Timo, you are making an impresive job with the Whirlwind there!

Wish you the best with the project.

Best Regards,

Thread: Seagull Hurricane Laser
12/02/2020 08:16:54

Jut one question: Are you keeping with the instruction manual C.G.?

I have not read the entire thread but I know well the model from a good friend here in Spain. When he maidened his Hurricane he found it to be too sensitive on elevator just from the take off and, in fact, he damaged the model trying to land it!

He asked me to check the manual C.G. and propose other postion if I found it wrong. What I discovered is Seagull C.G. is calculated at 33% MAC, which is common to my own Seagull models (Gipsy Moth and Bucker Jungmeister) and, which for me is too far back for scale models maidens.

In my own models I switched to 25% and only the on the sweet Moth I have finnally left it at 28% but seeing your problems with your Hurricanes I strongly suggest trying with a 25% MAC C.G . for your next flights.

I do not know if I keep my calculations on the Seagull Hurricane C.G. but I will check and, if so, I will publish them here for your reference.

Thread: Hitec Flash 14 radio is coming?

Seeing FCC application for the Hitec Flash 14 is from August 2017, I am afraid it was a droped project.

Alan, see it just the other way: you have lived to see these full 60 years of RCM&E!

And I wish you to see new issues for many years more.

Thread: OS FSR engines
01/02/2020 20:46:01

I also own an OS .40 FSR ABC with liner flaked, althought it is a 40 years old engine and passed through 3 Omega model planes (old F3A aerobatic trainer), 2 Embraer Tucanos (semiscale model), a RCM&E Gerald Curd´s Bucker Jungmeister and an a Jack Stafford Ercoupe! So I can´t complain about engine longetivity.

I, like "FlyinBrian", also believed that the liner flaking problem was far more recent, from the mid 90´s FX models but it seems clear now that it comes from some years before!

Thread: Peel Ply Issues
31/01/2020 07:32:05
Posted by Alan Gorham_ on 30/01/2020 10:13:40:

After I remove the Peel Ply I just rub the "nobbly" finish flat with 60 or 80 grade Ali Oxide paper and then brush on a thick coat of high build primer and start from there.

Alan could you, please, explain which high build primer do you apply by brush?

I only know of 2 compounds sets intended for professional automotive bodywork and which are for spray painting. I sincerely do not know if they could be applied successfully by brush!

Thanks.

"Dad_flyer" thank you very much for the discovery and the info!

It may be I also go for one. I think the occasion well deserves it!

Congrats, Timo, for the design, the model and the plans being published!

You sure deserve it!

Thread: Futaba T14SG chat
22/01/2020 21:48:07

Michael, the 617 is a FASST 7channel receiver and with this modulation B.F/S is only available for channel 3 (as well as for nornal F/S, while other channels keep on last position received, this is in "Hold" mode).

For FASST receivers you are not able of programming the B.F/S voltage, so the default 3,8V applies.

Sure going the Ni-MH route solves the problem, but go for no less than 1.200-1.500mAh for 4-5 normal servos and no less than 2.000 if your models mount more than 5 units.

22/01/2020 16:30:52

Michael, as you describe the problem it is for sure a Battery Fail Safe activation (no throttle control but normal on the other channels).

Default B.F/S voltage in Futaba receivers is 3,8V and in 14SG you ONLY may change that on FASSTest receivers.

For changing the B.F/S voltage in FASSTest receivers you have to go to "SYSTEM" menu and just to the right of the "LINK" option you will find the B.F/S value. If you change the default 3,8V value, you will have to link again the receiver to refresh this on the receiver memory.

Futaba suggests the following safety voltage values:
• 4 cells NiCd or NiMH (Normal: 4.8v) = 3.8 v
• 2 cells LiFe (Normal: 6.6 v) = 6.0 - 6.2 v
• 2 cells LiPo (Normal: 7.4 v) = 7.2 - 7.4 v

Anyway with a BEC there is no logic on programming a B.F/S as the BEC shoud safely power the receiver and servos even after cutting the motor if the power battery goes too low. If you are getting B.F/S from a BEC unit, sure it is short for the power and number of servos you are using in your model. Be careful!

Thanks to you both sirs, Peter and Tim, for your considerations!

Although not purely "new" (it was built by my uncle Pepe Cardin during 2010-2011), I have been tasked lately to overhaul, repair some damages and test fly this Berkley Custom Privateer, also known as McGovern´s Monster.

Model is entirely built in wood and covered with white and orange silk. Power is from an AXI brushless outrunner motor and a 6S 5.000mAh Li-Po battery. RC equipment is all Futaba with control from a Fasst T7C. It has no more than 30-35 flights although it has never been flown from water yet.

Saved from the garbage bin some years ago, it is the control line Bravo model, the last of the type produced by the Spanish firm Modelhob during early 90s. The original kit box contained the sheet balsa model together with adhesive decal sheets, glue, a Cipolla 1,5 glow engine, control cables and handle, a small fuel bottle and even a dry cell for glow power. I found it in the garbage bind of the manufacturer when they gave up model kit production some 4-5 years ago. This Bravo model was broken and needed a new elevator as well as an engine plus flying accessories. After restoration, the model was successfully maidened this last June in a C/L meeting in Madrid (Spain).pict0129.jpg

Thread: ESC overheating.
08/01/2020 16:16:58

The only ESC I have burned in my life was checking the turning direction of a motor without a propeller and at low speed.

It was with a proven set and the ESC smoked at once, without a second to cut!

Thread: Futaba type transmitter charging plug
08/01/2020 08:18:26

Don, for which Futaba transmitter is your multiplug charging lead is intended?

Knowing the transmitter, perhaps I may be able of fully confirming the sizes.

07/01/2020 12:20:17

"gangster" is right!

Futaba has 3 types of transmitter charging connectors depending on battery nominal voltage: one for 9,6V Ni-Cd/MH, one for 7,2V Ni-MH and the last, the thinner one, for 6,0V Ni-MH/6,6Li-Fe/7,4V Li-Po.

Then 18MZ and 32MZ radios have particular charger connectors different to those mentioned above.

Cuban8, excellent explanation which I totally agree.

Thanks Erfolg!

By the way, I am also a Do 335 lover and aside following your threads here I own all Monogram books on the plane and the Model Airplane News (USA) glow engine plans with the idea of building it someday.

Best Regards

Ian Hand from Hobby King says "We are living in a mad world right now....." A mad world they greatly helped to create, he forgot to mention.

They may be improving the website and trying their best for recovering the stock levels but, be sure, Hobby King will never be again what they used to be: they have altered so much the model market at the same time that flying restrictions make our hobby so little attractive that margins now are not interesting even for Hobby King!

At this moment, most probably, they are studying on reducing costs and looking for the product lines from which they get higher benefits: all other ranges we will to say "Good Bye!"

Not sure whether I've posted these two pictures before but they're still good for a laugh!

 

SPOT THE DIFFERENCE.

It is very clear, David. You made your garden a lot of more wider! laugh
