hey all... Just picked up an EXI 450 from Xheli, sweet deal. Just wondering what others are running for servo's. I'd just ordered 6 sg90'sn which I'm sure will fit the bill. But what sort of setup do you all have. I'm planning on a 4200Kv mystery motor, 30A ESC, AR6100e, SG90's servos. Planned changes will be a cnc had from cnchelicopter and a tri-tail.

Hey cheif...little off topic, but I maidened this animal today (2 flights). My head hurts and my hands are shaking....I just got in from #2 flight. This thing eats up 300yds of field in a HURRY...LMAO.

Oh come on Vic, we're not going to punish anyone for going off topic are we? I feel like we just moved down the flight line to the next discussion. I want to hear about what we're all doing Bikes, (pedaled or powered), picture of some nice dozers, jets, ect... It shows we all have something in common

BTW Chief, I heard a great story from a Cobra pilot.... How they had all lined up in a nice line for parade, top brass present and a Chinook came in hard and turned sideways blowing them all out of wack. They were all taking shots at each other, it was great. The guys in the Chinook said that the Cobra pilots would give them hell until it came time to carry the beer to the party

Blessings!

We used to call the hooks "big windy's".That wasn't always used to describe the chinooks either

I'd be really interested in how you run the four blade head setup. Obviously no flybar system so what else is needed for this setup. I was thinking of a tri-blade from cnchelicopter.com before but didn't have the heli for it. So if I pick one up what else would I need???

George...it only flies 85mph as stock on the straight and level (LMAO). Before this, the fastest plane I ever flew went about 40mph. It takes a 300yd field like a bullet. I shake like a mexican hairless for 20 minuets after flying it....what a rush.

Just finished assembly and test hover of #2 EXI-450 (the one that's stock). Got more setup to do before first flight:

You ain't the only one interested in the setup.I didn't get a lick of paperwork with the darn thing,so I have to guess.I'll let ya know how that goes.I do know I'll be using expo to tame it down.I believe after tracking the blades,I won't need the normal amount of pitch,so I will be doing a lot of dail in with regards to both pitch and throttle curves to tame the beast.

I think there is a forum here on this flybarless heli's. I really like the idea of flying without the flybar. I think the forum is scale heli's which is where I'll be looking when I get the money for a new tri-blade head from cnchelicopter. Or maybe a quad-head and a tri-tail... that would be sweet...

Yah.. I've heard the same that its quite touchy to fly. The heads are cheap enough but not when you have no coinage coming in. Heads now run about a hun. I have a huey body on one of my K2s which I got from DarthDrk. It really does need the elevated tail mod which I think Darth has the plans for it. BTW his canopies are very nice and very inexpensive for the quality you are getting. I'm ordering another canopy from him soon enough for the EXI. I want to put the DragonFly body and go flybarless head on it.

I like the old birds and don't care at all for the canopies that come on heli's today. They all look the same and IMO are ugly. Each to their own I guess

The canopy I got from Darth was very good. It shows seams and rivets as well. Came in white PET and clear pieces for the windows and bubble chin windows as well. I have no complaints with Darths cabins.. they are excellent. AND.. Darth has way more selection for available cabins in diff sizes too.

The canopies Hightorque has maybe a bit cheaper but the selection is far lower. The REAL nice thing about Hightorque tho is his Tail riser. Darth doesn't have anything like it but thats what shopping around gets you... a little from here and a little from there... If I go Sikorsky then I'll get the tail riser from Hightorque but if I go DragonFly I won't need it. We'll see

I did some research last night. These elevated tail rotors, they're not all the same angle (say UHN1 vs H60). In addition, the H60's tail rotor is HIGHER, requiring a LONGER belt and longer upward tube). The elevated tail rotor kit by Hightorqueusa is FINE for the huey, it won't work on the H60, and I doubt it'll work on a CH53 or other like helicopter fuselage. You could make your own and you can buy different length belts if you look hard enough. The absolutely BEST design I have found is a 2 belt system with bell crank to operate tail rotor pitch. Some people use the flex rod stuff down the boom and bend upward to the tail rotor, and it's obvious that that would be lacking because it would move, and the servo would have to work harder to move it making a BIG delay in response. This is one of the "winter" projects I think. I'll try to fabricate my own elevated tail rotor assembly. The price tag won't be much dollar wise, but it's gonna take a LOT of time and engineering...plus finding parts that already exist to incorporate into the fabrication....interesting challenge. Darth still uses electric motors (fixed pitch)...."horse and buggy" design. I'm gonna take a trip to the LHS with a piece of boom....find the material to make the bend piece that I can mount pulleys in to accomplish the drive. the bell crank is a "no brainer"

I will eventually make my own elevated tail rotor system.The only hard part is finding the right size belt(determining the right size is the trick).Lets say that maybe a 500 rex belt may fit.Find out the boom length of a 500,do some math,and it may work out.Of course I'm only using that as an example.The bearings needed aren't to hard to find,and again,don't cost too much either.I think it would actually be cheaper to get the raw materials at a LHS,rather then pay s/h for a couple of very small and light parts,IMHO.On another note,Vic,I hate the strutts on my 500.There is no way in hell I can ignore the fact that they are SOOO Wrong for a 6....=another time delay.I have to get the streamlined tubeing and do it up right,or I'll never sleep again,LOL.AND,since I am hell bound for leather gonna do it,I HAVE to add the suspension that really goes along with the strutts so the darn things work like the real deal.I have several options of making this happen,and I will explore all of them.So many ideas.......so little money

It would be nice to have a HS available nearby but for me its a two hour drive, on a good day, and the HS owner is somewhat of a git. He sells trains and planes with virtually no heli parts. A few Eflite replacement parts and thats it. But a decent HS would be nce to poke around in looking for the parts to fabricate a raised tail mech. The belts aren't that hard to come by it more of having available matching belts in diff lengths I think.

Def a winter project. or I can go simple and get a DragonFly canopy and work on the undercarriage more. I'm thinking of using some springs from RC cars or trucks in order to let the heli have a bit of give when it lands. Then it will act a little more realistic rather than hitting hard and skidding a bit. A small bounce and settle down is what I'm looking for. More work... sigh!!! lol

I've decided to do the DragonFly and work on suspension instead doing another heuy or blackhawk. Something different. Man we really need a HS for this area anybody want to come and open one??
