Came into possession of a ground looped T18 last summer, bought it with a partner from the original builder. Bert is getting to his mid eighty's and decided it was too much for him to fix up.

The plane was completed in 1983 and has about 1500 hrs on it so there is a fare bit of freshening up and up dates to be done. The ground loop damage was easy to fix, new gear and a few other parts from Cubes set that right. New wheels and brakes got rid of the original oversized ones and will allow for wheel pants to be added. The O290 has been rebuilt with O320 heads and we have been promised an extra 10 HP on the O290 Deluxe!

Some decisions on what to replace in the panel but the vacuum instruments and venture tube will be gone for sure.

Hope to see some T18s at Airventure this year and talk to you about your planes, ours won't be in the air by then so will be driving down.

Nice work. I'm excited to hear about it flying.

Are you based in Canada or the US? If the US, have you already handled the import paperwork? I was considering buying an Alberta plane, but thanks to Lee, ended up getting one from Las Vegas.

If the airplane isn't flyble, I wonder if you can trailer it across the border, get it ready, then do all the airworthiness and registration work.

Regardless, glad to hear you are bringing this T-18 back. When was the groundloop and how long has it been sitting?

There's a group of Thorp pilots meeting in the SE US this weekend. I was hoping to make it there for a day, but will try to be at Oshkosh instead.

Will you keep a running thread of your work and progress?

Me too. N8786 is a flying project. Removed the vac system and got a 12.5# weight loss. Tweaked a few things up front, mostly aerodynamic and now get a solid 145+ kts from my over pitch prop. That will be fixed at the winter re-hab with new pistons, repitched prop, moving the rudder pedals, elect trim, and some cosmetics and glass.

The aircraft had been ground looped in Feb 2018, nasty crosswind and commercial traffic behind resulted in exiting the runway a little too fast and losing it. Purchased it in August and trailer-ed it out from CYQR to our little air strip CDS2, it's staying in Canada close to where it was built. Nice to have the builder around for advice.

Will post updates as we progress the project.

Fixing up the baffles and installing new seals now.
When test fitting the cowling found the engine is slightly further right at the front now with the new landing gear installed. Checked the engine is square to the engine mount ring and can see no mounting errors so must be a small difference in the new Gear from the original. Added a few washers on the right side engine mounts to bring it back to original position and alignment with the cowling.

That’s interesting. It’s hard to measure, but it should be mounted 3 degrees right. I put a piece of tape on the boot cowl on the centerline and an angle finder on the engine.
