I would like to share with you my experience with this plane I bought from HK. It’s a Venus 0.40-0.46 glow trainer ARF.

I think this is the Chinese copy of a plane called WOT Trainer from Ripmax originally built in UK.

The Chinese copy is really cheap (75$) but also really poor in manufacturing and materials. There is so many things I don’t like that I decided to perform some modification on it.
First of all I installed a real tail wheel from Dubro, the modification is quite easy to do and hopefully I will be able to set up the CG easily (maybe just moving the battery).

The second mod I would like to perform is about the ailerons. I really don’t like to have one servo in the middle of the wings. When I checked the control throws I noticed that the left aileron is moving less compare to the right one. I mean, the assembly is so imprecise that left and right are working whit different angles. For this reason I decided to add a servo for each aileron. I will built a support in balsa and then I will cover with a stripe of white monokote.

Above you see the wing of the Avistar and below the wing I would like to modify (same way as the Avistar).
Now I have some questions, I was thinking to add also the flaps and instead of an OS .46 an OS .55.
- Do you think the flaps are useful for this kind of plane?
- I was thinking about the OS .55 because the plane will be heavier to the original one:
OS .44 => 1.65PS, 1.67HP/16000 RPM
OS .55 => 1.75 PS, 1.68 HP/16,000 RPM
What do you thing about the increase of power?
Many thanks for your suggestions :)
