Designed as a small trainer, the Robbe Parat is available in several versions: IC or electric power with a built up or foam wing, the latter using a material called 'Siros', which is very light and has a spongy feel to it, although it is very strong. The model presented for review is the three function version supplied with Siros wings.
Kit Contents: All materials for construction are accurately die-cut from sheets of balsa and ply, just needing slight assistance with a sharp knife to remove them. Ample strip is provided for the fuselage longerons as are the wing leading edge strips. Included in the kit are all the materials for the actuating of the control surfaces (snakes, inner cable, horns, quicklinks etc), preformed wire undercarriage, wheels and collets.
The wings come packaged in heavy polythene and are very well veneered in 1 mm balsa. Included with the wings is tape for their joining.
To complete the model you will have to provide adhesives, covering materials, fuel tank, engine and radio. An excellent instruction book with stage by stage building instructions supplemented by photographs, an exploded view of the model and full size plan are included as well as a list of items required to complete the aircraft ready for flying.
Construction: The position of all formers, etc are marked on both fuselage panels and the longerons and wing seat doublers are glued into position. The formers are built onto the bottom sheeting to produce a jig onto which the fuselage sides are added. The nose end is now built upon the fuselage using the plywood engine mounting plates to obtain the correct position for the nose blocks and nose ring. Finally the sides are joined at the tail and the rear top and bottom sheeting added. The wings were joined using five minute epoxy and the leading edge strip added then sanded to correct profile. With the wing tip sheeting and the reinforcing bandage added the wing is completed.
Tailplane, fin and rudder are taken out complete from die-cut sheets and just require a light sanding to com-plete.
The review model was covered in blue solar film with red trim, the set of transfers provided in the kit were used as depicted on the box top.
For this review an Enya .15 was fitted and as I had just obtained a new set of Sanwa Club Series radio this was used, positioned according to the plan. With everything set up to fly the model was balanced and came out exactly at the point shown on the plan.
Flying: The first flights of the Parat were from rough pasture and required a hand launch. The model climbing away on full throttle requiring no alterations to the trims and was flying virtually hands off from the start, loops, stall turns and rolls (very barrelly with three functions) were tried and the model performed all impeccably. Landings are very simple, just ease the power off and she floats down nicely rolling to a stop. On the next outing at the Club strip the Parat rose off the ground easily requiring very little rudder to maintain a straight line.
Summary: The Robbe Parat TF is an excellent introduction to radio control model flying and is a fine model for taking it easy with. It is compact, lightweight, requiring only a small size relatively cheap engine and three function radio. I only found one annoying aspect to this model and that is the fixing of the fin to the top of the fuselage sheeting. On the plan this is shown as a butt join which I thought was very vulnerable and I resolved this by pegging it through the sheeting. For someone wanting a model in the air quickly the Parat took me just a week to complete including a couple of evenings AWOL."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
