John Sheehy Posted December 11, 2012 Share Posted December 11, 2012 I currently have easy OSD fitted but it doesn't have RTH. I want to upgrade to an OSD with RTH. I'm looking for something as compact as possible and using as few radio channels as possible. I've looked at the nova but there is no throttle control, just ailerons and elevator, so I don't see how it can gain or lose altitude. I also don't know how many radio channels it uses. Any suggestions? John. Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted December 11, 2012 Author Share Posted December 11, 2012 PS. I forgot to mention that price is also an issue, I expect to pay around £150 or preferably less. John. Quote Link to comment Share on other sites More sharing options...
John Cole Posted December 12, 2012 Share Posted December 12, 2012 I know nothing about this subject but a quick web search found this DragonLabs prioduct, though it's currently out of stock. Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted December 14, 2012 Author Share Posted December 14, 2012 Thanks John, I spotted this one too but it seems to be permanently out of stock. I've seen Hornet OSD but it's quite expensive with the FY-31 AUTOPILOT which is needed for RTH. One worrying factor is that some of these RTH OSD's use the failsafe to set the throttle at full (or a percentage) so when you get out of range (or flick the assigned switch) failsafe provides the throttle and the unit controls the Aileron and elevator. This is fine under normal circumstances but it means that if you inadvertently switch off the Tx on the ground before the Rx the motor fires up. Very dangerous.

John Cole Posted December 14, 2012 Share Posted December 14, 2012 Could buy from USA. In stock there. Quote Link to comment Share on other sites More sharing options...
John Cole Posted December 14, 2012 Share Posted December 14, 2012 Your points about safety, and Nova having no throttle channel. Maybe that's why. Nova: would not the elevator make it go up and down? Does on my manually-controlled RC plane! Quote Link to comment Share on other sites More sharing options...

Hi John, i have dedicated fpv's one uses Nova osd and the other a fantastic Eagle tree OSD PRO which has been superb even at long range, i could message you more details if it helps as i dont like to share too much of my FPV flying adventures publicly, (great viewing with the family though haha) Have a look at this link from heliguy, ive used them a few time in the past and have been great **LINK** regards, Scott Quote Link to comment Share on other sites More sharing options...
John Cole Posted December 14, 2012 Share Posted December 14, 2012 I emailed Dragon Labs asking about availability. Here's their reply: "They are being held in UK customs, as soon as the postie brings the slip so I can pay the charge they will be delivered next day - I'm hoping for stock by Tuesday or Wednesday Best wishes Mike" Quote Link to comment Share on other sites More sharing options...
John Sheehy Posted December 14, 2012 Author Share Posted December 14, 2012 Hi Scott, I did look into OSD Pro but I was never sure what I needed or what I was buying. I don't know what an OSD expander is, Is that an expander for an OSD unit or is that the unit? Then there are the various plug in units for different functions. I don't know how much space they all take, how many channels I need to set aside or how much the final bill would be. Any help on these questions would be helpful. Do feel free to message me if you prefer. As to the suggestion that I buy from USA, I bought a motor from theUSA about 6 months ago and the US customs took more than the dealer. They took the duty and then charged me £8 for doing it. I don't shop from the USA for that reason. I guess it's not too early to wish everyone seasonal greetings. John.

John Sheehy Posted December 14, 2012 Author Share Posted December 14, 2012 John I don't understand your post. Dragon Labs is in China, how are UK customs involved? Also delivery options are; UPS £57 Quote Link to comment Share on other sites More sharing options...
John Cole Posted December 15, 2012 Share Posted December 15, 2012 Imports: if you buy from outside the Eu then you are liable for import-VAT. Parcels of total-contents value under £15 are exempt (the rules for gifts are different). You may also be liable for Import Duty, but I have never paid this. The international-standard customs form on the outside of the parcel requires the sender to state the value. You then pay the VAT as 20% of this. Royal Mail collect the money, and charge £7 for that service. Quote Link to comment Share on other sites More sharing options...
