Thread: Which engine ?
11/01/2020 19:32:53

I fitted my Super Cub, 80.5" wingspan with the recommended 91fs and it was ridiculously overpowered.


Now powered with an ASP 61fs and it's just right. It flies in a scale manner on half throttle or less, but with a bit of extra power when needed.

Cheers GDB

PS The undercarriage is not the right one and has also been replaced with something more appropriate!

Look forward to hearing how you get on with it when it arrives.

Do let us know. GDB

Hi Gonzo, I have no experience of this receiver, but having read your post, I downloaded the manual from the Hobby Porter website.

The manual is written in the usual Chinglish, which makes it a little hard to understand at times, but I suspect it wouldn't be too hard to sort out if you had the receiver to hand.

For the cost, about £30, delivered (what about customs duty?) at the very worst it's an 8 channel D Series receiver.

The only worrying part is that the only realistic way to test it is to set the parameters and fly it and finger crossed you've correctly understood the manual!

Might just be tempted to experiment with it when I've got my current build completed.

Cheers GDB

Just for general interest my Nova, it's 66" wingspan incidentally, weighs 5lb 13oz without fuel, so around 6lb ready to fly.

Hi Christopher, I have a Nova 40 - it was my first RC model.

A couple of photos to show what it looked like brand new, and its current appearance after a refurb following an argument with a field of maize!!

Ripmax Nova

Nova refurbished

In the original it was powered by an Irvine 46 and now by an ASP 46, both two strokes offering about 750 Watts of power.

Alan Gorman is quite right when he warns against a motor that needs too large a prop as ground clearance is definitely an issue, especially if your grass is a little long.

Mine is currently flying on a 10x6 three bladed prop which gives good performance and adequate ground clearance.

Hope that helps.

Hi Martin, the plan is freely available here Speedy Bee

It shows the cog clearly.

Thread: X9D+ 2019 or Q X7S?
14/08/2019 20:08:23

Hi Kim,

Yes the Q7 comes with OpenTx.

The manual, written by Alex Datos is available here Q7 Manual

Don't know how it compares with the printed one from T9 but it's a good start.

Cheers GDB

Hi Anthony, welcome back to the fold !

If you have a look at the last item on this page **LINK** you will see that BMFA membership is reduced from 1st July, so you can join, and benefit from the associated insurance, without paying the full annual membership.

The BMFA club finder will help you find a flying club near you.

Hope you're successful.


Aha, beaten to it !!

Thread: Spinners for brushless.

Here you go **LINK**


PS While you're buying you should buy a few extra O rings smiley

Foxfan, if your shaft is 3mm then you really need a 3mm prop adaptor. A 3.2mm / 3.17mm / 1/8" one will not seat correctly on a 3mm shaft.

A 3mm adaptor is available here **LINK**

A spinner can then be mounted as per an IC engine.

Interesting reading here **LINK**

Might explain why they're offloading them for £1

Tony, what you have appears to be a 'New A3'

The manual is available here **LINK**

See the 5th and 6th items down, NewA3 and NewA3L

The difference between the two is the flight modes they provide, but they both like exactly like yours. Presumably you know which functions your is supposed to have (?).

Hope that helps.

Cheers GDB

Thread: Identification please!
27/02/2019 19:47:37

Jeff, very similar I grant you, but, it doesn't have the square (rectangular) horizontal stab of 'ours' and it's 2" short in wingspan!!

In the meantime I'm awaiting Robin's photos with bated breath smiley

Many thanks for your contribution and interest.

It looks like there are many, many models all of a similar theme, not surprising really as it's a classic trainer style.

Cheers GDB

Hi Robin, thanks for your response.

Is it possible for you to post a photo of your plane? It would be interesting to see it.


25/02/2019 20:55:13

Many thanks for all your contributions. laugh

This is the illustration which suggests that it might be a Kyosho model **LINK**

Mike, your unknown model is very similar to 'ours', but, as Percy points out yours has a swept back leading edge whereas ours is square, and the wing seat on yours is raised - ours isn't. The fin on yours is very much the same, but yours has a strake.

The wings (54" span on ours) appear to be identical. Incidentally, if the fuselage is inverted the wings fit perfectly, further suggesting it could be built as a low wing model. Perhaps this explains the mid mounted tail.

Martin, I suspect this is a kit build, the formers look to be machine made (the firewall has F6 written on it, not printed).

The covering, although reasonably applied, is not to the standard we would associate with an ARTF model, and the fitting out certainly isn't!

The current CoG is 25% of chord, so we'll leave it at that and see how it goes wink 2

Cheers GDB

Can any of you highly knowledgeable chaps identify this model? It has 'Kyosho' stickers on it, and 'Hughes 500' sticker. but I don't know if these are really relevant.

I've looked on-line and it could be something like a Kyosho Berballa (which was a kit which could be made either as a high-wing or low-wing plane), but, the vertical stab is wrong.

It was bought for a member of our club by his daughter.

It was in a poor state of repair and I have spent a bit of time refurbishing it.

Please don't panic about the wing bands (!), I used rubber bands purely to set the wing and I haven't acquired any proper wing bands yet.

It's powered by an OS FP40 which is well-used but runs quite well.



We look forward to your suggestions.

Thanks GDB

Tosh, how about this:

or a 36 if you want a bit more grunt

Hi Dave, whilst I can't offer any suggestions at to your lack of elevator response, I can make a suggestion ref. a new set of wings for your Pulse XT 60.

When an attack of dumb-thumb reduced my Hobby King Soar 40 from this

HK Soar 40

to this


I dissembled the wreckage, produced a set of plans,


and built a replica of the original, using all the original hardware. It flies just as well as the original plane.

It's not difficult to do as you can see how the original was made and mimic it.

As you only need the wings it shouldn't take too long.

Food for thought?

Cheers GDB

Thread: Flying Aces Sportster
10/01/2019 17:35:38

FB3, if you look here **LINK** there are, rather poor, images of the pages from the magazine describing the Sportster.

I contemplated building one of there as I have a spare OS26FS looking for a plane, hence I searched the net for info.

In the end I think I may build something different, but, if yours turn out OK I may reconsider!!


Aha!! Just clicked on the above link and it does indeed display the pages in question, but, they're not exactly readable!!

If you're interested, send me a PM with you email address and I'll send the original files to you.

Martin, could this be what you're looking for?:


Mostly sports type models, but a couple of warbirds thrown in.
