With regard to climb out speeds, get your hands on your aircraft Pilots Operating Handbook and check out the various performance speeds. I think you'll find that the best climb out speed for a PA28 161 is 79kts clean and 63kts best ROC. Of course its also config dependent. I find that if doing a short field departure with flaps 25deg set for t/o on a PA28, 50kts rotate and then 65kts initial climb speed gets you a very impressive rate of performance (off the deck in no time and good ROC) En route climb speed is quoted at 87kts. Some schools will seemingly quote t-off and landing speeds in various configs that are a bit higher than the P.O.H. This can create problems in itself tho' as a higher than recommended approach speed in full flap config on something like a Warrior is going to create more float and a longer landing roll - not good on a short field!!!!
