An RV-8A crashed yesterday in Rochester Indiana - N44RX. From description it appears the weather was a factor. See http://www.wndu.com/news/022005/news_40109.php

I am interested in flying to Canada from US in my experimental (after winter). Two questions. 1. I already got a copy of Transport Canada "STANDARDISED VALIDATION OF A SPECIAL AIRWORTHINESS CERTIFICATE - EXPERIMENTAL,....." permit. But section 9 says "except when otherwise directed by Air...

One known problem is that aircraft engines turn CCW looking at the prop but auto alternators have cooling fins optimized for CW. But thats not apparently as much a problem as the pulley nut potentially comming loose. For CW rotation the engine torque will tend to tighten the pulley nut but for CCW...

Looking for a ready made 13VDC electronic switch, that switches a circuit on when voltage reaches 13+VDC - or a simple circuit. It would be for optional devices I want to go on when the engine is charging and off when not charging. Any sources? Not sure what to Google...

This thread is not about how to balance a prop or shop balancing machines. Did anyone use BalanceMasters device bolted on their ultralight prop? These devices apparently balance the prop continuously as you fly. Similar devices are used on truck wheels - see www.BalanceMasters.com and...

Its not much flying time around here in SD with temps averaging 0F. I got my engine (Franklin 6) apart trying to cure a vibration problem (0.4 IPS) - not extreme but anoying. Is it OK to balance the crank in a automobile machine shop or are there some tricky things about aircraft cranks? I know...

I got a IVO magnum prop in-flight adjustable - no spinner. Did anyone do a dynamic balance on one of these? ------------------------------------------------------------------------------------------------------------------ SQ2000 canard http://www.abri.com/sq2000

Just a warning for those who might consider purchasing Rapco dry vacuum pumps. Make sure that your engine does not leak oil. If there is any chance of an oil drip onto the Rapco vacuum pump it may eventually stop working. The connecting shaft is vented to air. But if some oil drops on the shaft it...

In some instances I have had refusal to sell me parts from general vendors if I tell them it was for aircraft use. One refused to sell me a 1000lb digital weigh scale and another mfg refused to sell me a suspension spring. They don't understand the difference between certified and experimental...

At higher altitudes (non-turbo piston engine) is it more efficient for power/economy to use medium or max RPM? There is much less air there and if the RPM is too high will it be starving more than at lower RPM?

Hi, Just returned from Oshkosh home to Pierre SD. I filled up at Dodge Center MN this AM and not being familiar with the self serve gas fillup, I did not hang up the pump handle properly. Somebody after me continued pumping another $150 on my credit card ($200 instead of about $50). My...

I am planning to fly in Monday (to Wed) and tent there on EAA campground. Can a camping spot be shared by two+ tents? Anybody interested contact me: http://www.abri.com/sq2000

Anybody know a source for metric brass screws for the Microair transponder? The ones that came with it are steel and I need to cut down on magnetic interference. I think they are 12mm x 4mm dia x 0.8mm pitch.

I sold my mechanical Ruggles weigh scales and now am trying some digital automotive racing scales that are just a little more expensive. The scales I found are actually less expensive than normal racing scales but the real advantage is that they can be sold individually rather than a set of four....

When talking radio trafic in Canada how do you designate your "experimental" aircraft. In US you would say "xxx traffic, experimental N416....etc..." In Canada you do not have the experimental category but "amateur built". So how do you anounce yourself in a...

My transponder installation instructions suggest to place the antenna over 6 feet away from human body to keep the radiation away. I have a composite fuselage and use an aluminum disc with the standard quarter wave antenna. If I place the antenna and disc below me so the antenna is on the side of...

Michelin recomends inflating tires with nitrogen. What about Argon? I got a bottle of argon I use in Mig welding aluminum. Isn't argon better than Nitrogen? What about the common 75% Argon and 25% CO2 welding mixture?
