Hey all,If you're in the market for a leather flying helmet, you might want to ckout sportsmans guide. They have what APPEARS to be a nice WWII replica of agerman flying helmet in brown and black and the price is good. I bought one(can never have enough!) but haven't seen it yet so can't vouch for quality.Based on the comments, sizing is small so read the comments carefully if youget one. http://www.sportsmansguide.com/net/cb/g ... __________

Thanks for the responses guys. I am the third person involved with this aircraft.The original owner knew the CG would be aft but the second owners who didthe firewall forward didn't think it looked right and so they cut out the aluminumand did the cabanes vertical. She balances near the rear limit and hassome generous aluminum fixed tabs on the elevator and flies nicely trimmed at60mph but when I look back there is significant down elevator deflection. Since I switched from the metal prop to a nice cloudcars wooden prop it won't helpthe weight and balance any. So it sounds like all I might need to do is makesome new angled struts. For the big holes in the aluminum I was thinkingof sewing on some leather to fair in the struts and cover the ugly holes.JoeRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

FYI, I just received the flying helmet from Sportsman's Guide and it looksvery nice. The leather is very soft and the quality seems good. I wearonly a 7" hatsize and they accidently shipped me an XL and it fitsperfectly.Douwe________________________________________________________________________________

Dan, I think we are all contemplating this. Did you scallop the aft edge of this plywood or do you have a spanwise ridge on the upper suface of your wing where the fabric transitions from being supported by the plywood to being unsupported?Does your airplane stall gently or sharply?I have always been under the impression that the aft edge of LE plywood should be unsupported between the ribs to allow for a smooth airflow transition.Greg ----- Original Message -----

Greg,No scallops. Just a straight cut (spanwise ridge). The plywood goes back to the aft edge of the spar. I would describe the stalls as gentle. I have no idea why my ship would be any faster than others. It has all the draggy stuff the others do. The only other thing I can point to might be my aileron piano hinges. These are somewhat unique, in that they are mounted flat on top of the wing (and aileron), upside down, and I actually recessed the wood where they are screwed in, so that the top plane of the wing is not upset by the thickness of the hinge or the bump where the wire goes. I can't imagine it can make that much difference.I had this wing all complete like that before I heard others say to do it the other way. I was kicking myself because it looks better the way most have done it, and I was admittedly worried about that ridge acting like a spoiler. Its not much but it is there.Maybe its the 1/16" wire I used to brace the tail (like the Last Original). :O)Dan HelsperPuryear, TN-----Original Message-----

My understanding is same as Greg's. Dan, I think your obvious speedadvantage is coming from those Fancy Dan wheel covers!!Seriously, though, you may have hit upon the best prop pitch/dia/profile.ifyou are happy with its climb. Prop #2 for me was definitely a cruise prop,causing me to throttle way back to keep it under 90! At that speed, "Ididn't like it much!" But it had a very poor climb rate.Gary BootheNX308MB

When Larry and I flew over to Brodhead together a couple of years ago I had to do S-turns for him to catch up. As I say, I don't know why. He says his is the world's slowest Pietenpol, and has tried other cylinder heads and props trying to get it to go faster, to no avail. Tools, you may be correct that my rigging just happens to be as good as it can be.Dan HelsperPuryear, TN-----Original Message-----

Here is another way to build your own static balance tool. I have not built onemyself but had seen it printed somewhere and drew this up quickly from memory.I don't see any reason it wouldn't work. Please don't take me wrong on my last post. dynamic balancing is good and I thinkit has its place with metal and constant speed props but I really don't thinkwe need it on our Piets. They are simple machines. Attached is the rough drawing I made.
