Ultimate NAC

ModelarzyRC's Ultimate NAC

Here is my Ultimate NAC - Easybuild bipe.

NOTE: Please read all!

Following on from my other Easybuild park jets I decided to try a bipe, using a similar tab design.
I designed it a bit smaller so that I could leave it in the car boot just in case the weather is good on the way to/from work
It is built from 6 mm Depron, held together with hot glue. I only used Epoxy for the carbon rods.
I also designed it to balance with 1350 weight or 2100 weight battery's.

Depron = 6mm
Wing span = 84cm (~33”)
Length = 81cm (~31.8”)

Weight (painted) = 410g
Weight (painted with 1350 battery) = 554g
Static thrust = 670g
Prop = 10x5
Motor = 1050kv
ESC = 25A minimum
Battery = 1350 or 2100 3s1p 25C Li-Po
Radio = 4CH
Aileron throw = +/- 20 degrees
Elevator throw = +/- 35 degrees
Rudder throw = +/- 35 degrees
Expo = 50%
COG = 7cm from upper wing leading edge.
You can find tiled PDF plans (letter, A3, A4) and build pictures at higher quality versions here: https://www.dropbox.com/sh/04no5g6yqjv08xi/AAAE3gcXnZe55HmWRNkQHpOha?dl=0

I am using a HC C2830/12 KV1050 I think that it is around 58g. I wouldn't go any lighter on the motor.

2. Please make sure the stated wingspan is correct.

Important Notice:

If your orders placed during the COVID pandemic are delayed the reason is the reduced number of airline flights and your national mail service not distributing mail as it normally would, please ask at your local post office what is the delay currently, we just can´t tell you any better than they.

The feedback from US customers who ordered during April and May is that orders are being delivered in about one month and a half. If you ordered Priority mail you can use the tracking code I added to the Paypal transaction at the USPS (or any other mail service) website.

Order Queue:

Current queue for new orders of 3d printed kits is 2 months. (Starting on the 20th of June 2020)

For printed plans there is no queue. Prints are posted next business day.

This calculator will work on pdf and image format files, if the file is very large, 5 or even 10 Mb it will take longer to process the plan file, it may finish even after the button animation stops spinning, please be patient when calculating larger files.

Terms of Service.
Please read the Plans Printing Service Terms of Use before placing an order.

What are you ordering:

You are ordering a print from the main PDF file in this listing, it´s exactly like taking this file in a thumb drive to a local print shop and ask them to make a print.

About the plan source:

You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling. To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.
In doubt please ask us for an opinion.

Plans Scaling:

We can scale this plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.

You will receive:

  • Laser Printed plan on good quality Bond paper or/and Tracing Paper and/or Polyester sheet of the PDF file from this listing, depending on what you have purchased.
  • Rolled sheets, up to 5 in the same cardboard tube.
  • Envelope, up to 5 sheets per envelope.
  • Articles and Instructions if they are available and if you order them.
  • Air Mail, Priority, Priority Insured or Normal mail, according to your choice.

About our printers:

We use professional quality laser OCÉ and Canon printers/copiers, these printers use toner, not ink so the printings will be durable and waterproof.

About the different media types:

Bond Paper: White Bond paper, 80 grams per square meter.
Bond Tracing paper: Bond Tracing paper, 90 grams per square meter.
Polyester film: High quality polyester sheet incredibly durable, will resist cuts and glue and can be washed (I use it as sail material on my RC sailboats).


We charge by print length (914mm or 91,4cm or 36in. by the length of the print)
This means that a plan 120cm by 150cm will be charged two times 150cm because it will be printed in two tiles, a plan 91cm by 150cm will be charged one time its length or 150cm and a plan 91cm by 40cm will be charged 40cm.
The system will try to fit a plan in the 91,4cm of the printer width in order to reduce the costs or print length to the maximum. This is the same charging method used in any printshop.


We will use paper or waxed paper padded envelopes for folded plans and hard cardboard tubes with plastic ends for rolled plans, depending on your choice.


We ship from Portugal, Europe and use the reliable Portuguese mail system CTT.
CTT has delivery agreements with different entities on each country so if you´re from the US you may have your order delivered by USPS, in the UK may be Royal Mail and so on.
Orders are dispatched on the next or second business day after purchase.

Discount Coupons:

Discount coupons are valid from 3 to 30 days after purchase, you can use them any number of times you like but only once per item order.
The codes are issued in the Paypal invoice, please check the transaction details at Paypal website or in the Paypal email you received after purchase to get your Discount Coupon code.
You are free to post the Coupons online, give them to friends, share them in any way you like.
To use just Copy/Paste the Coupon code (i.e.: TAKE10#6012019) to the text field in the plan listing page to use your discount. No spaces and no manual typing, just copy/paste.

Please keep in mind that when you order a plan it will be printed specifically for you, just like when you go to a local print shop.
Before ordering please make sure that the plan will fit your needs, in doubt please ask us for an opinion. If you still receive a plan you don´t like we can accept it back if it is in good conditions but we will not refund the postage from the initial order, you will have to pay the postage to return the plan to us and a 30% re-stock fee will be applied so please, in doubt, please ask us for an opinion.
