Default CMP Extra 300 ARF I need some advice...

Will a Supertigre 3000 pull this sucker around? Has anyone built one? I tried an extra 300 on the Great planes flight simulator. I love the way it flew. It was a lot of fun and i wanted a big plane and found this discontinued ARF on craiglist. I have the supertigre on the shelf. I also have a 3250 but i thini that's too big and it is mounted in a walt moucha Marquart Charger. Anyway, any advice?

Well there's a reason it's been discontinued; the thing weighs as much as a boat anchor so the wing loading is really high, it won't 3D, it will do a tip stall at the drop of a hat, do you need more reason to bypass this bargain?

If it is the all fiberglass one (or maybe it was just the fuse...I dont recall).....everything Zeeb said is on the spot......it was a real piece of s***........It was way overweight.....very tail heavy......and would snap at the slightest provacation......as my Ex's did while bringing it in for a landing......I would personally run very far away from any airframe with "CMP" in the header......

In that size range, I'd buy one of the new AJ Lasers. They are really remarkable performers able to 3D or precision well enough you could fly entry level Pattern or IMAC. The CS out of the company is outstanding as well and they can offer advice about setups for particular models.

I have several Extra's and the Laser fly's better than any of the ones I've had or have now.

If you're dead set on a 300 Extra, go checkout Extreme Flight.

Well the ARF CMP is only $150. I was going to use it as a stepping done once i get comfortable with my 60 -60 again. I'm flying the great planes realflight extra 300 on the simulator and it's a blast. What a fun plane! that is what sold me on the extra 300. The real flight version floats in very softly.

Well trust me.... that CMP WILL NOT fly like your sim, in fact it's a real handful to keep it from snapping.

The issue you'll have with most of the newer models that size is that they'll be electric powered, some provide the option to go with a nitro motor as I believe the AJ Laser does, I know you can do either on the bigger models. Here's a 48" Extra 300 that will most likely fly even better than your sim but I don't think it can go nitro and it's only $180.00.

Do what you want, you asked for help and you got it. If you choose to ignore that advice, so be it.

Ng,
You will find that any of the mid wing aerobatic airframes from the more reputable companies in the 30cc-50cc size will fly with similar characteristics.....so specifically limiting your choices to a particular style based on the way the simulator flys isn't doing you any justice. A Extra 300 is going to fly almost the same way as a Extra 260....Edge 540.....Slick 540....etc...etc.

If cost is the determining factor.....look into used airframes. While its no longer produced.....one of my favorites in this size was the Great Planes Patty Wagstaff Extra 300.....which I think your ST-3000 would probably fly in a scale fashion. They can be found for around the $200 range if you look hard enough. Mine had a DA-50 and it was one of my favorite airplanes till I dumped it in our pond at the time.

The $140 for the CMP is not a bargain....most if not all of any hardware included will probably need to be replaced. You will be lucky if the airframe is even built right.....like matching incidences....glue in all the right places......I've even heard of them putting two of the same side stab halves in the kit....so be prepared to do a bunch of rework. For an experienced modeller...this would be alot.....for a novice.....it's really alot.

Most of the responses in here are from folks who have experienced these airframes....and like you...we were trying to save a little money. We found out all too soon that there was no money to be saved.....Good luck in whatever you choose.

Are we talking about the same plane? This is a built up lite ply fuse. It is not a fiberglass version.

I have seen the weight around 14lbs. Is that heavy for this size plane? If I look elsewhere what should the weight be?

NG,
I understand now that this is the built up version vs the FG version as I originally thought. It helps if you post a link to the particular model you are referring to. 14 pounds for a 73" aerobatic airframe is a little fat.....but not detrimental by any means.

BUT......everything else said in this thread regarding CMP in general is spot on. You need to really ask....why is this 73" airframe selling for only $140 when everybody elses airplanes sell for 2-3 times more? There is a reason for that and unfortunately many find out when its too late.

There is a lot of experience in this thread. We too were lured by the incredible prices only to find out that you get what you pay for....and sometimes...not even that.

In the end, you're going to do what you want to. When I was new to this....I was the same way......I couldnt be talked out of something I had my mind set on no matter what. I have learned through experience and a small fortune... which manufacturers and products to trust. You dont have to sell the farm to be able to put together a fine airframe.....but dont expect a "garage sale" priced airframe live up to your expectations either.

I'm not exactly new to the hobby. I took a hiatus for about 14 years. I was heavily into it in the late 90's but kids etc got in the way. Anyway, I have built my share. My biggest which was actually a rebuild was a Marquart charger biplane with a super tigre 3250. It flew very well. I was never good enoughh to fly it by myself. I always had someone land and take off. I have flown the Ace 4-60 and trainers and i will be starting with those again. I like the bigger planes. I can see them better! Anyway, if it is too heavy at that weight and you don't think I should by it i will shy away. I like the way the Great planes flight simulator extra 300 and yak fly. I want something that flyes like them. Is there anything that I could hand a ST 3000 on with a 72 inch wingspan around $300? Extra yak or equivalent flyers?

Wow that thing is bad ass! Did you look at the hardware it comes with? It looks like you don't need to upgrade anything! Have you built one?

One more observation/suggestion......if you've been out of the hobby that long.....have you seen the price of glow fuel lately? With that ST 3000.....you will be lucky to get 4-5 flights out of a gallon of fuel....
If I were in your shoes......I would sell that ST 3000 and use the funds to get a decent 30-35cc Gas engine.....like a DLE 30-35. Gas is so much cheaper....you'll save the cost of the engine in the first year easily if you fly alot....and that is the goal...isnt it? Gas engines are easier to set up and run....dont require any external starting accessories....and you dont get a ton of residue on your airplane.....just take your plane...a gallon of gas....and your transmitter to the field and fly!

I would have to defer to someone else but I haven't heard anything negative......many of these airframes are built by the same company and just marketed by different dealers....so it could very well be the same plane. The hardware package looks good!

It does perhaps not as good as the one you showed me but that plane has been discontinued. I just got an email saying no more until the new model

Well if I was going after an Aerobeez, I'd be going after this one;

http://aerobeez.com/70-24-SLICK-PRO-...CK-YELLOW.html

One of the guys at the field has one and it's just an exceptional flyer and really easy to see. I didn't put it together but from what I've seen the hardware looks good.

May I suggest that you quit looking on eBay and find a reputable dealer who can provide support after the sale?

I had one about 10 years ago.. from what I remember I didn't change out much hardware or had to modify it that much. Definitely not a 3D machine but I had a lot of fun with it. Snaps, rolls, spins, inverted flight.. not a bad plane for the price IMHO... I flew it with an OS 160fx and had a ton of fun with it.. I saw one come up on RC G the other day and thought about picking it up for nostalgic purposes.. LOL.. here is a video I made back in 2005 of me flying it. That being said, these planes do require some previous RC experience to assembly correctly. If I remember right there is not a lot to the instructions.
