuel and 3 fat b**gers in it - the performance change was considerable. So yes, unless you routinely fly your aircraft at max weight then it is easy to be surprised by a somewhat sluggish 'leap into the air'
The Terrier being a monstrously heavy beast had much less of a change in performance - but then its power to weight ration would never impress!
