one Girl's Rave ENV Build or "pink my Rave"

[Tim Procter]

First flight of the Rave

No 3D (like I can 3D anyway!)

but you can tell from the video that he was very locked in .

the first 30 seconds wern't in idle up.

Align starters.. Say no more..

I we left that bit in because I thought it would give a few folk a laugh

In all fairness that's the first time its let me down but a dynatron on 14 volts wouldnt start it either
It took the full 22 Volt monster dynatron to start it.

Tim you might be able to help with this one , my friend pulsar's rex 700 topstart keeps slippinbg in the one way is there a cure ????

I ask you because you seem to exist to fly (like me ) and have a huge experiance .

If you mean slipping when trying to start it there could be one of two problems..... and yes mine does it too in cold weather.

1: The one way bearing could be slipping.

To solve this reduce the power of your starter lipo, too much power in the Dynatron wrenches the bearing to bits. I went from a 6s to a 4s and that sorted that.


2: The one way bearing collar will be turning inside the one way bearing cover. (see this on page 9 of the manual)

To solve this and save yourself £50 purchasing new, extract the bearing collar from the one way bearing cover and glue it back in again.

Done this with two of mine now. Total success.

Looks good

Not sure what it is with the Align starters, I don't have a problem starting my 700 but on my Rave it doesn't seem to want to turn the engine over. I eventually get it started but I put that down to subborness

[Buzzin Brian]

Its all that muscle!!!!

I am glad to see you got that bad boy going Rachel. Now get out and fly it like you stole it!!!

Drivers wing and indicator just sold

more parts for the rave then

Rachel,whats happened to "Dave the Rave" is he o/k what is "Santa" bringing him for "XMAS".

WOW it's been ages since I updated this thread sorry for that it's my intention to keep it updated with my flying progress and keep all "Dave" fans advised.

So what's happened ~~?
well My S/H engine blew up on the 5th flight new liner , piston and ring plus bearings humm not cheap I am sure it wasn't a deliberate act by the seller just poo luck .

this showed up the fab design of the rave engine out in seconds, skids stay, bottom plate stays, just 4 screws split the cooling shroud, 4 engine bolts out , 2 exhaust both , throttle linkage , fuel pipe done
That's the fab thing about the ENV its all so well thought out.

I changed the paddels to KBDD ones which speed up the cyclic really well but at the loss of the wonderfull locked in feeling Dave has.
So they are going and I will try some align ones and maybe a different flybarlength, see boy's any girl who tells you size dosen't matter is lying
I personally love the locked in feel of the standard paddels but find for me ,it's a personal thing and I have to push the stick too far to get the result I want.
I know there is a top UK pilot working on this so hopefully more soon but as I say it's a personal thing.

More later but for now just to say I love my Rave .

It has been a while since I last visited. Sorry Rachel for the two incidents but I'm glad you got "Dave" flying.

In thoery it's the weight of the flybar assembly that affects the flybar's 'authority' and then the shape / size of the paddles that gives you the control feel.

I have some paddles that are very similar, nearly identical to the KBDD and they are very aggressive due to a sharp airfoil and rearward mounting position but they have been the best balance of stability and response when used with some flybar weights (this is on the Robbe Futura). But without any weights the flybar lacked stability in the wind and a steady hover was a bit of a chore.

I recently got some Minair '3D' paddles that are a little more rounded shape. I haven't had a chance to try them beyond just hovering due to the weather but I think they will be good.

The Trex 700 flybar is quite a bit longer (than the ones on the Robbes, for example) and they get away with very light paddles, so that might acheive similar results.

I don't agree. If that were the case, the mixing ratios in the upper mixing arms would work reveresed to how they work. (This is fairly clear in the G5 manual.)

However, if the flybar is too light, it may not work so well - ie may precess due to the reaction from the links.

My pet theory (FWIW), is that you're interested in how fast the flybar precesses, compared to the main rotor disc. The flybar should be significantly slower. If you speed up the flybar presession (eg lighter, more agressive paddles), you may need to speed up the main rotor precession.

If you (Rachel) just wants to change the stick response, I'd consider whether swash mix &/or DR/Expo can do this.

Or a higher head-speed..?

you already had what you wanted in the form of a total g but you removed it !! a stable locked in feel but with faster cyclics = "flybarless"

I know I really am upset at not going flybarless and removing the Total G Flippin' JR servos ,..........

The Total G is in the Vibe unflown yet But my plan is to learn with the vibe and then put a cheapo unit such as a beasy x on it and reinstate the Tg on Dave.

But for now under the wing of Mat at Midland (yes the one that looks like ****gy off Scooby Doo ) I have fitted a longer Avant flybar and Radix 105 paddels .

A test flight in 35mph + winds didn't tell me much , but on the advice of one of my club members I refitted the paddels so the leading edges didn't face each other

Second again very windy flight fellt better but too windy to say .

I will post when I have flown him again

Hugs XXXXXXXXX Rachel

What I stated is correct. I think you are confusing the inherent stability of the flybar (which is a function of it's mass and speed) vs the mixing of control authority between the swash and the flybar.

There is a good article on this by Colin Mill which can be found here; Model Aircraft and Model Flying - W3MH - Home Page

But it's a bit of a moot point really because I know Rachel would rather just get rid of the flybar anyway
