  1. Thanks for the info and advice. I shall try to figure it all out when I have got closer to finishing the Rapide. The tiny servos for the ailerons that I received do fit easily into the end of the wings just behind the aileron so i shall give that a go.
  2. I received the hardware from 4-Max and George included a programming card that I had not heard of before. He says it is important to set the “Low Voltage Cut Off” level to the lowest. Failure to do so could result in one ESC cutting power to one motor which would then make your model uncontrollable under power should the battery voltage drop too much. I am not at all sure what to do with it and it came with no instructions. Does any of you have experience of using such a card?
  3. I was looking for micro servos to put in the wingtips and in an ad for a Ripmax type it said "Described as the world's most power-saving micro servo, it draws only 310mA at stall. Suitable for high voltage applications such as 2S Li-Po." Which made me wonder if other types burn out? As for the undercarriage. I just followed the instructions being very careful to make sure I chose the correct gauge of wire. The method I devised to keep the fuselage square whilst gluing the sides together might look crude but it worked. I photocopied the plan and glued it to a board. Then I sawed up the blocks from a length with good square edges and stuck them along the plan. By the time I saw your last message, I had knocked off the board to use elsewhere and have just placed them back for the photo, so it looks a bit inaccurate. I glued in the crosspieces to push the sides firmly against the blocks and used a combination of balsa shims and a couple of temporary solid sheet formers to maintain shape where the top side is narrower than the bottom. I left it fir two days to set hard and it worked well. Hope that helps Ian
  4. Welcome back. I hope I have uploaded my Rapide pic. I haven't worked on it much reently due to house hunting and selling our 2 historic canal boats. I am thinking of installing the aileron servos in the tip end of each wing if I can find servos small enough and matched with the lipo. I need to order the hardware now and tried to email 4Max through their website but clicking on their email tab does not work. I will try telephoning them tomorrow. (if we don't get blown away). Cheers, Ian
  5. Can I ask please about your selection - why you chose two types of servos ? Why not have all lightest weight ones and why mix digital with analog? Will you have "Y" splitter cables connecting the ESCs and the aileron servos?
  6. Another naive question for when you are back off holiday - Do you just revers the wiring on one motor to get one prop clockwise and the other clockwise? An if so I assume the motors are happy to turn in either direction?
  7. Thankyou so much Chris. It is so good to be in touch with a fellow UK Dumas DH Rapide builder - at last. Pat Tritle suggested linking the two aileron servos and the two ESCs with 'Y' cables or were you planning to synchronise them by adjusting the transmitter controls? It is many decades since I built a balsa and tissue model or flown RC and never electric so this is all new to me. Sorry, can't help with the 6x4s but can you explain the use of a standard and a pusher prop - is it the same as contra-rotating props? I am certain will have many more naive questions but I will go through all you suggest and let you know how I get on. Cheers Ian
  8. If you can read this it is thanks to the RCM&E Magazine editor who found a forum person who could save me from 2 days of grief trying to log in to this Forum. The reason is that I found this thread by accident after days of trying to find out which motors / ESCs are suitable for the Dumas DH Rapide kit because - as you have found out - the recommended motor is no longer available. I had a wonderful exchange of emails with Pat Tritle who designed the kit but his suggestions are not available in the UK. I did receive an expensive box of electronics from the shop that sold me the model but that only proved they had no clue about the kit. (motors too fat and powerful, props so long they would have ripped out the fuselage sides etc. So whinge over, please tell me what motors and matching ESCs you used or would suggest. By the way - my good lady wife bought this wonderful kit for me to build over Christmas because it was the first aircraft I ever flew in aged 8. Bea service to the Isle of Wight with a female pilot accompanied by my sister and ex WWII RAF pilot Dad.
