6.25" from the rear of the mount to the drive hub. THere is still a 10mm prop shaft protruding ahead of the drive hub, that part goes through the prop.

I'm sorry I wasn't clear, I'm used to answering this question about airplanes, not engines.

Tom, I'm pretty sure I already have one of these engines in my Edge 540T V2 but I got mine from BCMA Engines. Looking at the pics of these though they have to be the same engine. Even the mufflers are identical. Adam does use a different EI and carb though. I prefer your carb due to the fact that it has the servo arms installed. We going to see a price war on these? His are $425.00.

Nope, no price war. I charge what I think is a fair price, some people willbuy from me because I provide good service, some people will choose to save $14 and buy from a stranger.

I will have a show special at Toledo though.

So I take it it is the same engine. Well personally, I wish you both the best of luck. I just hope this little beauty pulls this 28% Edge 540T V2 around as good as it looks. I think it's about time we had some folks out there making gas more affordable to the little guy. It's good for your business and, more importantly, it's good for the sport. More power to you buddy! Now, if we could just get a really inexpensive 333oz/in servo! LOL BTW Tom, this Edge 540t V2 is one of the most beautiful planes I've ever seen or owned. You sure know how to build them buddy! Keep up the good work!!! You get my vote every time.
The servo's are in the works as we speek. Bluebird will have a digital equal to the 5945 in the near future $37.00

Well that should be greatly welcomed!!!!! The way it is now, the electronics by themselves cost more then the engine or the plane. IMO they should all be about equal with the engine and plane having a slight edge. Big planes will never get REALLY popular until they do! People just can't afford them and that's a shame. Let's get these things in the range of the average working guy or girl that wants to experience 3D with big birds!!!!!
China and Taiwan are in the process of making our dreams come true.

You know, I understand that folks need to make a living off of these products and I have nothing whatsoever against that. After all, if they can't make a living then they will move to a comodity that will allow them to and leave us high and dry. I just feel that they need to feed the sport that is supporting them to make sure it doesn't die. For that reason I give great support to all of the young entrepreneurs that try to bring us good products at affordable prices. I really believe that Tom is one of those folks. I think he has done everything to give us an outstanding product at an affordable price with many options as to how we spend our hard earned money. By the same token I think that there are a lot of people out there trying to get every dime they can and don't give a damn about the sport. I don't know about you guys, but I know who's getting my business.
I agree, I think I'll order his Sukhoi when it comes out

One correction, exhaust on the TOC-53 has the same profile as a 3w, not a DA-50. Bolt spacing is 36mm, the DA is 40mm.

Tom, I now have 3 large Yak54s, quite frankly I'm all Yaked out. I'm really interesed to hear about your Sukhoi, In an earlier post I asked about the rudder on the upcoming Sukhoi, You will remember I don't like the small size of the Sukhoi. Did you deviate from scale and increase the size of the rudder? I'm saving my 53 3MM for this plane, sounds like a nice match.

Here's a bit of info I learned today and I will add to the engine instructions.

When attaching the prop if you use a thick prop and/or spinner backplate measure how much thread is left on the bolts. The prop bolts must engage the hub at least 1/2" or you run the risk of stripping the threads.

If your prop. backplate and any washers leave to little of teh screw protruding out the back you must replace the bolts with longer ones. I have longer bolts here, they are 5mm x 45mm, or you can get them from Microfasteners.

If you strip the threads on one bolt, stop. You may be able to recover from it with longer bolts in all 6 positions.

That scale weight needs to be revised downwards a couple of tenths. You won't use the exhaust gasket, the box for the spark plug, or the baggie. Well, there might be some alternate uses for the baggie

I just sent out a revised instruction sheet by email, but apparently I don't have the email address of every purchaser. If you did not get one, email me ([email protected]) and I will forward a copy to you.

Basically I am cautioning that the screws must engage the prop hub enough but not too much. Failure to do so will result in either stripped threads or broken bolts resulting from the prop not being tight. It may br necessary to use longer bolts, they are 5mm bolts.

I advise against using 10-32 screws, the hub is aluminum and using the wrong screw can aggravate the problem of stripped threads.

Taurus, BME, DA, and 3W all use a similar multi-bolt prop hub arrangement. Don't use aluminum or stainless screws, and use screws that make it to the back of the hub and everything works just peachy. Tighten and loosen the screws in an opposing torqu sequence and props stay nice and tight. Check the bolt integrity after the first 15 minutes of flight and at the beginning of every flight session. If the bolt passes all the way through the hub and sticks out the back a little it harms nothing as long as the excess doesn't hit anything or roll over the Hall sensor. The length of the bolt will have to be determined by the length needed to make it through the prop, hub, and spinner backplate. Since all backplates and prop hubs are not created equal a small supply of various length bolts should be on hand to meet the practical need.

There's no reason on Gods' green earth to change what works very well already.
