skyfox99 Posted March 24, 2013 Posted March 24, 2013 Hello, I have been looking at a Tecnam P92 Echo with a Rotax 80hp. They say its cruise speed is 95knots. Would this be correct IAS at 5000rpm? Fuel burn of 14ltrs per hour? There dosen't seem to be a lot of performance difference between the Rotax 100 vs 80hp. Would like thoughts from those who have flown these aircraft. The Tecnam seems like a great aircraft. Thanks you in advance....
facthunter Posted March 24, 2013 Posted March 24, 2013 The bigger motor will get you airborne quicker on a hot day and give you a greater ability to get higher. Nev

Skyfox99, I would say that would be pretty close, my Sierra does 95kts at about 4800 burning about 17lph, balls to the wall 115Kts on about 24lph. Your correct they are a great aircraft, beautiful build quality from what I have seen on mine and lovely flying qualities. Cheers Alf

The Tecnam seems like a great aircraft. Thanks you in advance.... I've flown a 80 hp Echo and yes figures are correct. As already stated their climb performance won't be as good. Build quality and design is second to none however I am a little biased. Very well balanced controls with excellent feedback. Willborne.
paulh Posted March 24, 2013 Posted March 24, 2013 Flown a bit in Echo's and a Sierra, the Echo with those long wings is slower than a Sierra with the laminar flow airfoil but in my limited experience the Echo has safe forgiving handling, nice balanced controls, positive control response, good short field ability, tough undercarriage. The seating position puts the pilots sight line up near the wing root so visibility upwards to the side is restricted a bit by the wing root, need to duck your head a bit to have a good look. A nice well built aircraft. A 100hp Echo is happy at 95kts IAS 5000rpm
skyfox99 Posted March 25, 2013 Author Posted March 25, 2013 Thanks for replys, trying to get a feel for the aircraft performance. I like the fuel burn of the 80hp compared to the 100. Looks like the 80 has similar cruise to the 100 but lacks in climb.
facthunter Posted March 25, 2013 Posted March 25, 2013 You don't have to use high power in cruise and the lower power setting on the bigger motor may not be not so different infuel flow . A draggy ( Not that this is particularly so) plane pulled along fast with exces power is a waste of fuel. If you are high altitude or short strip the bigger engine would help. Nev
skyfox99 Posted March 25, 2013 Author Posted March 25, 2013 Thats a good point actually, we very easily get fixated in aviation. Like it has to be...can lead to trouble. We so have to keep our minds open at all times.
