Robert’s new throttle.

Black wire is ground, red to the coil, the other two blue and yellow to the electric start relay.

My first impression was, “this is too big for my hands. I couldn’t reach all the buttons and controls unless I could changed hand position on the fly.

But… The biggest issue on my mind, was that, the throttle was going to be integrated into the brake handle. Which meant, that, I wouldn’t be able to modulate the motor while using the WTS.

And… With my current wing, (APCO LIFT EZ), the WTS is what you use when in reflex mode. The brakes are forbidden and using them in Reflex mode could well cause a collapse. I suppose, you could hang up the brakes, set the RPM and fly that way but it would be a different style of flying. No backing off the throttle when coming out of a hard turn to dampen the bounce.

How hard would it be to disengage the brake lever to use the WTS? It would probably mean another strap to attach the throttle to the hand, the same as a conventional set-up.

I fashioned a strap using one wrap and an adhesive backed piece of “male” Velcro attached to the body of the throttle. Moving the strap around the handle I was able to find the sweet spot that put all the controls within easy reach.

The twist ties are not necessary. The brake handle nestles into its groove nicely. I don’t think the throttle would fall out of the brake toggle, even if it were hung in the risers. Yet… it can be removed easily, allowing the pilot to go to the WTS.

Day 2

This morning after a nice sunrise flight, I started the swap. After a trip to the hardware store and a few bruised knuckles, I was ready to test it…

First attempt was a huge success. It started right up and the kill switch worked. The second attempt was a disaster. It took awhile to figure it out. What happened was, the start button failed and stuck in the start position. I think the machine is alright, the starter was red hot but I was able to pull the battery cable before it burned. I spent the next hour removing the throttle. I wanted to reinstall the old throttle but it needs a new brake cable that won’t be available until tomorrow.

I’m returning the unit to Robert and look forward to seeing the next generation.

Update… the job is done. Three layers of metallic gold and 3 coats of high gloss topcoat.
