Hey there good people, I'm wrapping up my fuel system repairs an need the correct part number and size for the rivets so I can re install the top wing skins. 

I don't have any of the build plans or docs etc and I can find my way onto the online version. 

I have a ch801 

Thanks in advance.

I sleeved my plastic brake lines with thick clear vinyl tubing over their entire exposed length, then bonded the clear tubing to the edge of the landing gear with a silver adhesive silicone. Protects the tubing and the leading edge of the landing gear from rocks. There is no abrasion, nor any rub points. It hasn't come unstuck after 4 years in service.

Wondering if anyone has built straight skis for their 701 that used Bob McDonalds build plans? If so do you have any pictures you could share and how do you like them?

Has anyone heard about what happened to the guy or company that was making the small digital gages? He was on the Zenith site and they were in color and looked nice.

I used JB weld to mount mine, has held 4 years now

I ordered a set of brake line fairings from Zenith to take the place of the zip ties that are currently supporting my brake lines as they run down the rear of the landing gear leg.  I'm wondering what adhesive to use to attach them to my gear legs.  Has anyone had any success installing these?  If so, what adhesive did you use?  Thanks in advance for any help.

Information fo those considering using a lyc 0-320:

Installed a lyc 0-320 (150hp) in my Cruzer w/wood sensi prop.

I have all interior surfaces painted with 3 light coats of acid etch primer'

I have 750 stol wheels

Heavier cowl due to having to enlarge bottom of zenith cowl to fit standard air box and filter

Full exterior paint job

320 E2D with carb, slick mags, b&c alt mounted on vac pad, light vetterman exhaust w/2 mufflers/heat shrouds, and 2inch alum prop spacer for 13 inch vans spinner/ 2nd bulkhead.

w/ 3 gal unuseable fuel, oil, and interior.

Weight: 946 lbs.  CG very good with no weights needed.

1440 gross,    494 lbs usable.......180 lbs (me), 180 lbs full fuel, + 134 lbs of ? to gross weight.

As I will be flying alone most of the time, It fits my mission well with, hopefully, really good performance.

However, Considering increasing gross weight to 1500 lbs.  With 3.8 g load limits.

I need an older single axis trutrak autopilot. If you are upgrading I will buy your old one.

Price and availability. 

Comment by Ray Toews on December 26, 2020 at 6:06pm

Looking for info on a trailing link suspension for the nose wheel. I have a picture but no luck searching the web for info?

Comment by James W. Fisher on December 21, 2020 at 5:48pm

Interested in comments regarding the Franklin Sport 4 installation.  I have one with all firewall forward removed from a CH-200 project.  Thinking about a Cruzer install.

Comment by Robert M Bjorn on December 10, 2020 at 11:41am

   Mark Leppky,  I.m even newer.  I just purchased a bunch of parts and some assemblies for a CH-300 without any builders manual.  Was wondering if you could / would supply a copy of yours, with some financial consideration of course.

            Anticipating your reply ,  Bob

Comment by Mark Leppky on October 26, 2020 at 1:08pm

Hi, I’m new here. 
Have the CH300 torn apart for it’s first annual inspection. 

Nose gear frame is out for welding.
The tab that attaches to the firewall was broken off. 

Firewall stiffeners for the gear attach are cracked. 
Is this a common problem? 750hrs TT

Also the stabilator attach brackets have been significant changed compared to the plans. 
Is this a common problem? Was there a repair or upgrade available? The current fittings are made from a very soft aluminum alloy. Should I be concerned?


Comment by Terry Wood on July 28, 2020 at 8:14pm

Hi guy as you know I'm the proud owner of Tom Simards CH750. I'm having issues with the charging system on the Jabiru 3300 he installed. I'm getting a lot of interference on the com radio when I key up and talk in the pattern. The higher the rpm's the louder it gets. I tried putting isolating capacitors on the charging system to fix the issue and no help there. any suggestions?

FYI Just to let you all know Tom is not with us any more, He lost his battle to cancer and will be missed by many.


Comment by KenHarry on June 30, 2020 at 6:41pm

Hi All,

Well I'm jumping into it and have ordered the CH750 Cruzer rudder kit.  Looking forward to starting on it and getting my order in for the airframe kit. I think I'd like to go with the Viking engine, but am going to wait a while to finalize a decision once I get close to finishing the airframe.  I've owned and flown gliders for a long time, but figured it was time to add power to my license.

Comment by Stephen Wicklander on May 30, 2020 at 9:44am

Hey Steve,

I cut the angle and rounded the other 3 corners using a band saw and bench sander as per Drawing AA-01 and AA-02 on all the flaperon hinge bracket pieces (A2-1) and trial fit one piece to determine the location of the 3/16 inch hole exactly. Then I drilled them all and they fit perfectly. If you are less venturous you might want to trial fit and drill each piece separately. Just be careful because you have different left and right hinge brackets.

Comment by Steve Lemley on May 16, 2020 at 9:07pm


750SD Flaperon bracket. Is the 3/16 Bottom bolt hole drilled Now or just prior to attaching to wing?

Are you guys putting a radius on the bracket?
