Tim,

Don’t let the jer.. er, gentleman, on the other list know you questioned the safety of that single support at the rear of the engine. I did and he summarily dismissed me from his list. Your plane is really looking good!

You have a very interesting day job! Lots of action! Guess we could say the same for your night job what with 4 pregnancies in 3 years! :>)

Kelly,
I am unable to post, please post it for me.

All Rotary Flyers,

I have had several inquiries about my plane/hobby. I am currently constructing a Vans RV-10 utilizing a Mazda 20B. I have not posted much since I have spent the majority of my time working on the plane and deploying. I have been working on it for approximately 3.5 yrs, during this time I have had three kids expecting my fourth and been deployed for half of the time. I am currently a Coast Guard Helo pilot specialized in Counter Drug operations. If anyone wants more information about this issue just let me know. To date I have stopped several go fast vessels seizing over $70 Million worth of drugs, needless to say I am very busy with my day job.

Now to my night job. I have been constructing my RV-10 in my garage. I have the wings, tail, fuselage complete. The wings are currently located in a 14’ utility trailer next to my house. I have the Engine mounted and working on placing all the amenities on it. Attached is a picture of my engine mount. Many have seen it posted, it is the S-Beam, MODIFIED. I did not feel comfortable with just having just a small tab on the oil pan supporting all the twisting moments of the engine, so I had Ed Klepeis modify it for me. Also, the 1/8” aluminum oil pan in my opinion was not beefy enough to make me feel safe, so I had a 3/8” Aluminum plate mount over the top of it to provide more support. 2 years ago there was no one manufacturing the engine mounts for a 20B on a RV-10. Now Ed has all the dimension making it easier for others to find a mount. The original engine mount would have probably worked fine, but as the operator and owner I did not get that warm and fuzzy so I decided to beef it up. Now I feel more comfortable. I currently have an overall length of 53” from the firewall to the prop hub vise 39” of the typical Lycoming. This should help on the CG. I have been very cognizant of the weight of all the components that I have been placing in the engine compartment and panel. I have a Sam James Holy Cowl and he was able to lengthen it for me.

While I wait for the products to arrive, I have been working on the wiring. I plan to run a dual rear mounted battery electrical system. I am trying to make the system as simple and easy as possible. I plan to run one battery directly to the essential bus which will have the EM3, EC3 and all essential items for flight and it will be connected to the main bus via a crossfeed contactor. Wiring is still in progress.

My plan is to have it running the first of the year, but I am getting ready to head out again, so we will see. The wife also told me that I would have to have it completed by March since the new unplanned addition is due in April. We will see how things go.

If there are any questions or suggestions please let me know.

Tim Holt
