Very sound advice. I feel that with most kits, there's always room for modifying and /or improving the manner in which they are built and flown. You nailed it by saying, in so many words, How brave and willing to experiment are you? Good day

tomcatman, one reason for splitting the control surfaces in two, even though they are moving the same is to use two servos so the digital servos(usually used) don't fight each other.

Many thanks to everyone for their help.

Patrick. Your description of the problem is spot on. When the plane was built, it looks like a servo in each wing was put in the wrong way round.
The easiest solution would be to turn them. Unfortunately the servo hatches are glued in & I would spoil the fantastic airbrush work. Using 4 channels may not be an option, as my transmitter is one of the older, cheaper computer models. The easiest solution ( maybe not the cheapest ) is to use matchboxes.

Hi Jim:

I currently own a HotSpot with over 200 flights on it and my previous Spot has 248 flights on it before it buried itself in the desert a couple of years ago.....

The original design of the HS is for single servo elevon setup(single 4721, 8411, 8611)......i.e. right and left control surfaces function as both aileron and elevator.....

The way that the plane is designed precludes proper operation with inboard elevators and outboard ailerons.....it's been tried and found to provide inadequate elevator control at low airspeeds......it takes a full length elevon surface to provide enough pitch up for proper rotation and flaring.....

The only reason one would saw the elevon in half and servo them separately is to provide redundancy......

You have spotted the problem with the servo orientation.....easiest way to fix would be to use a MatchBox, but allot of guys, including BV suggests not using Matchbox on aileron or elevator, as any malfunction will dump the plane, as there have been failures reported in both the Giant Scale and Jet community.....rare, but they do happen.....

The best option IMO would be to pick up a Reversed Servo for each side....that is what BV uses in several of his designs where he wants the servos to be mirror-imaged in the wings to keep the wing cutouts symmetrical, such as on the flaps on my composite Bandit.....a second option would be to pick up a reversing Y-connector, but that also introduces another circuit in the line, another point of failure.......

I have an electric jet called the Banshee - same issue, you need all 4 surfaces moving for elevator control. Outboards only for aileron is fine, it helps with resolution issues to only have the outboards to aileron since you can have a goodly amount of throw without having either a lightning fast roll rate, needing to dial the aileron % down to 20% and inputting huge percentages of exponential.

My Banshee has programming for 4 seperate servo's. Inboards move as elevator only, outboards move as elevons. The inboards could just as easily be Y'd if reversing isn't needed. It is fairly easy to do on a Futaba 8U or 9C since there is a pre-done program, I'm sure it's possible on JR. If you have the aftermarket Futaba programming guide look for "Space Shuttle Mixing".

Ya, also figure out how to crow them without changine pitch for amazing speed brake action!

jim,, you need to listen to seanreit ..he is VERY right, unless tomcatman knows something that thousands of roo ,rookie,hotspot,TAILLESS,delta,elevon r/c sport a/c flyers don,t.,, which i think is highly unlikely , ,,, no offense tomcatman,your set up may work for sr71 or some other r/c a/c, but the hotspot won,t fly[safely controllable] unless its set up like seanreit said ...period.
