Trimming the BAMF 2 DLG and Chasing Thermals
Вставка
- Опубліковано 8 лип 2021
- The BAMF 2 is an RC glider that rises in columns of hot air called thermals, and thermals are present even when it's cool and overcast! This is my third time out with my new Strong layup BAMF 2 DLG, and first time flying it in calm conditions. The elevator rates/expo and aileron differential still need some finetuning, but we're getting close.

What kind of conditions do you usually fly in?
All but dark, wet and windy. If I can get out for an hour, it makes my day. Quite happy to fly for two hours a day.
As a sport flyer who isn't preparing for contest flying, I can afford to be a little picky. If it's between 8 am and noon, and relatively calm, I'm on it. But when the conditions deteriorate, I stop!
I fly in the air
Windy and turbulence and in tight landing space, it's always much more fun this way! :-)
There are a lot of dlg flying videos available, but very very few with a useful commentary. I picked up some tips from this. Thank you.
Thank you, glad you found it useful!
Long time slope soarer dipping my toe into DLG and Loving it, very addictive, trying to get my head round reverse! differential. Love your channel, the information you share, and the tutorials, Thanks
I love it, glad to help and welcome to DLGs!
Great flight Anna thank you
Glad you enjoyed it ❤️
Great video. The lack of rudder worked better than I expected. I liked how you kept telling us which mode you were in. Thanks!
Glad you enjoyed it! I think rudderless is sometimes misunderstood or has a stigma attached to it so I’ve been highlighting it a bit in my last few videos.
@@ArmSoar I watched your build video on this model, I seem to recall you having an active rudder.....is it an option or were they rudderless at the beginning and now you encourage building with a rudder?!?!? Sorry just confused.....looking to get back into chasing thermals after a 25 yr layoff...😉
I'm curios Tom, what's your favorite flatiron design servo placement wise? Linkage from boom to surface or wing impeded servo. I like the design of wing servos with the pushrod going through the wing to the upper part of the surface.
Thanks Thomas. The voiceover/comments make a huge difference to these videos. Spent some time watching this one on the large TV screen.
My speed once in the thermal is always much slower, bordering on stalling and my circles tighter.
Does this vary thermal to thermal? Higher speed more wing lift? Wider circles more speed?
Speed depends, I used to slow down my planes too much when in thermals. I find that flying them a bit faster makes it easier to control and less prone to outside disturbances. Circle size depends on the size of the thermal. Usually they're smaller down low and gets bigger as you go up.
Funny how you consider a 45m launch soft, those are some of my best launches 😜
Still loving my BAMF2, just need to fly it more often.
Where did you find/pick-up the streamer for your transmitter? On the 35 MHz antenna it was easy to install, but on the new 2.4GHz system I have not found one yet.
I just 3D print a mount for the back of the radio, then slide on a fibreglass rod with a streamer attached to one end.
Thomas, this is Kenny in Korea. I have been wondering about going rudderless myself. I think the advantages are loosing the weight of the 4th servo and control linkage and the simplification of flying? Are there some other advantages I'm missing? Are there any major disadvantages other than the obvious loss of yaw control?
I don't think weight is much of an advantage nowadays, you might save a few grams but nothing significant. Simplification of flying is the big plus for me. Takes longer to trim out the model nicely, but once it's trimmed and you understand how to fly the rudderless model, it can be quite simple to fly well. The other advantage is less gear/linkages so it's one less thing to go wrong.
The major disadvantage is the lack of yaw control as you said, so for very good pilots, you will lose out on some flight efficiency. You also lose some of the 'fun' of flying with a 4ch model as it's a bit dumbed down with rudderless.
One disadvantage that I've been noticing right now is because I'm flying multiple types of models now, most of which has rudder, it sometimes messes with me when I switch between planes because the way you enter and maintain a turn on a 3ch vs a 4ch is different. Never noticed it before since I used to only fly F3K.
Can u tell me the ailerons up and down relationship of your setup. Am i right with aileron down is 50% of aileron up?
There is more down travel and less up travel (reverse differential). For reference, in speed mode, I have 16mm up and 25mm down.
What is this additional thing called - for checking wind direction and speed?
It's just a piece of string on a fibreglass rod attached to the back of the radio. Endearingly called the 'wind indicator' 🤓
What is the difference between rudder and rudderless in regards to performance and ease of use?
Theoretically rudder should give higher performance, but I see a lot of people use it poorly and I bet it causes more drag for many pilots. Rudderless is harder to trim but once trimmed it’s easy to fly. Both works well, personal preference. Most prefer having a rudder.
@@ArmSoar thanks for the help!!
I'm just starting on dlg and I'm working out what to buy for me
@@ArmSoar I used to fly my 1m dlg rudderless and did pretty well, but since Ive installed a rudder it just doubled my performance!!
Did you say you had vario telemetry on an ar410?
No, no vario on the AR410.
Hey I have a question. I want to put a ar410 receiver from spektrum in my kite dlg. Am I going to have problems with the signal if there is no antenna ?
No, the AR410 with the built-in antennas is a solid receiver.
"A light throw, only 45m or so". :-/

拍摄时可以Zoom近啲部飞机会更好。
我手機沒發zoom那麼近，多買幾部飛機等我升級相機📷 😄
Thomas, just an this idea, let's make the same video with Anthony R thermaling ;-) ;-) and why not a camber up?
I’m looking forward to getting some stuff made with Anthony R!
Само да попитам, абе как мацката познава че има термика.🤔 И как така не ти дава инструкции как да влезеш в нея и в коя посока да се въртиш .😂
