Default Request for a doppler speed check.

If anyone has time and the audio is good enough.

I am curious as to how fast these particular planes are.

There may be a pass at 2:32 on this vid that is usable.

Hi Tommy,

This is what I got from you videos.

Toni
1st pass 84mph
2nd pass 108mph
3rd pass 91mph
4th pass 97mph

Spitfire

1st pass 86mph
2nd pass (About 2:30) 99 mph

I'm just learning this, but my tests on this software jived with the German program when using it on my 2 strokes. This spectrum player has a much clearer readout on 4 strokes.

Blessings, Terry

I have that toni but only fly it with saito 65. A 110 on it must be pretty quick about 120 or so. the covering on mine hasnt lasted though with the nitro fuel. I am going to recover mine and put a big "little" engine in it.

Tommy, have you tried an APC 13x10 on the Toni? That has been the best prop for my 1.10's on these warbird racers using 30% heli fuel.

Blessings, Terry

I don't like to spin my engines that hard.

We have found best results with the APC 13x13 narrow and 30%.
The plane is fast enough for Silver to allow me to fly a relaxed line that allows me to tighten it up if needed from a delayed start or if I want to hold a competitor off.
Thanks BTW!

You're welcome.

I tried the 13x13N. It has good top speed but was slow out of the turns. I'm sure the higher R's are harder on my engines but I just love the way it pulls through the turns. I getting 116mph with my H9 T-34 and over 130mph on my Strega using the 13x10. That's taching about 10.5K on the ground. We have an RCPRO race tomorrow at Kingman, AZ. The T-34 will go Silver and the PM Strega in Gold. I'll let you know how they fair. The Pacini's will be there so we will all feel slow anyway.

Blessings, Terry
