I moved the motor forward to the design position plus 6 mm just to make sure, which involved extending the battery hatch. The ESC has been moved as far forward as possible under the motor as I wanted to make certain. The Cowl needed recovering which is now done and it's ready to fly again. It does not look as pretty as it did due to the patched covering which makes it well and truly my Winter hack. Steve

What is A2(V) powering? It gradually drops starting at 7.5 down to 6.0 just before the crash.

I agree, the gel filled IDC connectors are very good when used in a static, very rarely disturbed, situation. But sometimes I would use soldered heat shrink joints just to make sure. BTW they are not crimped they are Insulation Displacement Connectors so are not the same as the reliable crimped connectors that are often used. Steve

Having flown the Ohmen for some time now it's now in the workshop for repairs. I am taking the opportunity to make some changes and sort a couple of self inflicted issues. I have been practicing for the B test with it and due to my lack of rudder experience I used rudder trim to achieve vertical flight for the stall turn. This works and gives perfect infinite vertical flight but the stall turn only works one way, the opposite way to the rudder trim. Sorry Peter but due to my lack of experience I am putting in 2 degrees right offset on the motor. In winds above 10 mph it will not taxi back so I am changing the skid for a steerable tailwheel. I am in the process of extending the nose, yes I should never have shortened it by 15 mm, my hope is that none of the 80 grams of lead will be needed in the cowl. There is also the option to move a servo from the tail into the fuselage, we will see how the plan works out. My final change will be to put the C of G at 25% of wing cord. I started at 30% and have gradually moved it forward. Whatever you have been told before about a safe starting point for the C of G being on the spar is not true for Peter's designs. At 30% it flies but has a horrible habit of dropping a wing which means it has to be watched constantly. I fitted a stabilised receiver, which cured this tendency but as I moved the C of G forward the bad habits disappeared and there was no difference in the way it flew with stabilised switched on or off. It's now a joy to fly or was until a landing on Tarmac turned into acrobatics. Steve

Greg, Looking at the video above the flight battery is connected first then the Tx is switched on. This goes against the normal safe procedure of Tx on flight battery connect then flight battery disconnect and Tx off last. The video shows that when the flight battery is connected nothing will happen until the Tx is switched on and gyro initiated, return home set and finally the throttle is moved from min to max and back to min. The throttle being at maximum when the battery is connected is dangerous and indicates to me that it's faulty. I would contact the supplier for a replacement. Steve

We are not far apart with me being in North Lincs. Bridlington was a day trip either with the family or sea fishing on a cobble boat with Dad, some 60 years ago. Obviously as you send the cold north wind to us it is the same wind, a lazy wind as my Dad calls it because it goes straight through rather than around. In the shade here the frost has gradually built up.

Every day this week for one or two ten minute flights with The Ohmen, its's a joy to fly in a wind over 10 mph. I started practising the B manoeuvres with it.

Three flights in the bright cold winter air. The Ohmen has become my winter model as it handles the wind well. Steve

Same here, so cabined up talking and drinking tea. Frost this morning, so a late start for me.

Mass build 2023 Peggy Sue 2, 0fourniner E, finish Hound Dog or finish x-RES. My thinking is finish x-RES by which time we should have warmer weather for Peggy Sue 2 build. The rest can wait. I forgot finish Rhapsody and start Destiny. All planes but which one in what order, not an easy decision. Steve

and a Nihm charger?

Recommended setup by 4-Max

Wing centre section covered. now I can fit the wing to the fuselage and finish that. Spring must be on the way. A bit more to do to the wings though, fit spoilers and tip fixings. Steve

The link shows the prop as a 15x12.
