Using EC3 connections on my quad was a good idea...except when it applied to the AttoPilot 90A sensor from SparkFun. The goal for adding this sensor to the system was to be able to remove it cleanly if needed. The sensor pcb design was…

It took me a little while to learn what most of the switches and buttons on my DX6i could do. This past weekend the Trainer switch was assigned to start the timer in a count up mode.
Behold!
With my EFlite 30C 11.1V 3200 mAh battery almost 7 minutes of mostly hovering flight was achieved (no…

It was a busy weekend. One of my earliest concerns with this project was the lack of an ON/OFF switch that could handle the current of the system and that would not look like something from an old junk box. I wanted it to be easy to use, easy to access (translate: no where near the propellors), and completely…

Carl La France said… Quit a project you have going! I never seen one of them fly in real life. you are right into it.After a while it becomes an extension of your self "Good Job!
" Education" begins the moment you are born and never ends ."" The shortest pencil is better than the longest memory" I was always a believer in the 3 book theory ! You read one book on a related subject by a particular Author you are a Clone ! You read a second book on the same subject by another Author you can see a difference !You read the third book on the same subject by a different Author You can formulate your own Decisions ! The guy that wrote the first book doesn't know what he is talking about and if you only read one book you are a Clone.
Since I am from the "Old School " I learn by mistake! I do every thing twice . I just get right into it doing it wrong the first time which is good practice so I can do it right the second time ! have a good day

Carl La France said… You have a lot of experience in RC I never seen mini servos before the Radian Pro I got a special on regular size servos from planes from the past We put everything inside back then and they flew well . I like the way you sketch things out taking advantage of the space available my radio is a 6 Di by using one servo for the ailerons I free up the aux channel for the camera The work you do looks quality ! have a good day!

Carl La France said… R .D. go to my page and check out my posted photos ! I am going to try and get the wing together this week end . You are working with new to me technology On your Quadro rotor how do you sinc each motor to run at the same rpm ? I t must be a pretty good balance to get it to hoover stationary it looks pretty big how far is it across ?when you are 20 feet away how can you tell the front from the back?have a good day!

Carl La France said… R.D. I have a quad on my real flight simulator and I can't even begin to control it after looking at your pictures of the inside of the Nova I like the way you routered out the foam and made a basket for the servos . pretty precision stuff. Impressive you might be working to closer tolerances than me because of the stuff you want to put in and the room you have available. I jigged up and laid up the ribs for the wing on my drone today my buddy has a ping pong table in his garage that belongs to his son he never uses it it has become a work bench I screwed the jig to the table to keep the wing straight From the drawing to cutting the pieces to laying it up is quite a change after looking at it full scale it is kind of "High aspect ratio " There is a lot of pieces and it took all day I c/a ed my fingers together many times at one point when I was about half done I thought "Why am I doing this? I am old I should be sitting on a bench in a park some where enjoying the weather watching people walk their dog then pick their dogs crap up and put it in plastic bags!" I will get my son to take a picture of the wing over the weekend and Post You have a good day! Carl
Carl La France said… R.D Do you have any experience with pusher prop stall and spin recovery where the motor is right on the tail? I am concerned Gyroscopic procession might make it impossible to recover if I put the motor there Thanks Carl
Carl La France said… I didn't read any thing on it I was going from practice experience in a large plane .Spin Recovery Verify ailerons are centered , opposite rudder to stop the spin elevator forward to break the stall pull out of the ensuing dive altitude loss 150 to 700 feet depending on the skill of the pilot . I don't know about a rear engine plane ? Just guessing in a full scale drone like the raptor that is rear engine since they are not in the plane they probably need 500 feet to stop the spin and another 400 feet to pull out of the dive
My concern is if I build a rear engine
RC plane and I only have 100 feet of altitude and if it goes in to a spin if I would be able to pull out or would the torque from the motor make it impossible to fly out of it? and increase the spin rate? right now I am looking at all the options as to where to put the motor other than on the nose Thanks Carl
Carl La France said… R.D. Thanks for your comment I have been including the drawings with my posts as I make them up If any body wanted to make their own they could I am inventing as I go along same as you with your Quadro rotor One of the reasons I have an aluminum tail With the Spirit glider I have the tail broke nearly every time I flew it You have a great Day! Carl
Carl La France said… R.D. I left a comment for Robert Pigeon on his comment wall with some pictures check it out he means well and is a good guy .I am rebuilding for the EDF wait till you see my next post next week!
Carl La France said… Bam! and they walked away Thanks R.D,
John Githens said… Doug, (I am still adjusting to the design of the DIY Drones site... not the best from my experience with wikis and blogs.) Below is a reply to your comment. Not sure if you would have received an alert that I left one in the other location.
Thanks for the offer and the tip about keeping a log sheet. I bought this charger from progressiverc because of some favorable blog mentions (and they are conveniently located in the basement of a house a few miles away from our home). Based on meeting those guys, I have a high trust for their advice and products. Haven't looked at these pages. I am about to *carefully* charge my first lipos with a charging bag.
Season Two of the Trust Time Trial (T3) Contest has now begun. The fourth round is an accuracy round for multicopters, which requires contestants to fly a cube. The deadline is April 14th.106 members
