Bob- I agree- its fun AND pretty to do scaleish takeoffs. Not my old habit, but I'm trying to make it my new one. Its alsoa lot betterto be taking off level(er) if the engine quits, eh? BTW- Have youevermanaged to land on the mains and roll 20' before the tail hits yet? I'm wondering if its the nose high attitude when you slow it down that is making this tough for me- all of my clean landings are ~3 pointers.Probably justmy "new plane" jitters, but I'm having a hard time- maybe I'll up the airbrakes from 13-20mm &amp; see. Of course thehigh wing layout on the Cub probably makes it easier for my buddy- you can see the darn wheels better! (Oh, yeah he's a better pilot, too! That'll all have to be next weekend- we are flying off water both days this weekend and my Phoenix Extra (Phextra?) isn't due for such "carnage by the sea" abuse til NEXT year...!</p>

Racerchuck- FYI: I found 8-32 nylon bolts (not 5/16) went into the existing canopy blind nuts nicely, meaning a little "squeaky'. The blind nuts are 4mm dia by 0.7mm pitch which is close enough to the 8-32 diameter (0.164" dia) that it works. In fact, the 8-32 is only7 thousandths of an inch bigger than 5mm (0.157" dia) and the 4mm nut isalways a hair over 4mm and 8-32 bolts are always ahair under 0.164" making for a nice tight fit in most cases. The slight difference in pitch on the threads (32 tpi vs 0.7mm pitch) actually HELPS because it makes them turn in a little hard but they don't vibrate out. The 8-32 starts nicely and tightens up ina turn or two because the 8-32 pitch in metric would be 0.79mm vs 0.7. So for each thread engaged you get 0.0036")of interference in pitch added. This is good for short thread engagements- after about 8 threads you've actually wiped a whole thread out. OK, so maybe I do a little too much with threads at work....simply put, by dumb luckit works great- couldn't have designed it betterif Itried! Just go easy with the screwdriver the first coupla times when you put them in (torqueis high at first)or you can stab a hole in your fuse!! There are a few happy coincidences in the whole english/metric mess. Another one is the 5/16-18 vs M8x1.25- so close that you can squeak them together for lightly loaded applications like nylon bolts. Be careful doing this in metal, though.... the threads will pull out easier with the pitch mismatch.</p>

Ace Hardware has the 8-32 screws in nylon for flat screwdrivers. Next, I am looking for hex head nylon 8-32 to reduce the stabbing! I found the real 4mm x 0.7 nylonpan head screws at the hobby shop and will try them on the gear..... because those are loaded a bit moreI was a little nervous about the 8-32 trick- I can drill and lockwire those or just reef on them to keep em tight.. Another 0.3 oz saved for a buck or two!! Ihave had bad luck with the nylon screws in colder weather- but that's not til October....</p>
