Exclamation Geared Drives LS1 for RV-10

Last night we posted a new video (5 min.) on YouTube to show a new Chevy LS1 installation by Geared Drives on my RV-10. The video was taken recently during a test to set the prop governor. The engine runs beautifully and I'm looking forward to flying behind it in a few weeks time. We hope to be able to bring the 10 to Sun N Fun in April which means alot of flying once I get the FAA inspection done and completing the required 40 hrs for Phase 1 testing. I'm also looking forward to making Oshkosh and meeting other RV'ers from around the country.

Default Weight & Balance

Bill...I'll be following this with great interest. I'd love to know your overall weight so far if you have it...along with an idea of how the aircraft is equipped in order to get some sort of reasonable assessment of the Geared Drive package weight as compared with an IO-540 or Vesta. Thanks

Bill, can I recommend a mental re-set? Test flying a new conversion with a Big Show deadline isn't the best plan. Trust me please; been in your shoes and have the t-shirt. If it works great, fine. If it hiccups, take your time, there's always next year. In fact, the whole point is to make sure there is a next year.

You have a nice package. It's the little things that will get you.

I have the sincerest hope that this V-8 conversion is the one that succeeds. Its the cleanest, best laid out conversion I have seen. Bud is a nice guy and really knows his stuff.

Congratulations! It took us a year and a half from where you are now to flying! Shoot for Osh! Sun-n-Fun is way to close! It might even be to close for me to make it! You will enjoy flying it though!
What gear ratio are you running?
You are very lucky to have a very knowledgeable engine builder and flyer there. Remember it is a car engine in an airplane and throw out any airplane engine knowledge.
Is Bud going to do the test flight?

Default So much power!

I hangar right next to Bud's operation, so I get to see this on a daily basis. You just can't believe how smooth & powerful this operation is. At 3k rpm it just seems like more power than you would ever need. The PSRU speaks for itself, but what I really think is a huge part of the application, is the way the cooling system is done. It is absolutely a work of art, very effective, while keeping the weight towards the CG. I think weight is comparable to a 540.

Bud's new smaller drive for Sube's is test bedding right now, you can put your hand on the drive after running for an hour and its is barely warm. Hope this all works for Bud, he truly is one heck of nice guy.

Congrats Bill. Sounds great. I'll second Dan's thoughts here. It's all new and unproven however so finish Phase One and then some before making big plans.

Best of luck and we are all interested in your Weight and Balance!
