Evan:

Am very impressed and assume that's mph, not kph. How about a pic of the bird??

russm

ya, what with?

evan-RCU

yes MPH and no I didn't tape it to my car and go 230....

This was over the whole flight so it was not a true 230 level...

Electric... I know...

All that really matters is having fun and keeping those adrenaline glands open. The How Fast is a fun little add on, isn't it?.

evan-RCU

It's great, I didn't think the plane was that fast even though I had a faster motor on this plane. I think that the red, white, and blue scheme makes it visually slower than the usual all white with red tips scheme...

Now, with my limited knowledge of electricity....if the load remains constant and the voltage at the power source goes down, the load will try to compensate for the lack of voltage by drawing more current, which can lead to too much heat. Are there any built in safe guards, or do you have to just keep your eyes and ears peeled?

Voltage goes down, propeller speed goes down and brings load with it. Pulls less amps. Hence less cells on the same motor always pulls less current.

That makes sense, the load isn't fixed.
What's the next stage for this plane? At this speed I would guess that each extra MPH could cost $100 each?
I don't see how the airframe could be improved by very much, I'll bet that area has been explored pretty thorough?

go faster with NEU motor and 5-6 cell lipo 30C of course about 1600 watts

evan-RCU

Already with a Neu, special wind Steve did that is new for him, have a 5 cell 30C in it... I can mess with props but unless new batteries come out that are smaller for the mA I'm stuck for now. As it is it sucks the battery dry fast, even though the airframe is a F5D pylon racer the way I am sucking amps it would not last a 10 lap F5D race... oh, well....

evan-RCU

I'm also working on getting speed out of my F3D plane... Much more difficult to get the motor to work 99%... But this is also good for 220+...

So if you could only have 1 of those 2 planes...........

No question, lekky all the way!!!

evan-RCU

The electric is so easy, once you get the right set up it's really just charge and fly. I still haven't gotten the F3D to run right so it's an unknown, but even once/ if I do the noise and PITA factor will make it a rarely flown airplane.

I've asked a few well known Q40 racers for tips on the motor and most say it's not worth messing with it's so hard to get running right. One even said to just part the plane out on E-bay... One day an electric motor might find it's way into the F3D.

Electrics are the future.

At first glance the only tuning tools you have with the FAI Nelson is compression and the prop.

Castor oil % is a tuning tool, too I suppose.
The biggest drawback when I run mine is how fast it goes through $100 worth of plugs, then throw in a snapped carbon prop every 3rd flight.
It is an amazing engine but not designed to shoulder any more prop load than X amount. I see you are working with Eliminator, that guy's got a nice selection.......I don't know how tuned in he is to RC Speed but there should be a prop in his listings that is close to perfect for lots of combos.

Blowing out the header seal is problem #! for me. If this seal isn't perfectly tight, there is no chance to get a good run. The replacements I got from Pspec don't work.

evan-RCU

I just put a nitro head on it so I can try some nitro fuel. The props I have are what came with it when I bought it. On 80/20 I couldn't get it to unload with the Eliminator props I have. Where can you get them from?

My Feedback: (3)

At the NASS [North American Speed Society] website they have a list of suppliers. You can also do a direct search for Steve Wilk on google.
Imagine running one of these engines on a C/L speedster with about 24 inches of span?

Sorry to threadjack!!! But is that LMS in the background? I didn't know there was a airfield there!!!

evan-RCU

Yes we have a club field at LMS.
