This is an impressive and well-designed F3A aerobatic pattern-ship constructed from super tough EPO foam (which can be glued with cyano & kicker). The foam has a smooth gloss-like finish which makes it more durable and streamlined than other foams used in model manufacturing.
This fully aerobatic model has many interesting features and suits a wide variety of power sets depending on your experience and expectations of performance and duration. A standard undercarriage is included but – unlike similar models in this class – the Rainbow wings are moulded to accommodate light weight retracts.
This version is part-built with much of the tricky work done – the wing tubes and control snakes have been installed and the wood parts glued in place – including the motor mount – so the build is very quick indeed.
Designed for 4S to 6S (14.8V to 22.2V) LiPo with overall capacity ranging from 2500 to 3300mAh, the power requirements range from 800W to 1300W – from the new, low-cost EMax GT series brushless motors to the Hyperion or Scorpion 4020 size. The model is easily converted to IC but with all that oil and fuel residue flying about, you may want to consider applying a light-weight glass coat to seal the foam and joints.
Features:
* EPO aerobatic pattern ship (F3A) design
* Stable flight characteristics
* Fuselage T canaliser (the small wing on top of the fuselage that helps to smooth airflow going over the top over the model, before it reaches the rudder.
* Detachable wing for ease of transport
* Steerable tail wheel
* Removable canopy/hatch for easy battery swap
* Generous battery compartment allowing Lipo power from 4 to 6S. If you only have 3S packs, you could use two connected in series for a 6S setup.
* Factory installed motor mount
* Requires assembly

Because we can never resist the excitement of opening big shiny boxes and adding a new model to our range, we examined this kit in detail to determine the power requirements and what other items are required to get airborne – obviously at reasonable cost!
Our recommended power set up based on 4S LiPo operation together with ancillary items is as follows:
* EMax GT 3526/04 brushless outrunner motor (404640)
* 80A Pro ESC (400217)
* APC-E 13 x 6.5 prop (411455)
* TowerPro SG5010 standard servos – 4 required (406118)
* 15cm servo extension leads – 2 required
* 5A U-BEC (400247)
* 3000mAh 4S(14.8V) LiPo (405062)
Make no mistake – this is an impressive design sure to please anyone with intermediate-to-advanced flying experience.
