I grew up riding 2 stroke dirt bikes in the desert. They seem very prone to seizing up, overheating, melting pistons, etc. I guess the power to weight trade off is worth it for paramotoring, but I'm surprised there hasn't been a lot of 4 stroke motor development for paramotors. Maybe they are just too heavy?
Its mostly the power and weight. There are a few four stroke engines out there - Bailey and Blackhawk make versions - but they don't make nearly as much power as two strokes of the same size and weigh more. I think the other aspect of it is the simplicity of two strokes. Two stroke engines really don't have that many moving parts and fixing them is pretty easy. You also don't have to worry about oil leaks or oil levels.
@@shannonwhitaker9630 I'm assuming its the EOS Quattro that he's going to be flying and I don't really have an opinion on it. Its way too big for what I need.
@@shannonwhitaker9630 I got it from the Miniplane distributor in the states. With shipping they're under 3k. I went with the Top80 as I have propellers, spare parts and have worked on them extensively. Yes I could have done an Atom 80, or even a Polini 80 but I'll stick to what I have parts and knowledge on.
Thanks for the info. I’ve been trying to learn about the Top 80 and Atom 80 for a non-Paramotor application. The engine will be used in a tractor configuration. I don’t know if the gearboxes/reduction drives are robust enough or even capable of withstanding it.

What do you think of the EOS 4-stroke that Tucker is about to start flying ?

Dang. That's a bummer. Nice calm and controlled free glide in though. Hope you get the motor sorted out and back in the sky soon!
Should have a new motor by this weekend and be back in the air soon.
Where did you get a new Top 80 and what do they run ? Maybe it’s time for an Atom 80 or are they more expensive ?
