The 91 failed and is replaced on warranty by HK.

Unfortunately they do not say what was wrong, but I suspect a broken con-rod.

My Extra now has possibility to have ASP 61 2 Stroke or the new 91 4 Stroke fitted.

I checked and apart from the silencer clearance, mount bolts spacing are same. Funny though that specs say not !

Looking forward to her back in the air.

Recently a tussle has been on here about use of tapered reamers and the misconceptions of some about them.

APC Prop company recc'd tapered reamers for very good reason and go to the level of explicit instructions how to ream a prop.

OK lets look at Tapered Reamers.

There are basically 3 types ....

Hobby shop variety which double as 'cutters' for Lexan and various plastics. Doubtful quality and blunt easily.

Repair / Carpenters Reamers. These are generally in Carbon Steel and an excellent economic long lasting tool. Available in various tapers and size ranges.

Machinists precision Reamers usually also in Carbon Steel and Case hardened. Produced for precision work in hard materials. The most expensive of the reamers and in reality unnecessary.

As APC show in their illustrations, the taper is purely to allow shaft to pass through and for rear shaft hole and hub to center correctly. They eveeven illustrate how to over-ream and insert shaft ring to fit shaft exact.

This shows that the second type of reamer is fully suitable for the job.

I have reamed many props this way and always found it to work as designed. I have even balanced props before reaming to check if any change after .... no change at all. Balance remained correct.

I have placed my Reamer on a dial meter and found that the flutes are accurate and there is no reason to expect the cut would be out of true.

Please note that I do not discuss stepped reamers - they are fine and some are...Continue Reading

Finally the ASP FS91 arrives and with slight modification to firewall - is fitted. The cylinder head is not far of same position as the old OS FL70 so all I needed to do is cut a new needle hole - this time is much better being at top instead of underneath as that 70.
As my usual practice ... low speed needle left as factory, high speed set at 2.5 turns to initial start. Finger over exhaust, I had removed the choke gear as there was not enough room behind to firewall, flipped till I was cconfident fuel was to carb. Connected glow and flipped by hand - she kicked hard ! Decided to play safe and put starter on her. She started instantly. Few clicks in on high speed needle and she was running nice, rich a touch for first time. Ran about 1/2 tank through at various throttles, then let her cool. Prop is a 14*7 APC glow.
Started her again ... then put her in the air. I prefer to break in my engines in the air.

She immediately showed how much better thathan the 70 she is. Even though I was careful with needle setting and throttle. This is one model that I know will improve as that engine beds in.

So what is the other model ? Its the Hyperion 44.4" electric Yak 55. Sold by Hobby King. I fitted a 3542 1000kv with 45A ESC ..... initially a 10*6 prop as I was waiting for the 11*7 I intended to use.
I decided to split the elevators with 9gr metal gear servos, rudder with 16gr, ailerons with split 12gr's. The aileron servos immediately gave problem as they are digital and I...Continue Reading

So I get home from Crimea and I end up with a few presents to myself for such work .... I buy a 2nd hand Extreme Flight Extra 58" 300 .. and a Kyosho Pitts S2c .... now they are fun and fly well ... Extra needs a better engine than the weak OS 70FL though, (An ASP 91FS is on its way !).
The Pitts is just brilliant - well powered, balanced out nice with the Irvine 53 2str.

Friend and I decided to take a 9hr drive to Warsaw ... visit a hobby shop ! Yep - we are that mad... Friend left with nothing - I left with an EPP Profile Zlin 50 - to practice my 3D on ...

3D ? Well after 45 odd yrs of general RC flying - I've finally decided that it's time to try out this 3D lark. The Extra 300 with the coming suitable power plant is well capable - so the Zlin EPP job is so I can practice without having to risk my Extra ..

I have also as a birthday present (I have b/day Jan 02), decided to treat myself to a Yak 55 ... this is not so much a 3D machine - but has potential ... I have always liked the look of the Su's and Yak's - so different with their tubular style fuselages.

So wish me luck on the new highway !!

Now onto a pet annoyance I find ... self-opinionated experts who think they help newbies but all they do is trot out formulae, technical bumf that really is not useful to the poor guy who wants a simple answer. Yes - I get it in the neck when I fire back at them trying to help the poor newbie ... that's my cross to bear. But maybe one day these 'experts'...Continue Reading

On Aug. 22 - I finally got out of Crimea, by jumping a ship to Istanbul.

Once home - things started well but then I find myself in hospital instead of flying. My abdomen is so painful, I cannot sleep, cannot bend over to pick up anything. Diagnosed with Inflamed Bowel. 4 days of treatment, no food only water ... and they let me home.

Next the car starts playing games ... turns out vacuum side of fuel system is shot ....

I'm asked if I will return to Crimea ... so I contact Russian Consul for multiple visa to avoid same problem as previous .... first told - OK no problem.
While my passport is with them - I get call from UK telling that roof of my holiday home has been ripped off in bad weather ....

2 days later - consul decides I cannot have visa ! So passport is returned and I'm now set to travel to UK to sort out the roof.

As soon as I set travel - consul then let's me know that I can have visa IF Moscow agrees ....

So now I have agreed with them to get Moscow decision ... while I visit UK.

At least once I left hospital - I have managed to get some flying in. Even to start building a 71" aerobatic sport model for gasoline engine.

I just hope that rest of year improves !

Well - I supposed it had to happen sooner or later ... I'm one of those guys who will do or go just about anywhere .. so I end up in Crimea ! FInally I bomb out .. stuck ! I've been with rebels in Rwanda .. up Saigon River ... but always managed to squeeze way out.

Anyway - it's now edging into 3 months and I'm getting withdrawal jitters not having my flying fix !

When I have time away from some of the people I have to suffer !! - I of course delve into RCG and Wattflyer ... but of course another passion is planning next model.
I hate being inactive ... so I have been working on large plans of a sport model. For either E or IC power. 70" span ... 4 - 5kg weight.

The original plans by Colin Usher have been modified to increase area of ailerons but shorten their span so flaps could be created. The build will have composite foam / ply construction so that the ply strength will be offset by foam top-decks etc. Foam ribs where structure is not subjected to wing bolts or high stress.
My intention is to fit a 15cc Gasoline engine ... and that means keeping her light. If not it would need a 26 - 30cc ....

Well ... all I need to do is get home !! Fingers crossed ..

News coming in from our B.U.S.A Correspondent about action taken over the Christmas period ..

Report :

Mr. Iam Killjoy, rep. of Dept of Homeland Security just released information about an attempted unauthorised intrusion in US airspace. Despite repeated warnings to the air-vehicle detected to turn away and desist from entering US airspace, the only replies received ran to the sound of YO HO HO.

DoHS then initiated Operation Shoot the B'd by deploying it's latest Stealth Interceptor

This latest weapon in the arsenal of DoHS being controlled by the new secret Mobile Command Stations :

The intercept proved successful despite initial arming problems of the Stealth Interceptor :

How do we do it ... we spend years liking a way to do things and then we start to change. Bit like all your childhood - you don't eat your greens then later you eat the lot !

I've always been a power hungry modeller ... with odd moments of lazy models. Fast aerobatic jobs ... warbirds .... etc. Last few years enjoying EDF's having been in the early days of DF and all the problems we had then ... Enjoying pushers - a model type I used to dislike.

Now ? I'm looking more and more at small compact stuff ... stuff that can flit around the back-yard ...
The guy who converted the Dollarstore Gliders .. the guys with the Heli Bricks ... and of course the little WLToys micro heli's ...

Strange how we evolve ...

I do still have pet projects on the go - the Twin Parkjet ... NiJet .... twin EDF Concorde .... various that need completion before I move on too far !!

I really am looking fwd to a great 2014 ... and building / flying some more interesting models, as well as helping as many as I can with what little knowledge I can muster.

I'm getting a little disillusioned at times with the bias and kicks introduced into some posts ... OK - I'm no golden boy and I dish out fair share, but basically in retaliation to some silly remark passed at me.

Being older - I suppose I can shrug .. make a reply .. then walk away not really fussed about it. That's true and what I do. But I think about the others who read the exchange. The people who are looking for answers, tips, camaraderie ...

It will happen of course with such a large forum membership, law of numbers means that there will be clashes whatever the rules.

Why I post this ? Maybe it's a plea to others and myself to cool it .. take forum life as artificial and often misread ...

Good airs to all ... and ignore this old fart !!

One of the aspects of RC modelling I like, is that we can try out all different types of models and designs.
I'm not a fan of profile planes, but some are not fans of what I like ... it's a mixed world.
Recently I have rebuilt a classic from the 1980's - a Biplane that was designed specifically for a RC company to display it's products. This I will refine, tune till it performs just the way I want ... hopefully others enjoying the spectacle of it's flights.

Need for Speed has literally ground to a minimum since demise of the Parkjet ... people holding on to their last airframes. The hunt for replacement continues.

Pushers seem to be steadily increasing in popularity judging by posts ... and EDF's are getting better all the time, with so much work done by RC'rs and then posted up on forums.

It's good to see that new faces - especially young are entering this hobby, I think that costs based on Chinese production and foam is big reason for this. It's also nice to read of oldies returning to the hobby ... like I did !

Me ? itching to see what is next !!

The Need for Speed group has produced some great vids and efforts by many .. but sadly it now appears that our mainstay model - the Parkjet is no longer produced. Various alternatives are under consideration, but I would like to suggest to others that we try to keep as near to the PKJ so we can use all the hard earned info / data as well as the power set-ups.
The Twin PKJ - the Beast as I nicknamed it at home sits still unflown. I have to admit that she frightens me ... but she is unflown due to other factors ... weather, work, change of gear after testing etc.
I know many are waiting for the maiden and what she performs like ...

Other avenues have been pursuit of more performance from my EDF collection, along with friends donating crashed models to my hangar ! These have led to interesting saga's ... the F16 and Twister are suffering UBEC blues from bad UBECs not handling the 5S power supplies.

Crashing has returned to my repertoire ! One of my last outings resulted in 4 models crashed ........ one even hitting friends BMW !

Well we soldier on ...

With the advent of computer radios and programming - I think some of the old skills are being left aside.

I have spoken to various and I read posts, one guy complained that his computer radio had mechanical trims - meaning that the model memory didn't remember the trims for a specific model. I have a similar situation on my Heli radio. Model memory, programming - but trims are mechanical.
I replied to him that surely he reset control links to bring trims back to centre on his Tx ? The look I got was one of "?".

An out of trim model can be flown well by a new radio as you program out it's trim faults. But is that right ? In my opinion it is not. I believe that trims are a temporary measure to be able to find out what is needed to correct on the model.

It's hard for me to lose old habits .. but I have to admit that I do at times get lazy because of the computerised digital nature of my main new radio .. it 'encourages' laziness in trimming etc.
I must sort out that 6 clicks of left aileron that's still there from 3 months ago !!

It's been a hard slog - harder than I expected to get back into RC flying. And it's also surprise that same faults, memory's re-occur with my return. I still get that .... OK - now I have to land queezy feeling ... I still prefer left hand circuits to right ... I still prefer to take-off right to left ....

I suppose old habits are hard to kill of. But today we have sims and a much easier route with electrics. Gone are the days when you arrived at site ... got all set-up to start flipping IC engine props ... there were days when that engine just would not start for no apparent reason. Now it's switch on and go.

I would like to get back to IC flying again - but will wait till I have found best venue, got my fingers back to previous skill I had ... I also want to venture into EDF ... that can wait a while also. I dabbled in IC DF when it was a new style .. I knew some of the known names who pioneered much of it in UK and also met various from States - Jet Hangar Hobbies Larry as example when he used to visit for Demo's at venues.

Heli's are taking up most of my time at moment due to flying area not suited to fixed wing. And proving to be just as difficult as when I flew them before ...

Well - glad to be back in the RC lark ...

Just created a group listing for FlySky / Turnigy / Imax / Eurgle branded Rc systems.

As an addition to forum - to collect together helpful data and knowledge to help all owners get the best from these budget systems.

.... hopefully it can become a real fountain of knowledge to all who venture to buy these systems.
