I am about to order the EF 58" Extra. I know it is late from prior posts but just thought I would chime in on the Saito 82, which I will put in this plane. We have had as many as 4 or 5 guys at a time with this engine in a variety of models. I have had mine in about seven (none have survived to this day), with the last in a GP Reactor. I usually flew a APC 14X4 in planes like the MOJO as did the other guys. In the Reactor I flew a Master Airscrew 14X6 because for some strange reason, the last two 14X4 APC props would not bite on the prop hub and so I could not tighten them. Tried sanding, extra washers, different nuts; did not matter.

Anyway, I then tried a MA 13X8 Scimitar at the suggestion of one of our avid 3D pilots, who actually suggested 13X6. I usually use 30% heli fuel but had a bunch of YS 20 fuel left over from a YS 110 that left going west, dragging a PA Edge with it and disappeared in the swamp. The 82 has plenty of power with the 14X6 and this fuel. I only had 7 or 8 flights with the new prop before the Reactor spun in (just because I fogot to clip the connector from the switch to the battery. When are they going to make a rx that works without the battery connected?)

This prop on the 82 spun up quicker and made pull outs and recovery easier, not that it was difficult before. I leaned it out to 9700 or so and backed off to 9200. While the Reactor will 3D, it is really better at pattern stuff and is pretty quick with it's thin airfoil. Seems like the EF Extra should be quite a bit better airplane than the Reactor but may fly at about the same speed if you want it to. The heli fuel will only make it better and more fuel efficient.

I would never have considered this prop without my friends suggestion so thought I would share this with you.

BTW, My 82 has most recently been in a Fliton Inspire, a Showtime 50 (did NOT like) and two Reactors. Any of you who have been flying the EF Extra and have also flown one of these I would enjoy hearing your comments about the two planes. I hope I can keep this plane farther from the ground until I am ready to land.

Thanks

Heritage rider - I've flown the Fliton Inspire and the Extra, both with YS-63s. They both fly light, but the Inspire definetly flies more pattern like - the control surfaces on the Extra are huge so it doesn't fly as precise, and it also tends to weather vane quite a bit on the up lines. The Extra does 3-D aerobatics very well and required only a very small amount of mixing to overcome roll and pitch coupling. The quality of covering and construction of the Extra are the best I've seen in an ARF. I'm sure you'll love it!

I'm thinking about this plane with a Saito 100 (because I've got one NIB laying around here), 3 Futaba S9001s, 2 hs225's for elevator (in the tail, partially for balance). what do y'all think?

Also, does anyone have any experience with the Fliton Freestyle line? I'm having a hard time deciding between the two...and someone with experience with both might help me choose. I had a Fliton Edge 60, and it was an awesome plane. If the extreme flight plane is better, I'd be willing to pay the $60 difference.

I don't think I subscribed .

Saito 100 is an awful lot of engine for the EF airframe...

Yeah, I know. But it's the same weight, wingspan, and wing area as the Fliton Edge. Plus, the 100 only weighs like 3.5oz more. I'm planning on putting 225s in the tail, as far back as possible, as well as a 9001 for the rudder (hopefully in the tail as well, under the empanage as was my Fliton edge). That should offset the weight. I was also thinking about a 3-blade for ground clearance.

If that sounds like too much engine for it, I might get one of the Fliton Freestyles now and save it 'till I'm ready to build.

Hey man, go for it! The EF is a great airframe. You'll just have to be very careful with that much engine. I cruise around at like 1/4-1/3 throttle with the 82. It's a freakin rocket!

The only reason I want the Saito 100 on it is because I have it around here and I don't want to buy another engine.
I'd bet that full-throttle verticals would be fun to watch!

It's weird that the EF and Fliton planes are nearly identical in size and weight, but the EF guys fly with an 82 and the Fliton guys recommend a 100.

Because the Fliton is heavier in reality.
Ive flown both Extra's and simply love this one. You may need some tail weight also with that honker on the front though.
I say go for the Extreme Flight, Even a little on the heavy side it still will fly great.

Yeah, the Fliton Extra is heavier than the EF Extra. The Edge is lighter than the Fliton Extra by about half a pound.
I'm glad you say it'll fly well. Another question I have is if it'll fit in the cowling. Do you have room between your engine and your firewall??

I guess if there's a motor box I could even cut an inch off of it and mount the cowling a little farther back. That'd help with cowling clearance and CG I guess. I'd hate to have to do that, but I guess I should find out whether I have to do it before I start complaining about having to .

Yes it has a motor box. There is 4 1/2 inches of room for you to mount in. From the back of the carb to the nearest conflict, which is the mounting bolt for the rail there is 1 1/2 inches of room . This is were the carb is going to hit the bolt on the .82. The width should not be issue.
I dont have my small cylinder instructions to look up the dimensions at the moment.

Also consider a different engine mount, mine will flex pretty good.

Oh fellas! At last I have maidened my extra!
The assembly has been plagued with gremlins including a new hs225 mg with a bad potentiometer and an engine fire with a new saito 82 (that's right engine fire). Everything is jake now, though. I only got one flight as I had to wait until sunset for the winds to die down, so not much to report. two clicks of up elevator with a forward cg and one click of aileron. One thing has me a little puzzled is about 4+ clicks of right rudder. The engine mounting was not my best effort, though, and I will go through it again probably its not aligned right from the holes I drilled. Lands at a walking pace and sits right down with no fuss whatsoever.

Saito 82 throttle response was not the greatest, but the low and high are still rich. I may switch to a vess 14X6 and see how it goes. I would rather stay away from higher nitro (right now, 15% wildcat with 18% synthetic.) Saito is on a cline regulator which seems to be working alright. There doesn't seem to be any pressure left in the tank at the end of the flight, but it doesn't have any leaks so I guess its good.

The only modification to the airframe I made was a suggestion by Michael H to block off the top of the hatch to prevent fuel from coming through into the fuse. I just put a piece of ultracote on there. Also, I put a piece of white ultracote across the bottom of the plane where the gear is to keep the lines smooth and to not have gunk go into the gear fairings. I may also close up the hole in the firewall a bit.

Nothing like a safe landing on a maiden flight with no serious issues at sunset with the fellas. So far, so good, extremeflight.

Isaac, enjoy it !! I've got 8 flights on mine, all in high winds can't wait for a calm day. My missus just got back from your part of the world. 50degrees!!!! must be all the burning Saito's lol. Glad you got all soted and in the air

Rab

Great to hear!

If I could offer up some advice? Get your needles right for a good transition , Your going to want to lean the low out 1/8th at a time till it starts stumbling then richen it back 1/8th-1/4 turn and richen the high back down 200-400rpm(you know the drill Im sure ) The 14x4w is the prop you want,(for3D) I havnt tried a vess yet but I did try the other woodies and they really disapointed.

Trust me I ABSOLUTELY LOVE THIS PLANE! I want you to love it just as much as I do Flew mine all weekend .
You may find the CG needs to go back farther then the prescribed amount also.I have moved my battery back two inches now and it gets better and better as the tank empties.
It was set right in the middle of the tube to begin with.

Im still dialing mine in and its getting better and better!

Mike,

Crash Test of the Extra ?

Hi guys, It`s ok Futaba s9650 for this model???

Thanks!

They look good.
If you can, run dual elevators. It will be worth it in both the CG and the over all performance. Unless you can find a way to tighten up the elevator joiner of course , then one would do just fine.

Thanks Michaelh,
That is my intention to make 2 servo on an elevator and try and a 2-stroke engine WEBRA P5 .55 ...
I hope to perform well with this engine because I read that are very good ...
Not really know what kind of capacity for fuel tank to put this engine to fly at least 15 minutes ...

Just fine!

30+ hrs on my tx and still holding up. 4 5245's and 225 on throttle. no problems. hatch getting beat up a little bit. second set of wheel pants. which are bolted on now. and don't bother getting any spinners from EF they are junk. went through 2. and my friend Jimmie D's blew up on maiden take-off. there's a pic of the tool he made for me to get the wing bolts off and on. works very well. his is the red one btw.

steve

badfish, sorry about the issues with the spinner....

one concern... you mentioned a throttle servo, so I'm guessing that you are using a glow setup.
The Elite spinners are designed specifically for electric applications and are fantastic for this application. Due to the light weight, they are not appropriate for glow/gas applications....

Hope this helps.

with an alum. backplate you would think it would hold up to glow applications. the plastic cone does not 'seem' liter than any other in this size. its a shame you can't use them for glow.

Mine's been holding up rather well. I knew it was electric spinner and didnt expect much.
One thing to do is epoxy where the screws go maybe using some tow in the process. I have them on both my Extra and 3DHS Sukhoi now.
Only reason I use them is to save the weight from the already nose heavy design.

hello guys !
i have maidened my extra !!!
great plane indeed !!!! i have a saito 91s on it and what a beast !!! i am going for break in and not 3Ded, but i tried some imac and at low rates this plane is fantastic !!!
hitec 5245 elev; 225mg ail; 645mg rud. apc 14-6.
i think this set up is not less powered than electric motor.
hope i can upload some photo
ciao francesco

nice bird....
