Inspired by the continued existence of a AA consuming toy fan from the 1980's, it was time to build something more efficient with RC parts.

Dumb Blond hottie

You wouldn't believe how hard it is to make a fan. The mane problem was noise, which RC parts aren't designed to avoid, but which is a critical design feature for appliances. The other problem was safety. A prop saver did absolutely nothing. The prop still shattered in an obstruction test. This is 1 area where 3D printing a shroud would be useful. For now, a wire provides some minimal protection from accidentally coming in from the side.

Greetings again all,

It's been a while since I've posted anything build related. I have to get on this one now because that cat's already out of the bag on another thread.

I don't really remember why I chose this for my next project; I think part of it was wanting to have something new and fresh to take to Ace In The Hole in Vegas.
After the long and drawn our P-38 project, (which is grounded due to a faulty nose gear) I wanted to do something a bit more fun and less bogged down with scale details.
I also had a break from work so I wanted to tear into something with a rapid building technique, fan fold or something like that.

I know the Zeta Sciences model is out there. I've had the good fortune to fly one thanks to my buddy Tony, (RCG member xplaneguy). That model is great, a real treat to fly. Lots of fun!
For me though, it doesn't quite capture the spirit of the movie version. Let me nerd out for a second and use a reference that most of you will get; it's sort of like the Scout Walker to the AT-AT, or Mini Me to Austin...

I also felt ready to attempt my first scratch build. I've been in this now for about 4 and a half years and think I've acquired enough info and experience building to try it out. I mean with guys like J Morgan, pmullen503, Sparks, Greenseaships and many others sharing their amazing techniques, I've got plenty of outside knowledge to lean on.

Now about the bird; I am going to refer to it as the Raiders wing. I know the other one is...Continue Reading

It's about time, huh?

Fully capable 32 bit board with baro and mag. Runs Baseflight, Cleanflight and Harikari beautifully. You might also have heard of these as Flip32s, but the DragonFly is here to stay!

These boards look awesome. Pick one up now at multirotormania.com!

Hello everyone.
Just so that you all know, I am new to RC Planes, I know very few about them, but, I've decided, that I'm going to start making my own plane. I am from Europe, so I might start building only after a month or so, because shipping of the parts here, from America and China, takes time.

My plan.
What I want to build is a sort of like WW2 looking Plywood Fat Bomber plane.
I am going to build it twin-engine, with 2 ESCs, 2LiPo's, ( Maybe 1 really good LiPo )
and I am thinking about making a section of the plane, where the doors underneath will open and drop something, when I press a button on the controller.

More indepth.
I am thinking of putting 1x Turnigy Aerodrive SK3 620kv engine on each wing of the plane, so that's 2x Turnigy Aerodrive SK3 620kv in total, with around 1600w of power on the paper. I am planning to put 1x Turnigy Plush 60amp Speed Controller on each engine (2x ESCs in total). Google says, that Aerodrive SK3 620kv loads 48A tops, so I think 2x 60Aamp speed controllers will be enough to handle each engine, and keep as cool as possible.
Please do note that I am not interested in speed of the plane, I am interested in making it sort of like elegant, smooth, with enough torque, but not with incredible speed or so on, I just need a lot of torque to get this plywood plane into the air, I am not interested into stunting and doing incredible Gs and so on. ( That might hit me, after I've finished this plane )

So, this far I've planned only what am I

Hey everybody!

Long time lurker... thanks to everyone for all of the information and cool stuff happening here.

I'm in the extreme early stages of a project that's been in my head for a bit. It's an ultra mini "racer style" H quad that measures just over 167mm (6.57in) diagonally motor to motor. The 250s are small but I'd like a bit smaller.

Attached are some CAD snips of the general layout of the base. I have 2 styles in the works; one where the arms and bottom plate are one piece, and one with a separate base plate and arms pair. A setup with 4 individual arms instead of 2 pairs will come later.

The base plate design needs a lot of work at this point but I need to decide on equipment first to design holes and cutouts around. Next will come the top plate which will sit probably 30-35 mm above the bottom plate I'm guessing. I'd like the arms to be held on with just 2 x 3 mm bolts then the rest of the body assembled with 3 mm nylon hardware. The size of this craft will necessitate the use of a board with the 30.5mm mounting pattern - leaning towards a Naze 32.

The arms right now are designed with a 12 x 12 mm bolt pattern to pair with the 1306 sized motors along with 3.5 inch props. This may be changed to 4 inch but we will see; I'd like smaller

I have on order some RCX 1306 2300kv motors and a plethora of 4045 props from myrcmart.com. My idea is to trim the props to 3.5 inches to see how that works-please tell me if this is a stupid idea.

I...Continue Reading

My original plan was to maiden the Beaver on wheels then switch over to floats took a little longer than anticipated to pull off. Almost a month after her wheeled maiden I got tired of watching my buddy Todd fly his Beaver off the lake and October 6th, decided to go for it (procrastination is my middle name)! The conversion to floats was pretty easy and straight forward. I forgot that I had added a bunch of 'up' trim during her maiden and after flying his Todd recommended using full flaps for the take-off. Well, the combination made for an very interesting first flight, she was still pitching up with me trying to push the stick forward out of the gimbals and in my efforts to regain control I had forgotten to retract the flaps and reduce the throttle! Well after about 40 seconds (that seemed like an eternity) I was able to settle down and enjoy the rest of the flight. Prior to this I'd only had a flown a couple of flights with my FunCub on floats at a float fly at Camp Far West. I've flown multiple flights on four occasions since the maiden (including one a bit after sunset) and the plane doesn't have any bad habits, the first couple of flights the landings were a bit hot and coordinated turns took some getting used to but the plane just fly's great! I've been trying to cobble together a video and I spent three plus hours on Windows Movie Maker last night on a 4 min 10 sec long video, getting everything just like I wanted it and when I went to publish it (that's what...Continue Reading

I lost my Radian. The wind blew it away in August. I watched it go down over the horizon when I couldn't fly it home. Every time I applied power it would just get further away. Hopefully I'll find it after the leaves fall off the trees.

Gentlemen :

I rewired the hand crank flashlight unit's guts to upgrade its servo motor driver from a micro servo one to the heavier Futaba one as the micro servo driver was straining under load . I found that an old Futaba FP-S128 servo had a driver board circuit that would work for this larger motor of the flashlight guts . Heavier output transistors used in the Futaba for the current needed . I had expected this result but wanted to verify it once and for all .

The rewiring of the servo for this unit was no big deal to accomplish . A simple stripping out of the original servo motor and extending the motor leads for the new unit was all that was required . A 15 minute job . I noted that the Futaba output circuit employed a pair of .01uF ceramic capacitors on the motor leads to the motor case ground and decided to keep these for the new motor . These caps are in the circuit to prevent motor commutator noise from getting back into the servo amplifier . Salvage these guys for use with the new motor and install them as shown in the pix .

The testing of this device was done on the bench using my servo tester as the signal source . I set it to its middle , neutral position and used my fingers to adjust the feedback pot with an attached servo arm on the servo itself as usually installed . As the feedback arm is adjusted from the neutral position , one should see a gradually increasing motor output speed in one direction . Moving the feedback arm the other way slows...Continue Reading

Well after receiving a replacement X mount an motor, installed that to the letter, when first spun up bearing noises straight off the bat, seriously these people cant be serious , anyway went for flight one ,appears all ok, how ever on flight 3 we have the same issue the X mount has broken in 2 places but again, after removing the motor the screws that secure the X mount to motor are still there an this time the field wiring has melted like fused together not impressed , putting in claim number 2,

So ive had this plane 3 1/2 weeks an flown it 5 1/2 times , i m interested to hear from anyone else that has come up against this issue , please feel free to give your 5 cents worth cheers

Btw prop is balance all screws are tread locked motor wiring to esc wiring is zip tied together, running the 4s setup with 5x5prop
