About this Plan

Veron Robot (Radio Robot). Radio control sport trainer model.

Quote: "Designed as an easy to build, inherently stable, robust and dependable trainer for single channel radio. The Robot has been designed as an easy to build, inherently stable, robust and dependable trainer for single channel radio.

An ideal and compact size of 45 in, its design gives maximum wind penetration when powered with 1.49 to 2.49 cc (.09 to .15 cu in) diesel and glow-plug motors, yet amply big enough in wing area - 400 sq inches - to carry up to practically all the present single channel circuits for rudder, elevator and engine speed control and up to 3.5 cc with light multi.

With single channel radio receivers, 2 position engine speed control (with suitable 2 speed carburettor or exhaust choke) can be operated by a 'quick blip' of the signal key..."

Update 8/4/2023: Added kit review from Aeromodeller, Jan 1980 (RC Sport Flyer column), thanks to Aeronorm's post on HPA, see https://www.hippocketaeronautics.com/hpa...

Quote: "RC Sport Flyer, by Chris Pinchbeck. Veron Robot: Probably one of the earliest designs still available as a kit, this radio control trainer was originally designed as a single function, rudder only model. indeed, the plan still gives detailed instructions for installation of a rubber driven actuator to oper-ate the rudder. Nostalgia is also created by the instructions to provide trim tabs on the wing trailing edges and the provision for adjusting the angle of incidence on the tailplane.

Since most present day beginners will be advised to purchase two or three functional proportional radio gear, with in-flight trimming facility, the above items are not really necessary. Provided of course that the model is built accurately with the centre of gravity in the correct position.

The kit includes the necessary wood of good quality, preformed undercarriage and wheels, a detailed plan and instruction book. A supply of various nuts and bolts are included together with tissue for covering. Engine mount and tank must be bought separately to suit the power plant to be used.

The most unusual feature of this model is the butt joint between El and the engine compartment. This would act as a 'knock off' sheer plate in the event of a crash, hopefully saving engine and the rest of the model from further damage. The rest of the model is entirely conventional in construction and no problems were encountered during building.

The fuselage of the review kit was covered in nylon and the wings and tailplane covered with heat shrink film. The model has been subjected to some quite heavy landings and so far, has proved to be very strong.

Fitted with Futaba Medallion 3 plus three FD30M servos and a PAW 19 R/C engine, the model weighed in at 2 lb 15 oz. Control movements were set at ±3/8 in rudder and ±5/16 in elevator.

Attempts were made to fly Robot off a grass strip but owing to the length of grass to wheel size ratio, she ended up with her nose buried quite firmly into terra firma. A hand launch was used and with the engine on full power she climbed away into straight and level flight.

The inherent stability, so important in a trainer, was tested and once trimmed, the model would fly hands off, ie no interference from the pilot's transmitter. Robot was put into typical 'pause' attitudes to simulate the problems which might face a learner and regained her composure into straight and level flight upon release of the sticks.

At one stage the engine cut at altitude and rather than descend, the model appeared to ascend. Thermal soaring is not usually associated with this type of model but the wing loading is such that power off gliding is long and flat, with full control response being maintained throughout.

Conclusion: Comparatively easy to build although the plan and instructions should be updated. The model is very stable and easy to fly and should give little trouble to a beginner. One of the less expensive kits to be reviewed."
