Title: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sanjayrai55 on July 16, 2015, 06:40:21 PM
Have made a couple of QB 20 Low Wingers - one of my favourite models. Decided to try out a shoulder winger, with a full 4 mm wire landing gear
Plans available on outerzone.co.uk

Specs:

Post by: b4ggu on July 22, 2015, 04:56:02 PM
How nice Sanj. Too good.  

What have you used for the decals?

Is it packaging tape or sticky trim?

Also I can see  you strengthened the bottom of the Coro Fuselage with bamboo BBQ sticks... very innovative indeed.

BTW where did you buy the vented prop spinner from? Was it HK??  I could do with ordering a couple of those!

Also do let us know how the wire undercarriage fare? You have always used aluminium ones in the past.. Are the from HK too??

Sanjay sir models are inspirational, making a model with all decals in 24 hours time is awesome speed, i know it takes lot of hardwork. Superb build sir.   :salute:

For landing gear, have u used steel spring wire or cycle spoke, and sprung nose wheel assembly

Regards
Prashant


Title: Re: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sanjayrai55 on July 23, 2015, 05:19:42 AM
24 hours is a long time, when working 2-3 hours a day!

For landing gear I bent 4 mm Spring Steel wire into shape. I got some nose gears built by a spring manufacturer based on a sketch I gave them. Could have bent them myself, but he had proper machines and heat treatment facilities

Nice stable flying sir,  {:)}.  
sir need some tips how to achieve straight taxing on ground


Title: Re: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sanjayrai55 on August 02, 2015, 05:45:48 AM
Prashant, firstly you need to have some steering - either a steerable nose or tail wheel. Then, do not give too large stick inputs. You can practise while taxying.

Hello Mr Sanjay. this is really beautiful model.
with 3536-1250 motor, 10 X 7 prop, 40-50A ESC, 10 gm MG Servo, 19 gm MG Servo, which other parts u have used. like hinges, push roads, landing gears, etc. step by step making will help all members who are interested in making similar model. 

also, do u suggest similar product with any local dealer.


Title: Re: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sanjayrai55 on August 14, 2015, 09:55:21 AM
1. It seems from your questions you have never built a corro model. Do not start with this - it needs advanced skills both in building and flying
2. Regarding Landing Gear etc. I suggest you read through the thread again.
3. For me to get a Corro model from a local dealer is not only offensive, it is the precise antithesis of why I build them


Title: Re: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sainath on August 14, 2015, 12:32:27 PM
ha sanjay ji ur right. i want to try it first time. but as u said this model will be difficult for me, can u suggest any other coro model for new user.


Title: Re: Pilot QB 20S for 2015 Sweepstakes - in Corro & Electric
Post by: sanjayrai55 on August 14, 2015, 01:06:52 PM
Do a search for Avispad on this forum. You will find all the information you need. And, please open another thread for these kind of queries


Title: Re:
Post by: rcrcnitesh on August 14, 2015, 01:20:08 PM
Or you can also build the corro pusher trainer by extremesports on rcgroups.
