Thanks for the info guys. The more I learn about this, the more I need to learn. Another question, if I were to buy a used ultralight. How does the insurance work? Is it liability, or does it cover the aircraft, the pilot, or all of those? If buying used are there ways to have a mechanic do a routine check for signs of trouble, I realize there is no sure fire way, but just a reasonable check? Would there be registration requirements? I am going to try to visit the Kolb place in a few weeks. I know I will come home a bit sad because I won't be able to afford a new one. I will be for me like visiting my favorite guitar shop and leaving empty handed. Hey but I'm goin anyhow. Thanks David

May have been you mentioned that before. I talked to a local guy who says the same thing. I think I have learnt that proper rpm and loading while flying control the mixture and heating. It seems like there are two speeds that they run in. A high idle or wide open? I have done quite a bit of reading, but must be missing something. I don't think I understand, say a sequence of throttle events of a flight, relative to temp control. In a 150 I would in different maneuvers use all the speeds in the green arc, and idle with carb heat on some. Could you explain an example of throttle settings during something like lazy eights, and or a power off stall. I'm not understanding how you manage the head/piston metal exchange of heat. When I watch utoob it seems like the work the throttle a lot on touch and go's. How is that? I'm sorry I don't know correct terms for some of this.

Yes, I seen that one. Very cool! I'm still learning, but are those LS? I don't know anything about ownership. How is this different than owning an ultralight? Registration insurance etc.

I have been home for a couple of weeks recovering from a back problem. Doing a lot of reading and thinking. I have a ppl but job changes and such not enough to money to fly. I'm kinda eyeing a firefly, but am a little concerned about a two stroke. Does anyone know if there is a 4 stroke that would work on the firefly. I live in western Ky, probably less than an hour by air to where the kolbs are made. When the runway drys up I'm gonna try to fly there. Just want to have some ideas to take with me.

Wow, very good reaction and level head. I hope I could keep as calm as you did.

New guy here. I am a private pilot, not current now but planning to get back into it soon, like in a few weeks. I have been considering an ultralight. I keep coming back to the Kolb firefly. I want something I can keep at home and is quick to get in the air. I have been reading a lot about the 2 cycle engines. Seems like the more you read the more you see the distance of the 2 vs 4 stroke people. While I agree the 4s are most reliable the fact still remains that the choices are very limited if I want to stay light and fly, and maintain cheaply. I have emailed several Kolb owners selling them that say they have flown several years on their 2 stroke engines. I would be interested to hear from some of your experiences of your 2 strokes, that were operated properly and lasted a good while. Thanks David
