I believe most will have seen this but it's an interesting video where they race a REAL Spitfire and an MX2 Red Bull air races plane around an island course ...

The real deal sure had some power, that's for sure!

Can't wait for this little offering.

Thanks!

That Spitfire/Red Bull air race vid is fascinating.

Please keep us up to speed as the sequels are released!

Marlin,

Cool! I thought I had watched all of the the Red Bull racing shows, but I missed that one! Thanks for sharing!

Yeah, it was a neat little vid, would have liked MORE footage of the actual race, just to see the spitty in the air! Love the Red Bull Air Races, those pilots are absolutely AMAZING!

Spitfire, however, is hands down my favourite aircraft of all time, any age. Just a classic! I WILL have a large model some day as well, but for now, the Mk IIb, Mk IX and now this UM Spitty will have to keep me happy.

I'd rather be rolling over & heading for the deck @ war-emergency power for a mock dive-bombing run, or screaming across the runway for a mock strafing pass. Or shooting touch & gos. But not putting around. I have other planes for that. Just as I have other planes for unlimited vertical & 3D. Given that expecting a warbird to perform a scale loop has nothing to do with unlimited vertical or 3D, I'm not sure why you brought them up.
While you might not feel you are dissing the plane, it certainly comes across as that with as many times as you have posted the performance concern. if this ship doesn't have your preferred performance, it might not be the ship for you. Maybe one of those other planes you have is a properly powered spit. I brought up the vertical and 3D issue as I don't need any one plane to be EVERYTHING. I can buy a Spit and be happy with the lines and live with the performance and if not, kit bash it with the other mods. I thought I was going to feel the need to put an SX into my Polecat but I have been happy with it as stock after all. I do like what the SX did for my 4-Site, but I also have flown 4-Sites stock for quite a few flights

The SX is a reasonable option, not a really simple swap if you have to change the pinion and wires. you have the option of paying RCBabble to do it certainly. other than things like the Champ, Vapor and Ember, none of the planes get proper performance without a better quality battery and it seems E-Flite has recognized that and discontinued the current 120mah and 150mah cells and have a 160mah in the pipeline. but then I've been using the 160mah nanotechs from the start and they've been about a $1.50 each and perform quite well, even 2 years old flying indoors every week, 5 months of the year

Horizon is really on a roll this year!

and sometimes it's nice to just kick back and design and build what you want from the ground up and take all these issues by the horns and see what compromises you decide to make in getting to the ultimate model. it can be a time consuming issue building a new model, I know, I do it as a business. And unfortunately nobody seems to stock "spare time".

Looks sweet to me.

And survived a midair (or forced grounding?) with no damage........

It is quite fast, but he was able to slow it down nicely too.

In order to keep the stock 4-blade prop, we may want to switch to the solo pro motors.
Jd,

What kind of thrust were you getting out of the AP05 on the single cell? And to keep the stock 4 Blade I was thinking of boring out the hub to the motor shaft's thickness and then using some Lock-tite to keep it on. I do the same thing when putting a J3 prop on a mustang gear box.

Jim,

Again - I wasn't dissing. Being critical, yes - but that is not the same as dissing. I never said that I dislike the plane, or that people shouldn't buy it. Sorry if that was the impression.

Regarding the SX motor - I consider it a simple swap because all that's required is a pinon & connector change - as opposed to say, modifying/swapping the gearbox, or going brushless.

On batteries - back when the first UM Sukhoi came out, I was one of the first on RCG to recommend higher-performance batteries. I did a lot of battery load-testing back then. At first, the CSRC 130 was the king of the UM cells. Then Hyperion joined the fray & took the top spot. TP eventually jumped into the ring, along with others. We have surely come a long way in a short time with these little LiPos! So far, no one has been able to knock Hyperion off the top spot when it comes to performance & longevity, but the competition is heating up, I think. Now we have a couple UM EDFs that will no doubt challenge even the best of the small packs. I wasn't aware that HH is dumping the old 150 mAh UM cell. Hope their new 160 mAh is on-par with today's high-performance UM cells (300+ cycles @ 5c charge without fading, low internal resistance, etc.), but I'm not holding my breath on that one. Seems like they're slowly getting the hint, though. They came out with a 200 mA 25c pack for the UMX Stryker 180 & Gee Bee that clearly outperforms their previous UMX packs (although it still falls short of a Hyperion 180 or 240 mAh pack in terms of voltage-holding ability under load). And then there's the price. Given the price of Eflite's LiPos, I expect a battery that blows Hyperions, Thunder Powers, and Nanos off the map. So far, the opposite has been true. But they're getting better, which shows that they're paying attention.

Regarding building - I've been building kits since the 60s, and I've also done a few scratch-builds over the years. It's not difficult to throw something together that flies. However, getting everything to play well together is a different story! Nowadays, I find that I prefer to spend most of my time flying, rather than building. (As you noted - nobody is stocking free time!) I still have an 80" Scorpio Taurus Plus in the bones than I have to finish. Besides - today's higher-end ARFs are built straighter & truer than anything I've ever built myself! I stayed away from electrics, foamies & micros for years because they didn't meet my performance, flying quality, or flight-time requirements. The Precision Aerobatics Extra 260 is what got me into the e-powered scene. (Finally, an electric that outperforms my glow & gas-powered ships! ) The original PZ UM Sukhoi is what got me into the micro scene. (Finally, a full-house ship that could do a pattern routine in the backyard! ) I had been dreaming about that since I was a kid, building & flying FF models back in the 60s.

Flybarless helis, fly-by-wire multi-rotor craft, scale UM planes with 3-axis gyro-damping systems, fully-detailed, scale UM planes with flaps & floats. UM glider towing, FPV systems that weigh less than 5 grams, telemetry systems built into our transmitters, ARFs that are built better than most modelers can build at home, micro-turbines for park-flyer-size jets. WOW!! There has never been a better time to be in this hobby!

Back to the Spit.....

Skyjet,

Nice clip! Thanks for sharing! She does look great in flight. Finally, a UM warbird that flies well inverted - despite the u/c airfoil! AS3X really helps with that - I am amazed at how well my Gee Bee flies inverted, despite its u/c airfoil. Did you see him do any loops with the Spit? The one thing I have yet to see is a good demo of its climb performance.

I do often wonder how they get that performance on those stock 150's. Their piloting ability is quite impressive to boot!
