I weight about 100Kg naked. Consumption is average, about the same as for Simonini mini 2 plus. Actually I have not registered any major issues with this engine, except maybe on earlier models (up to 2007) the upper part of the exhaust system (silencer) did need some attention or repairing after not to many hours. That is sorted out on newer models.

I have owned a number of F200 engines and my present paramotor with trike undercarriage has a F 200 engine and I have always been very satisfied and impressed with this engine. Think I have well over 300 hours paramotoring with the Czech manufactured F 200 engine. I have never owned a P.A.P. frame though so cannot share any expirences there.

I am using this premixed gasoline /oil for years with only good experiences. It is premixed with 2% fully synthetic oil it can be stored premixed for at least 3 years it does not smell like regular gas (inside your car or luggage compartment) if spilled it does not attack rubber etc in the same way as regular gasoline. It leaves a minimum carbon deposits and the sylinder always looks great (no small scratces etc inside) P.S. I do not sell this product or have any comersial interest in it. http://www.aspen.se/Aspen_%28eng%29/Consumer

Today I tightened the reduction belt and also used some belt spray on it. Started up the engine and at least from the ground test it seemed like the engine has got back its thrust and the engine sounds normal. Howewer the tachometer RPM climbes up to approx 6000 rpm and then starts dropping even though i increase throttle and engine revs up more. The tachometer drops to about 4500 RPM at full throttle. I replased the tacho with another tacho and gess what the tacho nr 2 works normal and show 7850 RPM at full throttle. So I still have to do a flight test to be sure that all the thrust is back and maybe the conclusion could be two faults at the same time the tension of the reduction belt and a faulty tacho? Milan.

Yesterday I went off to my regular starting place. I started my engine F 200 in trike configuration. The engine started well and run good , but when I applied full power i noticed considarable less thrust than normal and a slight change from normal in the engine noise. At first i was sure the belt was slipping , but i think it is good tensioned so i was a bit suprised. Howewer when i looked at my RPM gauge it show a considarable and sudden drop in rpm at full speed from about 6500RPM (max RPM on this engine used to be and should be 7900RPM) when i apply more power the RPM on the tachometer show a drop to about 4000RPM, but the engine does not sound at all like dropping in RPM it just makes a slightly different noise and has not full thrust. The RPM gauge as you know is picking up the rews from the spark plug. How do I explain slipping of the reduction belt if RPM drops instead of increasing? Could this be a ignition problem? The engine runs wery well on idle and in mid range and starts good. Of course all the settings on the carburator is checked out H and L. Please help anyone? Milan.
