Sig Cap 231 vs. Sig Extra 300
 

Would like to hear comments on the Sig Cap and/or Extra.. My brother has the Extra, but has yet to fly it. I've had my eye on the Cap but would enjoy hearing comments on either/both planes.... ease of building, flying characteristics, one smoother than the other..? takeoffs, landings.. etc.. Compare and contrast the heck out of 'em. Thanks for any feedback.
:D

Both the extra and the cap are killer fliers! They look great,fly great, built light and strong etc.. I own the extra and I love it! I highly recommend it. Do a search within RCU. You will find alot of info on them.

Never flown the Extra so I can't comment, but the Cap will weight about 2lbs less when done.

RE: Sig Cap 231 vs. Sig Extra 300
 

I am bumping this. I also would like to hear about these two planes. Which one would be more stable or is it all in the set-up?

RE: Sig Cap 231 vs. Sig Extra 300
 

The response is overwhelming

RE: Sig Cap 231 vs. Sig Extra 300
 

The better plane? That depends on what you will use for the motor and what flying you want to do. The Extra needs a little more power than the Cap to have the same power to weight. The Cap does better 3D type flying due to the design differences. The Extra is a very good pattern type platform. I flew the Extra with a gas motor, the BME 50 is incredible. A friend flys the Cap with a Saito 1.80, wich need expensive 30% to have incredible power. His also weigs alot less and lands better. If you put a Moki 2.10 in the Extra, I think performance will go up quite a bit but then, EXPENSIVE GLOW FUEL AND LOTS OF IT.

Thanks, trying to make a decision on my next plane. I have never flown a Cap or Extra and was just wondering which one is the easiest to handle. I have a 180 that needs a home and would love to try the sig Cap.

RE: Sig Cap 231 vs. Sig Extra 300
 

They're two very different airframes. They do not share any parts or construction methods, etc....Think of them like they are from two different mfgs.

The only thing they share is the (IMHO) flawed aileron mount method. The servos are mounted to the hatches. There's plenty of room to hard mount them to the wing standing upright, and there's no good reason to mount them the way Sig chose to....

The Cap is lighter, I flew mine on a Moki 180 at 12-1/2 pounds. It was pretty overpowered, but flew well. I even won pattern meet in sportsman class with mine when it had the original MDS148 on it. With the MDS 148, it was about 8 oz lighter and power was about equivalent to my buddies Sig Extra with the OS160. Snapped and spun like a Cap should, tracked well. I think it flew much better than the H9 73" Caps I saw flying...I'm convinced the airfoiled tail and almost 2 lbs less weight made the difference.

My flying buddy has the Extra with a OS160 at 13-1/4 pounds. The Extra is not overpowered with the 1.60 and the extra weight. Flies like an Extra, tracks very well. Early Sig Extras had firewall problems and later models have aluminum angle reinforcing the firewall attachment.

As for landing, etc.....They are both relatively high performance aerobatic aircraft and their takeoff, landing, etc...are not real different from each other. Depending on CG location either could be a handful to land or not.....

I'm gonna assume for a second that when you say 180 that you have a Saito 180?

If so, for power-to-weight, the Cap is the way to go. Start with the CG at the recommended 27%MAC in the instrcutions and you'll be fine. My Sig Cap was my first large plane and we both survived.

What have you been flying?

BTW - I sold my Sig Cap to buy the new Chip Hyde Cap-X...It is an incredible machine.

Hill202;
If you already have the 1.80, try the Cap, you will enjoy it. I also mounted my servos on top of the wing servo tray, not inside.

RE: Sig Cap 231 vs. Sig Extra 300
 

yes Saito 180.

Current planes I have and can fly;

Ultra Stick 120
H9 80" Cub
4* 60
GP Cessna

I have a P51 that is not ready.

I really want the Cap but not sure if I can handle it. The Caps I have seen fly ( not the Sig) seem to land really hot

RE: Sig Cap 231 vs. Sig Extra 300
 

You'll be fine with the Cap. It does not have to land any faster than any other high performance aerobatic plane. It's not going let you slow down and mush it in like the other planes on your list, but neither would the Sig Extra (or any other similar sized Extra/Cap/Edge/Sukhoi). Generally, the Edge designs seems to be the most forgiving for landing, slow speed, 3-d, and stall characteristics, due to the straight leading edge...

Generally you'll fly it in to the threshold with a couple of clicks of throttle in level or slightly nose down attitude, then get all the way out of the throttle and feed in elevator as it slows down and let it sink, then flair to a landing. Be sure you have a nice low idle to get it to slow down quickly after throttling down. If you get it too slow, too soon, you deifinatley risk a tip stall into the dirt. Again, that's not specific to the Sig Cap. Generally, the lighter the wing loading, better the low speed stall characteristics, and the Sig Cap is pretty lightly loaded.

thanks, good information. It is time for me to make the transistion to a high performance areobatic. I feel like i can handle it in the air. You are right, all of the planes on my list I am able to "mush" in.

RE: Sig Cap 231 vs. Sig Extra 300
 

I have the cap with a saito 180. Comes in at exactly 10 lbs. Its a perfect combination.I think you will find it fairly easy to fly and land.

RE: Sig Cap 231 vs. Sig Extra 300
 

anyone have a wing break in flight on the sig extra 300?

RE: Sig Cap 231 vs. Sig Extra 300
 

Would it be to much if you were to mount a small gas engine(Brison 2.4) in the cap. I know the extra can handle it, but can the Cap's frame handle it....any info would be appreciated. [8D]

RE: Sig Cap 231 vs. Sig Extra 300
 

I have had both the Cap 231 and the Extra, both flown with a YS 120FZ. No doubt about it the Cap is a much better all around aircraft. The Extra weighs more isn't near a responsive, the trim colors don't match the cowl/wheel pants. I am on my third Sig Cap 231......it is a love afair!

RE: Sig Cap 231 vs. Sig Extra 300
 

i had both planes as the same time 2 different animals cap is 3d king extra was smooth imac stuff both had strong rudders.

Deleted - Sorry, I posted this to the wrong thread.

RE: Sig Cap 231 vs. Sig Extra 300
 

Do like I did, buy both! The Cap (ST2500) is more responsive than the Extra (ST2000). For IMAC style flying the Extra is the way to go, is longer than the Cap also. For more agressive stuff the Cap will be better.

RE: Sig Cap 231 vs. Sig Extra 300
 

I had the Extra it was a good flying plane. Powered by Saito 180.
