Larry,
Since Installing the MT on my Husky I have put 43 hours on it…here’s the summary of the testing:
Cruise Conditions:
23”/2000rpm 7000’ 110 KTAS @ 7.2gph.
Hartzell in same conditions 104 KTAS.
Climb:
8000’ FT/2400 800fpm
10,000’ FT/2000 600fpm
13,000’ FT/2000 500fpm
Closed Throttle Descent (best glide)
Low pitch 1200fpm
High Pitch 700fpm (Hartzell 500fpm)

The MT Propeller:

• Is smoother than the Hartzell at all rpm’s. You can even feel the difference on taxi. It loves low rpm’s, even down to 1800.
• On my ship produced about a 6% speed increase at cruise conditions
• Produced an estimated at least 20% better rate of climb.
• Idles smoothly at 450rpm.
• If indexed for horizontal compression, is easy to hand prop.
• Has no inertia problems on starting.
• Leaked a bit of grease for the first three hours, has been squeaky dry since.
• Will hunt a bit at high power, but after a while it’s unnoticeable.
• Reacts faster than the Hartzell to power changes.
• Improved spot landing performance.
• Shortens take-off distance 50’ to 100
• Looks good, gets noticed.
• Is the best thing I’ve done for my Husky in 16 years!

This will be our fifth season of running MT props in the off airport environment on multiple Husky aircraft, and dings have not been an issue for us. The stainless leading edge does a great job of protecting the prop from any reasonable damage.

I have only flown with the new prop twice. It is awesome, lots of pull. It sure is nice to not have the RPM limits any more.

Thanks.

I am enjoying the MT. The most notable change is the climb performance. When climbing at altitude (say changing from level flight at 6000 and going to 8000), an increase in RPM on the 403 would generate more noise than performance. The MT just pulls. I’m fairly conservative about determining whether or not there has been an increase in the top end. My observation is that I’m able to maintain a given IAS with less RPM’s after this conversion. This is with similar temperatures. So, I would venture to say yes, but I would not be willing to attach a figure to it

I tested the 88 inch Mac and the two blade MT on the same day with our ‘62 C185 with the IO-520 and the MT two blade substantially out performed the 88 inch Mac in climb to 1,000, 2,000, 3,000, 4,000 and 5,000 feet. I am especially interested in the three blade MT with our 550 conversion on this plane.

Larry/John,
I wanted to let you know I got the prop hung on my Sukhoi, and it’s absolutely amazing. The additional thrust is so much better. Thanks again for your help. I’ll make sure to refer business your direction if anyone is looking for a prop.

Just wanted to let you know how the new MT propeller is doing on my Husky. I installed it on Dec. 14th right after the STC came through. I have only been able to fly it 10 hours due to the terrible weather we have been having here, but so far I would say it is the best mod I have done to my Husky. Here is a list of the really positive changes.

1. 18.5 lbs off the nose has completely changed the handling characteristics, no more running out of elevator on landing with power off and no weight in the back. The CG with the Hartzell without a lot of weight in the rear was right at the forward limit. With the MT prop it is a couple of inches aft of the forward limit right where it should be. I was a little concerned that I might run into problems with aft CG with a passenger and 50 lbs in the baggage area, but after running the numbers I would really have to work at it to get out of the rear CG limit.
2. The climb performance is remarkably better. No question this is eye watering.
3. The removal of the 2000-2250 rpm restriction is a big help during slow flight. Seems that range is where you always need the power at 60 mph with flaps.
4. . Much smoother operation. I took your advice and tried the reduced RPM (i.e. 2100 rpm and 21 in. mp) really a nice smooth power setting with 100 kts true and 7.2 gph.
5. T/O performance is improved, but is a bit hard to say how much as the Husky get airborne so quickly in the sub zero weather we have had. Warm temps at the 5500' elevation of my strip will really tell the tale. Once you break ground it is the climb that is so noticeably improved.
6. . This one really surprised me, speed control on approach is much better. I always had trouble slowing the Husky to approach speed with out pulling the power way back which I don't like to do (shock cooling). With this longer prop bringing the power back to 1900 -2000 rpm and it slows right back to flap speed. Get the flaps down pull the power back a little more and down she comes.

I really haven't found anything negative about the change to the MT prop. I would not have a Husky without it! Thanks!

Regards

Larry,
You were right, the MT is a great improvement over the metal Hartzell. I have quicker take-off, more vertical and feel much safer. Thanks again.

Hi Larry,
What an improvement! The MT is much lighter than the Hartzell, accelerates quicker, is better for take-off and gives me more control and shorter landings. Thanks!

Larry,
Just a note to tell you how well the prop is working and how performance it’s added to my 182. The take-off and climb are better, the cruise is faster and quieter and the smoothness is hard to describe…you can use me for a reference anytime.

Larry,
I love the prop! If any of your potential customers need any performance or general questions answered have them call m

Larry,
There is absolutely no comparison between the performance of my Husky before and after installing the MT. If anyone is considering changing to the MT and is undecided, I would be happy to give them a demonstration, they would be impressed!
