Mike Helsel and the Sundowner 50

The Sundowner 50 ARF aircraft kit available from your local hobby retailer.

This plane is simply fantastic !
Dub's first comments: "It flys like a 120 mph pattern plane!"
Performance and speed... well....
See images below of level flight passes through the radar.

The Jett team utilized the existing air-cooling provisions intended for electric power
and incorporated a sleek, effective and aerodynamic Jett muffler installation.
Exhaust exists the fuselage side through a metal tube diverter.
Muffler installation required only a small spacer to adjust the muffler into the fuselage.

This aircraft also utilizes a Bubble-Jett fuel tank to ensure superior fuel delivery.

When ordering a 60LX engine specifically for this plane, PLEASE note that on the order.
The correct exhaust spacer will be provided.

The SJ-60LX engine installation - simple, neat, and effective.
No compromise - no loss of performance!

Note the needle valve location - Universal Needle can mount pretty much anywhere

The exhaust exit located on the side of the plane.
PLEASE NOTE - this rubber diverter did not work well.
It was replaced by a light weight aluminum exhaust diverter - visibile in photo above
(Also of note, others using this method have chosen to exit exhaust through the fuselage bottom)

Here you can see the required cutouts on the F1 bulhead and the internal structure

A shot from the bottom up showing the small cowl cutout required

So how does this perform ...... ?
Level flight passes through the same radar gear Jett uses to test the racing setups

Props used for these radar test passes ranged from a
9x7 Zinger, and also 9x7 and 10x6 APC props

If you are not reluctant to do a little bit of work on this wonderful ARF aircraft
The SJ-60LX can provide the performance, speed and reliability you are looking for!
