We finally had the chance to document some basic performance numbers of our new CH 650 with the UL Power UL350iS engine. Yesterday was a beautiful autumn day so Zenith demo pilot Roger and I took the CH 650 up for a…Continue
Well summer and fall came and went and I didn't do a darn thing on the plane...debating on whether to get my materials ordered so I can work on stuff over this coming winter. But will I have time? Home repairs and other life setbacks have really gotten in the way!
Six years after ordering my kit from CZAW, ZK-ZMX finally took to the skies with test pilot Jerry Chisholm at the controls.
Omaka airfield owned by the Marlborough Aero Club is a little too big for this aircraft .I'll get closer for better shots as soon as I can
I have had another oil pressure sender failure. Thats 2 in 25 hours flying. Failure mode as follows;
works fine then you get the ocasional spiking high oil pressure indication of 70 - 100 PSI. This gradually becomes more regular until it stays on 100 PSI. For ground running tests I have connected a direct reading gauge to the oil galery to confirm a normal 40 PSI oil reessure.
Has anyone else experienced similar failures?
changed the prop today goes like a home sick angel after 5years 450 foot a min to 900 foot amin the engine o200 r r has not worked for all this time it goes like a rocket ray
Got the root doublers, strut attachment doublers and tip spars bent up the other day. Due to the happy combination of a Saturday morning to myself and the kids both sleeping for 3 hours in the afternoon, I pilot-drilled the doublers & L stiffeners to the spars and cut the extrusion to shape for the front strut attachments.
After some solid riveting practice, I'm now ready to attempt riveting the spars together... nervously... (jeez I'd hate to bugger it up on the last rivet!!)
I keep telling all the locals that it’s Bob Mac Donald who is sending all the geese to eastern Pennsylvania. Coming home from the last fly in the flock that flew past me where honking in French, I must be mistaken; they may be coming from Quebec.…Continue
I have a few questions.
I'm currently working on the 650B wings, and will likely go with a single dynon skyview display...i will be using the dynon AOA pitot which i will have to purchase now.
1. Are there any other sensors/components that have to be installed in the wing for skyview? (besides AOA Pitot)
2. Does the Dynon AOA pitot come with a cable assembly, and if not, from your experience, where can such a cable be acquired (or i can make) and…Continue
I am planning to replace the old style gauges in my CH601XL-B with a complete Dynon Skyview System including Autopilot and Dynon Angle of Attack probe.
I found a couple of examples of installing the autopilot servo's in a CH601XL, which is a big help.
But I do have a few other questions:
I am not sure where to put the ADAHRS unit in a CH601/CH650. I like to avoid re-inventing the wheel. Maybe there is someone out there who has…Continue
This VW ad from 1966 has become a classic and can still be seen in VW dealerships across the country. The above is prominently on display as a large framed poster in a shiny new VW dealer in St. Louis. While the cars have changed since 1966, the basic message remains the same.
Like the VW Beetle, the ad…Continue
Now have flown off the forty hour Phase One Testing. All in all a very benign experience. No real supprises except for the first couple of takeoffs being soooo quick.
Also have done first condition inspection and the Rotax 25 hour checks (100 hour check) with no problems.
Experienced no cooling problems with temps this summer in OATs as high as 98 F. Engine is Rotax 912ULS with Zenith FWF kit.
Have installed the Zenith VG's and have plenty of elevator authority. My…Continue
I have used up all of the .016 through .040 material I had on hand making miscellaneous parts, (270 parts so far). I laughingly call this method my plans built quick build kit figuring at the rate I am going in 3-5 years I'll would have enough parts to quick build an airframe.
I will be ordering the material for wing and center spars next week. Here are a couple
I have bought the plans to and still in the process of finding out all the relevant info on constructing the ch 750.
My question is in relation to specific Aluminium grades the plans call for the use of 6061 T6 or 2024 T3 etc. Does anyone know if they can be substituted for 5083
CH 701 are maybe not known for their x-country ability, but here is a Blog about crossing the the United States from Zephyrhills, Florida to our home in 100 Mile House, BC. The last…Continue
Anyone put thicker aluminum on wings of 750. whats the pros and cons?
I'm looking ahead to engine installation details - most likely for a Lyc O-235. (Yes, I know they are a bit heavier, etc., but I am familiar with Lyc engines and prefer to go this route.)
Seeking any advice on:
Engine mount - purchase or self built?
Cowling - will a CH601 fit ? (I have read that the 601/750 firewalls are the same size/shape.)
Cowling mounting arrangements - screws into the firewall flange?
Carb location - this varies with model # on other…Continue
I just bought a partly started 801 kit. I am interested to know if anyone has built an 801 with folding wings and if anyone has built an 801 as a taildragger?
