Back home

I'm back in the US. I'm moving in a few weeks, so won't get much done before the Christmas break. My form and cutting blocks shipped home ok- I was worried about getting them through customs. I made a trip to Harbor Freight and got some tools yesterday.

Cutting Metal for Wings

After spending most of the summer on other projects and airplane work relegated to making form molds, I resumed work with a vengeance this weekend! Having received the first delivery of sheet aluminum, I cut out one of the wing spars along with root ribs, rear ribs and nose ribs. My forearms are as big as Popeye's! Wasn't able to finish trimming the rear rib forms as I wore out my router bit. Will be spending a lunch break at Lowes one day this week!

BMW 1200GS in CH701

I am looking for either the drawings or complete engine mount (proven) for BMW 1200 GS installation into CH701. I have Engine complete with reduction drive and Kiev prop (very nice combination) which I am thinking of fitting to my 701. Can anyone help?

Hi all...anybody have an easy solution to the flapper on hinge bushings, kind of a oddball size. Thanks

Streamlined Struts

I've spent a considerable amount of time researching streamlined strut covers to reduce drag, better performance.  I've found that uflyit.com sells two sizes.  The smaller size fits our (701) struts, but are very difficult to slide on unless you use some form of lube.  I used silicone, and they went on very nicely as opposed to doing one with no lube (very hard), and baby powder on one (no difference).  They look good and are secure.  you can change the angle of attack fairly easily.  The…

The Adventure Begins

After watching and admiring Chris Heintz and his practical designs for many years, I finally decided I could either keep waiting for the rest of my life or actually get off my fanny and make a decision.  After a few sleepless nights, I finally ordered my CH 750 quick-build kit on September 30, 2013.  Needless to say, my nights have been filled with flying dreams ever since.  As they say, "The adventure begins".

Weekly Chat

A few years ago we had an active weekly chat that at somepoint went silent.  I'd like to see it revived, this time using this sites built in chat room.  We use to do it on Monday evenings.  I'd love to see this get going again. Any opinions?

A Funny Thing Happened on the Way to the FSDO!

We were discussing the pros and cons of using a FSDO inspector vs a DAR. This reminded me of when I got my Repairman's Certificate. Every word is absolutely true!

At the conclusion of my successful AW inspection, the DAR said "Unfortunately, I can't issue the Repairman's Certificate. You'll have to go to the Nashville FSDO (90 miles away) for that. Be sure and call them and make an appointment - they have a lot of security now and won't accept a drop-in visit!"  Sooo, I dutifully…

Cowl Thermal Blanket, DIY

Update October 20, 2013. We've seen temps into the high 20's. The thermal blanket is working well. A 60 watt light bulb works well, along with the 25 watt heat pad in the oil cooler plenum. At 25F OAT temps are, oil 59F, engine EGT/CHT 45F, airbox/cowl temp is 51F. My experience has been that engine/oil temps over 45F, the engine will start quickly.

I'm going to order a 50 watt heat pad, that is a better size for this climate. More data later.


Another flying season…

Back into it!

I was ashamed to see I hadn't done a build update since February 2012 - 18 months!!

Had actually done some building work in that time (not much, admittedly) - but have done the rear spars, clecoed the top skin on the right wing and flipped the wing over.

Today I got back into it after a few months of no activity, drilled the bottom skin and positioned it, and got a few clecoes in.  Glad to break the seal again and hopefully will be doing more building in the…
