a superb electric model

Designed from the outset as an easy to build all balsa model Croosfire manages to combine smooth good looks with an exciting electric performance for the flyer who has progressed beyond the primary stages and can fly simple aerobatics.

Crossfire is very clean and efficient with a special airfoil designed to extract the maximum performance from low cost electrics and will fly happily on a range of electric motors ranging from the cheapest 540 to the hotter types like the excelent Monster Truck 550 by Kyosho.

It is quick and very smooth, large open manoeuvres are easy yet I was unable to stall the prototype at 40 ozs with full up trim and stick from a level glide, a true Moonraker offspring!

It could be flown with only two channels for elevator and aileron leaving the rudder fixed and using and on/off switch for the motor.

The kit is very complete with pre-cut fuselage sides, die cut ribs, all balsa and ply, self adhesive cutting patterns for all parts, self adhesive coloured graphics and all hardware including motor mount.Electric flight is satisfying, exciting, and here to stay, with Crossfire there is no need for it to be be expensive as well.

Who will try it on the slope without the electrics, it would only weigh around 20 ounces all up?

It flies just great with a .10 or .15 i.c. motor (but needs some modelling experience to do the conversion which in itself is realatively easy).

The equipment we used in the prototype to achieve 8 minutes of contiuously powered aerobatic flight is as follows:

Kyosho Outlaw Stock Mega motor with Graupner 6"x3" folding propeller. 7 x 1400 Sanyo red SCR cells (charged from Westbury or Hitec Peak Detect chargers). MFA plugs and sockets. SLEC micro switch and harness (with brake). JR receiver, 225 mah battery plus 4 Hitec mini servos driving ailerons, elevators, rudder and motor switch. An up to date set up would be a Graupner 8x4.5 'cam' folder, 7x2000 cells or 8 cells for red hot flying.

A kit review appeared in the Febuary/March 1996 issue of Silent Flight.

Production status

As I am no longer making and selling Crossfire you will have to contact Pete Ross for your Crossfire at http://www.petes-planes.com/html/electric/crossfire.htm by telephone and fax on 01749 679739 or e-mail at pete(usual at symbol)petes-planes.com Peter has been a life long modeller and enjoyed flying his Crossfire so much that (like the electric shaver man) when asking about a replacement kit from me he started enquiring about producing it himself. Peter is already producing upgraded Crossfires kits with profiled fuselage sides.
