I am building the Thunder Tiger Lazy Cub. I am almost done but I am having trouble running the piano wire from the throttle to the servo. The instructions say that you should run the wire through the pre-drilled hole in the firewall. There is no pre-drilled hole. If I try to run it straight back from the throttle it would go through the fuel tank. Has anyone built this model that can help???

I saw that too. I just looked for where my throttle arm said the wire needed to go. Then I drilled it. Strangely enough, it had to go through part of the engine mount. I drilled right through the "flat against the firewall" part of the mount. It works fine. What motor are you using? I went with the O.S. 46LA. An 11x4 Master Airscrew tries to torque roll it! If you are using a 4 stroke, it may be harder to get a straight shot to the throttle arm. By the way, you're not expecting a slow put-put-putter are you? I set mine up with the CG at the front of the recommended range, and she is still the squirrliest plane I've ever flown. The tail is just too short. It will fly very slowly, but is still EXTREMELY RESPONSIVE. Larger wheels are good if you fly off of grass. I put some 3 inch Dave Brown wheels and it's much better. Also watch out for the exhaust spray. Mine soaked the right aileron servo every flight. After the first day of flying I added some makeshift servo covers to keep them clean. I like the Lazy Cub, but I bought it expecting more of a "trainer like" plane. This is no trainer I promise you.

Good Luck,

Thanks for the reply. I did the same thing you did. I drilled through the mount and fire wall, but the wire rubs on the fuel tank. I am using the engine that TT said the plane was built for the TT Pro 25.
No I am not expecting a trainer, this is my third plane. The first was a TT 40 trainer (crashed and burned), the second was the Aircore 40 trainer.

I'm in year number 5 flying 3D aerobats and fun flys for the last 3 years. I was caught off guard with this plane. I figured I'd be flying it from a lawn chair. It took a few seconds for me to catch up with it, then it was fine. I just am saying be ready for it. Depending on how much pressure there is between the wire and the tank, it may eventually cause trouble. Maybe slide a piece of 1/64 ply in between and silicon glue it to the tank or something. Then again it may not become an issue at all. Get ready for 10 foot diameter loops, it's a blast to loop this one. When you're used to it try it from about 4 feet high and listen to them gasp when the plane does it. Then do it again and idle the engine at the top and keep it idle. If yours turns out like mine, it will do it no problem. Then land in a head wind with no foreward movement. Then take off with no foreward movement. The plane does some pretty cool stuff. You will need good rudder skills to fly it slowly. The ailerons are nothing but trouble when you are flying at the slow end of the flight envelope. It's all rudder and elevator then. I like 1/4 throttle rudder eights mid field, at head high, right at dusk while the other guys are packing their trucks. But that's just me!

Sounds like it is going to be a blast to fly once I get the kinks worked out. Thanks again for the feedback.
