An update. The UK LAA has approved VGs for G-RAEM and the increase of MTOW to 1600lbs - it took a while and a lot of paperwork. Thanks to all who helped.

Hi Marc, I really appreciate your helpful response. We don't have the Experimental category; ours is a Permit to Fly issued by the UK Light Aircraft Association delegated to it by the CAA. Three test flights were completed, one at 102.7 and two at 101.7. Yes, we need to cover 97 to 103. Our 'stall' speeds, 50  at 1466 lbs and 61  at 1600 lbs were all KIAS. I read an article that illustrates the difference between certified and non-certified aircraft as regards VGs, the former being massively more expensive to take account of all their testing. Seems we shall be doing much the same testing.

I need help. I have a Long Ez in the UK and have completed the airtest to increase the MAUW to 1600 lbs. The aircraft is fitted with VGs on the canard and wing (I bought it like this). However, a local difficulty with the authorities means I have to submit paperwork to regularise the VG set-up. I also have to come up with specific CG calculations with min front seat weight. Despite the aircraft having done three test pilot flights, I have to prove the safety aspects of the installation and the effects on 'stalling' speed - it nods at 50 kts. I found that Micro Aerodynamics declare, and issue a placard, of airworthiness provided no more than 5 VGs are missing. I can supply photos of the installation but am short of a suitable/professional diagram of placement and chord etc detail that would satisfy the scrutineers  Can anyone point me in the right direction?

I mentioned a 'new canard on the block' some time ago. The aeroplane is called the e-Go and is factory built under the new Single Seat Deregulated(SSDR) category in the UK. It is  all carbon fibre and powered by a rotary (Wankel) engine. This first aircraft is revealed on 7th June to its owner - me. It is now in serial production, and I am now running the company. It turns like a fighter! Hope we can compare notes when the new canard design is revealed at Oshkosh. We are on We will look to launch in the US next year. Watch this space . Best of luck. Murray44

Good point re the name. The University of Cambridge already has an experimental rig with batteries and propeller. The installation features in one of the early E-go bulletins. Unfortunately, the Single Seat Deregulated (SSDR) rules give a max AUW of 300kg so it will probably have to wait for development  in the 'Permit to Fly' category, where the AUW wouldn't be a problem, but the team are progressive, so watch this space.

Would like to get in contact with any experts in the UK, as I have the equipment to retrofit an electric airbrake to my LongEZ and would appreciate some advice.

Whilst I enjoy my Long EZ (and just fitting an electric nose-wheel), it really needs a reasonably long hard strip. We have a shortage of them here. Now being built to the north-west of Cambridge, England, is a new canard, single-seat, that will operate off 300 yards. It's called an E-Go. Have a look at It doesn't have the legs of the Long EZ, and it can't carry talking ballast, but will be fun to fly. It is factory built, all carbon fibre with a Wankel-style rotary engine, and for those of us with limited spare time and skill, it is a exciting opportunity. The test aircraft has displayed to an enthusiastic audience. I'm sure it will make it to the US in due course.
