Scale / BIG Electrics

Thanks Fred,

Yes, I want to try a scale approach with the tow hook, with the ability to release the tow line just in case.

A tug pilot here in the Darling Downs Gliding Club some years ago thought he had released his line (not) and commenced a beat up of the control van and adjoining tent with disastrous results - lucky no one was in the van or tent at the time. He was sacked, suffice to say.   :oops:

I am going to have to search the net for towhooks!

Where can I get the rules for Retroplane? Sounds like a great idea!

Cvanscho - that Breguet is the Breguet 901 Choucas.  I seem to remember plans were available either in Traplet or Argus mags - RCM&E or Radio Modeller some years ago.. :?

Hi Fred,

Love your work with the Opel, prompted me order one - here in Aus it is within our CAR's to fly rocket powered aircraft so I wouldn't mind finding out wahat you used in yours. Black powder G80's might be fun! Bit expensive, though - maybe for effect only.

Back to the Cub - Hangar 9 recommend the E 110 but are skimpy on fitment details so I have engineered a motor mount out of ply. The only real help in the plan booklet for the Cub was the 6" dimension from the firewall to the prop driver. One thing I will do if the combination is powerful enough to do aerotow is to run a cable from the wing spar rearwards to the securing fixture for the tow bridle mount like the full size tugs.

Before going electric big time I added up the cost of motor, batteries, BIG 10S LiPo charger and balancers PLUS flight batteries and didn't come out much more expensive than an Enya 155 4S.   At least I can go 5S packs and even out to 5350 mA with the new Hyperion Packs. Nitro isn't cheap and I could have gone Zenoah but the idea of flying with electric with only the hassle of charging batteries appeals to me. No fuel, no mess, unless I crash....

A few years ago I purchased plans for a Fournier RF4 and it screamed out for electric. Those plans are lost in the mists of time and house removals post separation but I have ordered the Aero Naut RF5 with the full intention of using the same motor/ESC/battery combination as the Cub. Now, just have to do extensions to my shed...

In the process of converting the Hangar 9 1/4 scale Cub to electric - I am fitting an E - 110 outrunner, 2 Hyperion 4250 4S in series to give 28 volts and a Hyperion Titan 90 ESC. Anyone else out there doing something similar?  :shock:
