My model on photo below  has carbon D-box like F1J models.

(Click on photo to see enlarge image)

 I build F1J models many years, and I build F1Q model the same design. It is little bigger than tipical F1J.Wing span 2000mm,total area 30 sq.dm. flight weight is 440gr. Model without electronics have very low weight, only 220gr, other 220gr gives motor, battery  and controler.
Fuselage.

Tailbeam and stab.


Size the propeller is 30cm x 10cm, but I can adjust pitch to 15cm.See more in "News". Now this motor is apx.230W, it turns the prop 30x10cm about 8,500-9,000rpm. I will try this prop with different pitch.

Propeller.

Motor installed on "old 28mm" front part.                         

New "32mm diameter" front part

Now I see two main direction of F1Q models.

First - "F1C' style with  straight vertical climb.

Why I take so big motor and battery? As I know history of F1C the biggest models fly better! I find the battery with weight 85gr, under the rules. It can give 25-30A (1300mA x 20C). It is very important moment! I need a big current during take-off. Next step, I find big motor on 25-30A of consumption, this motor have big diameter and have big rotational moment, it's need for big propeller.Controller is Castle Creation 25A, but now I see that need 30-35A. The weight of this system show that F1J wings will be a little smaller than need for good gliding with wing load 12-14 g.per sq.dm. I little increase my F1J wing and made new mould for nose part of fuselage, becouse my nose part for F1J is too smaller for battery and controller. You can see photo of making front part in "Technology" page of my site.
Model covered by Micafilm.Price 550$ is for model with mounted servo without timer and motor. You can use in this model different tipes of timers, motor and controller.
Fuselage without motor.                                                         Best example of that style, Finnish Matti Lihtamo model   

Other dicertion supposemotor 100-200 Watt power and "F1B style" spiral climb. My model can be equip by such motor and add second servo for adjusting wing angle during climb.

From 2015 I begin to use "Sidus" electronic timers and EL in my models. Example of it installation in model.
