As to laminar flow airfoils, nobody would notice. They are used in models. Look at the airfoil on the Great planes Viper Q-500 racer. It has the high point at the 50% chord area. This keeps the air sticking to more of the airfoil to reduce drag, for racing. It does not create a poor flying characteristic, although it may not like a highly loaded warbird on take off and landing. Again, chasing scale beyond the extent of what even scale competitors do. I think you would all be better off with a plane that is user friendly, than one you will be cursing and repairing all of the time from unwanted snaps.

I have not studied the P51 much, but from what I understand, they went even further with the laminar flow foil. They ducted air from the front of the airfoil to behind the high point to get an even higher percentage of air stuck to the entire wing. This was of course done to increase the range of the aircraft, to spend more time with the bombers. Something that this ARF will not need to be concerned with!

If the type of aircraft you like isn't being currently offered, build one from plans or a kit.

p.s. Thanks for the update Dave.
You do not see such discussions in the scale forums! lol

It is pretty funny. If you don't like it, don't buy it. It you don't like Mustangs, why read a Mustang thread? Mustangs and Corsairs will always be good sellers, ARFs will always have compromises from scale, and/or quality issues. Hangar 9 appears to be doing the right thing here and fixing the problems before releasing it

Remember, you can always build what YOU want, the way you want it. I would suggest you start your own threads. I'm sure many would chime in with encouragement as you tackle a less often modeled subject

I am not going after super scale, been there done that. most of the manufactures come on here and see what is happening and to respond to there product in public. just putting it out there what others want. look at what Topflite has done with with a 190. they are very popular and it is not a mustang or a corsair.

Seems to me the manufacturers are doing a great job. Even when you get a "scale" kit (sticks you build), there are liberties that have been taken to make the product marketable to the masses. When building, you can take them as far as you want. I think a better term to use would be "realistic", not "scale" . As "scale" is the duplication of documentation, not necessarily the real thing.

It was announced this morning by Horrizon Hobby that the Evolution G62EFI project has been cancelled; and will not be brought to market; disappointing news for folks who were hoping to install the G62EFI into the new H9 P-51D 60cc Mustang

Roger

David Eichstedt quote from RCU engine thread:

I have some bad news here regarding the 62GXI. After a gut-wrenching process we have decided not to bring it to market. Detailed testing under various operating conditions showed that it would not live up to our expectations for consistency, reliability, and overall ease of operation. Dealer and consumer preorders will be cancelled. The 62GX engine itself will be released in 2015 as a great-running, traditional carbureted version, so watch for an announcement hopefully around late spring. The plus side is that cancelling this project frees up some resources so we can work on bringing a variety of other engines to market. We have lots of other exciting projects in the works!

How awesome.....design a plane around an engine and then scrap the engine. Should we get out the popcorn.

Who needs EFI anyway? Something else to go wrong. Throw a DLE 55 R in there and have fun flying. I am sure the rear exhaust would fit better anyway, at a much reduced cost.

You can still use the engine, it just won't be equipped with a fuel injector. You will need to turn the needles, however.

I live at 5200' altitude, I traveled to the AMA nationals to compete in scale this last summer. I had my DLE 55 running great here, and after arriving at the Nats, I check my engine down there and it did not miss a beat. Never touched the needles for 3 days of competition flying. EFI may sound cool and all, but it is not necessary. Probably as realized by Horizon.

What are the prop spec's for this engine, are they much improved over the G62 of the past.

If you're asking about the Evolution 62, I'm afraid you'll have to wait until we're ready to come back to the market with a carbureted version. And of course we're not going to do that until everything is properly in place :-) !

Such as a rear exhaust configuration? That would be one of the most important configuration changes to consider for a Mustang. Not sure why manufactures continue to release side exhaust engines, when the rear exhaust configuration pretty much works better in any installation.

I know I will not buy another side intake, side exhaust. The muffler is a lot if you don't want it hanging out and they break. RI,RE is the way to go for the inline warbirds.

I don't care about the engine, just give me the plane! Looking forward to it!

Well some of us wanted to experiment with a new design. I would love to play with EFI. Best thing that happened to the auto fuel delivery systems.

I can't tell you which week it's going to ship as there are still too many unknowns, but we will get it out this month.

My HH order page still says - "In Stock"

Hmmm...

I can see a CC transaction, so I think something's headed my way next week!

Looks like the price of the retracts has creeped up since last Spring. $750+ for retracts, wheels and tail wheel retract - yikes!

Cheers

Hi,

Sorry for the redundancy if this question has been asked before, but how will this plane perform on a DLE 55RA?

Don't know that anyone has actually flown on the DLE55RA yet, but what we know is "spec" prop for the DLE55RA is 22x10, the EvoG622FI (former spec engine) is 23x9 and the ZP62 is 22x10. All have similar weight profiles. My guess is the DLE55RA may actually be an easier install than ether given the rear exhaust, which is why it's on my very short list of engine options.

I'm wondering if the DLE55RA + the EME on-board starter is a fit option?

Cheers

One think is for sure, the DLE 55 is a great engine. I have 3 of them now. If it were me, it would be at the top of the list.

Quick question.......what airframes are you flying DLE 55's on. I have only used them on aerobatic airframes. They work really great on these aircraft. Thanks in advance. i have this airplane on order but haven't decided on engine. I really wanted the 62GXI.

I have them installed in a 1/4 scale Balsa USA Fokker DVII, a Great planes Ultimate Bipe 1.60, and one is going in a 1/5th scale TA 152. The TA 152 is getting finished up as we speak. I even have an original DL 50 installed in a 1/5th scale sport Mig 3. I am building a Ziroli Stuka that has one that has been installed, but I need to buy another one for this airframe when I get back to finishing it. The rear exhaust configuration alone is worth it IMO. Not to mention, you can use the stock muffler, without having to drop another $80 or so for a Pitts wrap around, that will come loose without modification.
