Awesome! Pushing the limits and resetting the goalposts again. Giving the cameracrew a hard time. Clever camerawork too! Thanks for sharing.

I haven't tried micro balloons. Should I give it a go?

I've used 'Spackle' (isn't that a quaint colonial term) for filling dings etc. but microballoons is used to bulk out epoxy resin making it lighter and probably more importantly, easier to sand if necessary.

Just a suggestion. Reduce your aileron throw and/or add expo to smooth out the roll response.
You were absolutely right.and what a numpty am I? I thought I had set up my tx with expo but when I checked all channels were set to Linear. Expo is definitely the order of the day now....flies much more smoothly. Thanks for the help.

Glad you discovered the pleasures of modest control throws. It all depends what you want to do. For smooth flying, relatively small throws work well. For extreme flying, big throws are fun and can be tamed with lots of expo. Just don't forget to change rates! On many of my models I use a triple rate setup with mild, lively and wild settings all worked by a single switch.

I'm a great Polaris fan and am very much looking forward to flying the Mako.

I have had 4 runs on the snow and can not get it on it's nose, I rechecked the low and high rates and found I can only get 1" on high rate for the Elevator. I have DX8 using 5g servos and can get high travel everywhere else so I pulled the servo and set a new one and set the servo arm one notch forward and got the 1.25 travel however I only have .750" the other direction.
What am I doing wrong?
Thx'S

Make sure your using the farthest hole at the end of the servo arm. and the center hole on the elevator horn. You may still have problems getting it to hand stand on the snow if its hard and slippery.

You can also add more travel by programing your DX8. go into servo setup and adjust the servo travel up to 140%.

Are you sure the hinge on the elevator will allow that much throw. It's very common with the beveled arrangement for throw to be restricted in the down direction.

Hi Eldorado4,

aircontrol is correct that by going into your programming you can increase the servo travel. You should also be able to adjust it to go more in one direction than the other so you can add more "down" elevator without needing to add additional up. It helps also with nose stands if the snow is a little wetter or stickier.

You *could* also do a elevator to flaperons mix on a switch. Double elevators! I tried this with my EF 48" Extra for extreme walls.

That can make a big difference in the air with a delta but I doubt it would help with the handstands on the ground. The lever arm of the ailerons acting as elevons (not flaperons, which go the opposite way) is much less than that of the elevator. Even more important, the elevator is in the propwash, while the ailerons/elevons are not. So no action when not moving fast.

A setup using coupled elevons and elevator (both moving in the same direction) works well on Polaris and should also work on Mako to enhance pitch control in the air. In both cases you have a delta wing with the trailing edge well behind the CG.

The setup on an Extra is quite different, as the control surfaces on the normal wing are quite close to the CG. Hence the result of flaperons (which go down when the elevator goes up) is to increase camber and thus lift. This setup was widely used on control line stunt models and allowed "square" corners to maneuvers.
