Beautiful job cde!

Suggestion: Use a Bisson Sport Style muffler instead of the stock OS muffler. It is better looking and much lighter.

Where can you get a set of plans for the 1000? I would love to build that one too. I have done the 40 and the 60 and they just get better! I can't find plans or any kits.

Thanks Mike and Jim. Im looking into the Bisson mufflers...heard good things about the Ultra Thrust mufflers too...any feedback? Here are some more shots with me holding it to give it some scale. I find just taking a pic of it on the garage floor doesn't do a lot in terms of size. The great thing is Im only 5'8 so I make it seem really big!! ha!!

I do not have personal experience with the Ultrathrust mufflers, but they are a tuned system and in theory at least, will increase performance at a specific rpm (full throttle) at the expense of all other rpms (mid-range).

I do have personal experience with the OS 160 and the US1000 and I can tell you for sure that you won't need more top end. The Bisson Sport Style muffler is lighter than the Ultrathrust, but not a lot.

Let us know how it flies!

cde:

I have it on a Twist 150 right now, running an APC 18x6W for accelleration and vertical. In the US1000 I would run a 17x8 for a bit more speed. I ran an ST 2500 in my US1000 and even though that engine had a lot less power than the 160, it was FAST and had excellent vertical. I plan to build another US1000 and put the 160 in it.

I have had the 160 on three planes so far, and none of them has required a pump. If you put the tank back over the CG, you may need a pump, otherwise, no.

OBTW: Yours looks like it has the long wing. The original short wing version has better aileron response, tracks better and is much easier to land. But it isn't technically IMAA legal. You can make yours a short wing by cutting the last bay off each wing.

Thanks Jim, you're right it's the long wing. The kit came with an addendum to cut down the last rib bay. I chose not to for your exact reasoning...I have no plane to fly during our clubs IMAA event so built it at 80". Down the road I guess I can hack off the last rib bay and narrow up the wing per the original RCM design. I'll keep you all posted on the maiden!!! (can't wait

Too bad you didn't add flaps - that is one sweet mod for this plane!

So, do you think you can put a small gasser like a CRRC 26 on the 1000?

The CRRC wouldn't fit inside the cowl. The only one I can think of that would fit without chopping the airplane off at the firewall would be the Evolution 26 GT. Of course that engine won't give anywhere near the performance of the 160, but hey, the gas is cheaper.

I maidened my US 1000 yesterday, and I was smiles from ear to ear. I let my buds fly it too and they were in awe with how well it tracked. The OS 160 worked well however I encountered that mid range knocking so I continued to richen up the low end. We put 3 flights on it and does that T-bird theme look good in the air!! Very easy to see. If anyone has any advice on tuning for that 160 I would sure appreciate it!!

If you are running the stock muffler, take the baffle out. I ran a gallon of 5% Omega through mine before switching to 15% and it has run very nicely right from the beginning.

Don't use flapperons. Look into my flap mod - it's easy to do and well-worth the effort

I love this plane. I feel sorry for the other planes I have because I just love flying this model. It is gentle on low rates and is responsive on highs. I have limited flying time on the weekends and this is my go to plane. The 60 size is great. The OS 75 pulls it around with authority, and it is a strong plane. It can take a good beating and some hard landings and come out with minimal damage. I have noticed some of the older models are showing up at the field like the Super Kaos and the Dirty Bird. They are good flyers and predictable. I wish glow fuel was as cheap as gas or there was a US big enough for a small gas engine.
