Glad to share my experiences with those who inspired me along the way. We're a hobby with no secrets. I appreciate hearing that u enjoy these films. More to come as time allows.
it is a learning event to see how your model flies then directly how you trim it. then to see it fly after your careful report on the modification is so edifying. three or four of these trim sessions often results in a glorious climb aided by thermals resulting in a tiny model so high it would be scary if i had control of it. you work magic and it is beautiful to watch!
Your modes are amazing and the videos are super informative. I never realized how capable rubber powered free flight is!thanks
I can finally understand the satisfaction - thankyou
I’m really enjoying your new trimming videos! Thank you for giving a bit of narration to what you’re doing and why. Helps me sort out trimming my own models. Take care!

Thx. I'll admit that my observations & fixes are not always right, as with trim session #1, but it helps to have others watch on the field (or here) and give their spin on what's happening. With so many options for trimming our birds, I just go with my gut in the moment, and hope it works out. In this case, moving the CG forward was the key. Basic lesson learned, again. Ha.
Odebírám a sleduji. Je úžasné, co tento druh pohonu dokáže, když to někdo umí a zná. Krásný den.

Thx, Bob. The Spartan was one of my late mentor's favorites, so I couldn't resist building one. I love the bird's stylish looks, especially against the blue.
Your videos are my field of dreams! Thank you.
13:25 - 13:30 is the money shot! More slow motion launches please! The early morning flight is gorgeous too!
Just listen to the free flight sounds ! Birds and rubber motor !
Your videos soothe my soul. Thank you so much.
Sublime and inspirational.
Your videos keep getting better and better, The camera angles, and scenery along with the music make your videos a work of art. Thank You for taking the time to make them. They are a joy to watch.
oh max.. simply superb...
Hey, Tom. I tend to hold back on watching your videos until I feel it's time to, "calm the mood," so to speak. This is one of those times...
Thank you for sharing this....
Such a beautiful plane, thanks for the great detail on your trimming adjustments. Again a great looking plane, great job!
The slo mo ROG was a great shot! Are you sure having that much fun is legal? Thanks for posting. I learn a lot from every one.

Tom is fortunate enough to have the skills, talent, and resources to build models not found in kits. Virtually the entire world of aviation is at his fingertips. I'm just glad there are talented people like Tom so we can marvel at their work.
Exquisite!

@@maxfliart Thank You. If I ever build a larger plane this will come in handy.
Aspirational!
Great video! It is very impressive to watch the progression of flight from the first video to the second! What would be a good airplane to start with? One that would be fairly easy to build and one that is easier to trim. I would really like to build one!

Thank You!
I’m curious, do you ever build in movable ailerons, or trim tabs in their place to make modifications to your turning flight pattern, as opposed to adding weights to the wingtips? Perhaps the additional front spar on the aileron and hinge material would end up weighing more, anyway? If you’ve done it on a previous video I haven’t noticed it yet. Edit: I should have begun this with complements on the beautiful model.

Thx for the feedback. No to ailerons. I did it once for a 37" Junkers J.1, and it only created problems. I prefer gurney flaps, which remain constant, vs anything hinged or trim tabs. Each gurney flap is a subtle adjustment but it works best for me.
Not enough " O's " in Smooth, for that first ROG flight!
How is the dt? triggered? Beautiful flights amazing what rubber power can achieve.

It's a dethermalizer. The process where the tail pivots to 45º via a timer, bringing the model down, out of a thermal. Article on dethermalizers (DTs): @t
Too breezy for me to fly today- but I can walk along side you and silently help trim your model...Thanks for posting! With those changes, this one flies as well as it looks like it should! Beautifully shot too.
