Folks
I have ordered a wing kit from Javron and I will post a "Builders Manual" on here as I go. This will also be made into a hard copy "Builders Manual" that will be given out with Javron Wing Kits in the future.
I have ordered a round tip, very stock wing kit. My plan is to build a set of round tip wings and compare them to my current "Square Tip" wings to determine the performance differences, if any. Over the years we have all heard about the square tip wings and the performance difference but every time I have read or heard of this, and the "performance gains" the wing change out has been accompanied by a myriad of other changes done to the airframe at the same time thereby masking the true affect of the wing. My intent is to change only one variable, the wing itself, and try to document the performance changes as accurately as I can. I received the following information from Jay DeRosier at Javron regarding his wings........

Just thought you may be interested in these numbers. We have all four different wing configurations in the shop at the same time so it was a perfect time to compare weights between them.
All weights include fully assembled wing with flap, aileron, gas tank, tank lid, all internal pulleys and hardware. These figures do not include any covering, fuel tank plumbing, pitot or static plumbing, or lights and hardware. All of these wings were weighed exactly the same with the same parts installed.
Round Tip Wing with 18 gal tanks 91 Lbs.
Round Tip Wing with 24 gal tanks 96 Lbs.
Square Tip Wing with 18 gal tanks 99 Lbs.
Square Tip Wing with 24 gal tanks 104 Lbs.

Javron provides these wings in Kit form with everything predrilled and all parts included to include the flaps, ailerons, fuel tanks, tank covers and all pulleys internal to the wings. He does not include lights, pitot static parts, wires, cables, or fabric and paint. The kits run about 13.5K. A complete set of wings all built up runs about 18.5K
I currently have square tip wings with 18 gallon tanks on my Javron Cub. That build thread is here......

As before, I will try to weigh everything and post the results here so you may build comparative data if you choose to build up a set of wings using a different kit or materials. I stopped in to his shop and had an opportunity to see his new shop addition.
This is the welding part of Javron. Currently about 8 fuselages under construction. The shop expansion will give room for more organization and also (hopefully) speed up construction, thus reducing the time delay between your order and actual delivery.

The outside of the new building/addition. This will not quite double the size of the shop but it is a significant expansion. The building is 60 x 100.
Inside of the addition. This will eventually have a dedicated area for parts and shipping. Again, Jay is trying to get better delivery times. This will also allow more room for "Builder Assist" which Jay says he is doing a lot of. You can come spend a week (or more depending on your pocket book) working on your kit in the shop. This is a HUGE jumpstart on building your kit and I can see it saving months and months of work.
So........I hope to get my wing kit before the end of the year and I will document the build here as best I can.
Hope this helps
