I bought a WG10, works well.

UPDATE Problem wasn't solved after replacing the piston rings. Finally I did a leak test and found that there was a leak in the crankcase. I first made a new paper gasket but that didn't solve the problem. Then used Loctite 5980 to seal the crankcase. Did some flights, engine is running well, max RPM is 9600, Max CHT about 175°C.

I found the problem, piston rings were worn.

Hello My HE R120 has an intermittent problem. Sometimes with full throttle, it reaches max rpm (about 9400rpm) but then rpm decreases to about 5000rpm. When i release throttle and immediatly go back to full throttle, I get max rpm. I recently changed spark plug, fuel filter, fuel lines, carb gaskets, did a carb rebuild and I use fresh fuel (2,5% ratio). Reed valves are ok. Does anyone have an idea what the problem can be? Thanks, Kevin

Taking the cover is is easy, just unscrew the bolts, but be careful you don't ruin the gasket. In my gearbox was no oil but grease (I own a HE R80 and HE120, they are boith >10 years old). I use Castrol High Temperature Grease 400GR for several years now and I have had no problems with it.

Hello My two engines (HE R80 and HE R120) have a walbro WG8 carburetor. It's getting harder to buy them and the price for a new one is very high (200€). Does anyone have experience with the walbro WG10? They are almost similar... Kevin

I Found the problem. The internal structure of the silencer was broken. Those pieces and some sound absorbing material caused a partial blockage...

Hello Thanks for the replies. Also changed the primer bulb (forgot to mention), there is a foam filter in the airbox but it's clean...

Hello A very strange thing occurs to my Vittorazi moster185. During my last flight, my max RPM just decreased to 6400rpm instead of 8400rpm. Also have a CHT gauge, max temp is +/- 205°C. Engine starts after 1-2 pulls, idles great, reaches max rpm but after about 30seconds, the rpm drops at wide open throttle. I guess there is some kind of leak when the engine gets warm. I still haven't found the cause, the things I checked and changed: - fresh fuel (2,5% oil/fuel) - new spark plug - swapped carb with a 100% working Walbro WB37 carb (pop off pressure is good, new membranes,...) - replaced the coil (with 0,45mm gap between flywheel and coil) - fuel system is ok (replaced fuel lines,fuel pump and filter) - fuel tank valve is ok - brass weight at bottom fuel tank is ok - replaced al the gaskets between carb and reed valve - reed valves are ok - replaced exhaust gasket - motor has 130h, put a new piston, piston rings, needle bearing Has enyone encountered the same problem? I am running out of ideas Best regards, Kevin

Hello I have a Canon PowershotSX730. On the ground, it is a very good camera but when I try to take pictures while flying, 99% of the pictures are not sharp. I only take my camera with me when the air is very calm. Before I take a serie of pictures, I let my engine idle. I tried several different settings for ISO, shutter speed,... but I don't manage to take good pictures. I understand that not every picture can be perfect but I want to ask with wath kind of camera some of you have good experiences. Thank you in advance Kevin

Hello, I have two HE engines. On their website you can download a list of spare parts. Just mail to ventas@heparamotores.com and you get a PI from them. I live in Belgium, delivery time is about a week.

Hello, I asked a question to some paramotor teachers: does a touch and go count as a flight or not? One said that a touch and go counts as a flight. The other said thats not true... not that it is important but I like to read your opinions. Safe flights!

Hello Andy, thxs again for your reply. Yesterday we did another flight. After two beers, the engine cooled down and we checked the tension. It was 350Hz again. Guess its ok.

Hello Andy, thank you for your reply. We tensioned the belt when the engine was cold and we waited about one hour after the flight to remeasure the belt tension.

Hello David Last week wr checked the belt tension from my friend his moster 185. it was only 150Hz. We adjusted the tension by using an app to measure the frequency, to 450Hz. After a flight (45min) we checked again after the engine had cooled down. The frequency was only 350 Hz. Does anyone know this is normal, I think not but we put nail polish on the bols and nothing had moved.
