New Jet - Scott O'Quinn

New Jet came in today - Just waiting on turbine after overhaul.


Turbine Powered Delta - Keith Lindsay

Most of you have seen the large .91 powered delta I fly. I took it a step further and made one a turbine powered canard configured jet. The pictures show the sequence, sort of, as it was being built. The fuselage is about eight pounds empty, so should be about sixteen pounds ready to fly. The turbine is rated at fourteen pounds....should have adequate thrust for vertical performance. The canard is one third the size of the wing with the same sweep back angle. The canard elevator should enhance the elevons and provide high AOA landings...that's the plan. The CG was moved up four inches because of the canard. Two 24oz. Tanks are imbedded in the wing. A 4 oz. Hopper tankis located in the fuselage. The wing is sheeted with 3/32 balsa. A second spar was added for strength. A fun project that was easy to do.

Finished Spitfire - Mike Griffin

The Spitfire is finished except for finishing the leadouts. I think it came out nice. I used leather fillets and I really like them.

Flying King Project - By Keith Lindsay

Many of you know the Flying King designed by Bruce Tharpe. The model has been around a while and has been adapted to many different schemes. I thought it would be a great platform for a four engined model.

The engine of choice ( because I happened to have four of them) is the four cycle OS20. Actually two of them are .26s and two are .20s. The total thrust from the four engines should be about right for the airframe.

The nacelle spacing was determined by the size prop being used. The wing center section is flat so no dihedral problems to worry about. The size of the nacelle was determined by the fuel tank, throttle servo, and engine. Once that was settled, the nacelles went together quickly.

The fuselage nose was changed and the wing hold down plate and dowels were fortified because of the increased weight of the wing. Other than that the kit was built per directions. Because the model is being built in Germany I'll have to wait a couple of years before it can be mailed to Georgia. I highly recommend the Flying King, a very nice kit that flies like a dream and is an easy build!!
