  1. Hi My original post is from quite some time ago and as I now produce the models as kits the only one I am prepared to give you a PDF of is the Buckeye. If you want a copy let me know and I will sort one out for you. Where do you live? I use a particular EDF unit that I make and sell but it might be to expensive to ship compared to the cost of the unit. Regards Eric
  2. Posted by john kennedy 4 on 27/02/2017 16:29:06: Hello. I see that spektrum gear is the most popular radio in the recent poll. I bought my dx8 in about 2011 and is dsm2. Soon after dsmx came out. Just wondering how many still use dsm2 ? I have had odd glitches,including one resulting in a total write off. I don't know for sure what caused the write off but I never feel at ease using the set. Can it be converted? Will I be able to sleep at night if I do? Should I go Taranis? Would like to hear from others with similar concerns .. John John I bought a DX8 when they first came out and as yours it was DSM2 only, however a few months later when updating the Airware all DX8 transmitters were capable of operating on both DSM2 and DSMX. If you registered your transmitter and have kept the Airware up to date you should be ok. The later DX8 version 2 which has the same Airware as the DX9 and DX18 and all the latest transmitters is DXMX only due to the change in radio regulations however your transmitter will have grandfather rights and able to operate either in some ways better than the later model. Even if you have not registered your transmitter and updated your Airware it should not be a problem as I recently bought an early DX8 registered it and updated the firmware the updates are transmitter specific and the update will only work with the registered transmitter. Hope this helps. Erics
  3. Anyone remember when we used to be registered i.e. had to buy license for our radios why not just apply that? License number to be shown on all models, when anyone purchases a radio must include their license number to retailer in to complete purchase, radio licensing authority to have a list of retailers and importers however small and do spot checks.
  4. Here are a couple of videos of the models flying.
  5. If anyone wants to try any of these models please pm me and I can send a pdf for personal use only of those that I designed and made, I can possibly supply the Viking fuselage. The fans you will have to source.
  6. Info about our St.Helens indoor flying group EDF models most are profile models and powered by 1s EDF 30mm fan units salvaged from old Silverlit or Airhogs models. The first model built was the FJ1 Fury by myself back in January 2014 and since then other members of the group have been busy. We have found that if you can keep the weight down to 26gm including the battery they will fly quite happily on a single fan unit using a 220mAh LiPo.Above that and you have to either add an additional fan or go to a brushless motor. All of the models are about 16" span and built from 3mm depron or aero depron. The Buccaneer is 18" span weighs 70gm and uses 2x30mm GWS fans with 1s brushless inrunner motors each motor draws 2A and so a 300mAh cell is used. The S3 Viking uses 2xSilverlit fans with 1x 220mAh cell and has a moulded fuselage and weighs 40gm the details of the moulding technique are on an RCgroups thread. The Viking flies for about 6-8min on this battery and has a steerable nose wheel, the slats and flaps allow it to fly slower than the original test profile model also shown in my album. "Streffs Indoor Album" If you want any more information please feel free to reply to this thread or pm me.
