I know some dont like my scheme, but Im not a fan of that caymen scheme in any color. It looks like a paint job a chinese knock off EDF would use. Further, its a scheme I could paint myself which says something.
But to each their own. Mine will need a new paint job by the 5th flight with the luck IM having.

Back to our regular schedule postings.................

Congratulations to Chad Northeast and Jason Schulman on the TOC placing in Tuscon. Great flying.

Here's my setup with my Map holder ahead of the six liter tank, I also placed my electron gear pack beside the map for balancing.

I ordered some of that Viton tubing from McMaster car, comes out to $10 a foot! I tried using BVM clunk like 6mm but it wont let clunk reach the front of the tank (the big digitech clunk) as the line binds on the side of the tank. Im wondering I should remove the orings off the clunk as well.

Its still going to suck significant air when the tank is 1/2 full and I rotate upside down or do a dive. Im hoping the new tubing will fix it. If not, I do not understand how no one else has this issue unless they dont fly upside down or do long dives.

Just to prove I know how to fly This is my jetlegend viper (now BVM). This is a bit more calm of a flight than usual but you can get the point. I have a intairco UAT and 3 tanks and I land with only a 1/4" air bubble in the UAT.
I know everyone loves the rebel, but this viper is far superior. It wont fly as slow, but its way faster and has a wider envelope, plus I can land it at mock 2 and it will just stick to the runway!

So did you try the 8mm fuel clunk in your system, the 6mm fuel clunk


Here's the 6mm clunk which isn't big enough for the flow for large engine like our.

I got the 8mm and ordered some 8mm ID 10mm OD viton tubing. Ill use the 8mm clunk line for the vent.
I also mounted my filter vertically this time.

When you dive, if you have throttle up 3/4 or full it will slip air no matter what you do.
After half tank I limit my maneuvers in order not to get as much air into the MAP tank.
Also I cut the throttle to 1/4 when coming down from vertical descents and apply the throttle just before or near the bottom of the maneuver gradually.
It's Much easier on the airframe and it doesn't rush you into your next maneuver.

Skunkwrks

I alot of pilots like the 45 degree angle mount as it allow a place for the air to go and is better than horizontail.
Haven't seen too many mount the MAP vertical .

Definitely agree with you, I used Intairco heavy clunk 6mm and I have installed them in event K260 system (many’s K210) and all of them work great……

‘’the nipple on the motor is 4mm LOL

Dansy

My Feedback: (53)

No not many but that work as well…..I have done it in jet that didn’t have the space…

Skunkwrks

Yes, can you imagine the flow and pressure that 4mm line is under? Dam

Your stating thing that have factual truth…..doing down line At ¾ throttle…..that’s not F3S, .that speed demon, you won’t get constant speed because there’s no way you can climb at the same speed….basic pattern stuff..

‘Yes they do….6mm

I didnt take a photo of my UAT after my flameout but I did take a photo of this air bubble. Is this too much air to be trapped in the fuel filter? I had it hnorizontal instead of vertical. Im 99% sure this did not come out of the UAT it ended up in there post UAT. So it sucked it from somewhere maybe the cut off valve or it was trapped in the filter and came out. thoughts?

By looking at the list of jets you own…I would assume you know how to setup and prime the system pretty well, but in case…here my taught..

‘’With Festo and Pisco connection, the tubing has to be cut perfectly 90* or there’s a chance of air leaking…..I also try to go into them square without a bow like at your valve in the picture.

When I prime with these filters….I prime extra long….and wiggle the filter a lot until no bubble come out of it, after that it’s primed and never have to do it again…..the first time you put fuel in any UAT or filter it takes a little time to take all the air out…the position of the filter has nothing to do..I have installed them in different attitude…..but horizontal is harder to prime correctly.

But I doubt the air bubble showed actually come from the filter it’s very large, unless you didn’t prime the motor and just started without prime ?? It look more like an air leak in a line…??

I think this is the key right here with the Festo and Pisco connections.. can’t tell you how many times I’ve looked into peoples planes and seen “strained” connections.

Skunkwrks

Note the fuel nipple on the engine is a swivel so you can turn and make the line straight. Square cuts on the tubing is very important fo sealing plus making sure the tube is into the fitting helps.

Hello

I'm starting my Rebel Pro build now. I could use some help with the flap servo and arm installation. What is the servo arm length that is commonly being used and is the arm attached pointing up or down?
Some pictures of your installations would be appreciated.

Thanks for your help

Skunkwrks

Here's my setup with the Carf 3mm rod attached to the 1" arm, which gets 55 degrees of travel.

The important thing here is that, at full flap extension, the servo arm (regardless of length) should be as straight as possible such that the pushrod and servo arm are a straight line. This relieves the load from the flap off the servo gears and motor.

Skunkwrks

Agree, I didn't have that photo but saying that my servo arm isn't 90 degrees to the servo at full flap . More like75- 80 degrees and if these 600 plus oz servos can't handle the strain, then it's time for more powerful ones Scott.
It requires more mechanical force when the arm is at 90 degrees to the servo. The servo could stall from pushing so hard. Just saying

Honestly the control horn will pull out or the flap will break off long before a 400 oz/in servo stalls in the air. 25 lbs of torque is stupid strong and probably could fly a full scale plane.

causeitflies

Yes, the bigger concern would be how many amps it pulls for how long. With the arm straight it's zero.
