Photo above shows the left lower wing buck painted and polished ready for a mould to be taken off. Will start making patterns for this and cutting prepreg this...
We got an elevator trim tab half and an elevator aero balance half laid up this weekend, pic above is of the aero balance, attaches to the end of an elevator....
David, Any idea what the engine maintenance and inspection recommendations will be like? For example, in my short research on the topic, some feel that the...
I wouldn't think the cylinders would crack, but the issue with the cylinders is that the large bore diameter reduces the cooling flow between the liners....
Do you mean Glycol? Still partial to plain old Prestone, and won't go near GM's Dexcool as it seems to be responsible for some corrosion and leak problems on a...
It's propylene glyclol and some more additives instead of ethylene glycol (normal antifreeze.) More info here: http://www.evanscooling.com/html/npgPls.htm ...
I have heard nothing but good stuff about NPG+ in the automotive world - when it is used correctly. There can be no water in the cooling system at all for...
The Down side of NPG is that it doesn't readily transfer heat as fast as pure water, sorta like oil. Some have tried it in other areas only to find that the...
Sounds like we should stick with basic antifreeze then. The stuff has been proven over millions of miles, and altitude has no effect with a coolant system as...
There is a plan for winglets, but not right now. I have been working with Gary Robinson, original designer of the CompAir, over a few aero related thoughts....
Speaking of CompAir, any thoughts on their design. Anyone ever flown one? I was interested in a 4 seater with some short field performance, but I can't find...
Dave, Your elliptical wing design is not only the optimum aerodynamic shape, it is also the optimum structural shape. Adding winglets would put a bending...
Dave, I concur with Ty. Many years of flying aircraft with and without winglets exposed me to some interesting discussions on the subject. When checking out...
Design has a relatively high aspect ratio of 8.85:1 and the wing loading calculates to be 23lbs/SqFt, lower than originally designed, so should be a good high...
Of course the real answer is, as usual, more power. That Chev engine can easily stand more capacity and more boost so long as you cool it right. Rather than ...
Well, the answer can be more power, but I'd rather it be less drag if possible. Would really like to keep the engine from making too much more than 300 hp for...
... With a crate engine costing $3,000-5,000 and a comparable certified engine costing in the range of $75,000, one could change their overworked LS at every...
In any case I'll try to keep the prototype's engine turned down to minimums to find out how long one of these will last. I'd like to put an end to the...
TBO in the aircraft world means it is ok to replace anything that unbolts from the case if it frags prior to the stated TBO and many times barrels or valves...
What about the option to supercharge and run higher torque numbers at a lower RPM? I typically use my airplane for longer trips and would prefer a quieter...
To me, removing anything from the engine more major than a valve cover or oil pan is getting into engine rebuild. To replace cylinders is engine rebuild in the...
I do agree that boost is, within reason, easier on an engine than revs. To say supercharger, you mean an engine driven blower I assume. I am against blowers on...
I just got Car and Driver magazine for Jan '07, page 63 has an article on the LP1 similar to the Hot Rod one earlier this year. Yet another car magazine...
For those of you who read Kitplanes, this will be redundant. Barnaby Wainfan, a principle aerodynamic design engineer for Northrop Grumman, writes an article...
Another point.. If you compare the best engineered engine driven supercharger installation against the best installed turbocharger installation (all else being...
A supercharger can be packaged reasonably well, but it takes a custom setup to do it; you have to either direct drive the blower off the crank or belt drive...
