Notes from Dave: This is absolutely my favorite glow sport ship of all time. It's a classic kit. There was just nothing more exciting on trainer night than to have a graduated student come up with one of these for his 2nd or 3rd aircraft and ask me to test fly it. I dare say, I'd put a whole tank through the model and say, yes, it's still my all time favorite! The model is very pattern like for it's size, super smooth and yet retains all the personality of weekend sport ship. Friendly yet aerobatic and even aggressive if you set the throws for more spirited performance. They land like a dream, are utterly trustworth in any situation. You'll love it as I do.

Power Packages for setups in performance chart available. Includes Castle ESC, Himax motor and APC or Zoar Prop & Lipo Battery.

When equipped with a .19 engine, it makes a good first C/L trainer. Bolt on a Fox .35 Stunt engine, and the Skyray 35 will fly the complete AMA stunt pattern. Install a high-performance combat engine, and you'll have a real "Hot Rod" on your hands.

Died-in-the-wool C/L fliers will appreciate the Skyray 35's speedy assembly and super tough wing design - which features spruce spars and die-cut Lite-Ply wing ribs. This is one C/L profile stunter with a real difference!

Notes from Dave: I've flown electric control line a number of times and it's a real blast! Any kit can be converted with a little effort.

Suggested Fox 35 Emulator E-Motor Setup: Himax 3516-1130, Thunderbird 36 ESC, E-Flite Control Line Motor Timer, 3S 1500 Kypom Pack and 2 each 10-6 APC-E Props. Setup delivers 10,180 RPM (Fox 35 Stunt 10,200rpm), 58 mph pitch speed, 47 ounces thrust, 374 watts power @ 33.2 amps.

Suggested .19 Glow Emulator E-Motor Setup: Same as above except with 9-5 prop, 11,040 RPM, 52mph pitch speed, 34 ounces statics thrust, 246 watts power @ 21.9 amps.

Both the KADET SENIOR and KADET SENIORITA are also popular with experienced fliers who are tired of the nerve racking panic that can accompany a faster model. The KADET SENIORITA flies so slowly and gently that just about anyone can handle it on their very first try! If the student pilot gets confused, merely let go of the control sticks and the KADET SENIORITA will recover itself and return back to level flight.

"The R/C Trainer That's All Laser Cut", As you would expect, the new LT-25 inherits all the same gentle flying characteristics of the other legendary Sig Kadets. It has the same light wing loading, which allows it to fly slow enough to give the student pilot time to think and react. It has the same "hands off" stability on all axis. If the student pilot gets disorientated, simply let go of the sticks and the LT-25 will recover and return to level flight within seconds.

Special notes about electric from Dave: This model makes an excellent electric conversion and is perhaps the most popular one of all time. Super light weight, large as or even larger than most 40 size trainers. The only lighter weight 40 size trainer on the market is the Radical RC Intern 66.

Like it's older siblings it retains the easy and relaxed flying characteristics of the Four-Stars. Open the throttle and increase the control throws and it will do about any wild maneuver your thumbs can dream up. Add to this the portability of a smaller size and the quietness and convenience of electric power and you have another winner for sport flying. While designed for electric power it is configured to easily convert to glow engine power in the .15 to .25-engine range so you have the best of both worlds.
