RE: Great Planes 1/4 scale Gene Soucy Extra 300S
OOPS.. didnt mean to respond to an individual
As I and other have mentioned, try the TopFlite Power Point and Zinger standard 18x6-10 props.. I guantee you will be pleased.. I fly a 78" Kangke Texas Hurricane on the OS160 with V30 Perry pump and this prop does it ALL. Full throttle levell flight is quite fast, as you would expect if you were flying a 10" pitch prop, YET it will hover(no accurate weight, but I'd bet long green, its a 14+ pound plane) like a 6" pitch wide blade APC . The dual or progressive pitch on these props truely gives you the best of both worlds. Ive compared, on both a GP Giles and the Hurricane, APCs, Zinger Pros(crappy), Master Airscrew Classics(truely poorer perf than a wet dog turd for a prop) and single pitch Top Flites and Zingers... the two dual pitch props KICKS all their asses big time. DONT wait just DO IT.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Here are some pics, next time I'll get some close-ups. I like to wait on decals and wheels pants untill I get it dialed in and it looks so good we may leave the decals off. Also I don't like the stock WM pilot (looks like Freddy Mercury from Queen) so that can wait as well. The last one is the proud owner Jim, I have a lot less hair.

I have an 18X8 APC and the os 1.60 turns it just fine. Here's a simply fix for the back pressure problem with the os 1.60 and the pitts muffler I learned for a buddy of mine. Just take the plastic cover from a Zap CA bottle. Its a perfect fit for the exhaust of the Bisson muffler. Drill a 1/16 hole in the top of the cap. Put it on the muffler about an inch or so and tighen with the appropriate size hose clamp. Works like a charm and the cap doesn't get hot because it it right in the air stream and far enough away from the engine.

Since the 1.60FX is the only engine I would use the Bisson muffler on and since I know it will never run properly without a stack sealed I felt it best to permamently crimp it closed. If you think about it the size of the one remaining exhaust tube is the same size as the stock 1.60FX muffler

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Got two more flights on my buddies yesterday. We crimped the muffler like you suggested and it worked like a charm. That OS1.60 starts on one flip almost every time. 1/4 throttle and turn it over 4 or 5 times apply glow starter hand flip and bam, it starts!
Didn't do to much with it yet as I'm trying to just get him comfortable enough to land it himself. Slow flight is very stable and it is similar to my Patty Wagstaff except that it does not bounce on landing at all. Rolls are very axial and next I have to check lateral balance as it seems to want to go to the side in loops.
Next time out I'll try some more aerobatics since that is what it is designed for.

For you guys having problems with not enough backpressure you may want to try one of the regulators that iron bay models has out. THere are 2 guys at our field that use them and they say they work great

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
how about a pic and some info on the g26 install. did you convert it to elctronic ignition? I maybe ordering this plane next week and may get the o.s.1.60 with it, but wood like to go gas and still keep the plane as light as possible.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Hulley,
IMO this one is just under the threshold for gas. From what I have learned in the last 6 months (my extent of gas experiance) is that for this type of plane you need to be in the new breed of 50cc gassers for the power to wieght ratio to pay off. Based on that theory you would want a slightly bigger plane for gas i.e. the GP Patty Wagstaff.
If you want this plane the 1.60 makes the most sense. My reasons for that statement is a comparable 4 stroke will run around $450, after you factor in fuel costs you might as well go gas (see first paragraph).
Zenoahs are fine for Warbirds were you will probably need the nose wieght anyways but for Aerobats, light is right.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Basinbum,
thanks for the info, I think I will go with the os 160, for the money, I think its a good bargin. To step up to the Patty and a
50cc gas would cost me another $500 to $600 when all is said and done. I have to watch my money, afterall my brand new U-CAN-DO flew away last sunday
and I lost a considerable amount of money!! So I'm not in a hurry to drop $1500 or more on a complete gas package 
. will somebody please post a pic if the radio bay.

will post pictures soon, the G26 is light and gives this extra unlimited virtical and amazing 3D. The OS 1.60 is nice too, but doesnt have the features the gas engine provides. $330 for the new zenoah G26 with the pitts style muffler plus if you opt for electronic ignition.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
the G26 is a heavy gasser...I would think power to weight not good for this plane. just a hunch. the 1.60fx has better power to weight....only drawback is fuel cost and cleanup when comparing to gasser.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Some info from the manufacturers:
OSMG0661 1.60 FX w/o Muffler
Displacement: 1.60 cu in (26cc)
Bore: 1.32 in (33.6mm)
Stroke: 1.16 in (29.6mm)
Practical rpm: 1800-10,000
Output: 3.7 bhp (ps) @ 9000 rpm
Weight: 32.6 oz 925g)
Reports on RCU of 10,000 rpm with a 16x8, 7400rpm with an 18x8 are what I got.
Compared to Zenoahs claims:
Specifications:
Displacement: 25.4 cc (1.6 cu in)
Bore: 34mm
Stroke: 28mm
Prop: 16x8
RPM: 8900
Fuel: Gas/Oil Mix
Weight: 53 oz
So a pound lighter and more rpm with a similar prop. Again, for this size and style plane, go with the OS.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
sounds like the O.S. 1.60 is a no brainer! looks like I will be ordering one this week! Ahh, finally a big plane that doesnt cost an arm and a leg. Any ideas on servos? I was thinking of Hitec 5625s digitals. and definetly dual batteries, I think I lost my ucando because of battery failer[&o]

If you want to run a smaller gasser, why not an MVVS 1.6 gas. Including the carb and ignition it is 1050 grams, 0r 37.5 oz.
Performance figures from hte UK distributor...Dynathrust 16x8 @ 8500, APC 16x8 @ 9000, 17x8 @ 8300.
Here's a link to some more end-user reviews.
http://www.justengines.unseen.org/mv160p.htm
I was thinking that this would be a good intro plane for small gas and bigger planes than I've had in the past.

what % fuel do you guys run in the os 1.60? I'm also building a Heli and it would be great if I could run 30% in both (except for the cost). does this plane have a hatch like the patty? a pic of the radio bay and engine mounted would be great. thanks for all the help from everybody, I'm ordring this plane on monday and would like any useful building dos and donts with this plane.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
Hulley,
The radio compartment is acsessed from the bottom with the wing off. You need a stand for setting it up at the field. You could easily make one from PVC with some pipe insulation where the plane will rest inverted.
Save the 30% as the lower compression ratio of larger engines like the 1.60 run better on lower nitro fuel. The OS manual does state 0-15% (I think) but 5% is about right.
From reading other Great Planes threads it seem as if the CA hinges might be suspect and using another manufacturers CA hinge or upgrading to Robart Hinge Points might be warranted. If you do use the stock hinge cut the rudder hinges 1-1/4" wide as there are only three of them and you get enough material to do this.
Everything else can be stock and works just fine. It is a very easy build.

RE: Great Planes 1/4 scale Gene Soucy Extra 300S
I have the review complete. I anticipate we will launch it between monday and wednesday this week for you guys. I included ALOT of pictures on this review. More than any other review yet.
I made a few changes here or there which are discussed in detail on the review. I didn't change the rudder hinge scheme and used the supplied GP hinges. Hard test flights showed no problems. I soak ALOT of CA in my hinges. I wonder if those who ever see hinge failure in the GP threads cut the covering, drill the hole in the middle and soak each side with 6 or more drops of CA. I use about 10 drops on each side and once dry I hit them all again with another 3 or 4 each on both sides. Hardens the wood around the hinges and makes them lock in securely.
For an extra touch of security you can use some clear tape or clear monokote to seal the gap. This is generally a good idea anyway and you will pickup some extra response on the surfaces which are sealed plus the tape adds a touch of strength to the hinge.

Marc,
I also used the supplied hinges on this one and on the tail of my Patty. So far no problems on that one either. I also have suspicions about the process used to install the hinges but most failures I have read about the hinge tore apart. I have an alternate theory as to why this might happen. Sealing the gap with monocote and running the iron deep into the seam may cause the hinge to melt and become brittle.
Adding a couple of drops of CA after the first application is dry is a sign of obsessive-compulsive behavior.

great review!! I'm glad I ordered the plane this morning from tower, $359.00 with the x-mas coupon! I will be using the O.S. 1.60fx, for the money you cant beat it! what do I finish first? the heli? or the extra? decisions decisions
