Adam, Greetings from across the pond! The first time I saw one of your videos I thought you might be my long lost twin brother. I'm looking at the same solutions you are, but I'm building an ultralight airplane, so probably a bit more than twice the weight, but maybe a little less drag. Keep at it! We have kart engine builders here that can almost triple the horsepower on these engines. I also thought that with a reduction drive you're multiplying your torque too, but was sad to see you struggle. Keep it up, you're doing great! I'm still in my design phase so I envy you getting out and doing it! Thank you for being the pioneer for these industrial engines being used for flight!
Thanks for your comment. This engine was recently sold and the project finished for me. I never did quite get it to fly, however the engine is quite capable. I may revisit it in the future, and am also thinking of doing a final part video to summarise the project and lessons learned.
I found the high compression piston and 24mm carburetor made a massive difference. Also open the ports out were there is a "Step" they have terrible ports stock. 2:1 ratio works good on stock cam. power drops off feast after 6k rpm. After that she will climb well but blow head gasket every few flights. Copper gasket and oil cooler fixes this. Good luck!
@Adan M hi Adan I'm still flying this Same machine I've done around 50 hours now and it goes pretty good for a lawnmower engine! Probably about the same thrust as a top80 mabe a bit more
Maybe since a 4 stroke has more torque you can put on a higher pitched blade. A two stroke would have a difficult time getting a blade like that up to speed.
Soooo close to maintaining. Smaller drive sprocket might just allow the rpm to release slightly more power but I doubt that will be enough to allow for a reasonable climb.
Nice... Just enough power to sustain level flight by the looks of it... Soooo close :) Looking forward to seeing how the chain drive does over the longer term. I think the slop can cause Crank-Propeller resonance which may damage the crank but the clutch may help avoid it so if the clutch wears quicker than expected, you may have an idea as to why
I went for the chain as it's cheap and easy to buy the reduction you want. Although I have the facilities, I didn't want to be machining micro V pulleys. If I was doing it again however I would probably use a standard micro v belt
I am at the limit of GoKart parts, using one of the biggest clutches you can get and smallest secondary gear. I may have to machine my own drive sprocket. It may not require any changes to the reduction ratio, as I have increased the power and the results will be known soon
The engine is almost stock so possible upgrades are: Higher compression head, longer duration higher lift camshaft, advanced timing key, bigger carburettor, free flowing exhaust, bigger main jet, stiffer valve springs. Plenty to look at
Hi Adam, a great looking machine :) What size prop are you turning? Did you see any of my development and testing videos? Regards, Rob. Btw, another +3hp (7-9kg thrust) and you'll be away looking at how you almost made it :)

Hi Adam, great to see you are still playing with your paramotors. Interesting video series you have created.
Congratulation brother

I'll subscribe to your channel. Cant wait to see it really flies.
Soooo close to maintaining.

Dang..........it was looking so good!
I’ve seen these gear reduction housings that bolt right up to the motors . They have a wet clutch at 2:1 ratio on eBay.
Typical 2:1 is not quite enough but if I started again I would be tempted to try it
I have this gearbox on my trike and it works well
Nice one friend...
Can you get a bigger clutch maybe with 1 more tooth in the pinion ?
I am at the limit of GoKart parts, using one of the biggest clutches you can get and smallest secondary gear. I may have to machine my own drive sprocket. It may not require any changes to the reduction ratio, as I have increased the power and the results will be known soon
Wats the latest update bro??? And which engine u r using. I guess loncin 196cc???
Correct Loncin G200F engine. Been slow progress since this video. New update video coming soon.
How did you increase engine rpm??
Remove rpm governer, upgrade flywheel, carbourettor, valve springs
What are the plans to get more hp
The engine is almost stock so possible upgrades are: Higher compression head, longer duration higher lift camshaft, advanced timing key, bigger carburettor, free flowing exhaust, bigger main jet, stiffer valve springs. Plenty to look at
@@smad333 Hi Adam -what is the engine? Thanks.
@@acousticsoundz1985 It is a Honda GX200. Check out my series on getting to this point
Hi Adam, a great looking machine :) What size prop are you turning? Did you see any of my development and testing videos?
Regards, Rob.
Btw, another +3hp (7-9kg thrust) and you'll be away looking at how you almost made it :)
Hi Rob I am running a 1.3m prop. I have watched all your videos! Upgrades completed today ready for next test...
@@smad333 Hi Adam, excellent news. I'm looking forward to seeing the next video :)
No enough power sos!!!!!
Its heavy try to yamaha 2 strok enging 110.cc its beter then gs200.
