Park Zone Spitfire Mk IX with PZ 480 (960Kv) & MAS 3-Blade Results

Hi guys,

I have flown my Spitfire for over 10 flights over a span of one solid week and yes, including week days visiting my RC Club right before work and including this past weekend where the model exhibited very good (meeting my goals) with good scale flight characteristics (it is not a speed demon, however it is no slouch either) and most importantly the landings are a thing to see....no nose overs and the approaches are very slow and manageable with greasing the landings every time.

I am not saying that I was not able to land this model in STOCK form before and as a matter of fact I did and have Video should you all like to see again just that the lighter wing loading and most especially the heavy weight up front (Stock Spinner hardware with large Metal Nut for securing Stock thick plastic spinner) is not longer an issue.

I must have put 5 flights just on Sunday morning and in steady wind of 8 - 10 MPH so, I did not see the model exhibit too of a floaty manner and loops were just fantastic. I am sure that if I change out the Master Airscrew 3-blade back to the Stock Park Zone 2-Blade (9.5 X 7.5) it will provide additional RPMs at the Motor shaft and result in more airspeed but, at present, I really love the looks of the 3-blade.

I do not have any new Video to share but, in comparison with the GWS 4-Blade propeller as shown here:

The model has considerable additional Airspeed using the MAS 3-Blade (10 X 7 X 3).

All in all, I am very pleased of my modifications to my model and just wanted to share my findings with all of you.

A few pictures of the latest look of my Spitfire: (Durbro 3-Blade Spinner, MAS 3-Blade Prop, & Park Zone 480-960Kv)

Yeah... There are plenty other suppliers. I'll avoid BH from now on! Sorry plane got sold quickly. Finally got an apology from BH and my F22 parts are despatched - only 3 weeks late! They don't publish their number but it is 626-373-2288 :-D

Just curious about the size and manufacturer of the 4 blade and 3 blade spinner you were using? Also were they E-Flite retracts that were causing you problems?

Regards,
Alan
