Well I got my plane all done yesterday and flew it. I had to put bigger landing gear on it because I am using a 21 X 6 prop on it. The plane flew great. I took it up for a little bit and was going to land to check it over, I ended up doing a harrier all the way down the runway. The thing just floated. Then I pointed the nose up and guned it and it shot up like a rocket. I can hover a little less then half throttle. It will pull straight up when you gun it. I will hope to fly today and get video. See what the wind it like.

I believe I have some setup issues with mine. I am unable to do a flat spin and have great difficulty holding a knife edge. Prior to this morning I attributed this to my skill level, or lack of I should say. One of the club top fliers took the 150 up this moring and he could not do a flat spin either. He could hold a knife edge and even did a tight knife edge loop. However, in his words, it was very difficlult and took a serious amount of stick movement. Hovers are real difficult also with the plane wanting to fall out of a hover.

Mine has a Saito 180, JR821 servos and a JR 9303 2.4 radio. It has tons of power and torque. The CG is dead in the middle of the specified range with an empty fuel tank. Throws for low and high rate are very close to what is specified in the assembly manual.

For you pilots capable of doing 3D work with your Twist 150 what are your setups ? CG and so on.

My Cg is at 6 3/4" the battery is a 6 volt and is behind the canopy. But beware it will get squirrly if your not careful but seems to flat spin really well and i'm not much of a 3D flyer but i can get it to hover now. And it will knife edge but tends to couple to the left towards the canopy side a trim issue...Flaperons are fun for harrier until i get better actually it a type of crow function i flip the flaperon switch and the aielrons go down a little and the elvator goes up a little and i add a little more up elevator and it harriers around prettty cool looks funny but it work for me. 16X6 prop GMS 120 Hitec 645 MG Servos through out 1800Mah 6 volt battery. Airtronics RD8000 TX futaba RX. The reciever is in the stock location. Using the stock tank.

I put a 14 oz fuel tank where you are suppose to put the reciever and battery. I put the electronic in. and battery where the fuel tank was. This way when I fuel it up the cgs stay about the same.

I just order my Twist 150 yesterday and I am going to try powering it with my FX .91 does any one have any thoughts on this? This motor was on my Hangar 9 Corsair and it only need 1/4 throttle and it flew like a bat out of hell. And this plane was around the same weight and had a bigger wing. Any way someone please give me some advice on this set up also I am planning on using a 15x4W apc. My next thought is may be buying a super tiger G2300 this may be a good engine for this plane also. Thanks

The FX .91 is to small for this plane it may get off the ground maybe but it would barely fly this is a 150 Size plane i have a GMS 120 on it and did have an SPE 26CC Gas engine on it the gas engine would barley pull it around. the GMS 120 Flys it pretty Good it wont hover with the engine yet Cause i still have some kinks to work out in the tuning. i would say the best engines to use for this plane would be an FX160 or the recomended engines.

the SuperTigre G-2300 Dual BB Ringed engien would also be a good match for the plane but a 15X4 prop wouldnt do much on this plane i'm running a 16X6 prop on mine and it flys really good with it. mine is 19CC and the Tiger is 23 so there close and it would be a better combo then what i'm running most likely. but i think the best engine would be the 160 FX that what i would put on it if i had the duckets...

But if you have the 91 FX engine you can try it but at 2.8HP@15000RPM if you can get it to spin up to that speed may pull the plane through the air it is a light engine. 19.3 oz So it may do good.. the spe only put out 2 Hp at 9000rpm and it never got to that rpm max rpm was 8000. So since you have the engine give it a shot would be nice to know if it is a good engine for the plane. But if you can put a propwith more ptch for more thrust just in case and fly it around first to see how it acts. and if it goes like a scremin banshee then put the 4W pitch on it. Just my 2 Cents

I'm putting a 16X4W on mine now since i have flown it around withthe 6 pitch and see that it has enough power to do manuvers i feel confident that i will get more airflow over the surface with the 4W pitch. Just have to figure out my boggin issue in the vert and inverted flying spectrum..

Ralph L.

Thanks for your words of wisdom I will put it on and try it and get back to you later. Also did you see what I wrote about the Hangar 9 Corsair and its size and how that engine hauled that plane out of site. Also I had a 91 Fx on my Goldberg Extra 300 with a 70 in wing and it could hover that with a 16x6. Not trying to be a pain in the ***** but just want to under stand how it wont pull the 150 (61 in wing).

linkadrip

Well the OS engine's are very good engines. i put a pooper gasser on there and now a GMS 120 I'm sure an OS 91 FX engine being it is OS has more power probably then my GMS. Mainly the only reason i can see that it wouldnt pull the 150 around is the gas tank that comes with the plane is pretty big and when you fill it up it gets some weight to it.. Mine weighed 10 pounds with the gasser on it fully fueled. and now it weighs 8 pounds fully fueled. I always weigh the plane filled with fuel so i know what my take off weight is going to be.. Checking CG is emptied. mine is at 6 3/4 emptied and moves to 5 7/8 filled with fuel.

I'm sure the .91 Fx will pull the plane fine i have a 6 volt nimah battery in mine to and that adds alot of weight too. After you try your 91 if it screams the plane around let me know that will be my next engine purchase. Unless i can get my 120 running right.. not really much fun if you cant fly the plane upside down or verticle with the engine going blah pu pu puuu then dive and it goes vrooom!!! kinda a bummer to fly around like that. So i'm having issues with fuel starvation i think..[]

You'll get the plane off the ground barely with the 91. That's about it. It won't be enough to take advantage of the Twist 150's main functionality. It'll probably be like a trainer with that engine. By-the-way, the comparison between the Twist 150 and the Corsair is definitely not equivalent. The Corsair has a wing area of 752 sq inches. The Twist 150 has a wing area of 1224 sq inches and is almost a foot longer than the Corsair and 1 pound heavier. If its the only engine you have then by-all-means fly it until your piggy bank is full enough to get you the Super Tiger or an OS 1.60.

By-the-way, I have the OS FX-1.60 on mine and I would not classify it as over-powered. Even with the OS FX-1.60 (about 40oz of weight with muffler) I still had to add weight to the tail to balance. I can only emagine what you'll have to add.

linkadrip

Kinda thought that may be the case.. But everyone told me that the 26CC gas engine wasnt going to be enough power did i listen no, i had to find out the hard way and thats the way it goes. i will be intrested in hearing how that .91 does on the plane. My GMS 120 is running on 15 % nitro and hauls the plane around pretty good but it's a sport flyer it wont 3D with the 120 on it. Guess thats why the manufacture states put a saito 180 on the plane and those that do that you never hear about cause there planes fly like they should. but it still isnt even close to the 40 size with a .61FX and that tuned pipe i had on it. that plane was off the hook wish i still had it. But it meet it's end so now the engine will go in a P-51 mustang with its tuned pipe and it will be my screamer..

Ralph L.

Thank you guys for all the info. Like you said it is all I have at this point so I will put it on and see what happens. Hilleyja hit it on the head I will need to fill up the piggy bank to get a bigger power house. So when I get this bird in the air with the .91 I will up date you on how it went.

I just put together my Twist 150 with a Surpass 1.20 (non-pumped) this past week. I've only got a handfull of flights on her, but she flies excellent! It hovers at about 2/3 throttle and has just enough power to be fun to throw around. I'm running a 16x6 K-series prop at about 9300rpm. I should be getting a bit more flying time this next week so I'll reserve my final judgement.

My Feedback: (35)

Well, I had the chance to put a hand full of flights on my new twist today. As a sport plane, the Surpass 1.20 is great and has got plenty of power for this plane. As a 3D plane, it needs more poop, the 1.20 requires 9/10 throttle to keep her in a hover. I was amazed at how easy the big twist is to hover, even with zero pullout. Nice inverted flat spins which can be done without loosing altitude.

I've got a Thunder Tiger Pro 1.20 I'm going to stick on it and see if it's enough.

I put a couple more flights on my twist with the fox 2.4 and they went great other when I broke the prop I was doing a harrier landing and it was almost flying backwords. I was about a foot off the ground and it stalled and dropped. I could belive how slow I was going. I had about a 10mph wind. I am playing around more with cgs. I started doing rolling harriers for the first time with a plane tonight. They were a blast. I am not to happy with torque rolls with this yet but I will have to practice more and adjust cg more. With this 2.4 I have all the power in the world less then half trottle for hover and blast out of sight on full power. Lots of fun. Need to get another prop and nicer weather and try more stuff.

Great to see there are others gettign into this plane and trying differnt stuff. So the FOX 2.4 is a gas engine. how many CC's is it?? the web site were i looked at one didnt say.. very pricy engine from that site too but looks like a cool engine for the plane. post some pictures of the plane would love to see what it looks like with that engine.

aberg22

It is a 40cc and I am swinging a 21X8 prop. It balanced great not sure on all up weight. Will try to post pic soon.

andy

linkadrip

Dang that must be insane a 21X8 prop..[X(] must have had to change the landing gear to get clearance deffinetly want to see pics of that. No wonder it blast out of sight with full power. And hovers atless then half throttle. Sounds pretty awesome.. Well i'm off to replace the fuel lines in my tank try to get mine running right for this fridays outing.

kerwin50

So just how does the 150 perform with the OS 160. I have a 40 sive Twist with an OS 61 and am hoping to have the same kinda performance.
How does the 160 stack up against the ST 3250.
I had a ST 3000 years gone back and it seemed reasonable

aberg22

Yes I had to change out landing gear I might go with one size bigger also its close to grass.

linkadrip

Now that is one overpowered Twist 150 lol dang look at that monster engine looks like it would want to fall on its nose.. very cool [sm=thumbup.gif] reminds me of this pic..

all right guys i have my twist 150 finished and i opted to install a 25cc homelite conversion on it - the motor spins an apc 17x6 prop at 8500 rpms with the magneto and coil set up-it wieghs in at a little under 11 lbs or so what do ya think of how it should fly?

markaboo929

nun yet???????

linkadrip

Yes i viewed the post. Earlier, but have no real input other then my SPE 26CC gas engine i had on the plane. it weighed 10LBS. and would spin a 16X6 up to 8000RPM on the ground. But it was a dog. it flew like a B-17 bomber and that is what my friends called it for a long time. till i put the GMS 120 on it and thats a whole other story..

You say 11LBS. 17X6 prop 8500.

According to my prop selector program at 8500 rpm your 17X6 prop will be putting out 12.7 Lbs of thrust.

now lets say you get off the ground and are flying at 35MPH hypothetically.

now your thrust has dropped to 8.9 lbs let say you manage to get going faster 55mph it drops to 4.1LBS of thrust.

Now i haven't changed the rpm this is at 8500 RPM. at all speeds.

now i dropped down to 5000 rpm and your putting out..4.4LBS of thrust.

Let change props shall we..we change to an 18X6 and are running at 8500rpm and putting out 15.5 lbs of thrust a little better. and this is what i noticed with mine but it would only spin the 18X6 up to maybe 7500 on a good day.. And it flew a little better and a little faster but had no 3D capabilities.

So your plane IMO will get off the ground. better have a long runway, it will taxi and take off just like a bomber and lumber through the air like a bomber. but the only way to find out is give it a shot and i hope that engine run good cause with that weight if it dead sticks its cumin down. i dead sticked mine at 10 lbs several times and its really hard on the landing gear and props. i busted my landing clean off once and had to fix it. i have had a few dead stick with it now with the gms 120 and it weighs 8lbs actually a little under that 7. something. and it float in like a dream. i got so good at landing with my anchor attached to the front that now i can bring it in without power like it has power strange lots of experience in dead sticks i guess.

Good luck

Probably the best gas combo is the evolution engine designed for the plane or one of them monster 40 CC ones like in the previous pics.. seems this plane is really strange on engine combos for some reason it like some and other it doesnt. i seen a video of another 150 that has the SPE 26CC engine and it flys just like mine did. I think i have my GMS issues close to solved here though.

markaboo929

thank you that was kinda the answer i was looking for - i m going to try it like that and if all else fails- either i go recomended evolution gas or - poulan 42cc!!!!!!! hope it does ok for me though- i havent flown in 8 months or so and this was to get me back on the sticks then get a good 50cc engine and plane to match-maybe light flying warbird or somthing like a t-6 or t-28........thanx you did help a lot
