Status: online 		Has anyone built the Ziroli P-40 with the fiberglass fuelage? I was thinking of going that route but wanted to hear any comments good or bad. What engine fits the best both in power and cowl concealment? I have heard some favorable reports but wanted to get specifics. Thanks.

Is the wing a bear to build with all those different tapers?
Is the G-62 the weapon of choice for this bird? Does it completely cowl? Is there a better choice as far as carb location, exhaust etc..?? I really appreciate the help from you warbird guys.

Horizon has an adapter that'll reduce the distance between engine and carb so it may fit without cutting a hole.

Status: offline 		Now youre talking.....
Here is my die hard Warhawk, which I let go to aquire my P-38.

This plane is a total blast to fly, hands off is absolutely straight and true once you get it airborne. Take offs are as tough as your powerplant. G-62s are not so hard to get aloft, with minor right rudder inputs plenty of rudder authority.....of course yours truly had to go whole hog and drop in a Brisson 5.8, because the 4.2 that was initially installed just wasnt giving me the wow factor that I like in my warbirds. This now requires that I STAND on the rudder. If I so much as let light on the rudder, p-factor is gonna send it into a military efficient LEFT-FACE-MARCH. But once the speed gets up (I literally gun it and go) then you can start to relax a bit. Do not gradually bring up the power with an engine this size, with each new power point, p-factor changes, as does your rudder input requirement, and you chase the bad boy all the down the ramp, looking like a rookie the whole way. Granted, it aint flying no where near scale at full throttle, but I dont compete on fun flying days. When I do I change props to something bigger and with alot less pitch.

You can get most of either the exhaust or the carb concealed, both is a challenge, and with the 5.8 it aint gonna happen. If you look closely at the picture, Brison used to make a really cool blank, that I had a pipe welded to the end of, ran some copper tubes and elbows, then exited the hot stuff through the cowl flap openings.

A very easy plane to land as well, with acres of wing area. I ran a single glass rod to the elevator, also keeping it all inside, and a Hightec 700 series on the first, the a 705 metal gear on my current one.

Harold, the carb does not have to stick out of the cowl. My carb did not on the 4.2, the 5.8 of the old one, nor the 5.8 of my current one either.

Transport the wing, get a surf board rack for your car. Or let hang out the back of your 8 foot bed truck, like me.

Engines are a matter of tastes, you can do some really "scale" flights with an engine as small as a g62. I wouldnt personally go any smaller than a 4.2 electronic ignition. I used be bummed as how long it took to get off the ground, (ok so the original weighed close to 51lbs, thats beside the point) but once the 5.8 went in, it was hang on mommma. I now dont buy warbirds unless I can cram one of these beauties in it.

Talk Brisson into making that Blank exhaust again, its a gem. Very low profile and undrilled so that you can do whatever you want to with it, clean and rugged.... hello Brison, you listening...I will take two.

Status: offline 		Hey Injun, before I actually took ownership of the plane, it was owned by Vic, Mr Fw190, way back when. An intermittant elevator had it pancaked on its maiden flight. I bought it, got a new fuse, and began to build it as if it were one of my slope gliders, with no regard for weight what so ever. I sanded the wings, but instead of going all the way to the wood, I went to the glass cloth, and then glassed again with 4oz weight. Yeah yeah I know. Then I went and added a tail wheel retract, and paint it so thick, that you could have troweled the stuff on. That brought the plane to 43lbs. Then one day out at mail square park (RIP) I got a radio hit while flying over some rc cars, and put the thing into a tree at at golf course. Thank god for the tree. Another major repair of the wing, and yet another fuse later, and now I am up to 50 plus pounds. The cool thing is that the plane was balanced right on the cg, and even at that weight, once you got up, and on step, it was easy to handle. Never mushed in the corners, slowed down well for approaches, and with about 20 degrees of flaps, it still was able to slow down enough to handle a short field landing. Yeup, its a winner, I will always have one in my stable, heck I would even buy back the original, if I knew where it was, just for sentimental reasons, and I dont get sentimental. Unles you are talking Bearcats and Lightenings.

don't forget about the wing walk - 4/26/2002 10:24:15 AM

Status: offline 		I mean the car tire wing walk.... eeeeeek! that really added more weight, about 2,000 lbs devide by 4 ( could only get one wheel on the wing)

The spec when I original built it was at 33lbs with a Sachs 4.2. Learned a lesson from a single elevator servo. I cut the foam wing. Foam wings build a little heavier than built up, but it is a lot stronger. When the elevator failed, the fuse was totalled but the wing was in perfect condition. If you want cores, balsa dynamics now cary a set.

Glass fuse and foam cores is a good combo, and seeing Ray burn up the sky with his on a Brisson 5.8 takes the cake.

Status: offline 		I know about the foam wing cores, I'm using a set on my "NEW" P40 which is to replace my "OLD" P40 that had a wing failure in flight!
Only the stab and rudder survived the crash....... Mine had a G62 in it and seemed to have more than enough power but I was wondering if maybe a Sachs 4.2 would fit without having to mangle the cowl up???? Anyone know?
