Attached is my first “B” classic gas plane. 🙂 It’s a 585 Galaxie wing and stab on my own designed fus. Pwr. is an OS 25 FSR-S on pressure tank. Covering is Oracover, finished weight is 27 ozs. (770 gr.), probably on the heavy side but very strong. Initial test glides looked very good. Looking forward to test flights.

Very nice job. Did you lengthen the fuselage any? Looks like it should fly just fine.
Denny01/30/2009 at 3:30 pm #46974
Yes, lengthened the fus. 7 inches. Lengthened the distance from TE of wing to LE of stab 3 inches. Distance from wing TE to stab LE is about 2.7 times wing cord.

Always partial to Galaxies. They usually fly right off the board. Looks like a winner. Have you had any experience with the rear fin galaxie?01/30/2009 at 4:27 pm #46976
This is my first attempt at a rear finned Galaxie. I have a 1/2A Std. Galaxie that flys great. I’m going to build another with the wing and stab reduced to about 270 sq. in. and build a rear finned fus. for it. Should be competitive with either a hot TEE DEE or a stells that I have. Can’t afford the Cyclons.

Scott and I have ‘talked’ over the past few months while he was building his hybrid Galaxy. A very nice job indeed Scott.
My modded Galaxy was built 30 years ago with a lowered pylon, longer fuselage with a thick fin on the rear, and the outer polyhedral joints in one bay.
Engine is a Super Tigre 21/29 that would haul it into the cloud base at times.
It has VIT and Auto Rudder and hard tank on crankcase pressure for even running and flood off……also including a prop. brake.
It flew lots in the ’80s and I found a couple of times on a hard DT landing the wing collapsed so I built a spare never to be used. Did a strong repair job on the center section with CF strand Cyano’d on.
With the field situation here as it is I shall never use it in ‘anger’ again, and as I have a couple of people interested in some of my models, today I got it out for a pic or two……..enjoy. Hope I can get a pic on???????[/img]

Well, had to build a new fus.. The current one was not strong enough at the stab transition area and kept on breaking. Attached are pics of new fus. with all “C” grain 6-7lb wood and 1/64″ x 1/2″ x 6″ re-enforcements lamented to the inside of the fus. at the stab transition area. Fire wall to 1″ beyond pylon re-enforced with.5 oz. glass using Z poxy than sealed remainder of fus. with Z poxy. O.S 25 FSR-S for pwr. Finished weight is 24.64 ozs. (700 grs.). Will be test flying soon I hope!

Well got a short chance last night to start the trimming process on the Galaxie. First pwr. flight was great 😯 😀 Plane flew perfect right hand vertical spiral, transition looked like it would be good also but had DT set for quick release so couldn’t get full effect. The OS 25FSR showed very good performance, with 8×4 competition Top/Flight wood prop it was not lacking for speed 😀 Launched 3 more times with same performance than it got dark 🙁 Hopefully the winds will die down so I can see what happens this weekend.

Hey Scott, it sounds promising. Do you have any rpm numbers fro that engine? Just wondering about the prop choice. That peop could be hard to replace!10/08/2009 at 3:19 pm #46981
Dan, I don’t have a tach. so I don’t know what the rpm’s are. The spec. on the engine with a 9×3 prop is 19k. I’m running 35% pop, no venturi, and a hot plug I’m estimating RPM’s in the 20-21k range. I will be experimenting witn various props when I’m comfortable with the flight pattern. i.e. APC 8×4, Master Air Screw 9×3, Cox 8×4 etc. I am very pleased so far with it’s pwr. pattern.

The rear fin mod is something that I have seen done for a long time- since the seventies….I always liked rear fins as it seemed that it made the model groove nicely in power- plus they looked cool!
Good luck!!10/21/2009 at 4:07 am #46983
Yep, fins belong on fish and fuselages, not stabs.10/22/2009 at 2:44 am #46984JLorbieckiParticipant
I knew this would get Berry outta his cage!
Hey guy, what’s happenin’? Just finished repairing NATS damage- we broke two F1J models, one F1C and lost a towline in the corn. Besides that, had a GREAT time!! Sure was cool having John beat all those geared guys…10/22/2009 at 4:48 am #46985
Lotsa guys brought gear!
If I read correctly, Grant Carson won Open Mulvihill flying a twin-pusher.
Young John did good, but he wasn’t flying a twin-pusher!
Sorry ’bout this, Scott.
