Extra 300S 1/4 scale which engine should I buy..?

[rdefrei2]

Hello, I'm new to the site and today I've bought a Extra 300S 1/4 scale (Great Planes ARF Kit) Engine should be .26 to .34 gas, could someone give any advise on which engine is better for this type of airplane..?? Fugi 34..?? Genoah..??

Also is there any points that I really need to be carefull with..?? I've been on the hobby for a long time but this is my 1st 3D airplane.

Also how should I set up to learn 3D flying..?? Someone told me that I need to install "gyros" is that right..??

Thanks,

Evolution 35 should do well. If you want lot of power Evolution 45.

Gassers usually have more vibration, so "pinning" the firewall is good (drilling holes through the sides into the firewall and epoxying dowels in to mechanically lock in the firewall.) Since the kit is intended for gas, all this should be in the manual. Get ready to sell off the nitro planes too! Once you see how clean and easy gas is (and cheap) - the nitro planes don't get too many flights.
You might want to get a profile 3D foamy to practice on. They are about as easy as you can get for learning 3D and don't cost too much. Sometimes they bounce too instead of break.

Good luck!

Brillelli 46 or 50GT, Evolution 45, DL or DA 50, you have lots of options for an engine, but I'd stay away from the Fuji's and Zenoah's as they are heavy(er) and not as powerful.

Gyros? No.

Return the plane for a full refund... get out while you still can....!!!

I've seen a lot of people using DA engines, but isn't the DA50 to much engine for this airplane..?? wingSpan is just 78" and the box says from engines .26 to .36.
My concern here is weight and size.
Also what's the best place to buy this engine..?? (Good price) hheh.

Thanks.

Sorry , here is the specifications:

SPECIFICATIONS
Stock Number: GPMA1305
Wingspan: 78 in (1980 mm)
Wing Area: 1157 in² (74.6 dm²)
Wing Loading: 31 oz/ft² (94.6 g/dm²)
Weight: 14-16 lb (6.35 - 7.26 kg)
Fuselage Length: 72.5 in (1840 mm)
Requires: 2-stroke 1.6-2.1 cu in (25-35 cc) or 4-stroke 2.0-3.0 cu in (33-50 cc) glow or 2.5-3.8 cu in (41-65 cc) gasoline engine, 4-7 channel radio w/6-7 servos (including 5-6 high torque control surface servos with a minimum 60 in/oz., and one standard throttle servo)

A Fuji 43 weighs 56.5 oz with the muffler. I think you'd be dissapointed in "3D" performance with that motor. A DA or DL 50 weigh about 60 oz ($665 and $390 respectfully) and have WAY more power than the Fuji. I would try a Brillelli 46GT (55 oz and $375) or the DL if you're on a budget. You can also find nice low run time DA's for less than $500.

[heydick]

I agree with the DA 50 or the DL 50. The Fuji is a nice engine for circle flying or mild aerobatics but doesn't have the power for long uplines or good punch out from a hover.

i have that plane and i dont think i would go much less than a 50. there are a lot of choices for 50 cc motors that wont set you back a bunch. also pay close attention to the servos. 60 oz is way way too low. i would look at 100 oz. hitech has some great deals on hi tourque. especialy for the rudder as it is huge.i used the crrc50 pro and the plane flat out rips!

I was checking the CRRC-PRO GF50i and it's a nice engine at a really good price. It has a $60.00 diference between the 45cc & 50cc.

Do you think it will make a big difference if I get the 45cc instead..??


I also find some other engines like the XY-50CC AND THE FTL 52 OVERBORE AND FTL 45...

Which one now..?? Are these good engines.??

Thanks

i am not saying dont get the 45 but in my pm i was a little more open. i have 2 crrc 50s and a 26 best investment so far that i have made. i have a patty wagstaff that the other 50 is going into. do some google hunting on those others. you may not get a good feeling after reading what i had read. you cannot go wrong going larger motor. only issue is ground clearance. i am running the 20x8 on the 50 and it is a barnstormer. i am not a 3d guy. i need speed.i like unlimited vertical for massive hammerheads and fast imac style flying. nothing like a 400ft hammerhead into a down wind leg to break the prop tips free. with the stock landing gear a 22x8 or 10 will give you a skant 2 inches to play with. i ordered taller gear to over come this. whats nice about that plane is its built like a brick **** house. be very careful not to over set your rates as the elevator needs minimal defection. its a handful to fly if you over do the rates. i moved the fuel tank over the wing tube as well the battery is right on the rear most former under the turtle deck. the ignition battery is all the way in the tail where the access hole is for the servos.if you want to use the pitts style muffler you need to move the motor further forward to clear the bottom half of the motor box. i didnt want to bother as the stock mufflrer works fine (a little loud tho).there is plenty of room with the cowl to move it forward. a few 1 inch wooden dowls will make nice standoffs. another issue you may encounter is getting long bolts to mount the motor as allen cap heads are the only thing that will fit. i found them on line and got them in a few days as no local place will have anything that will work so plan ahead.
