Vertical is basically the same with all three engines too, as a few ounces heavier motor gives a few ounces more thrust--no noticeable difference pointed skyward.

I expected the Turnigy and the ST to be the same, but I'm a little disappointed the Power 10 wasn't faster for the money. I was hoping to tackle 90mph with some spped mods, but it doesn't even go 2 mph faster. I'm stuck around 80mph, no change from the ST motor.

I wasn't really looking for "speed" with the upgrade to the 36-36 motor. I just wanted to be able to have fun a little more and also be able to get some higher altitude capabilities.

You want high altitude capability? The gold 35-36C -- 1100 KV will allow you to climb vertically with the biggest challenge keeping the plane on course if you didn't move the battery back to keep a good CG. The black SK 35-36C 1400KV just does it faster with higher consumption rate (30 seconds less flight time). I have had both and fly now with the SK 35-36C. It's a hoot chasing the nitro guys and climbing straight vertical with them as well. I mounted mine using the Turnigy 4 poster and special washer. I like the mount because it puts the rotational mass of the motor behind the mount and the prop in front. It's just a better way to mount a spinning motor. Props used are 10x5 or 10x7 APC E. The gold motor, with lower KV, like the 11x7 APC E prop.

Welcome back Z-8.

I liked your comparison of the three motors. Took me a minute to figure out teh big red X on the Power 10....meaning it fits right on and no adaptor needed. You might could mentino that on the picture in the future.

Great write-up though.

Thanks

Ken

I basically have to agree with nothing here. I have both, ran both, and the little ST .10 wonder motor is not all you say it is. No charts and graphs, just a watts up meter a plane and a Tx. The St10 runs out of verticle pretty quick with a 10x7(considering the higher kv, it should be able to handle it better with the smaller prop). If you put on a 11x7e you'll pull to many amps and smoke the little motor. Maybe I'll try it this weekend before I pull the motor off on 1 quick try. Of course I'll have a camera on facing the rear. Then the st10 will become a nice 250w motor with a 9" prop on my MUS.

I'm sure you read my review, interesting how others with this motor all seem to see the same thing and not the results you see.

Like Capt Ron, I like the 35-36c for the power it adds to verticals, it makes it go a little faster on the level but it is a T-28 after all. Fast verticles are fun to fly and watch.

The little ST .10 is a decent motor, good for a stock replacement, keep it propped near stock, keep the amps at stated 29-30.

I thought we were done with the "imagination machine"?? I've seen and flown all but the ST. 10 motor and Z-8's "results" are rubbish.

What is the KV of your Park 480 motor? Thats what I was thinking of putting on my T-28. Is it a bit faster? I would think so. The Park 480 is rated as a 275watt motor.

Thanks,

Your pictures looked like you have a 10x10 on the ST. Don't expect to go vertical with that prop on any of these dogs.

The ST 10 definitely has the best vertical of the three motors with an 11x7, but only slightly and the difference is mostly evident above several hundred feet altitude. The lightness makes it easier to keep the nose on top of the plane until you lose sight (or the link, which happened to me today running the ST in the Pitts).

Because of its low motor thrust to weight in the T-28...

Turnigy - 8.3
Power 10 - 10.3
Super Tigre - 18.2

...along with its strange, heavy installation, the Turnigy is not well suited to an aircraft the size of the T-28. It's aircraft T:W was the lowest of the three. Mine also has a loud resonance problem around 50% throttle, same as a lot of people, unfortunately, so I really would need to add a lot more weight that isn't there now in the form of a solid metal mount. I won't be keeping it, though.

The Turnigy is also the only engine that ran unsafely with a high performance battery, so even these numbers, without the metal mount, aren't quite real.

As always, all of my findings are video-documented (critics seem to have lost all their videos showing actual installed thrust readings).

What are you all doing with the wobbly wheels on the struts? The Habu came with nice spacers to prevent the wheel from pressing against vertical wire. Just pushing the T-28 on the floor one wheel will nearly lock?

The gear and wheels are pretty bad, but not as bad as the alternatives I've tried.

solder a small washer to the wire to keep it away from the vert piece. I posted a pic some pages back. I run a little larger and thinner wheel.

100mph T-28

Wasn't looking to run the T-28 to 100mph but it happens. I was all set to make another Mustang run but had a bad landing. I throw the 4S 2200mah battery in my Power 10 Trojan and here's what Eagle Tree say's.

Note: The 103 mph is from a dive.

I am using the gold 35-36c motor with an APC 11x7E prop and a hobbywing 40a ESC and a Turnigy 3s 2200mah 30c lipo. I absolutely love it so far. I had a lot of compliments and some inquiries from some folks at my local airfield. I didn't move the battery back but it seemed to do ok staying straight up on the verticals with only a few elevator adjustments.

In case anyone was wondering I have the 40a ESC in the stock location and I put my finger on it after each flight and it was only slightly warm.

I clearly stated a 10x7e.

Hmmm, reading is easy, understanding what you read is getting out there, actually comprehending what you read is....

This motor is not what you say it is.(period) and now you are saying the gold 35-36c is poor. Many here run that motor, they might have believed what you said before, but with that statement you just lost...well I 'm sure they will tell you.

Interesting how statistics can be made to show different things....

But unless you are flying the motors without the plane, the thrust to weight ratios should be calculated using the full flying weight of the plane, not just the motor weights (which is what I assume you have done given your numbers). The motor weight difference will then be far less significant.

I'd be really interested to see the thrust to gross weight numbers if you have them. Thanks.
