Thanks guys, its almost ready to come off the bench. Now that I know what I am in for,a just others should go a bit easier.
If anyone would ask me what I thought od this kit.. I would say this, the materials are very good and most all thw important parts are true, but as for size true ness.... Everything is slightly over sized, this is fine until you want to put a die cut part on it.,.. Every part needed to be tweeked to fit the spars. I kind of liked this because i was in full control of the fitment. Tight joints glue better with thin cynoacrylate glues(CA's).
I made up all the hardware mounting tabs yesterday so i can finally mount the last wing rib and get the servo linkage made up to run the aileron.
Now its time to decide how to do this??? Do I do it the standard way, pushrod to bellcrank, or pull-pull cables like the real plane had ??
Both methods are easy to do , but not easy to ajust. Cable system is a lot harder to ajust if you want it to look correct, traditional way just looks... Well, lazy...but it works good.
Access to ajustments are tough on this bird, because ,1) its ww1 plane, and 2), it has 4 fabric covered wings held on with cables or " flying wires"... So "hatches" are not very good looking on one of these.
We shall see... I like build the entire plane with radio installed before I cover it , just to be sure all is perfect... No need to rush, I dont like re- kitting them on the first few flights.

Well got the first wing off, and well underway on the second. At lunch time today I did a bit of reading on the trueness to scale this plane is, and.... Its not .... So with this in mind I am now under a new plan, not going to go all crazy scale , but just make it look decent as it is just a very large good flying rendition of a Pup. Boy I'm glad I found that link before I had invested more time and money, only to be disappointed when critics tore it apart at a competition.
I now feel a bit more at ease ;-) time to gett'r done.
Need to get some goodies tomorrow , like hinges and servos and ask about the new dsm stuff and its sucesability to radio interferance from an ignition engine. As i have a beautiful running Zenoha G38 i can use instead of shelling out $1300 on a fancy engine.

The G38 will swing an 18" loy loy ( propeller) at 7000 or so so a gear reduction drive ( need the extra weight in the nose) should let me drive a 22" or maybe even a 24" prop at 4500? I have a prop thrust program somewhere , I'll need to dig it up and see how much I need to reduce the speed for a decent pull with killing the little G38.
Turning the big lot lot should give some nice P factor like the real ones LOL.

Wing #2 done and PFF the board, it only took maybe 2.5 hours to get it done. Nothing better than good glues!!! Used up all the car I got from balsa USA ( only got 1 oz. Of thin) so went to a local hobby place(35 miles one way) and got a bunch of CA's all BSI industries too, and do they work good!!!! On the third wing now , boy its going pretty fast now....

Would have had the third wing done easily if we didn't get a pile of rain!! I was working away when I see water running across the floor... I run over to see where its coming from and see the bulkhead leaking wicked... Ran out side and had to chisel a trench through the ice and frozen ground so the water would drain, killed my evening... I' m beat to say the least but got it fixed and all cleaned up. I'll have pics for you guys tomorrow.

Well if water is going to come in you might want to make it a float plane.

Got delayed BIGTIME!! One piece of balsa missing!!! For lower wing spar, DOH!! So I had to find some balsa wood somewhere and lucky I found it at Michel's . a craft chain we have here, it was pricey, but well worth it considering the 70mile roundtrip for the other place.
So the last wing it on the board taking shape and I have beem working on a reduction drive for a Zenoah G 38 to hopefully drive a 26-10 prop at 4-5000 rpm? We shall see ? its almost done, just waiting for the timing belt pulleys and belt.

I really hope this works ,as it will save a pile of $$ and allow me to use this engine again.

Cowl is 13.5" . Got all the wings done, just need to do the top center section , but that will be after I get the fuse framed up. I have one side roughed right now, wife is not very cooperative.... Any rate its coming along. I want to order up some turnbuckles from Proctor , the ones that came with the kit are hoaky at best.
