GP Big Stick 60, Jett 90L with Long Torque muffler, 18oz tank and a Vess 14/6
Looks like fun huh.....he he heh heh
I'm building a big stik 60 as we speak. Can you tell me about the installation of the servos for rudder and elevator? I'm considering doing this as I'm putting a 90 size engine on it. What modifications did you have to do and was it difficult cutting into the fuse? Also, what length servo extention wires are required?
Also, I've heard that the horizontal stab is suspect. I mounted with 2hour epoxy instead of the 6minute stuff that the instructions recommend. Did you consider tailwires?
I used a wood Master Airscrew 14x6. (I'll get some APC's this week) The plane jumps off the ground. It was a little fat in the mid range and I tweeked it about 1/8 turn. Transition is perfect, Idle to full throttle....ZoomZoom. Vertical performance is to say the least FANTASTIC. It's like a rocket ship.
No dead sticks, No blown plugs, No Problems.
I'm still running fat but the engine is new so... I wanted to make sure that it wasn't getting hot. When I landed I could put my hand on the head breifly. Still getting to know the engine, we made three flights but it looks like we'll have a long lasting relationship.
I would love to fly the same model with a YS 110 and compair the two. I think the Jett may be a better set-up. It's got the guts and still has long legs for the low high speed pass. All on 15% fuel with the weight of a .60
The sound on the down leg reminds me of an old Husqvarna I used to own
It's a GREAT SET-UP!!!!!!!!
To install the sevos in the rear, I made some 1/8 ply "servo frames" and covered them with monokote. There is a blukhead/former that is one servo length forward of the leading edge of the vertical stabilizer. When you make the servo frame use it as a guide to eyeball where the servo should go and start to "Dig" in the middle. Once you get a hole started you can feel inside and find the former/bulkhead.
I also make a ply rear support and use Bamboo Skewers (2) to give the vert stab some extra support. After I measure and glue the horz/stab in place I use a drill and drill a couple holes through the bottom up into the vert stab. I epoxy a couple skewers and stick them through the bottom into the vert stab.
The ply bottom support sandwiches the horz stab and covers the two holes I just drilled into the vert stab.
I think I used 12" servo ext.
I like the Fults Tooling nose gear and my model will turn on a dime. It's fun because we have runway races before takeoff. Because the rudder servo is in the rear I added an additional servo to steer the nose gear and used a "Y" harness to tie the two together.
