The Allure Bipe is one of Bryan Hebert’s latest releases. It features a full Composite fully painted construction and is available in EP and GP formats. The Stabs are the same as used on the Alchemy as is the undercarriage.
This model is actually a pre-production version so I expect there to be some issues to overcome. I’ll detail the issues found during the build. The production model will have these issues addressed.
One of the first things to be done is to check the model for transit damage. Yes, transit damage does happen occasionally. Unfortunately not all handling from the factory to the dealer or Customer is appropriate for the goods contained in the box. Fortunately the factory takes great care in packing the models to minimise the risk of damage in transit.
Like other CK Aero models, all components come packed in protective bags. These can be used to store the parts when the model is finished to prevent hanger rash. The carton is two thicknesses of 10mm cardboard with appropriate doublers, compartments and braces inside.
The visual condition of the box is normally a very good indicator of the condition of the contents. If the box is undamaged then more than likely the contents will be intact. If you see external damage like holes or crushing then there’s a possibility that the contents might be damaged. If the packaging does show signs of damage take pictures before opening the box. All of our imports, exports and domestic shipments are insured. For this reason it’s important to check the goods upon receipt and report any damage immediately.
Once we’re happy nothing is damaged, the model gets some basic checks before assembly starts:
Finish - We check that the paint finish is of acceptable quality. You might find traces of buffing compound on the finish. This is easily removed with a micro fibre polishing cloth.
Fit - We check that the basic fit of the components and build is of acceptable quality. Sometimes some small adjustments are needed.
Straightness - We check the straightness of the elevators with a CK Aero Precision Elevator alignment tool. Other checks are done during the build process using a precision incidence meter.
Weight - This is super important for F3A models and particularly with a Bipe of this size. All airframe components including the undercarriage legs and wheel pants are weighed. The accessories are not weighed as these may or may not be used in the final build.
With this build the component weights were:
|Fuselage, Chin Cowl & Canopy||1087 grams|
|Undercarriage Legs (pr)||88 grams|
|Wing Struts||47 grams|
|Wheel Pants (pr)||27 grams|
|Left Stab||104 grams|
|Right Stab With Tube and Adjuster Pin||123 grams|
|Top Wing||521 grams|
|Bottom Wing||543 grams|
With the airframe weight being 2535 grams component selection will be critical to make the 5000 (5050 grams with 1% tolerance) gram limit.
I find it helps to make a spreadsheet listing the airframe and equipment weights to project what the final weight will be approximately. With a Bipe this becomes imperative!
