aidan mcatamney Posted August 4, 2023 Share Posted August 4, 2023 You will love them Toto. I've been using them for a good number of years now and they make life so easy . As I said in the above, I use the 14mm servo screws for fixing servos in the plane and I use the 16mm heavy duty servo screws for bolting down the saddle straps that hold your landing gear in place. 1 Quote Link to comment Share on other sites More sharing options...
toto Posted August 5, 2023 Author Share Posted August 5, 2023 So, Should be back in the shed tonight after what I hope will he a day of flying my Arising Star. It should he her Maiden today all going well. Tonight it will he installing the electrics, ESC, receiver etc , doing a few checks on the servos and testing things out. I still need to look at my dodgy push rod installation for the rudder and elevator control horns as yet. Not sure what is going to become of that. ..... maybe .... tonight will reveal that secret. Let's wait and see. Hopefully report back tonight. Cheers Toto 1 Quote Link to comment Share on other sites More sharing options...
toto Posted August 14, 2023 Author Share Posted August 14, 2023 Dubro 3.5 inch low bounce wheels fitted in exchange for the stock items. Hopefully these will cope better with the clubs grass and tarmac landing options. That's all for now. Toto 1 Quote Link to comment Share on other sites More sharing options...
toto Posted September 7, 2023 Author Share Posted September 7, 2023 So, I had my mentor / instructor around for a visit about a week ago. Whilst he was here he took a look at this Phoenix Eap 60 and my issue with the dodgy elevator pushrod scenario. Looks like I will be changing the pushrod out and refitting the horn to be at 90 degrees. This will require double offset in the rod and filling in the previously created holes for the horn. I think I know what I am doing now to get this assembly over the line and ready for setting up for a maiden. I'll be back in the shed at some point soon to do the remedial works. I'm not sure if I will get away with straightening and reusing the same push 4od or if I'll need to buy two new ones, we'll see. ..... to be confirmed.

toto Posted September 7, 2023 Author Share Posted September 7, 2023 Ok, a mixed bag tonight. I removed the previous attempt at the elevator push rod assembly ...... which looked like .... this .... and the geometry was clearly incorrect. So off they came and new holes drilled for the horn to straighten it out .... as you can see i will have a repair to do on the covering .... no big deal. lined the horn up with the centre of the elevator join .... and the same with the other side ..... but ...... the push rod bends left a lot to be desired ....... a real dogs dinner ...... so ....... I'll order in a couple more and make a decent job of them. i don't want to mess around with them any more as they will end up looking even worse and for a new model ..... it's not on..... so replacements will be sourced..... what a mess.☹️ never mind ... as soon as I get the replacements and get them installed properly ...... we should be ready to set the servos up again ready for putting forward for a maiden. that will give me this model and the Domino ready for test flights / adjustments etc. thats all for now toto. 1 Quote Link to comment Share on other sites More sharing options...

Outrunner Posted September 7, 2023 Share Posted September 7, 2023 Toto, have you thought about fitting the elevator servo at the rear end and dumping those awful long pushrods? Quote Link to comment Share on other sites More sharing options...
toto Posted September 7, 2023 Author Share Posted September 7, 2023 Hi Outrunner, That's a thought. I would need to have a look to see if there is a suitable location for fixing them to. I had been thinking that even if the long pushrods had worked out, it must be exerting a bit of stress on the servos. Two angled bends and a diagonal run over that distance can't be good in general. I'll have a look and see what can be done ...... good shout. Toto Quote Link to comment Share on other sites More sharing options...

The way I have the elevator rods connected have kept the plane flying well at this angle. Hope this helps. Quote Link to comment Share on other sites More sharing options...
toto Posted September 8, 2023 Author Share Posted September 8, 2023 Hi Aidan, Am I correct in saying that your rods have not had any additional bends built in ? They look pretty straight to me with only the horns slightly offset but still above the wing joint line. Cheers Toto 1 Quote Link to comment Share on other sites More sharing options...

There are no additional bends built in and the horns just slightly offset. Quote Link to comment Share on other sites More sharing options...

GrumpyGnome Posted September 8, 2023 Share Posted September 8, 2023 The servos where they are, with long pushrods, will be absolutely fine as long as the wires move freely. That saves you cutting holes in your fuselage, potentially weakening it, and removes any balance issues. I'd leave 'modifying' kits until you have a little more experience. Just my opinion of course. 1 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 8, 2023 Share Posted September 8, 2023 (edited) I agree with GG, maybe fitting rear mounted servos is a ‘bridge too far’ at this stage. However an alternative, which is fairly straightforward to fit, is a pushrod transfer arm - SLEC I would suggest against a pushrod without any bends in it as it would rub on the exit slot in the fuselage and it would also curve out to the horn. Any unsupported curve in a pushrod is to be avoided as this can introduce flex allowing control surface flutter.

Peter Jenkins Posted September 8, 2023 Share Posted September 8, 2023 The other thing about moving the elevator servo to the tail will mean the CG will be moved rewards. It might still be an OK position or might not. You would need to check to see if there is a range of CG given. Worst case is you would need to add weight as far forward as possible to bring the CG to an acceptable position. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted September 8, 2023 Share Posted September 8, 2023 Keep pushrods straight if you can, don't obsess about the hinge line for equal movement, you can sort that via TX. 1 Quote Link to comment Share on other sites More sharing options...
toto Posted November 10, 2023 Author Share Posted November 10, 2023 I've just ordered some snakes from SLEC I have them in the SKY 40 and think they will work well here as well. Cant he any worse than what I have. I'll get them fitted when they arrive and try them out. I'd like to get this header finished and set up properly. My mentor can do shy test flying for me just to confirm all is well. He done a great job of advising with the final set up of the Domino just before maidening Toto 1 Quote Link to comment Share on other sites More sharing options...
toto Posted November 10, 2023 Author Share Posted November 10, 2023 Just done the power conversion on this. Weight is 3.8 to 4.2 KG which equals about 8.5 to 9 lbs So this would be requiring about 900 watts of power at 100 watts per pound of weight I'm running it on a rimfire 60 80A ESC 6s 5000 man batteries. I need to look back at the recommended prop size for this and get it set up on the stand to check it out on the Watt Meter ( my new best freind after John Smith and my Icelandic mate ).

toto Posted November 10, 2023 Author Share Posted November 10, 2023 Had a look on a a prop sizing site and they say 11 x 6 to 12 x 8 for the 0.60 size model. That could be a good enough starting point in which to try out the Watt Meter on. I'll likely try both as I am sure I have both sizes available on APC e props. It might be a 12 x 8 that is currently on it, albeit a master air screw prop ..... I'll check. Toto Quote Link to comment Share on other sites More sharing options...

I imagine your prop sizing site represents i.c Quote Link to comment Share on other sites More sharing options...
toto Posted November 10, 2023 Author Share Posted November 10, 2023 The size was given against an electric equivalent but I can double check. I 've forgot the site already but I'll find it again. I know ground clearance is not great .... I'll double check that as well. Cheers Toto Quote Link to comment Share on other sites More sharing options...
toto Posted November 10, 2023 Author Share Posted November 10, 2023 OK ..... so .... I'm checking out the tiger 60 set up .... We are using ..... and .... and ...... and ..... and we have this ..... so .... I slipped in the watt meter and here are the results ..... Unloaded ...... 00.00 A 23.90 V 264.5 WP 00.00 W 00.002 AH 00.00 WH 11.06 AP 22.50 WM Loaded with prop running full pelt 13.37 A 22.78 V 409.50 WP 297.00 W 00.157 AH 03.80 WH 17.67 AP 22.24 WM so ..... do the maths ..... for its 8.5 to 9.0 lb weight ..... its only drawing around 35 watts per pound ....... just does not pay the rent..... Prop size ???? toto 1 Quote Link to comment Share on other sites More sharing options...
Learner Posted November 10, 2023 Share Posted November 10, 2023 Try a 14 x 7 and then maybe a 15 x 8 but hold on tight! 1 Quote Link to comment Share on other sites More sharing options...
