I have a new saito 56. I like wooden props and find TopFlite seem quieter and perform better then others I have tried. What is best size for the .56 and ptich for the Rascal. I am a 'sunday flyer and do not wring it out. I seem to take home more planes that way (in one piece that is.) Also I want to get a true trun spinner for what size is best for this ARF. Thanks C150M

I've settled on a 12/6 Graupner but the zingers ant TF work well too.
I had tried a 13/6 zinger just for grins and it pulls real hard but fly's a little on the slow side good for calm days and slow work.
Been flyin mine for a full season now great combo.

Thanks, I used zingers for yrs until last year a friend introduced me to the TF and I was amazed at the quieter sound and better performance. It was on a Saito 80 in my goldberg cub.

I use a 11x7 APC prop with satio 56 on my 40 rascal.

Thanks for your feedback. I think APC are good props but boy do they cut if a finger gets close. I think for general purpose the TF wood prop works goos too. I flew zinger for years and then switched to TF and could not believe the difference a prop can make. Have a great day

My second Rascal 40 has a Saito 56 motor, and I'm trying out several different products on this model.
The first is a Bolly three blade prop, size 11.25 X 6.5.
I also have some three blade Master Airscrew props, size 11 X 7.
The spinner is from Tru-Turn, with 120 slots, and a lite backplate.
I've also mounted a Nelson intelligent glow driver in order to make starting easier, and provide a very slow idle speed.
For flight control I'm using a Futaba 6X system with flaperon, and airbrake functions.
Other modifications include: a VoltWatch on-board battery monitor, an AirAlert audible beacon, sealing of all control surface gaps, reinforcement of the main gear and tail gear hard points, reinforcement of wing surface joints, DuBro Airlite tires and rubber tailwheel, custom fabricated titanium engine mounts, Deans two piece base loaded antenna, carbon fiber and titanium pushrods, MKD clevis and horn assemblies, NMP dual axis rod ends, Replacement of stock Saito muffler with an OS muffler, replacement of all stock fasteners with stainless hex head cap screws, carbon fiber and epoxy reinforcement of wheel pants, custom pin-striping job, installation of a lovely well endowed and scantily clad scale politesse, and other minor details too numerous to mention.
If this all sounds a bit excessive, well, it's a hobby.
I hope you enjoy yours as much as I am enjoying mine.

What is the difference in the standard 2.5inch TruTurn spinner and the 120 slot. I saw that on thier site and wasn't sure what the differnce is.

The correct size spinner for the Rascal 40 is 2.5 inches.
On Tru-Turn spinners, a 120 slot refers to the shape of the opening through which the prop blade protrudes.
All props are not created equal. The size and shape of the blade at the root end varies from one style to another, and the slots in a given spinner may not accommodate the prop of your choice without alterations.
You can modify a stock slot by carving out the desired shape with a rotary tool, or you can buy a spinner with an appropriate slot to match your choice of prop.
The 120 slots on a Tru-Turn spinner will allow the use of a wider variety of prop shapes.
You should also consider the back plate on a spinner. Some designs use a countersunk opening for the prop hub on your engine, DuBro is one example. If you position the engine such that you have a 1/16" clearance between the spinner backplate and the front of the fuselage using a flush mount backplate, you will not be able to substitute a countersunk design without re-mounting the motor, or using a spacer between the crankshaft hub and the backplate.
Using a spacer is not an advisable solution to this problem, and re-positioning the motor using the stock aluminum mounting rails is also not advisable.

Thanks Monarch97 for your informative feed back. My Rascal just arrived this week and I am anxious to get started but wanted to get all the accessories prior to beginning the building. I use TF props and a 12-6 should do well for my flying style. I assume the 120 slot should work for that prop since the pitch is not aggressive and should match the opening. With the flat backplate the engine prop hub extending beyond the fuselage 1/6 - 1/8 should do fine. I like the metal spinners compared to the plastic one in the kit. Again thanks for the info.
