So I got curious and decided to weigh my Twister. It weighs 40 ounces without fuel in the tank. Is this within a good weight? Thanks, Tim

Bueno, Tim.
My Banshee is a bit smaller than the Twister and it is 38oz.
Your Twister is fine weight, especially for the first build. /Fly the stew out of that thing!!

My Fancherized Twister weighs a quite-excessive 54 ounces, and puts be above the absolute bottom in Expert around here.  You should be fine at 40 ounces.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Thanks Dane. Here it is! I have to install a clunk tank, thinking about converting it to uniflo, and it is finished!
Merry Christmas, Tim

Hi Tim,
You have done a great job on this Twister!  I don't know how many Twisters and Banshee's I've built over the years, but at least a dozen of each and many more fixing crash damage at Sig.  Many times I've helped repair the models at my work bench at Sig with help from some of the same Guy's you chatting with, Dan, Doc, and many more.  Heck one night I helped build a complete new model even helped the guy get it covered just so he could fly it in the next round.  I guess it was all part of having fun at a great contest at Sig with all the people and friends.

SN is a great place to get help and learn from experienced people so never hesitate to ask for help and advise.

Later,
Mikey

   Hi Tim;
    We all have been where you are at. No one comes into this world with the ability to build 20 point models and fly 600 point pattern right off the bat! And most of us have been through the wars and learning curves without the benefit of the internet! But the journey was a fun and educational one that I would not change at all. I made the journey from beginner to the expert level over a period of about 17 years. I was still learning the full pattern when I attended my first SIG contest as a beginner. I was out of work at the time, and some friends helped me with the costs of the trip, but still I figured it would be the only time I could attend. Well, that first contest was in 1987, and I never missed a year up until the last one in 2012! Met many great people, made many fast friends, had so much fun I just cant tell you! Mikey Pratt was one of the reasons for that along with his and I hope my good friend, the late Mike Gretz, the designer of the Twister. The SIG family of employees, Hazel and Maxey Hester, and the towns people all made for an insured great time. Mikey used to announce at the pilots meeting on Saturday morning, " Anyone found NOT having a good time will be escorted from the field!" And it would have been impossible to find someone not having a good time. I need to get out the big box of photos and albums from those years and go through them. The stories would fill a large volume! And as Mikey said, a lot of the people responding to your thread were some of the usual suspects that gathered in Montezuma, Iowa on the fourth weekend in June every year! Enjoy the Twister. I have one framed up and covered with the initial coats of dope on it. It is a box stock Twister that will duplicate Mike Gretz's original, which, I understand is still around somewhere. As soon as I get a little more room in the garage, I plan to get it ready for paint and have it airborne this spring.
   Good luck and have fun,

A little more work today on the twister. I did a mock-up on my down and dirty adjustable rudder using a Dubro ez-connecter. If I want to change rudder offset I'll just loosen the set screw, move the rudder, and tighten the set screw...done.

That's pretty amazing Tim, you have a good sniffer! The only thing I could add might be all this balsa dust floating around. ;D

Just got the hardwood mount for the tail wheel installed in the fuse and rough sanded.

Hi Tim,

It's coming along! Hope to have it together with the wing covered this week. Fuselage is in primer (painting the fuse and covering the wing in ultracote).

Ok Tim, got the fuse and wing glued. The fuse is primed and sanded. will cover the wing, flaps, horizontal stab and elevators with ultracote (yellow). Will then mask off the wing and stab and paint the fuse Banner Red followed by a clear coat of spray max 2k clear. I will end up with a Twister with adj leadouts and outboard tip weight, adj rudder, and adj tank height. Did away with the wire gear and replaced that with aluminum gear. It might be hard to see in the picture but I also added a cheek cowl made from 1/2" very light balsa.

Tim, Brodak has aluminum gear for profile planes. The gear I used came off my 35 year old buster and will work great. There are a couple of gear on the Brodak site that I think will work for you. Look under: control line parts/ landing gear.
The two I think will work are BG-1776 and BG-1764. Give it a look, it should be easy to change over.

I like the CF linked to above need to get a set or two

One of my profiles have duralum gear from Sig.. none in stock right now (probably never again)  from their ultimate Bipe as a replacement part

Most of my other profiles sport RSM distribution versions

Eric at RSM has two sizes that are slightly cheaper than the CF hobby king ones

Ok, got the wing covered this morning. Still need to do the wing tips, horizontal stab, and elevators. I'll get that done today. Then on to filleting the wing/fuse joint and final prep on the fuse for paint. Getting closer Tim....

I’m just thinking but does anyone know if the mounting holes are the same for the Tower 40 and a OS 46 LA? Not really a big deal but wondering how the 46 would do on a Twister? Tim

My opinion, for what it's worth.... I like the 46LA, but I think it's a little excessive on a twister. It'll work just fine, I just don't feel it's necessary. I had a four stroke 30 on a twister. Currently I fly my twister with a magnum .28. It's more capable than I am at this point. It doesn't loose any power even with my hard corners (too hard in fact, but I'm still learning that).
If it were me, I would save the 46 for something a little bigger.  I got the imitation kit from Mike Griffin for my .46.

PS, I'm not at all saying is a bad idea. The guys who use a 46 on their twister seem to love it. Shug has videos of flying his primary force (similar size and weight to a twister) with a 46. I fly my primary force with an os 25 LA. So both can work very well.

Tim I believe the mount holes will interchange. I just measured the hole spacing between my Tower 40 and my 40 LA and they are very close. ( the difference being the Tower 40 has been drilled out for larger mounting bolts) I'm told that the 46 LA and 40 LA are the same case.

Looking good, Jim.
My Twister began life with an FP.35. Now it has an FP.40 and I can barely fit enough fuel on board for a stunt run, and it may not be enough for cold weather. I haven't flown it at colder than 65F weather.
Btw, the LA.40 is heavier than the .46.

Tim, I'd say unless you can't justify spending the money, don't pass up a good deal on an LA.25 LA.46. They're too good to pass up. You'll use it on some plane sometime.
EDIT: Oops, I had LA.25 on the brain. But the same holds true of both engines.

Thanks for the compliment on my Twister. I'm pretty proud of that build. I fly it better than any other plane. I have a Cardinal on the table now.

Your Twister is looking great! Nice Twister Rusty! Maybe the 46 is too much. I saw a good deal on a 46 and was thinking about the Twister but maybe for another plane. Tim

      It's more a matter of how well it runs than what size it is. All the likely candidates have far more than sufficient power capability, what matters is how well you can get them to run in this installation. The only issue with the larger engines is that you have to figure out how to get it to run well at 50% or less of capacity. These engines tend to like to run near full blast (since that is what they are designed to do) so getting it to run reliably at 85% is usually easier than 40%. With no pipe, you don't have full control over the power - I could make this airplane work with a PA75 and I know of people flying airplanes only slightly larger with PA65/75 or Jett 61s. It would be entirely pointless but you could certainly control the power well enough to make it work. It's much harder with only a muffler.

     For me, my Twister would end up in the mid-upper 30's, and I would use a 20/25FP or the "new" 25LA. That would require about "85%" of the capability of the engine, and put the in-flight setting at a medium 2-stroke. I know because I have seen that combination several times.

   If you use larger engines, you might have to experiment with venturi - *smaller* venturis - to adjust the power range and handle the relatively low RPM you will need to run.

My Twister flies on a 46LA.  Granted, at 54 ounces it's a pig, but the 46LA does work well.  I just kept adjusting the venturi down until it was just small enough so that the engine would not away on a 11x4.5 ThunderTiger prop at my desired lap times.  I think you could take it down much further in power than that.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.
