Speed Stick.
A little project I'm working on. It was a GP Big Stick 40. I got it off Craigs list for $49 with a TT .61 Pro and the Mac's tuned pipe. He also threw in an OS .40la and an old K&B 61. Anyway the plane was pretty oil soaked especially the tail section. So I stripped it and cut off the tail and scratch built a new one. He also had 6 oz of lead in the fuse to ballance the TT .61 so I took that out and relocated the ele/rud servos to the tail. I decided to clip the wings 1 bay + the WW I style tips. I glassed the wing center section and have reduced the size of the controle surfaces to minimize flutter issues. I bought a 10x8 APC prop for it thinking this will be the best speed prop for it but I am open to other sudjestions. I went through my partial roles of covering and came up with this Tower Hobbies Yellow, Hanger 9 Orange and Top Flight Red. The way it turned out I am concidering calling it "The Skittle Stick" because it looks like Skittles candy to me. I am hoping for 100+ mph straight and level.

RE: Speed Stick.
That's a sharp looking plane!
I'm always amazed to see models made out of the lightest materials, but with big globs of lead glued to them. I've even seen lead stick on weights at both ends of the same model!
Regardless of the speed, those planes are great daily flyers. I flew my .20 sized Stick with lots of different engines and props for many years. It was fun to coax speed out of, or to go low pitch and fly like that.

RE: Speed Stick.
Thanks CP. I never really liked the looks of the Big Sticks but for $49 I figured I could change the look enough for me
It may just turn out to be my windy day flyer.

RE: Speed Stick.
I did something similar to what you're doing.
I learned that it's a waist of a good engine to try and make a "draggy" airframe go fast.
It was fun but the model sucked fuel like it was going out of style so I put a AX .75 back on it and I'm saving the Jett for something else.
I love sticks...
There's another guy at the field with one and we had a blast drag racing on the ground. It was a Hoot! Down elevator at wide open throttle ALL the way down the runway. Ten feet from the pond and pull back on the stick.....
Land and do it all over again... Sometimes a nose gear CAN be fun.

RE: Speed Stick.
The wing is a bit thick to get any real speed out of it. But clipping the wings should make it move a bit faster. I wish I could justify buying a Jett engine but I am just dabling with speed right now. I recently planted a CG 60.5 in Ultimate and may do something with those wings since they have a much thinner airfoil. I will likely scratch build a fuse for them as oposed to just grafting them to the stick.

RE: Speed Stick.
Thats where you guys in the USA are so much luckier than the rest of the world, The markets cater for you. In Australia, we get dribs and drabs as the importers decide and it takes a while for the good stuff to filter through.

RE: Speed Stick.
I finally finished putting the stick back together. I got 14,300 RPM with the 10x8 APC so I will just have to take it to the feild now and see what it actually does

RE: Speed Stick.
I did not have a whole lot of fuel so it was a pretty quick trip to the feild. A little breezy but not to bad at all. The first flight was a bit scarey as the plane was all out of trim and pushing hard through the turns. After I got reletively level flight I did a loop and it corkscrewed out so I made some rudder adjustments untill I gould get a good loop. Then of course I had to readjust the ailerons. All said and done I open it up for a few fly by's and I feel I reached my goal of 100 +/- 10mph on the straight and level. easilly breaking 100 after a dive. I got absolutely zero flutter (that I could hear over the pipe Oh, and I found another 700 rpm tweaking the needle some more bringing me up to 15,000 RPM on the 10x8 APC. Little TT .61 Pro can spin. Downside to the plane is it is a bit heavy with this set up and likes to come in hot.
