IWell this is m 3rd year flying models. I learned rathe quickly on a pt-40

My second plane is my easysport 40. Its a great plane and i can handle it great. I can do basic aerodynamics (rolls,loops,spinns,etc.) I have a OS 46 FX in it
I Fly it great and land it great forthe most part.


I am now getting a little bored with it and wnt to step up to a extra 300s. I plan to put a supertigre 51 for a little added kick lol.
Would this be a god choice for a 3rd plane? Would I be able to handle it? Does it nose over a lot? Stall habits?
Thanks in advance for feedback.

It's a great kit. If you're ready for a more advanced plane, go for it! The ST-51 will be great too!

Hey Hollewud,

I used the GP 300S as a second plane, way back when they first came out. I started my fixed wing flying with a Four star 40. Anyways, you didn't mention whether you're getting the ARF or the kit. If you get the kit, there are some worthy upgrades to the plastic ABS parts at a minimal price. Go to Stan's Fiber Tech online, and you can get a nice fiberglass cowl and a set of wheel pants. FG lasts much longer and holds up better to "bumps and bashes".

Also, when I built mine, I was uneasy about the single wing mount bolt, and simply drilled and tapped for two, just for peace of mind.

This Extra, depending on how you build it, has a higher wing loading than what you're used to. Therefore, it will land a bit faster, and use more runway on rollout. Takeoff isn't really a factor if you have the power. An aerobatic airplane must have more violent stall characteristics in order to perform some aerobatics, like snaps and spins, so be prepared for a more defined break into the stall, and one wing may like to drop. That all depends on your engine thrust alignment, balance, and weight.

The landing gear plate mounting is weak, so enforce that area with larger tri-stock, or aluminum brackets.

Extra's don't normally nose over much, in my experience, since the landing gear is angled forward, putting the wheels well ahead of the CG.

Good luck with the Supertiger engine. Most of those engines are finicky and basically a PIA. Some folks have good ones, and some know very well how to get them to run ok. My vote for your Extra would be the tried and true OS 61FX. Power is no longer an issue, and you have an easy to tune, reliable engine. Remeber you will need a Pitts style muffler, Slimline has a great line.

Have fun, and good luck

Erich

well thanks for the response....
I would be getting the Arf. You mention the pitts but at tower it said you cant put pitts because theres something with the cowling that is set up for a stock muffler. About the supertigre engine.... The thing is I want a bit of power (more then a 46). So... I need a 50 - 52. A would like to buy the os sx 50 but at 160 its expensive for a 50. You suggested a 61 fx but lol I think tahts a bit to much for a 40 size.. at least for me anyways . So i think im stuck with the supertigre for the 50 option. I dont think any engine can be worse then those OS LA's man i had a LA 46 in my easy sport and it was aweful. Had to go to the FX. Those LA's are aweful.

Magnum now makes a .52 that looks good. Haven't run one yet though. The pictures of the engine make it look like it has a different carb from the other Mag engines, so the normal Mag carb fun and games might not be an issue.

great plane. i have one with a 46fx in it and it flys like a dream
flys like it is on rails. fast, aerobatic, not good for 3d though

make sure that ST-51 will be a torque monster on T/o so make sure you have 1 degree toe in on your wheels yes toe in that way you will need mild correction on t/o so they will look good and smooth

6 am coffee 6:15 am get another coffee 7 pack up head to the field 8am fly your arse off :P

Hey I just got ito power flight after 5 years off of slope soaring. I got a graupner extra 300s with a TT61 the first flight was a disaster the horizontal stab snapped off after 3 circuts (plane destroyed but GP sent me a new one)plus being a tail dragger it was squirly on take off my second atempt was bad over corrected on takeoff and laid it down no problem. So i decieded I needed more stick time got a super stunts ran 2 gallons thru it until I hit a power line,(another story) . I then built a Daspadstick and this honed my skills backup. Now I am readyfor my maidenflight on exta it should beno problem.
By the way this is my 3rd week of flying power

In mine I'm going to use a YS 63 ... hehe but I will have holes in both my pockets! I'm going to re-inforce the tail surfaces with flying wires and carbon fiber on the stab. BTW, it will be my 3rd plane also. I hear that it won't 3D that well, but if thats not your concern then go for it.

Excellent choice, and you will enjoy assembling it.

Two comments on flying:-

1/ Be very very careful you don't use too much elevator throw Even the slightest excessive throw will make it snap, especially in a loop, or when recovering from a dive, which is a heart stopping event even when you are experienced! By a small throw I mean one that looks like it's too little. Follow the instructions and never exceed the maximum throws suggested.

2/ The plane is slippery in the air, and this, coupled with the fact that you need to come in a bit faster than a trainer means, when there's no wind, it can use quite a lot of runway to stop. Actually, it's a nice landing 'plane, as long as you don't try to float it in like a trainer, as it doesn't tend to tip stall very easily.

Keep it light. Use a little more throttle than you might be used to and don't use too much elevator. Do all that, and you will be thoroughly pleased with it.

I've only been flying and building for a year and I've heard the term build it light in many many threads here on RCU. Exactly what steps must I take to build my plane light? I don't have the experience to know where to put lightning holes as to not weaken the sturcture and not much experience with glues... the damn ca tips keep getting clogged

hollewud7, best of luck to your GP Extra, if thats what you choose.

-Brian

First let me say that when building this plane, you don't need to remove anything. When I built my 60 size, I was planning on lightening it, but everything I could think of to reduce weight was already done by GP.

So basically, "Build it light" means, don't "beef-up" any areas with extra Ply, or Fiber Glass, don't get sloppy with the glue (especially epoxy), etc.
