I'm torn between the Great Planes 40 size Extra kit and Great Planes 40 size Cap232 kit... or am I??? I'm looking for a relatively aerobatic/3D kit, not an ARF, between 40-60 size. I feel that i need to challenge myself with the experience of kit building. This is off topic to the subject, but whenever I see a cool new plane come out it's always an ARF and not a kit, but I guess the manufactures are just giving the majority what they want.

Back to the 2 planes I mentioned above, are both of these planes equally matched if they have the same engine? I want to be able to have a plane that can hover (3D) along with scale aerobatics. Do you believe that the weight and design difference between these planes has an impact on that aspect?; Airfoil, wing placement, etc.

I'll take things slowly though; I'm not in a hurry. I will most likely save up all the money I can (I wonder where I will work this summer )and purchase it when I can. By then I'll hopefully have enough for an engine too. I might be thinking too far ahead anyway, but we'll see.

Thanks for your time and input!

BTW, which engine is good for what I want to do in the planes I'm interested in?

I'm thinking you need a nice 40% carden edge, that should solve all your problems.. hey brian

I have the GP Cap and I absolutly love it. I have an OS 70 Surpass II with 13X6 prop and I get nearly unlimited vertical. It will climb forever but it will loose some speed. Most of the guys at the field were impressed when I take off and point it straight up just after takeoff. Then go into a nice hammerhead to complete the sequence. It has the potential to torque roll but the most I have gotten is 3/4 of a turn before my stupid fingers loose it. It is an easy building plane and EXCELLENT flyer. You may consider a FG Cowl from stans for it. I have the stock one but it was a pain to get completed and it has developed a few cracks. I repaired them but just go with a FG one to start. With my motor combo the only thing I changed was the battery location. It is now right next to the servos. I did tail mount the rudder servo.

Mine weighs out at 5.5 LBS WET

My avitar is of mine. Let me know if you want more pics.

Shortman:
Ya I was contemplating that*sarcastic* , but I can't fit that into anything I own.

SunDevilPilot:
Thanks for the info! BTW, 5.5 lbs with an OS 70.... geez! Did it take a lot to lighten it up?

-Brian

I didn't do anything to lighten it.

Followed the instructions to the letter. Very light plane if built with some care.

good news brian, now, get the ys 63!

Does anyone have any info on the GP 40 extra? I still not sure on what to get.... What about the GP Giles 40/60 size?

Thanks,
-Brian

I have the GP 60 extra, and if the 40 is anything like it, run out and get one!

I have the .40 size GP Extra, great little airplane...here is a good thread on it...

That Thread was great! I went through the entire thing, and I think I'm going to go with the GP 40 Extra... I want to get a good 4-stroke for it, but I don't know which one would be best... if you put a .91 4 stroke in it, is it much harder to fly than if there was a .70 4 stroke in it? What about the YS .63 4 stroke... I'm looking for the best performace

Thanks,
Briann

I think the YS .63 would be a perfect engine for the .40 size Extra. That is a strong little engine, and it's light enough so that you won't have to fool around to get the proper CG.

Would it have enough power to give it unlimited vertical? BTW, how much horsepower does a YS .63 put out anyway?


Thanks,
Brian

Not sure about the horsepower on the YS. Have seen them alot in Somethin Extra's and other .40 size planes, it should give you unlimited vertical.

While I can only attest to the power and performance of the OS 70 Surpass II performance I would assume that an OS 91 4 stroke would be perfect. Im my Cap I would not hesitate about putting a 91 in it. In fact, if I were to do it all over again I would most likely go with the 91. The weigh difference between the 70 and the 91 is almost nothing and the .70 balanced the plane out perfectly (GP CAP kit). The little .70 runs flawlessly and is an easy to opperate engine. Going to the field and playing with the motor is not my idea of a good time. Having said that, I would go with the OS 91!

Having a lot of prop will give you the performance you are looking for and the 91 will give you just that!

The Extra is a fantastic little aerobat, just don't get your hopes up for 3D because it will not happen without serious modification.

Thats why I was thinking about the Giles 202, although I hear that the Extra flys much better than the Giles. I want an airship that can 3D- Giles, but fly well- Extra.... what do you think about it? Giles or Extra?

Again, Thanks for your help!

-Brian

If you want 3D then your only choice between the two is the Giles. If you are a little more adventurous, you can check out Da King's thread in 3D/Aerobatic forum about his modifications to attempt 3D with the Extra. I wish I could have flown a Giles to compare the two, but a friend of mine built the Giles and didn't like it that much. I am curious about the Giles wing construction, from what I hear it is a foolproof technique to building a perfect wing. But anyone with some modeling experience should be able to build an Extra wing with no problems. If I were to do it over again I'd still get the Extra.

I wouldn't suggest a 91 on the 40 Extra. You would have to add so much tail weight to balance it that your wing loading would go through the roof! (makes for some pretty tough landings) Besides, I could hover my 60 GP Extra with a YS 91AC.

I have a 75 Supertigre on mine, which gives it plenty of vertical. I started with a 45, but if I wanted to do a vertical maneuver I had to build up some energy first. Something like a strong OS 50sx would work well if you can build it light. Remember, this plane isn't much smaller than the 60 size kit.

Part of the key to getting a plane that will 3D well is keeping it light. Using the .91 4 stroke just doesn't make sense, the YS .63 is the right motor for this plane with a 13x6 prop it will be perfect. The design of this plane does limit it's 3D capability, but it is still an awesome .40 size plane. What about the Cap? That will get you closer to a real 3D plane. But I still think that you would love the Extra.

I agree ... the extra has been to growing on me... I just like the lines of this model. It would be cheaper for me too to buy a YS 63 for an extra and a YS 91 for a giles. Does anyone know where I can find the horsepower that a YS 63 puts out anyway?

Thanks,
Brian

Look in the tachometer readings section, in the Engines forum...there are a couple guys that have posted RPM numbers.

If you plug those numbers into ThrustHP you will get a horsepower rating. I believe that they list a couple RPM figures on the YS website too.

I have a GP 40 size Extra. One of the nicest looking designs I have seen. Mine is the ARF. I started with an Irvine .53 in it but after a snap on take off (my fault) I sheeted the stabalizers for strength when repaiing it. I put in a Magnum .91 fs in it primarily for the extra nose weight. Wow. Ground handling is a whole new ball game. Just a click or two on the throttle and the tail is off the ground and it's on it's way. The engine is still new and I am sure after a few tanks I can get the idle down to a more reasonable rpm. Big 14X6 prop looks good on it and it is great in the air. This is one of my altime favorite planes.

I've built and flown them both, I still fly the Cap, it is the more capable of the two designs. I have an O.S. .70 in the nose also, turning a Zinger 14-5 prop, vertical is unlimited. That prop gives me 11 lbs of thrust on a 5lb plane, it's awesome. The Extra likes to fly faster than the Cap, the Cap does not need a lot of airspeed to be fully aerobatic. I had to add some weight to the nose with the .70 up front, a .91 would probably balance it out, but it wouldn't have any more vertical than what it has now, been tried and proven. There's not a real big difference in power between the two engines (O.S.). If you want to go all the way in a budget sized package I would highly recommend the Cap.

I have built the CAP, and it is an easy plane to put together. Stick the YS63FZ in and you won't be sorry. It will give 1.5 horsepower and "unlimited" everything.

My CAP is now with my friend who has stuck a 46FX with a homemade pitts muffler, and I tell you, it flies"wicked" with that as well.

The YS is going in my new Seduction Freestyle.
