Gliders aren’t really my forte. Aside from no engine (I’m a petrol-head 😉), and as much as I like the charm of circling with the buzzards and catching that thermal, I just don’t have the patience. Furthermore, and possibly as I also fly rotary wing, I cannot help but correct every little buffet and twitch made in flight. On a glider this is a no-no. A glider barely floats above stalling speed and every time you move the control surfaces you snap away at what little airspeed the model has and quickly loose altitude. Despite all this I keep getting the urge to try again and then this popped up on eBay.
The Precedent Electra Fly was designed in 1991 and offered an ideal introduction to both model flying and, still novel as it was at the time, electric flight. Construction was typical Precedent (now marketed under Slec) with a lite-ply fuselage that semi-assembled quickly in your hands. The idea was to allow absolute beginners to assemble a straight model without needing a fuselage jig. My trusty old jig was used as an insurance, but I can confirm that all the formers lined up perfectly.
The wings were another matter. After several decades in a box the spars had warped considerably and took a lot of painstaking steaming (and scalded fingers) above the kettle to straighten things out again.
Fully assembled this is a largish model with a wingspan of 2.2m. I opted to reduce the dihedral from the outset to that recommended for those who can already fly. One modification I did make was to glue the metal brace rod into one wing to eliminate any chance of it rotating in flight and altering the dihedral. Something that I uncovered after a search of old forums be an issue with this model due to the way the wing can, if going too fast, ride up at the front over the canopy seating.
The standard 600 takes it aloft adequately but converting to brushless would be straightforward enough as a 3660 inrunner is the same dimension as a brushed 600 can motor. The switch would be more for power efficiency than for any increase in power. This model was designed when electric flight was still novel and folding the wings would be a real possibility if things got too fast. There is no reason why I couldn’t keep a brushless dialled back and just reap the increase in battery duration. Cooling might be an issue with that fully enclosed motor block; especially as all the 3660 brushless motors I can find online seem to be fully sealed units aimed at cars and boats; brushless motors don’t work when wet.
