    Hi Ton, Photos of My Lord as promised. Build was straight forward but finishing took longer than I expected because of the good flying weather. The colour scheme is based on my stock of Solarfilm (now all used), and trying to get a contrast with the countryside around the flying strip. Maiden flight due this week if weather allows. Corby is out of action at moment.

    Hi Ton, I have completed the aileron conversion,! and have taken before and after pictures which I will forward. The structure is now finished with only the covering to complete. I hope to have the model ready for flight within the next few weeks. Regards, Roger

    Hi Ton, Thanks for your prompt response. There are some pictures taken during construction which I will forward to you when I upload them to the computer. I had hoped to have the model complete by this time but Christmas and holidays got in the way. Regarding the reasons for wanting ailerons - 1. The motor for the model is from a Scale Extra 330SC aerobatic model and is rated up to 350 watts. For the Lord I will fit a prop that will drop the power to around 275 watts which is still over 100 watts per pound. This will provide plenty of power and I want to be able to control the model. 2. After 17 hours of air time my Red Eagle powered glider has suffered a broken fuselage following an unintended half roll and subsequent crash from about 5 metres height. The half roll occurred when powering up to climb. The model was turning into the wind, but I suspect a gust of wind hit the model from the side. The wind direction on the day was varying up to 180 degrees. However without aileron control I could not stop the roll until too late. Regards, Roger

    Hi Ton, I have built the model generally as per the RCM&E plans. Unfortunately balsa sizes in NZ are generally imperial which was a bit of a problem with the fin, rudder, tail plane and elevators. Had to laminate imperial sizes. However I would like to incorporate ailerons. What size should they be? Are there any structural changes that need to be made to avoid the wing twisting under load? From my investigations on line it looks like the ailerons would probably be about 275mm long and 50mm chord to match the existing wing structure. Any comments would be appreciated. Best regards, Roger Mason New Zealand

    Avspecs have produced two fully airworhy Mosquitoes which have been delivered to collections in the U.S. Rumours exist of more orders. Videos exist on YouTube. Have seen both of them flying and managed to get into the cockpit of the first one during construction. One of our club members works for Avspecs and club members have been invited a number of times during the restoration.

    Hi Ton, You must be working late. Thanks for suggestion re battery. I have put a spacer at the back of the battery tray which brings the battery forward about 6mm, and have also fitted some thinner wheels so we will see how that goes. Will let you know the results, possibly by end of week. Many thanks. Regards, Roger

    Hi Ton, Thanks for your message. The CofG is as per the plan. Adding weight to nose is possible, but I did note that the model was perfect on a glide approach, which why I went for thrustline changes. However I will try some weight on the next test session. Good idea about thinner wheels. Club members have made favourable comments when the model is in the air. Regards, Roger

    Hi Ton, Finally the weather is suitable for flying. Have maidened the Starlet but had to add side and down thrust to make it flyable. Remaining problem is to do with control throws - elevator is very sensitive but I need a reasonable amount to keep from tipping over on takeoff from mown grass field. I am investigating a couple of options to provide enough elevator authority for takeoff and landing flare but give reduced throw for normal flight.

    Hi Ton, Thanks for the comments. The build was interesting as there were a few different techniques which required thinking about before acting. The ply and balsa materials had to be a nominal 75% thickness to keep the weight down. I left the wing ribs at the same thickness for ease of handling, and the fuselage sheeting in front of the cockpit had to be planked because of the dual curvature. The motor was going to be a Dualsky 3530 1200Kv but, because a noisy bearing, a Dualsky 3536 1200Kv (maximum 350W rated motor) was installed (same mounting holes). A 30A ESC was fitted along with a 3S 2100 battery. Static current draw on a 9x4.5 prop is 18A (approx. 200W) which gives a power rating of just under 100W/lb. This is very close to one of my aerobatic models so should be plenty of power. Will let you know about the maiden flight - could be this coming Thursday or Friday if the weather plays its part. Regards, Roger
