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.

SIG BACKORDER, WE'RE SOLD OUT

"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.

SORRY, SOLD OUT 

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.

SORRY, SOLD OUT, DISCONTINUED BY MANUFACTURER

Because the Kadet LT-40 is bigger than the average .40 size trainer, it has a much lighter wing loading, which lets it fly slower! Slower speed gives the student pilot more time to think and react to what the model is doing, thus making it easier to learn to fly R/C. Every major part of this kit has been pre-shaped, sawn, die-cut, laser-cut, routed, or whatever it takes to make it ready-to-install right out of the box.

Setups below would be my first picks depending on your purpose for the model. If your trying to learn or train a beginner, or just want a mild model with enough power to get out of trouble, pick setup around 1000 to 1400 foot per minute climb rate (fpm). An expert can do quite nice aerobatics on 1000 fpm, 1400 fpm and above is enough for first season pilots. Setups 2000 fpm and higher is agressive power.

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.

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!

This kit can literally be built as fast as the modeler can apply CA glue and accelerator. Fantastic flight performance using either 2-stroke or 4-stroke engines.

Special notes about electric from Dave: This model makes an excellent electric conversion. My first large electric was one of these on 20 1750FAUP Cells. Yikes, I'd love to do another one with modern packs! Here is how I'd do it. Yes, this is same chart as the 4 Star 40, similar weight and wing area. An under recognized yet excellent electric conversion model. Good weight to wing area. A little troublesome to get large NiMH packs into due to the wing tube. However, with Lipo's it's super easy to fit the pack. Below are my suggestions for a range of practical power systems.
