High speed pass with Zombie. Sorry for the poor camera work, but you can still hear that wonderful sound. These passes are into a pretty stiff wind, and still she makes good speed.

The cowl is separate from the flaps and easily passes over the engine and bolted from behind, through the open flaps, in five places. Blind nuts were installed on the front side of these tabs after they were glassed in place.
Making the cowl removal easy is important when installing a Moki engine. They require a strict maintenance regiment.

Hi Gary,
I've been following your Meister p-47 thread for a while now picking up pointers along the way. The good news is the Moki 180 radial has the same diameter as the Moki 150 radial so fit shouldn't be a problem. Good info on the weight to power ratio. I was getting a little concerned because a buddy of mine is flying a 3W Bearcat with a Moki 215 and it weighs in at 50 lbs. Seems to have plenty of power but is by no means a rocket. I have the fiberglass fuselage and I'm guessing I will be in that 45 - 50lbs range when done. I'd rather have more power than not enough, I can always throttle back.
I like the idea of the bolt to hold the wing halves together. I built an Ohio Extra back in the day with a similar setup. Does the stock wing spare slide into both halves of the wing, not glued into either half? If you have any pictures of your wing setup, I'd love to seem them.

You should have plenty of reserve power Carl. Great that the 180 fits where the 150 does. Very cool. I have never had one to work with and didn't know that.
I am very happy with our 50lb P-47 and the 150. If you watch the "high speed pass" video, you get a feel for her performance. Got well over 100 mph today, I'm sure.
Yes, the spar is separate and slides in both halves. We like it that way as storage and transport is much easier. You may want to go back and take a look at our wing build. We use spray foam to fill the cells of the wings in critical areas after the top is sheeted. This is trimmed flush with the ribs. This gives a tremendous strength to the area around the gear and spar. At higher speeds, with a 50lb airplane, this is very beneficial. We also now fill the belly pan with this foam and this makes for a very strong pan for those belly landings that we are never going to have.
Zombie is hangered at my brothers house or I could get you some pictures tonight. I'll get some next time out.
We are starting another build for a customer, and the wing is being framed up now. I'll be posting new pictures of all this soon. This build also has the fiberglass fuselage. She will have a DA 85, but I'm still going to use the new cowl flap system and arrangement. Nice not having to unplug the cowl flap servos to remove the cowl. She will also have a two piece wing. Sierra Gear that I believe will be converted to electric, as we have in Zombie. The wing will have the landing light as well as nav and formation lights operational.

Here is my 8th landing with the new engine. Very different approach than with the big 2-stroke.

Thanks Tom. It was a pleasure to be there. I enjoy your club. Wish I lived closer. You have a wonderful facility and a great bunch of guys and gals.
I wanted to get more pictures of the kids that were there with our planes, and give the parents the opportunity to do the same. Lots of young ones there. Good to see. Next time maybe we can do a photo session or something.
Thanks again, and please keep it going.
Flew Zombie again last week end after a CG tweak (moved some batteries) and she was more stable in pitch. After mixing in a little down with the flaps as well, I think we have it dialed in now. We set up the trainer cord so I can get Brian on the sticks of her. As you know, I fly backwards on the elevator, so we can't hand the box back and forth. With a trainer cord, I can set the student box up with the correct movements, yet still fly reversed on my box. We will be building the Meister Zero, and plan to get both planes in the air at the same time, if not a Mustang or Corsair. I would like to have Brian soloed and all checked out on her before we put her away for the year. We'll see.

Some shots of the landing gear plate. The wedges are not shown on the plans, but are very necessary. They set the gear at the correct angle to the wing so they are 90 deg to the ground, and retract completely. The ones on the bottom but the blind nuts 90 deg to the gear so the bolts are straight.
