Home > Plane Accessories > Propeller Overview

has it's own line of propellers. These are the best quality and lowest priced props available. Very similar to the Bolly, Xoar, Menz, Vess, etc.

We offer wood and CF propellers. The advantages of wooden propellers: they are less expensive, they break more easily so an impact with the ground will not bend the engine crankshaft as easily. The disadvantage is that wood props are more flexible so they are noisier and have a little less power at full throttle. The main advantages of the CF propellers are that they look nice, are quieter, and being stronger they can take a nose over in the grass without breaking better than wood.

PT Models CF props are here. After many years of use in Europe, we are now importing them into the US. We have tested them and they are better than Mejzlik props. They are lighter, less expensive, and spool up quicker with the same pull. We still carry some Mejzlik propellers for those who prefer them. Custom drilling of your propeller is now available for an additional $12.00. After you choose the propeller you need, please add your custom drilling here. Please note that we cannot drill a CF spinner and propeller separately and have them match up! They must both be in our possession at the same time to align them properly.

We are committed to fast service, and we usually ship the next day, but Custom Cut or Drilled Props and Spinners may take UP TO 1 WEEK to have completed depending on our workload. Please take that into consideration when ordering your items.

ALSO! Please double or triple check your drill and cut order. Almost every day we are sure we are asked to do the wrong thing like to drill a 150cc size prop or spinner cone with a 50cc drill jig. Sometimes we don’t catch the mistake. Sometimes we do, but this causes a delay because we must ask you what you want, and this takes time.

 

50cc: Use a 22x8 for break in. After 50-100 flights switch to a 23x8 after break in for the ultimate in thrust for both 3D and IMAC! Or, switch to a 22x10 for Warbirds for more speed.

80cc: For the original ZDZ-80, use a 25x10 for break in. After 50-100 flights switch to a 26x10. For the Super ZDZ-80, use a 26x10 for break in, then a 26x12.

85cc: For the DA-85, use a 26x10 for break in and a 27x10 after break in.

100cc: Use a 27x10 for break in. After 50-100 flights switch to a 28x10 2 blade or 25x12 or 26x12 3-blade. Use the 2-blade for better 3D. Use the 3-blade for quieter operation and smoother acceleration.

150cc: Use a 30x10 for break in. After 50-100 flights, on heavy planes needing more power use a 30x12. For lighter planes use a 32x10. The 30x12 spools up quicker and is quieter than the 32x10. The 30" props are not available in the TBM brand at this time, so please use the PT Models 30" props if desired.  

When installing your prop, special techniques must be employed. Just tightening up the prop bolts one time won't do it! You will lose your prop on the second or third flight otherwise! When you lose your prop, you lose your spinner too!! Check out the video of a prop coming off in flight. Go to the video page.

Proper procedure for tightening prop bolts:
1) Obtain thin steel washers and place them under the heads of the socket head screws. The heads of the socket head screws without the washers will gall the aluminum thrust washer and will prevent full tightening of the socket head screws.

2) Tighten the screws a little at a time. Tightening one screw as much as possible without the others being tight will cause uneven pressure on the thrust washer hub. Tighten one screw some, then go to the screw 180 degrees from it and tighten that screw. Go around and around several times. Don't overtighten so that you crush the prop.

3) Fly the plane for 5 minutes. You can leave off the spinner cone (of course have the backplate in place).

4) Land the plane and retighten all the prop bolts. (Not too tight!)

5) Fly a standard length flight.

6) Retighten all the prop bolts

7) Fly one more time

8) Retighten all the prop bolts. If they don't move this time (they should not). Then you have two options: a) leave it alone or b) remove one screw at a time, put on some very light thread locking compound (not too strong!), and reinstall the screws one at a time. It is not necessary to use thread locking compound, but if you lost a prop before and now you are jaded, this is your extra insurance.

9) Check the bolts every once in awhile, though the prop should never loosen if you followed the above procedure.
