All,
Below is a request for information that I got from Steven Hacker. So for any of you "cold weather" experts that are flying your Lightning up north or maybe out in Colorado, how do you keep the inside of the canopy clear of frost? Here in my part of Virginia, we just don't get anywhere near as cold as Steve is talking about. So, any info you provide will probably be helpful "cold weather ops" information for everyone.
Blue Skies,
Buz
Buz, I like your New Year's day flying idea but it has been quite cold here in Minnesota as of late - last night temperatures dropped to -15 F, and our projected high for today is -5 F. Otherwise flying conditions are great - smooth air and calm winds. Between pre-heating the engine canopy, battery trickle charger, and the Jabiru cold stat recommendations, I have had no problems starting my Lightning which I keep in an unheated hanger.
My problem has been on the inside of the canopy. Last week, out with my instructor at around 10:00 am with temperatures around +6 F, the inside of the canopy iced up while we taxied - and we had to work very hard to rub off the frost before we could see well enough to take off. The addition of a glaring sun did not help matters. However, once we got up in the air, between a little bit of air vent, and cabin heat, we were able to keep the canopy clear. Once we landed, the canopy started to ice up again on the inside.
Is there a trick or a compound that can be applied to the inside of the canopy? Or should I acknowledge the fact, that once temperatures start dropping below 10 F, that inside canopy icing is simply something that I need to contend with. Thanks
Stephen Hacker

Is'nt Mn. fun. I leave my side window open during taxi
Be careful to be sure it is cleared off to fly. I didn't one time thinking it would clear off better during take-off roll,which it always did before, it got worse and by the time I cleared it off I had hit fog, not fun. This happen because the Equal was out side in the rain the night before. I am only saying how stupid of a mistake I made, and for others not to do the same.
I have a muffler which gives off much more heat to the cabin than the straight pipes do. I have tried both

Almost forgot, they do make an anti-fog spray that does work well for smowmobiling, might be worth looking into
