My next shipment of 46cc parts will finally be here on Mon. It has been a PITA latly getting them. Last time I ordered 25 and got 15. SO I will now have the parts here for all of them that are sold plus a few, so they will again be shipping this commong week.

WoooooooooooHoooooooooooo!!!!!!!!! I haven't been this excited about an engine in a long time. I, too, have always heard that they are worth the wait so I can't wait to see for myself.

I have one of these on an Extreme Flight Yak... light enough that I didn't have to put ANY weight in the tail to balance (I added some to get it tail heavy), and it will get off the ground in about 10 feet! it will hover around 1/3 throttle, and go vertical as long as you want to. You won't be dissapointed.

Hi Scott,

Thank you for emailing me the instruction for setting the timing. I knew how to do it but I could not remove the hub. It budged a little but would not come out. Do I hit it with a torch? or bake it at 300degrees like a glow engine? Thank you in advance.

Jujst hit it with a torch for a little bit. Not too hot. If the set screws are out it should come off.

Here is some info for anyone interested. I test ran a 46 today with a Vess 22A prop. It was a new engine that is shipping out. Brand new it turned that prop at 6550. It pulled a little over 22lbs. That would be a great prop for some of the heavier planes the 46 is used on. In comparison a 21x8 PT prop turned 7100 and pulled 20lbs. A Mejzlik 20x8 turned 7550 and pulled 17lbs. I think it may be best to run the 46 on a smaller prop for a gallon or so, but after that the Vess 22A is a great choice.

Wow, that's pretty impressive.

I wonder how that translates into the dynamics of actual flight, that is if it would tend to "lug" on long verticals or cause the engine to overheat, and performance during pullout from hover...

Vess seems to have done his homework. I read his writings somewhere here on RCU and he claims to have really tuned his prop airfoils specifically for the prop sizes used in model airplanes. It appears he isn't kidding!

It's pretty hard to beat Vess for all out 3D... verticle lines are a bit slower but they are constant and don't slow down at all.

Vess is a great prop, my only issue with them is they are very loud and it's pretty easy to rip them

Not quite yet

The 21x8's are the best for most planes. I have a pile of props here and I just keep trying them until I find the one that flies the plane best. It isn't cheap, but if I break a prop, I have plenty of spares

I think I will order the 74" Yak combo soon to go with my 88" Yak. Do the ignitions for the 46 need regulated on 2 cell lithium? And if the motor is backordered and it sounds like it will be do we get the plane first so we can get started building and setting it up. Thanks, Mike.

Hi Mike,

The 46 will run on a 1 cell lipo. No 2 cell, unless regulated. A 1 cell is light. 1.4oz for the 1550 mah ones I have. By far the lightest way to go.

If you order the combo, the plane ships right away from EF.

Thank You

I fly the one cell lipo that Scott sells. It's super light and the charge lasts a very long time. Plus, if you're like me and you forget to charge before going to the field, a quick 10-12 minutes and you're flying all day. Well, all day for me is 4-8 flights. Go with the lipo. Less weight, no regulator.
BTW Scott, have you tested the Troy Built props? I'm flying the 20-8 for break-in. I like it so I ordered a 21-8 to use later. Unfortunately, I don't have anything to compare them to.

I haven't tried those props. Just Xoar, PT, Mejzlik, and Vess.

Steve, I have tried the TBM props and they are fine. Xoar is perhaps a smidge better, but not enough to worry about, and I say this without the thrust numbers that Scott has given us. Those are objective and very useful, but if you try a few different props there are just some that SEEM to perform better than others with your particular airplane, engine, and flying style. I was really impressed with the PT 21x8... best I have experienced yet. The only truly horrible prop I have used is the Zinger, and even that will still fly the airplane okay though it is clearly noisy and inefficient.

Thanks for relating your personal experience with the 1-cell LiPo on ignition. Great to hear how well it works, with a very quick recharge to boot!

Thanks for sharing Bob. I agree with you on the Zingers.[:'(] I may try a PT in the near future. I just have to warm up to the idea of paying that much to pull my plane. Those that are very accomplished pilots can tell the difference and can take advantage of it. I'm just a budding IMAC newb and I dabble a little in 3D. But I will get there! Damn it![>:]

Hi Scott,

I'm prowling for my first gasser and have read most of this thread. I'm sold! But I have a couple questions:
1. My wife really wants me to have an Aviation Models 30% Extra 260 http://www.sd-model.com/subs/arfs/extra260_87.htm It's 87" w/s, w/l 29oz/sqft, weighing 16.5#s. I see on this thread there are some flying 15+# with no probs. Will the 46 be enough for this airframe - mostly sport flying, don't care to hover and pull unlimited vertical but I don't want a dog either.
2. It seems you recommend ethanol-free fuel. I live in Canada and all of our gasoline has ethanol in it. Is this going to be a problem? Any Canucks please chime in with your experiences.

Thanks
Uduman

The plane will build very light. The 46 is lighter than any 50cc engine out there. Measured thrust on a Vess 22x8 was 22#. 20lbs with a PT 21x8. I think one of those props would work well fot that plane. Now it would not be a 3D monster by any means, but it should have unlimited vertical and do all the regular tricks just fine. Build it as light as possable and who knows. With 22lbs of thrust, it should hover a 16.5lb plane just fine. May not be a rocket pullout, but still do well. I know you do not want it for 3D, but it is a good scale to measure all around flight.

I use ethanol free fuel when I can. It will not hurt it to use it. There may be a slight drop in power and the carb will need new diaphrams faster. Once every year or 2. Not a big deal. $8 will get you a kit. I just use pure gas becuse here i still can. Premium only. Regular and mid grade has ethanol in it here as well.

Smoke for standard side-dump muffler?

Guys, when I had the little problem with the Hall sensor I decided to take the opportunity to put the DA50 into the H9 Extra, and now I will put the B46 into a RCGuys Super Decathlon. It's not due to ship until Nov 30, so I am in no rush.

ANyway, I am going to add smoke to the Decathlon, so I need to find out if there is a compatible smoke muffler or if I will have to modify the muffler myself.

Any thoughts on this?

Just install a tap in the muffler. In the rear near the bottom of the engine. Top inverted. That is all you need to do. No special muffler is needed for a gas engine. They make enough heat. No pre heating is needed like a glow engine.

Put the tap as close to the cylinder exhaust port as possible.. that's where the temps are highest to get the best burn... the best smoke... and the least slime on the plane when you're done!

Most of the smoke pump mfr's will also sell a tap kit, or you can do it yourself with some metal tubing the same size as your smoke tubing inside diameter(tubing from an old fuel tank works well, just pinch the end of the tube so that it sprays instead of just flowing from the pump). Just drill the muffler, insert the tube and braze it in place. Put a little dot of solder out near the end of the metal tube to help hold the flexible tubing on to the metal tube.

Anyone have the 46 on a Giant U-Can-Do? My son's Goldberg 330 had a radio problem this past weekend. Thankfully there was a RC friend that saw it go in a mile away, and came to the field to point out the crash site. So we have the engine, and no aparent damage. Found the antena balled up in the fuse. I know a couple of other planes that bit the dust for the same reason, trying use the provided tubes mounted in the plane. Never again.
