The MKS servos are perfectionists when it comes to being in the commanded position.
That is a very good trait for a servo to have.
However, if you have any tight spots in the RDS, this could cause the "jumpiness" people are referring to.
If it were me, I would pump some dry lube into the flap pockets where the wiper works.
Especially on a new plane, and especially on the flaps.

Flap RDS really should use a linkage that either telescopes or is allowed to float up and down at the hinge line (IMO), IF the down flap exceeds about 60 degrees.
The bend of the wiper should be further aft when the flap is far down than when the flap is reflexed. That is fact, not opinion.
The Pike is a great plane. It flies GREAT.
I would NOT use a five cell pack with the MKS servos and RDS.

For your information, Benjamin Rodax answered me on the FAI wing+tail area of the Pike Precision:

"The FAI projected area of wing & tail is ~65.193dm2 resulting in 4.887kg MTOW."

Cheers,

Pierre

Hi guys , flew my precision at the cape, down under, yesterday in a stiff breeze of 35 knots.New 4cell pack and all went great with the plane moving well. Full ballast!!The trouble with my right ron is no more, flying the Precision in heavy weather is what I live for One of my mates showed up with a cyril, both planes running on par with each other.(pike looks better).

I was running 2mm of reflex on all of wing it felt like I could not "press out" of the turns??
I turn the reflex off and noticed a big change in performance, the plane felt like I was pulling more"G"s, plus flying much faster.??

F3Fcurrently 3rd-4th in state so any info to get my Precision going faster would be great. Im no pro just giving it a go. The foza lifts and cyrils are the ones to beat down under.And I know the pike can do it.

Cheers Chad from oz

My second pike is here.

You probably don't need any reflex, but if you do, I would guess it to me much less than 2mm.
The section doesn't have much camber to "get rid of" in speed in the first place (like most of the current F3B planes)
Try between 0 and .5mm at the root of the flap.

2mm seems like a lot.

I got a chance to fly my Precision on Practice Day at the World Soaring Masters off short zip start. I am still amazed at well this plane thermals yet how fact it is when you want to get it moving. I was fortunate enough to get to let Joe Wurts play with it some as well and between him and Mike Smith got it set up really sweet. Mike gave me a nice tutorial on programming my SD-10G radio in the process. Thanks to both Joe and Mike for the help. I still have not got a chance to try the plane up on the slope but hope to next weekend if weather permits.

See Ya,


Pat

Thanks Pat.
That will be helpful to a lot of people here.
If you can, give all the camber settings for launch, thermal, cruise and speed.

My settings

T,

Here are my current settings.

Reflex: 1.5 mm
Camber: 5mm on a slider so adjustable.
Launch: 9.5 to 10 mm
Snap flap: 6.5 mm at full up elevator

I still have very low time on the model but this how Joe and Mike programmed it. Unfortunately we did not get a chance to have either one fly it after they programmed it to get their comments. It seems to fly darn nice to me with these settings.

See ya,


Pat

Thanks Pat.
Not sure if the 1.5mm reflex for F3B speed will be a direct translation into the best setup for the F3F course.
I appreciate the setting info, I don't own one of these lovely planes yet, but if I sell some dust-collecting toys, its definitely near the top of the list.

With paint schemes like FLY N HIGH posted, its sure tempting!

Thanks for checking your setting,Im running very close to the same but will take your info on board.My snap flap is 4mm at full elevator also the snap does not engage till Ive got 30% elevator on. I do this so that when the plane is running between bases it tends to run a smoother line.
