G-23 goes off
I've just purchased a nice Super Tigre 3000. I know its gonna be alot of power but, not as much as some of the newer engines! Just the same it should go like hell and be reliable to. I didn't care much for the G-23 glow as it was a bear to start and wasn't all that reliable ! I think the ST3000 will be a better choice for me!
I guess I won't get as much a charge out of it being its glow and not electric! LOLOLo

Electric powered Gee-Bee "Y"
I have flown my MaxCim powered ( http://www.maxcim.com )Pacific Aeromodel Mfg. Gee Bee “Y” ( http://www.pacaeromodel.com ) and I am very pleased with the performance. It handles very nice with no strange surprises. It is a big beautiful airplane. The MaxCim equipment performed the way I have grown accustomed to their equipment to perform. It is a pleasure to not have to worry about the power aspect of a model. I have become totally addicted to electric powered 40 size and up models. I will have my fleet at the NEAT fair next week.
Here are the statistics of the Gee Bee “Y”:
MegaMax 3.7-3Y Brushless motor – direct drive (wow what power)
MaxCim Max u35-36 controller
MaxCim wiring harness
Weight ready to fly 19 lbs. 2 oz.
20x11 APC e-prop
4 MEX solderless power tubes with a total of 36 Panasonic 3000mah cells
( http://www.modelelectronicscorp.com )
Flying time typical 10 minutes

gee bee test flights 5 all very good
My Pacific Aeromodel GeeBee is powered with a first place 2.4 with CB auto advance. The plane flies extremely well, moderately aerobatic takes off and lands like a trainer. No bad traits. Hard to stall. I did use 4-40 pushrods and Sullivan links all over. Plane is a pleasure to fly and looks great in the air. All five test flights perfect. This particular airplane can be purchased.

Hey guys, sorry to come into the thread so late. Two comments. First, a 2.4 seems like a lot of engine for that model, and I'll bet it lands like a rocket. Second, I've seen some varying opinions about the colors of the Y, Red & White or Cream & White. Remember, everything was black & white in photos back then. I think that some folks have seen the GeeBee model D in Cream and Blue and from profile angle it does look like a model Y, and I think that is why it has been said that it is Cream and Red. I'm pretty sure that both Y's were in Red & White. Also, these wheel pants on these Golden Age racers always seem to be the hardest part to keep in good condition, because the wheels either have to be able to ride up and down inside them and not hit them (darn near impossible), or the wheel pants are attached to the gear rather than the wing, and they can be rolled under when the wheels bend backwards and be torn apart that way. Doesn't seem to matter what company, it's hard to find the best way. I'm tempted to check out the Robo-Struts somebody above talked about, I think that's what they're called.

Jerry L., I think the G-38 is too much engine for that size bird. I think Rev has a good match there, and I think that 38cc's would be too much for it, and that it would land VERY fast.
Daleroger, I flew my Spacewalker II with a Saito 1.50 and it had okay power at about 14 pounds (it weighed in a bit heavy for a S-Walker II). For the size and weight that's been indicated here, I think the Saito 1.80 might be a touch light on the power.

Wait a minute, I just realized that the weight that I was referring to as indicated here was the electric version at better than 19 pounds! Scratch my last response, Daleroger. If your bird comes in at approximately 14 to 15 pounds all-up, then the Saito 1.80 would do great. Sorry about my hasty and ill-researched response previous to this.

Hi GEE-JMBO, when you say that the G-38 is to-much for the geebee-y' are you talking of weight or the power. the g-38 with muffler is lighter then most 2.4 with ING and battries

As stated before, first place 2.4 with ignition and batteries weighs the same as a G23 but will turn a 20 x 6 at more than 7000 rpm. Balance CG came out properly - no problem with wheel pants as the rear support strut takes the load of the wheel trying to move backwards. Airplane weighs 15 lbs. Built three = sold two = one left. Very very nice airplane.

My Saito 180 turns a carbon fiber prop to 7900 rpm static. Based on crashkups experience, the 180 should be a good choice , and it's probably alot lighter than the First Place 2.4 .

Weight isn't the issue, landing speed is. A 2.4 is 39.33 cc's, more than a G-38, and most of today's brands such as Brison put out more power than a 41 or 42 cc US41 or Quadra. That means that small plane is landing, or more precisely trying to land under enough power to take it off under normal conditions. Yes, I can handle a plane that lands hot, but I'll bet you lotsa donuts that the landing gear and those expensive (50 bucks as i recall) wheelpants can't handle it. My GeeBee Y from NW HobbyTech is about 21 pounds, quite a lot bigger than this model, and it has a US41 in it, and I had to prop it down to a 20 X 6 to get a reasonable landing speed. That's essentially the same engine you're talking about putting on a MUCH smaller model. This looks like a pretty good model, why make flying it no fun by making it too fast? The 33 cc engine should be plenty to make this particular model do scale & plenty more, and landings should be manageable as well. Guys here are indicating that they've flown these with a Saito 180, the prototype was flown with that as well, and that is about the same amount of engine as a gas G-23. So, if a G-23 will work (23cc's), and a 33cc Ryobi is plenty-plus, why in the world would you want to put something like a 2.4 (39.33cc's) on it? That's like putting a .61 on a .35-sized plane. Too fast, not to mention the excessive strain on the airframe. Just my two cents worth here, guys, not intending to pick on anybody, but rather because I hope that my observations might be of some help in making your experiences with this model a good one.

I am running a ST-3000 on my NWHT Gee Bee Y (mine weighs about 18.5 lbs) and it is PLENTY. I fly off thick grass with no problem. The slower you can land it the more your wheelpants will thank you.

Gee Bee Y
I have posted on here about this plane,but have rec'd some very positive comments on the flight on my Gee Bee Y....most people say that it flies in a scale like manner....can do loops,rolls and even a decent knife edge..lands are with a little power..seems as if you run out of air speed,the nose drops...Believe I know...am working on my second set of wheel pants...BTW,am flying mine with a G-23 and swinging an APC 17-6 prop....no problems with this set up..really grooves now..am a happy camper.............

Jimbo, don't you think a higher weight makes for a higher landing speed ?? You seem to say that the prop will slow it down, but the wing loading doesn't matter. With all due respect, I disagree.
Sure, large props act as a brake, but that only goes so far.
