They've been informed about their link issues...

Ignition interference has not been an issue. I've even been running my G23 and G26's on Ralphs EI conversion for years.

Interference on the large planks (which I also fly) are commonly linked to the long leads needed for the servos, particularly if you put your throttle servo in the nose and run a long lead to the receiver.

Soon weedeater motors will be dinosoaurs.

Well, probably not.

But once the 2300 comes out things will certainly change: likely the same or more power than a G26 and over 20 ounces lighter.

The G90 already outperforms the standard lot of gassers substantially, due in part to over a pound shaved off the weight, so it's only going to get better.

Glow engines, they may be the future dinosoaurs...

Who will be the first to try it on a Pred?

Billme, do you antecipate any problems? Would a new engine mount need to be CNCed? How about the gear ratio?

Conversion

Can you tell us what ships are allready being used with this engine? Has anyone fitted a Raptor 60 or 90? Somebody mention EVO, anyone out there converting anything else?

Bye bye Nitro...

I want to convert my Raptor right now but I will wait for the summer test results first. I hope they are good.

Heli jack, I'm going to let Warren and others)g_? do the testing...I have to test a new engine this spring (March) that is completely new..

Felipe,

I am not going to go out on a limb and guarantee anything, but the dimensions are nearly identical to the .61 case. My feelings are that this motor will fit in with minimal fuss.

The case is too small for the .90 mounts, the 2300 will be the right candidate there, and that's what I'll likely be looking to put in my Evo 90.

A gear change is not mandatory unless you are a hard-core 3D'er, in which case that will be your biggest task to undertake.

Plugs

Some years ago i used to sell the runtronic ignition system in the UK but the biggest gaff is using the NGK me 8 plugs that fit into the glow plug thread. Being so small the ceramic is very prone to cracking and geting a misfire or no spark. So unless they have modified the heads or got different plugs that will be the week link for reliability and also the cost on the little suckers was stupid........ 30 bucks a plug in the UK.

Warren; What type of spark plugs do they use? Are they making the conrod needle bearing too?

Warren,

That was not my experience at all with the First Place engine.

I did a range check on a new plane and the servos checked out without a quiver with the engine off. However with the engine on it was quite a different story. The plane actually took off on its own and I had to ditch it. I had all the surface controls but the throttle was going nuts.

The specifications in the instructions said to keep the radio gear 6” away from the ignition circuits but when I called the motor manufacture he said you better make it 12”. After the plane was designed, I didn’t have room to do that easily. I shielded the throttle servo with aluminum foil grounded to the engine and the interference went away.

If it sounds too good to be true it probably is.
A 14cc engine is going to outperform a 23cc engine on the same fuel??? These guys are wasting their talent. They should be working for Ford or GM so they can save the American auto industry.

I have said it a hundred times, gas engines should be designed like glow engines with the bearings close to the spinning prop (fan/clutch). Zenoah’s weak point is it’s crank design. I am just a little skittish about the electronic ignition especially in a heli with limited space.

You got anything to measure the frame losses that your PCM is weeding out?

What ignition did the First Place run, maybe it was something with it? I have had 3w,and CH ignitions in my planks and on a few the ignition unit was next to the RX battery and servo and only 6" away the RX and have not had problems. Like Warren stated leads can play a big part, Had a 40% Giles 300 and the long leeds in the tail would pick up the ignition every time till I put chokes on them.

As for BME putting big power into small lite engines, they have been doing it for some time now.

Hey Ace,

It does not put out similar power; less power but over 1 pound less weight: there's the key difference in performance.

I state it has the power of a strong .70. It would appear to the person standing by and watching me fly that it is more powerful than that as I have always been pretty good at collective management (from my pattern days known as Dr. Smooth) and picking my moments to throw in a little wow factor.

It definitely does not feel as heavy as a Zenoah powered ship, and that makes a HUGE difference.

The 2300 will outperform the Zenoah's power to weight ratio no doubt, so stay tuned on that front.

And if that doesn't float your boat, I'm also working on some reed valve gassers that really honk and are very smooth! Stay tuned!

Your interference problems are not the norm I am afraid...

I have fixed many installs by inexperienced gas plank flyers and have always been able to eliminate the cause of interference.

I did all my testing on standard FM modulation before I moved to PCM; no glitching. You may have different results with carbon and aluminum frames but it can still be dealt with.

Revman;

Same little buggers, I've not had a problem yet through a few gallons and have yet to look to get a spare, so I am not sure of the cost. The McDaniel cap is nice; I think the Falkon will be a better design and more supportive as well and those are due to be standard soon

Piston and conrod are both needle bearings. Tiny little buggers. I think synthetic from day one is a smart move to keep them clean and spiffy.

strong .70

So, would you rather put it on 60-70 class heli swinging 680s? or on a 90 swinging 700~720?

Also, is the 51 based on a Super Tigre as well (can't recall if they have a 51...) when will it be out? How do you think it would compare to a Hyper, for example? Just curious, since I love the 50s...

I prefer swinging 710's since you lose headspeed. It was a fine flyer with 680's, but rather than try to re-gear I put on larger blades.

The .51 is slated for March, also Supertigre based. I doubt it will be anywhere near Hyper performance. Probably more of a sport 50 with no mess and cheap fuel.

What is the difference between the G2300 and the G90 that is currently available for BME.
I would like to try this engine in an X-Spec that is currently fitted with an OS70.
Does anyone know where I find the specs and a picture of the stock muffler?

Are the muffler ports the same as the OS engines?

Expanding on Chris's question about muffler ports being the same, I suspect they are as they seem to use the same jug as the glow version.

However, I have to ask the second part of the question, what pipes can be used?? Can you use a standard glow muffler or does it require a special "gasser" muffler?

Look on Tower Hobbies to see pictures and specs.

I don't think the exhaust ports are the same as on OS. The G90 comes with a nice 360 degree rotatable exhaust. The 2300 I think will come bare. Standard mufflers are fine.
