Wonderwings Phoenix-100 2.5m glider build


Recommended Posts

I acquired this kit from our club, Aberdeen & District Soarers, mid 2020. This was my second balsa glider build. It has blue foam wings with spruce spars all the way through. Here's the spar sandwiched with a balsa core. Here's the only photo of the glider I have which is from the box of te kit..

Started with the wings.

 

Main spar is glued in between the two halves of the wing panels with ply reinforcers at its root.  The wing joining tubes were epoxied on place on the plan template before its is cut into two halves ensuring full alignment and application of the first dihedral.

Here's the tube in place after cutting into two halves.

Wing cheeks are then prepared altogether for alignment.

The leading and training edges are glued in place.

After completing all the TE and LE gluing, I added the ply wing root cheeks/cappings and added the tubes for the second thinner connection/guide rod.

Then the fuselage construction followed.  The tail assembly and the all moving tail (AMT) were constructed as integral part of the fuselage. The bell crank was shaped. The fixing point for the AMT was reversed (front hole is fixed)

Fuselage was constructed with all the internals installed (snakes, servo mountings, servos and battery holder. It was then shaped, rasped, filed, filled and sanded (80/120/220/400). The hatch was cut prior to fibre-glassing.

God help!! This glassing and painting required so much more elbow grease than just covering with platic coverings (Solarfilm etc).. Although the end product is more robust and damage resistant I will still preer coverings.. Anyway it hass been a good learning... The fuselage was glassed and sanded (220/400 wet) between 6 coats of Poly-C.. And it was painted with white spay paint (PlastiKote gloss white, 3 coats with light 400/600 grit sanding in between).

Although it was my first brown paper covering, I was impressed with the successful outcome with 50% dilute PVA glue. It increased the stiffness and robustness of the wings significantly. I applied the white vinyl polka dots ot the topside and white vinyl st ripes at the bottom of the wing in order not to use any other covering/paint etc.

The numbering and club decals were added. The plane was CG tested (78mm from the leading edge) on my home made CG stand.

The short nose and craped space a the nose made the balancing a struggle as I needed 250 gr of ballast.. I casted a shaped lead ballast and glued it at the nose leaving just the sufficient amount of space for the NiMah batteries, receiver and the switch.. The end result AUW  is 1564 gr including ballast...

I did not add any adjustment weight to equalize the weight of the wings. This was sorted out in the initial trim during the maiden flight.  The bird was read for the maiden on 15th March 2021....

Here's the glider in its final livery:

The maiden flight took place on 15th March 2021 on the Brimmond Hill, Aberdeen, after the relaxation of the COVID19 restrictions in Scotland for outdoor activities.

A great flier eventhough it has only 2 ch control (rudder/elevator).. AMT travel was reduced to 60% with 30% expo.  here are some snap shots..

The videos will be loaded once I reduce their sizes or put on Youtube..   

 

I really enjoyed this build and learned a lot.. First AMT, first brown paper, first fibre-glassing... I thank my fellow soarer Norrie Kerr and the modelflying forum community for their support and assistance with a few questions I raised.... and to Derek Robertson for the training and model trimming he has provided patiently..

I had a wee incident and ended up repairing this birdy. The nose section was damaged while the tail end, wings and wing roots survived intact.

I added additional doublers and extended the nose by 35mm adding a ballast compartment at the nose. Not worried about the additional weight as this reduced the balancing weight I used. I used the shots from my shut gun cartridges. They were very handy to feed through the plastic tube I added to the ballast department. I also added some glued into the nose section itself.

 

Here are some photos of the the damaged bird and the repairs:

Complete rebuild of the nose section, except the tip! I used the same hardened tip..

You see here the ballast compartment and the feed tube.

Rejoined the front and the tail sections.. and re glassed the new part with 49gr cloth and PolyC:

It went onto flying again on 22 May at Cairn O'Mount.. It is a stable and well behaving flier.. It just does not want to come down easily..

I have a phoenix 100 2.5 wonder wings if you would like it. I had it given to me, I don't want to use it as I don't want to break it. I'm from Cheltenham

Hi Andy

I have the plan but it does not have the wing, which is cur from foam. You may do cut it using the wing rib profiles. If you like I can get it copied and send it to you at cost.

Regards. You can PM me.
