That plane looks a lot like a Kadet Mark II kit that Sig sells for $90. It was my first plane some 30 years ago. Nice flyer and an easy build. Have fun with it.
Just looks like extra work to me Connor, and for little benefit. If I have a long control rod 'travel' I simply 'sleeve' the middle section of the control wire to mitigate any deflection / sag. The way you have done it, you have introduced two further potential fail points at each of the metal to wood connections - I am an older flier but with modern techniques and available components, you just dont need to use the old school ways!
Why aren't your pushrods simply all metal? do they really bend? I'm new to this and this is the first time I see a wood dowel in the center of the pushrod.
It's as per the plan. Using balsa would help prevent flex of an unsupported metal rod. Is an old method of connecting servo to surface, There are far better pushrods on the market. But it's interesting to see how things used to be done.
I see a bunch of people using hexatronic, from Hobby King I am guessing? I also see Towerpro servos around alot. Are they comparable to hexatronics, better, worse? Are there any 9g servos brands to avoid? My real bet is that they are all just rebranded? On a separate thought... I am nowhere near a RC engineer nor would I even pretend to be as knowledgeable as Conor but IMHO putting a bend in any type of control linkage I would say is a risky move. That being said piano wire is no joke, it might hold up.
This way of installing servos is old skool for sure. It's perfectly suitable for small light planes so long as the bends in the wire are shallow and kept to a minimum. It also avoids having to put in additional formers down the fuselage to mount guide tubes (thus keeping the weight down). Bigger planes will certainly need more robust pushrod solutions.
I have used guitar string on my pattern planes. However my setup was pull pull for both elevator and rudder. The plane in this video would work fine with push rods available at most online RC hobby stores.
John Anthony Clark Hi, I got them free in the May 2015 edition of RC Model World magazine(gb.trapletshop.com/rc-model-world-may-2015). The plans are available to buy here: gb.trapletshop.com/millie-bob-plan
Hi, as it's a small and light model the pushrods are thin and could flex if they run the whole way (especially as they are unsupported by tubes or guides). So I use hard balsa to provide stiffness over the length. It's only one way of installing pushrods, so if you're building you can use any method you prefer. 😃
Hi, yeah you're right but the servos are up to it. Plus, the balsa reduces the flex in the length. It's old school solution and control rod would also work, just wanted to follow the plans and get back to basics!
+Nathaniel Ihenachor hi, the push rod is made from balsa strip and 1.5 mm diameter wire. I bought the wire off eBay, but I would recommend using threaded wire and clevices to make the connection easier.
@@StartingOutInRC Also, balsa is lighter than metal wire. Everything behind the C.G. must be kept as light as is practical. For every gram of weight in the tail, it takes 3 grams of weight in the nose to balance it out.

Hello Conor all looking good .Keep up the good work .Looking foward to its 1st flight.Tony Wright.
Thanks Tony. Getting closer, I just need the DIY to slow down and the model making to speed up!!
Great video...we found it very helpful. Thank You!
nice video! lots of work, but well worth it for a good outcome!
+Brian Phillips thank you!
Great build!!
Good video
This video helped me so much thanks
Can you please share the link to the push rod, any information on where to get this kind of wire online (amazon)? Thanks for your videos.
Great work .. Do you have a video flying it?

Hi do you have any up to date plans I can use to build this please?
Hi, you can still get the plans here www.sarikhobbies.com/product/millie-bob-plan/
I saw that but is a bit too expensive, do you have this plan pdf that you could send me or not?
Hi, I don't have it as a PDF. That site is the only source I know for the plan.
Ok thanks anyway though, your builds look amazing and the videos are great, keep up the good work!
Thank you.
Where can i get pushrods and could i use guitar string
Pushrods are available from your local model store, or online model shops. Guitar string wouldn't be up to the job.
@@StartingOutInRC thanks so much for ur help
I have used guitar string on my pattern planes. However my setup was pull pull for both elevator and rudder. The plane in this video would work fine with push rods available at most online RC hobby stores.
So fascinating
Hello Conor
Great work ! , learned a lot
But from where did you get those servo pushrod ?
Thank you! I can't remember exactly where I got them, but it was from an online RC store. Search for piano wire or pushrod wire on RC online stores.
Where can I buy the plan for this plane or can you send me the plans thank you

Conor O'Neill ok, thanks 😀
Conor O'Neill also, I'm quite new to all this. Do you know of any free plans that would be good for beginners?
Hi, a good place to start is aerofred, and filter there for trainer models. Plenty to choose from.
Conor O'Neill cheers!
You seem to have given the servos extra weight to move in using balsa instead of just control wire
Hi, yeah you're right but the servos are up to it. Plus, the balsa reduces the flex in the length. It's old school solution and control rod would also work, just wanted to follow the plans and get back to basics!
Wow nice work!! Can i please get a picture of the planes plans? Please.
Can we use analog servo in rc plane
Yes, you can. I recommend you read this article to better understand how digital and analog servos differ: www.rchelicopterfun.com/rc-servos.html
What Pushrod Do you use?
Hi, it's 18 SWG piano wire.
And if you need to adjust the push rod further then what your radio allows, your out of luck. You need an adjustable clevis on one end.
Hello Conor, where can I buy the push rod from please? or what is it called.
+Nathaniel Ihenachor hi, the push rod is made from balsa strip and 1.5 mm diameter wire. I bought the wire off eBay, but I would recommend using threaded wire and clevices to make the connection easier.
which airplane is this?
Hi, is a high wing electric trainer called Millie Bob. See ua-cam.com/video/p6aLyVwkqAo/v-deo.html
What kind of motor did you use for this aircraft?
It's a Turnigy D2822/14 brushless motor.
Conor O'Neill thnx
Why use balsa in between?
Hi, wire on its own will flex along its length as it's unsupported. The balsa adds stiffness along the length of the pushrod.
Conor O'Neill what about a thin piece of balsa with 2 small holes to serve as guides and support for the pushrods?
@@StartingOutInRC
Also, balsa is lighter than metal wire. Everything behind the C.G. must be kept as light as is practical.
For every gram of weight in the tail, it takes 3 grams of weight in the nose to balance it out.
