Yeah, many factors can impact a glider’s flight time… for example, how high was it launched? Did it transition quickly into a glide? Did the glider get help from a thermal? Was the glider heavy or light? Did it have a large or small wing area? The last two questions might be the most important. But, how do you say the glider was “too heavy” or had “too little of wing area?” These are relative terms. So, therefore, we can calculate the potential lifting performance of the glider (called wing loading) by taking the overall Weight of the glider divided by the Area of the wing. e.g. L = W/A. The smaller this number, the better. Let’s do some math: Our 12” Tornado has a weight of around 8 grams and a wing area of 23.6 in^2. Its wing loading = 8g/23.6 in^2 (0.34 g/in^2) Our 36” Tornado has a weight around 50 grams and a wing area of 127.25 in^2. Its wing loading = 50g/127.25 in^2 (0.39 g/in^2) So, even thought our 36” glider has a wingspan 3x longer than the 12” glider, the ratio of weight to wing area is almost the same as the 12” glider- and slightly worse. Theoretically, in perfect conditions, if these two gliders were flying side by side, the smaller glider would have a slower sink rate and better flight time. In conclusion, an increase in wingspan does not guarantee an increase in flight time. Instead, calculate its wing loading for a better indicator of potential lifting performance of the glider. I appreciate your comment! 😊

@@NighthawkGliders Oh boy man, what a generous answer! Thank you so much! I will copy-paste this. I'm planing on making my own rc rubber sail plane! Be safe. o7

@@NighthawkGliders Also, I subscribed! <3

Yeah! Get some balsa and build some gliders! But I caution you on being selective with your balsa selection. A hobby store might be better (and lighter) than Hobby Lobby. Good luck on your builds and have fun! 😊

@@NighthawkGliders ok thanks for this appreciated advice!

Gorilla brand super glue is my favorite. You can easily find that in most hardware and grocery stores. You’ll want a super glue that has a medium viscosity. “Regular” super glue is typically way too thin. You can find other brands of medium viscosity CA glue and balsa at hobby stores. Thanks for buying the plans! 😊

Many thanks appreciate you taking the time to reply.

Cut 2 strips of balsa 1/8x1/32x1/32 and glue one on each underside trailing edge of left and right stabilizer next to the fuselage. This will help reduce the loopiness of the launch. I call these “trim tabs.” If still too loopy, add more until you get desired result.

Thanks for the compliment. But we cannot help you regarding CO2 cartridges. Sorry.

Thanks! Glad you like the glider! 😊 I find the best CG is at 50-55% back from leading edge! If you glide looks good, and you’re only getting just 12s flight, I suspect glider weight might be a factor. Balsa selection is key. Try to build a 6-8g glider and fly on calm days. Wind and launching technique can also play role in flight time. Good luck!

@@NighthawkGliders ok thanks l will give that a try! I will also probably build a second one to compare the difference. Im going to a model shop soon so I will make sure to pick up a selection of different balsa sizes and see what works best, and anyway experimenting is all part of the fun! Thanks for the feedback. 😊

Yeah, sorry. A failure on my part. You’ll want the tail to lean about 1/4 inch lower on one side than the other. If you are right-handed, lean tail to the right as viewed from the back. This will cause a counter-clockwise glide. Reverse the lean if you are left-handed for a clockwise turn.

it could be that your airfoil is comprimised...

Ya, ini luar biasa!

That was CA Glue Accelerator. It’s a special liquid that helps the CA Glue cure almost instantly. You can find it in your local hobby store and online.

@@NighthawkGliders awesome thanks! And we need more videos, they are really good vidoes! And where is this 18inch sandpiper template?

I was so lucky that the glider realized it was not ready and returned to me for more needed trims so it can give us a spectacular show. What an amazing flight! 😊

@@NighthawkGliders It went really well! Where can I find plans for the Sandpiper 12"?

@@NighthawkGliders Thanks, I bought the plan. :)

Maybe, but turns more heads than electric 😂

I’m sure you have seen many of planes catapulted into the skies on the HMS Ark Royal Aircraft Carrier. That’s cool! 😎

Welcome aboard! We hope you have a great building experience with your grandson!
