OK !!! Ordered 2 long shaft engine conversion kits from Jag engines along with the "Fancy Prop Nuts". Will need the prop nuts for my starter to work. Getting stoked up on this next build. Here's what I have in mind.........

Been flying the USS with my present Ryobi 31. What it consists of is a 45" long 3 1/2" square PVC fuselage (Fence Post Cover from Lowes) , swiss cheesed to save weight, has a 72" wing with 15" chord (ailerons included). Weight is around 13.5 lb. Flys very respectable.

What I'm wanting to build on the next project is similar Using a 38" long 4" PVC fuse (swiss cheesed) , 60" wing and 15" chord. Trying to make one more agile, 3-D. With the smaller fuse and wing, hoping to save some weight. Do you think this plane is flyable ? or do you think it will be a waste of my time and money ???

I like the Fence Post Cover PVC fuse as it is; 1. Straight 2. can take a beating if needed 3. No construction time. I have made coroplast fuses, but I've found with the bigger-heavier planes, they can bend-warp a lot easier. A lot of my smaller planes are coroplast construction.

One further question before I close. What props are you using with your Ryobi's ? I've been using Dynathrust 18 X 6, 8, 10 with good results. Can't find Dynathrust new in that size anymore--though I did find and buy 3 off ebay yesterday. See that Master Airscrew has size in their "Classic" series. Is this a good alternative ?

Thanks
