80"OMP Edge 540 & Saito 220
I would like to know if anyone has done this combo before i try it.I have a saito 220 that spins a Biela 20-6 at 8000 on 30% nitro.
Also there are a few BME 44 around that i could buy and i would like to go to gas if i can get enough power and not be over wieght,it will spin a 20-8 in the mid to high 7000 range.
The BME weighs 42ozs. and the saito is 45ozs.if i remember correct.

RE: 80
Gas=overweight when you are talking 3D and under 50cc.
Use that 220 Saito you already have.
It weighs 41 oz. with the muffler. The weight you list for the BME is without the muffler.
I'll be putting my YS160 on the one I have in the bones.

RE: 80
There are a couple of 30 cc gas engines out now that seem to be good infact i purchased 2 of them a Dl 30 and a Syssa 30. I sent the Dl 30 back because it had issues with dying. Just mounted the Syssa(made in the USA) and she weighs 43 oz with muffler ignition and eveything. She swings a Vess 18 X 6 at 8600 RPM. They will also make these engines rail mount. I am buildig a EEV2 to put this engine on. The 80" OMP Edge would be a great match for this engine also.

RE: 80
I believe the syssa will out perform the OS 160. I may be wrong but if you look around the 30cc gas engines comming out now are replacing the saito 180 and the Os 160's will more grunt and more thrust. I will be able to tell you more when I mount this engine on my plane just have to cover it and finish it out maybe 2 weeks out.

RE: 80
Unless the 30cc engines have a bunch more power than the 26cc class engines then there is no way it will outperform a OS160. The 26cc class motors won't even outperform an OS120AX. I know this because I had a OS120AX, YS110, SPE26, CRRC26 and an Evolution26 on the same airplane(H9 Showtime). Both glow engines had unlimited performance and all of the gas engines had marginal 3D performance. It weighted about 8-10 lbs(depending on the engine). The 80" profiles are 10-11lbs. Maybe a 40cc gas engine but I would have serious doughts about a 30cc gasser.

RE: 80
guy's i have been going back and fourth on this gasser veres glow for a while now.i think in this size of plane you just don't have enough plane to support a gasser.i just looked and the BME44 weight 44ozs.if you go any smaller engine than this the plane will be a slow on pullout at best,
the BME is the lightest in this class.then you have the ignition & battery to add.
the saito was slow on pull out on a Chip Hyde Tunnel Vision at 13lbs.i think it will be good on the OMP Edge if it comes in a 11lbs,and the saito just drops in the engine rails on the OMP like it was made for it.

RE: 80
16X8, 18X6, 16X5W Those are the ones I remember,but I think there were a few other sizes. I was trying many different combo's on each of the engines to find the best flight performance for each engine. I really wanted to use gas on this size plane but I just couldn't find a gas motor with enough power. If you think 4cc is going to make a ton of more power then go for it. You may get the numbers on the ground but when you get it in the air where it counts I think your going to be disappointed with the 3D performance compared to a glow motor.

RE: 80
yea,i pretty much decided to go with the saito,i just thought i could hear from someone that has tried it before.i think i will have plenty of power and not be over weight, the only draw back about the 220 is that i need a 24oz. tank for 10-11 min. flight and still have time to land.

RE: 80
Thats another thing to think about i can fly on an 10 oz tank what you can on a 24oz. You see the difference in weight savings there pluss you could mount the tank on the CG.

RE: 80
16oz tank should give you 10 minutes or better. Keep in mind that you will do most of your flying at 1/2 throttle or less unless you want to rip the wings off You don't have many choices on where to mount the tank on a profile(unless you want to do major surgery), besides the thing flies like a big foamie so a little change in the CG you won't even notice

RE: 80
Compare that with $3.00 a gallon for regular gas. Just another benifit of gas, don't get me wrong I'm not aginst glow but when you get into this size engine you are getting to the point where gas becomes more of a benifit than glow.

RE: 80
just finishing up the older model 8o in. edge. [ only red, white & blue] i put a mds 218 [ i know, i know] on it, i`ve had good luck with the 148 i`ve got. it weighs in at 11lbs. 4 oz. balance was just right with the motor all the way back & the a123 2300mah near the back of the wing. i`ll get the maiden on it soon.

RE: 80
Well i got the 220 mounted,I would like to use it because i have it. BUT with the CG at 7.5 the most aft, i will need 6ozs. on the nose to balance it and that is with a 2500 five cell in the nose also.I might get away with a big ***** spinner.[&o]
Anyone else have this problem,the BME44 is looking better and better.
Also what is the most aft CG this plane can stand?

RE: 80
That will help a lot if it is still flyable at 8",i just thought i would ask what guy's are using for CG.
OMP plans say 7"-7.5 from the root, at lease the ARF plans say that.
But in the real world 8" would not be all that uncommon.
I will try it at 8" and see how close it comes to balance.

RE: 80
I have the OMP 540 arf I had to put a Evolution 40cc gas with tune pipe on it to get it to balance on the cg without useing any lead. Mine was very tail heavy for some reason. I set it up as per the manual, but a 160 2 stroke or a Satio 180 4 stroke would not balance it.

RE: 80
Kev40,what do you think of the Evo 40,i here they are a real power house.What kind of RPM's are you getting from it and on what prop. Where is your CG at, i like mine to fly hands off when inverted.
Thanks
Thanks
