I am presently constructing the ram air cooling shroud for my small continental in a 701 . Progressing nicely until one of those nagging back of the mind , is there problem here , issues took root . It's my current black cloud . Is there any nice weather out there ? Issue - SHOCK COOLING - cracking an aluminum cylinder head . Any info would add to my zero knowledge .

greetings...I'm new to the site so not sure if this is posted in the most appropriate spot....

i just installed a new Rotax 912 on my 1995 701. i had a Rotax mechanic do the install for me so it was done right. he commented on my throttle cable set up and thought it should be giving me some syncing problems. i was looking for other opinions on this and what others may have done.

the throttle cables are attached to the lever on the passenger side of the…

In October of 2012 my friend Bob and I flew our airplanes through 7 western states.  During our 12 day adventure we covered a total of 4,053 statute miles.  Along the way we flew through high mountains, valleys and canyons.  This was low-slow flying at its best. Often we were below 500 feet AGL.  The average AGL for the entire trip was only 1,003…

Instead of a photo journal for my build I decided to shoot some videos. I'm starting my project with the form blocks. I have never built with aluminum before so I figured this would be a great place to start. I can't figure out how to post the video instead of the link so here are the links.

I finally ran some fuel through my project.  I am building a ch 640 from scratch.  I am using a subaru engine with an RFI redrive that I built also from scratch.  I bought a set of redrive plans from Don Parnham, and also had him do my computer harness etc.  It finally purrs like a kitten.  I ran it today for about an hour checking cooling, oil temp, redrive belt tracking etc.  It really lights the old building fire again.  Since I am building from scratch it has been horfically slow due to…

As we work ever creatively towards using the Zenith STOL aircraft in practical applications, in the heat of the tropics, we are currently working towards a concept for improved cooling.  It has taken us a long time, but we are close to test flying the 'nose job' on the 701 with a Rotax 912iS up front.

The fun part is the new nose shape and the…

Hi all,

I am hoping to get some advice on changing the nose leg bungee on my CH601XL. I have no experience of building aircraft as I bought the XL when it was already flying.

I have bought the bungee (1080HD) but have been told that it can be a tricky job. Any advice would be greatly appreciated.

For those who have been wondering what is happening in Ghana - well, we have a few challenges!  You can read our latest newsletter in the PDF below... 

We are also working on a radiator gantry for the 701/750 for the Rotax 912iS (and the other Rotax installation, but we are working on improved cooling for the iS at the moment) and a really simple cowling modification that goes with it.  We expect to carry out flight tests next week, and, if all goes well, will share…

I learned almost the hard way of a problem with the VDO fuel sender used in my CH701. I purchased my wings and fuel system kit in 2010 and first flew…

We released our latest Aircraft Build Log app today!  At US$4.99 it is an absolute bargain.

This app allows you to use your iPhone to capture high quality photos and create your build log as you go.

The iPhone with it's flash, is small enough take photos of those dark and difficult to reach places in your airplane.

It generates a PDF build log and can export your log to a CSV file.

I have been out of commission for three months due to a motorcycle crash.  Finally was able to finish the work bench and start building again.

Here is a gently used Rotax 912 80 hp for sale.

I know the owner and aircraft history. Its good.

The Rotax 912 80 hp is great engine for the CH701 or CH601HD series aircraft. I have flown both models with the 80 hp Rotax and they fly great.

Wings, rudder and horizontal are done.  Screwed up the elevator (tip rib alignment) probably could have fixed it but would never be happy, scrapped it :>( , got some spare aluminum to use ;>)  Nothing another $400 can't fix.  We learn by doing, I hope.

Recently, We replaced the Bing Carby w/ a Rotec's 40 TBI to my Jabiru 3300.  Here the results: (After 25 hours running)  Still using same throttle system and air box system.   

1. Now can reach 2850 rpm in static run-up.

2. Shorter lift off distance.

3. Fuel burn @ cruise 5gph.

4. EGTs closer.  CHTs cooler.

5. Able to control mixture.

6. Very easy Starts.

7. Only use electric fuel pump for first start of day w/ primer once.

8. Climb…

First flight of Mac McCullock's CH750 registered AULA in Canada. Rotax 912S engine. Mac did a days CH750 type training with me prior to 1st flight.

Well, after my first 5 hours flying my XL I can report that this is a fantastic aircraft. It flys hands off with minimal trim, I must have been very lucky setting up the rudder alignment as it tracks straight and true with no rudder input. The Jabiru engine has plenty of power and am working out what to set the adjustable prop at. Currently getting 105kts at 2900 RPM. Am getting a lot of wind noise through the canopy frame so will look at sealing that better. With only 5 hrs so far am…
